Energy and exergy analysis of a SI engine fueled with anisole and isobutyl acetate with super-premium gasoline

The rising demand for fossil fuels is rapidly depleting the limited sources of crude oil, leading to harmful emissions upon combustion. Consequently, developing sustainable and environment-friendly alternatives to fossil fuels has become imperative to reduce dependence on them and decrease harmful emissions. In this study, the performance of different blends prepared by mixing biofuels with super-premium gasoline (SPG) in a spark-ignition (SI) engine at different speeds is investigated through energy and exergy analysis. Three biofuels, namely ethanol, anisole, and isobutyl acetate, are considered, and these biofuels are blended with the base SPG in volumes ranging from 10% to 30%. Letters G, E, A, and IBA are used to denote SPG, ethanol, anisole, and isobutyl acetate, respectively. Experiments were conducted on a three-cylinder, four-stroke SI engine with varying speeds. The results of different anisole-SPG and isobutyl acetate-SPG blends are compared with SPG and ethanol-SPG blends. The results of the energy and exergy analysis reveal that the maximum brake thermal efficiency (BTE) and exergy efficiency are achieved when the engine runs at 2500 rpm for SPG and different blends. Furthermore, the engine emissions of carbon monoxide (CO) are found to be lowest at this engine speed. It is also investigated that the maximum BTE and exergy efficiency are obtained for AG10 and IBAG10 blends. The maximum BTE of AG10 and IBAG10 are 31.23% and 30.82%, respectively, while the maximum exergy efficiency of AG10 and IBAG10 are 24.37% and 23.82%. At 2500 rpm, the blends AG10 and IBAG10 showed a slight reduction in BTE by 1.72% and 3.02%, respectively, compared to SPG. At the same time, the exergy efficiency of the AG10 and IBAG10 blends is reduced by 1.5% and 3.72%, respectively. On the other hand, the IBAG30 blend showed 7% lower emissions of CO and NOx compared to SPG. Among all the blends, EG30 showed the lowest reduction of HC emissions by 14% compared to SPG. Additionally, the sustainability index values decreased by 0.47% and 1.19% for AG10 and IBAG10, respectively, compared to SPG at 2500 rpm.

Research Progress of Dual‐Site Tandem Catalysts in the Preparation of Multi Carbon Products by Electro Reduction of CO2

AbstractThe era of an energy economy driven by “carbon neutrality” is putting forward stricter requirements for the use of carbon resources and the governance of CO2. Electrochemical reduction of carbon dioxide reaction (CO2RR), driven by renewable energy, is a practical energy storage technology with broad application prospects. It can reduce CO2 into carbon‐based fuels and chemical products. Among them, multi‐carbon (C2+) products have higher energy density and larger market size, and can significantly reduce the global demand for fossil fuels and close the artificial carbon cycle. Introducing additional active sites into Cu‐based catalysts to prepare dual‐site tandem catalysts can regulate the electronic and geometric structure of the catalysts, break linear scale relationships, reduce reaction potential barriers, and bring superb and stable catalytic performance. Various types of dual‐site tandem catalysts are developed, and the understanding of the tandem effect is pushed to a higher level. This paper reviews several typical dual‐site tandem catalysts: atom–atom dual‐site tandem catalysts, atom‐particle dual‐site tandem catalysts, particle–particle dual‐site tandem catalysts, and heterogeneous interface dual‐site tandem catalysts. It then deeply analyzes the reaction mechanism and research progress of these advanced catalysts in CO2RR. In addition, the challenges and opportunities faced by such catalysts are also discussed.

Second-generation biorefineries: single platform for the conversion of lignocellulosic wastes to environmentally important biofuels.

The continuously increasing demands for various fossil fuels to achieve the day-to-day needs of the human population are growing and causing adverse effects on the environment and leading to the depletion of their natural resources. To overcome such drastic problems and minimize the production of greenhouse gases, lignocellulose biomass, which is an abundant and bio-renewable source present on earth with excellent properties and composition, has been used for decades to develop biofuels that can easily take over the place of conventional fuels. Lignocellulose biomass comprises polymeric sugars, i.e., cellulose and hemicellulose, and aromatic polymer, lignin, which are responsible for producing various bio-based products. However, utilizing lignocellulosic wastes for such purposes is needed but their recalcitrant structure makes it difficult to achieve their full usage. For this, several pretreatment approaches are developed to loosen the complexity between sugars and lignin. In some way, few of the conventional pretreatment methods are expensive, non-eco-friendly, and produce undesired by-products, causing a lower yield and reusability of enzymes used in the reaction. Utilizing novel pretreatment strategies that are cost-effective, help in increasing the yield of products, and are environment-friendly is required. Thus, incorporating nanoparticles and nanomaterials in the development of pretreatment and other strategies for the production of bio-based products is currently thriving. This review is designed in such a way that the readers can easily get brief knowledge about the production of important biofuels developed within second-generation biorefineries using lignocellulosic biomass. It also summarizes the importance of nanotechnology in different steps of biofuel development.

Innovative Feature Analysis of Electric Vehicle Technology, Charging Infrastructure, Power management, and Control Methods

Lowering the dependence on fossil fuels and reducing pollution from greenhouse gas (GHG) emissions is incredibly achievable through electric vehicle (EVs) technology. EV technology is an innovation that uses electricity, rather than fossil fuels, to power and refuel (recharge) vehicles. The adoption and development of EVs should lead to a decline in future demand for fossil fuels, which are finite in supply and exhaustible. Inherent challenges in EV technology, such as inadequate supply of critical minerals, power grid overload, battery technology constraints, extended charging durations, insufficient charging infrastructures, high initial costs, and limited driving range, must be addressed. The technology of charging infrastructures cannot be over-emphasized in EV technology. EV technology, charging infrastructures, vis-à-vis the impact of their integration into the grid is investigated. Effective control strategies and power management systems (PMSs) are required to optimize energy use to improve EVs' efficiency and lifetime. This research uses comprehensive analysis methods to assess various control strategies, PMSs, and their effects on EV integration into the grid.

Demise of fossil fuels part I: Supply and demand

According to United Nations , the world needs to reduce the emission of CO2 and other global warming gases by 45 % by 2030 and to negligible amount by 2050. According to UN, this is necessary to keep the goal of keeping earth temperature not exceeding 1.5 °C compared to pre-industrial level temperatures.To achieve this objective means reducing the fossil fuel consumption. Fossil fuels are largely responsible for emitting CO2; therefore, without significant reduction in fossil fuels consumption by 2050, the net zero emission by 2050 is not possible.One argument advanced in support of reducing fossil fuels consumption is limited supply. Using the principle of “Peak Oil Theory,” proponents state that fossil fuels is a limited resource and the world will simply run out of it. Based on the available data, we demonstrate that supply of fossil fuels is relatively abundant, and we will not run out of fossil fuels in near term. Using shale formations as an example, we demonstrate how the success of drilling horizontal wells with hydraulic fractures have significantly increased the oil and gas resource available for exploitation. To reduce fossil fuels demand, the available solutions include improving energy efficiency, reducing subsidies on fossil fuels, imposing carbon tax and life choice changes. We discuss some of those alternatives. Fossil fuel supply is relatively abundant and only possible solution to reduce the consumption is to reduce the demand. By comparing developed countries' consumption with developing countries’ consumption, we see a pathway where growth in GDP can be achieved without significant increase in fossil fuels consumption. Because of efficiency gains in energy usage, GDP in developed countries continues to grow without increase in fossil fuels consumption. Faster we reach the efficiency stage in developing countries, easier it would be reduce the fossil fuel consumption in the world.

Enhanced super-ultra-deep photocatalytic oxidative desulfurization by titanium-activated metal-organic frameworks nanophotocataltyst

Addressing the escalating global demand for fossil fuels and the urgent environmental concerns associated with their use necessitates the development and implementation of efficient and cost-effective techniques for the removal of sulfur compounds. In this study, titanium-activated MIL-101(Fe) was utilized for the removal of organosulfur compounds through the photocatalytic oxidation desulfurization (PODS) process. The coexistence of active sites with titanium and iron resulted in an ultra-deep desulfurization. The impact of titanium loading was assessed, with TxML representing the ratio of Ti to Fe (x = 1, 1.5, and 2, respectively). Nanophotocatalysts were fabricated by solvothermal method. The physicochemical properties of the new materials were investigated by performing XRD, TEM, FT-IR, FESEM, EDX, UV–Vis DRS, PL, GC–MS, ESR, TGA, transient photocurrent, and nitrogen adsorption–desorption analyses. The effect of titanium loading on the structure, and performance of photocatalysts in the PODS reaction was investigated. The reaction parameters were optimized for maximum efficiency. Under optimal conditions of T2ML loading at 1.5 g/L, a volumetric solvent to fuel ratio (S/F) of 1, and a temperature of 50 ℃, T2ML shows the best performance by removing 100 % of dibenzothiophene.Kinetic experiments revealed that the PODS reaction obeys a pseudo-first order equation, and activation energy is 47.08 kJ.mol−1.

Boosting photocatalytic H2 evolution in B-doped g-C3N4/O-doped g-C3N4 through synergistic band structure engineering and homojunction formation

Photocatalytic hydrogen production is a promising method to address the increasing energy demand and depletion of fossil fuels. Among various photocatalysts, g-C3N4 (CN) has attracted significant attention due to its favorable properties and tunable band structure. CN-based heterojunctions have been developed to enhance photocatalytic efficiency through improved charge separation via interfacial charge transfer. However, traditional heterojunctions formed between CN and other semiconductors often face challenges related to material compatibility and stability. In this work, we explored the formation of homojunctions, which involve identical semiconductors and offer superior charge separation and electron mobility due to perfect lattice matching. To further enhance individual oxidation and reduction capabilities, we employed band structure engineering through B doping and O doping. The homojunction between B-doped CN (BCN) and O-doped CN (OCN) was successfully synthesized using simple electrostatic self-assembly, resulting in significantly improved hydrogen production of 519.3 μmol g−1h−1 compared to BCN (34.7 μmol g−1h−1) and CN (167.2 μmol g−1h−1). This approach enhances visible light absorption, charge separation, and mobility, demonstrating the potential for developing advanced CN-based photocatalysts for various applications.

Sustainable algal biorefinery: A review on current perspective on technical maturity, supply infrastructure, business and industrial opportunities

The environmental problems associated with the use of fossil fuels demand a transition to renewable sources for fuels and energy. A biorefinery approach has often been considered and microalgae as a feedstock has been pampered for its numerous possibilities to produce biofuels. Depending on the species and cultivation conditions, microalgae can produce fats, proteins and sugars. These raw materials can thus be utilized in the production of biofuels, bioenergy and biochemicals. For this reason, algal biofuels are considered as sustainable and renewable options for climate related challenges. However, there are many issues such as supply infrastructure, business and refinery opportunities, as well as their efficacy, tied to sustainable production of these energetic materials from algae. Thus, technical maturity, scalability, energy and material balance demands coupled with cost, nutrient resources demand, certification and legislation are needed to demonstrate the biorefinery opportunities of algal biomass valorisation. This paper therefore recommends that various consortiums tasked with algal biofuel projects should be chosen for a more holistic integrated multidisciplinary approach to address the advancement of algal biofuel technology.

Optimal design of sizing and allocations for highway electric vehicle charging stations based on a PV system

The world’s demand for fossil fuels has recently increased significantly for both transportation and electric power generating sectors. Using these resources not only results in high costs and depletion of them but also increases greenhouse gas emissions and pollution. The electric vehicle (EV) market is growing globally, aiming to face climate change due to greenhouse gas (GHG) emissions and to reduce reliance on fossil fuels. However, the long charging time of EVs and the shortage of charging outlets limits the global adoption of EVs, especially on highways where the problem of accessibility to the electricity distribution grid appears. These issues can be faced by the good planning of charging infrastructure. However, this planning is a multidisciplinary field that includes electricity generation, transportation networks, EVs’ characteristics, and driver behavior. A methodology to provide the optimal locations and sizing of electric vehicle charging stations with their own electricity generation and storage using photovoltaic (PV) and energy storage systems on highways considering different factors is proposed in this paper. This paper takes a section of the western desert highway in Egypt connecting Assiut and Cairo cities as a case study. Four scenarios are proposed for the design of EV charging stations’ locations and sizing which are centralized charging stations, two-way charging stations, utilizing oil stations’ locations, and distributed fixed sizing charging points with a comparison between them. The work also discusses the potential effects of highway slope, wind speed, and number of passengers on the location problem. The results can be used to optimize the design of EV charging stations along highways for a completely sustainable system.

Vapor-phase reduction synthesis of N, S co-doped graphene/MWCNT hybrid membrane for all-solid-state supercapacitors and adsorption of organic pollutants

Owing to the limited reserves of fossil fuels, many researchers are focused on seeking advanced materials to relieve the drawbacks caused by the imbalance between the supply and demand of fossil fuels. In this study, a N, S co-doped graphene/multi-walled carbon nanotubes hybrid membrane (GMHE) was synthesized by flow-directed assembly followed by vapor-phase reduction. The resulting hybrid membrane not only exhibited excellent capacitance performance, but also good adsorption capacity for organic pollutants owing to its high electrochemical activity, well-developed pore structure, and rich surface state. The assembled GMHE all-solid-state symmetric supercapacitor delivered a high power density of 6000 W·kg−1 at an energy density of 16.0 W·h·kg−1 and superior capacitance stability (retaining 97.2 % of its initial capacitance value at 3 A·g−1). The adsorption capacity of the GMHE for organic pollutants was 50 times (chlorobenzene) its own mass. In addition, the hybrid membrane exhibited remarkable reusability over in adsorption–combustion cycles. The judiciously designed bifunctional membrane material developed herein can be directly applied in energy storage and oil pollution cleanup, supporting sustainable economic development.

Renewable energy and institutional quality effect on carbon dioxide emissions empirical study: a multi-factor analysis

ABSTRACT With the development of society, the development of industry, the demand for fossil fuels and metal ores has also increased, leading to the uncontrolled exploitation of natural resources and their further reduction. Due to the widespread use of fossil fuels, carbon dioxide emissions are increasing every day. This is a common concern of many countries. In countries along the Belt and Road, carbon emissions have increased due to rising incomes, financial growth and urbanization. This paper investigates CO2 emissions in Belt and Road countries, using Stochastic Impacts by Regression on Population, Affluence, and Technology Framework and Driscoll-Kraay regression model were used for multi-factor analysis. Research shows that more renewable energy can help improve the energy system and reduce carbon dioxide emissions. In addition, research shows that the better the quality of the institution, the lower the carbon dioxide emissions. The government should also improve the system to reduce pollution from the second.

Tetraselmis species for environmental sustainability: biology, water bioremediation, and biofuel production.

With increasing demand of fossil fuels and water pollution and their environmental impacts, marine green microalgae have gained special attention in both scientific and industrial fields.This is due to their fast growth in non-arable lands with high photosynthetic activity, theirmetabolic plasticity, as well as theirhigh CO2 capture capacity. Tetraselmis species, green and eukaryotic microalgae, are not onlyconsidered as a valuable source of biomolecules including pigments, lipids, and starch but also widely used in biotechnological applications. Tetraselmis cultivation for high-value biomolecules and industrial use was demonstrated to be a non-cost-effective strategy because of its low demand in nutrients, such as phosphorus and nitrogen. Recently, phycoremediation of wastewater rich in nutrients, chemicals, and heavy metals has become an efficient and economic-alternative that allows the detoxification of waters and inducesmechanisms in algal cells for biomolecules rich-energy synthesis to regulate their metabolic pathways. This review aims to shed light on Tetraselmis species for their different culture conditions and metabolites bioaccumulation, as well as their human health and environmental applications. Additionally, phycoremediation of contaminants associated to biofuel production in Tetraselmis cells and their different intracellular and extracellular mechanismshave also been investigated.

Electrocatalytic Performance of 2D Monolayer WSeTe Janus Transition Metal Dichalcogenide for Highly Efficient H2 Evolution Reaction.

Nowadays, the development of clean and green energy sources is the priority interest of research due to increasing global energy demand and extensive usage of fossil fuels, which create pollutants. Hydrogen has the highest energy density by weight among all chemical fuels. For the commercial-scale production of hydrogen, water electrolysis is the best method, which requires an efficient, cost-effective, and earth-abundant electrocatalyst. Recent studies have shown that the 2D Janus transition metal dichalcogenides (JTMDs) are promising materials for use as electrocatalysts and are highly effective for electrocatalytic H2 evolution reaction (HER). Here, we report a 2D monolayer WSeTe JTMD, which is highly effective toward HER. We have studied the electronic properties of 2D monolayer WSeTe JTMD using the periodic hybrid DFT-D method, and a direct electronic band gap of 2.39 eV was obtained. We have explored the HER pathways, mechanisms, and intermediates, including various transition state (TS) structures (Volmer TS, i.e., H*-migration TS, Heyrovsky TS, and Tafel TS) using a molecular cluster model of the subject JTMD noted as W10Se9Te12. The present calculations reveal that the 2D monolayer WSeTe JTMD is a potential electrocatalyst for HER. It has the lowest energy barriers for all the TSs among other TMDs. It has been shown that the Heyrovsky energy barrier (= 8.72 kcal mol-1) in the case of the Volmer-Heyrovsky mechanism is larger than the Tafel energy barrier (= 3.27 kcal mol-1) in the Volmer-Tafel mechanism. Hence, our present study suggests that the formation of H2 is energetically more favorable via the Volmer-Tafel mechanism. This study helps to shed light on the rational design of 2D single-layer JTMD, which is highly effective toward HER, and we expect that the present work can be further extended to other JTMDs to find out the improved electrocatalytic performance.

Key Factors Affecting the Success of Construction Multi Project Management

Simultaneous management of multiple projects has become a trend in the field of energy, oil and gas construction project management over the past decade. This situation is driven by the high market demand and need for fossil fuels, which also stresses project management discipline to improve its performance and efficiency in managing multiple projects simultaneously. Nevertheless, concurrent execution of multiple construction projects often leads to stretched the project durations and cost due to suboptimal resource management, which may become a boomerang and increase project costs. The objective of this study is to identify factors and indicators that contribute to the successful management of multiple projects. Although multi-project management has been extensively studied, there is still a dearth of studies analyzing the elements that make construction multi-project management successful, particularly in the energy, oil, and gas sectors. This research is a case study of an EPCIC company that uses multi-project management and operates in the oil and gas sector. Through purposive sampling techniques, a total of 58 executives from national oil and gas contractors with significant work experience participated in this study through a questionnaire survey. The PLS-SEM approach has revealed that the positive predictor factors influencing the success/performance of multi-project management are resource allocation, teamwork quality, multi-project management competency, and project manager assignment. Flexible and intelligent resource allocation management in multi-project cycles affected by uncertainty is a critical factor.

Modelling a DC Electric Railway System and Determining the Optimal Location of Wayside Energy Storage Systems for Enhancing Energy Efficiency and Energy Management

Global demand for fossil fuels is highly increasing, necessitating energy efficiency to be enhanced in transitioning to low-carbon energy systems. Electric railways are highly efficient in reducing the transportation demand for fossil fuels as they are lightweight and their energy demand can be fed by renewable energy resources. Further, the regenerative braking energy of decelerating trains can be fed to accelerating trains and stored in onboard energy storage systems (ESSs) and stationary ESSs. It is fundamental to model electric railways accurately before investigating approaches to enhancing their energy efficiency. However, electric railways are challenging to model as they are nonlinear, resulting from the rectifier substations, overvoltage protection circuits, and the unpredictability and uncertainty of the load according to the train position. There have been few studies that have examined the ESS location’s impact on improving the energy efficiency of electric railways while using specialised simulation tools in electric railways. However, no single study exists that has studied the location impact of stationary ESSs on the energy efficiency of electric railways while the trains are supported by onboard ESSs. Given these goals and challenges, the main objective of this work is to develop a model using commercial software used by industry practitioners. Further, the energy saving is aimed to be maximised using stationary ESSs installed in optimal locations while trains are supported by onboard ESSs. The model includes trains, onboard ESSs, rail tracks, passenger stations, stationary ESSs, and traction power systems involving power lines, connectors, switches, sectioning, and isolators. In this article, a test scenario is presented comprising two trains running on a 20 km with three passenger stations and two substations. The trains and track are modelled in OpenTrack simulation software (Version 1.9) while the power system is modelled in OpenPowerNet simulation software (Version 1.11). The two simulation tools are used in the railway industry and can produce realistic results by taking into account the entire electrical network structure. A stationary ESS is added on the wayside and moved in steps of 1 km to obtain the optimal location before investigating the impact of stationary ESSs on the performance and energy management of onboard ESSs. It is found that the energy saving when installing a stationary ESS at the optimal location is 56.05%, the peak-power reduction of Substation 1 is 4.37%, and the peak-power reduction of Substation 2 is 18.67%.

The growing demand for fossil fuels and subsequent CO2 emissions prompted a search for alternate sources of energy and a reduction in CO2. Photocatalysis driven by solar light has been found as a potential research area to tackle both these problems. In this direction, SAC@MOF (Single-atom loaded MOFs) photocatalysis is an emerging field and a promising technology. The unique properties of single-atom catalysts (SACs), such as high catalytic activity and selectivity, are leveraged in these systems. Photocatalysis, focusing on the utilization of Metal-Organic Frameworks (MOFs) as platforms for creating single-atom catalysts (SACs) characterized by metal single-atoms (SAs) as their active sites, are noted for their unparalleled atomic efficiency, precisely defined active sites, and superior photocatalytic performance. The synergy between MOFs and SAs in photocatalytic systems is meticulously examined, highlighting how they collectively enhance photocatalytic efficiency. This review examines SAC@MOF development and applications in environmental and energy sectors, focusing on synthesis and stabilization methods for SACs on MOFs and also characterization techniques vital for understanding these catalysts. The potential of SAC@MOF in CO2 Photoreduction and Photocatalytic H2 evolution is highlighted, emphasizing its role in green energy technologies and advances in materials science and Photocatalysis.

Biomolecular condensates of Chlorocatechol 1,2-Dioxygenase as prototypes of enzymatic microreactors for the degradation of polycyclic aromatic hydrocarbons

Polycyclic aromatic hydrocarbons (PAHs) are molecules with two or more fused aromatic rings that occur naturally in the environment due to incomplete combustion of organic substances. However, the increased demand for fossil fuels in recent years has increased anthropogenic activity, contributing to the environmental concentration of PAHs. The enzyme chlorocatechol 1,2-dioxygenase from Pseudomonas putida (Pp 1,2-CCD) is responsible for the breakdown of the aromatic ring of catechol, making it a potential player in bioremediation strategies. Pp 1,2-CCD can tolerate a broader range of substrates, including halogenated compounds, than other dioxygenases. Here, we report the construction of a chimera protein able to form biomolecular condensates with potential application in bioremediation. The chimera protein was built by conjugating Pp 1,2-CCD to low complex domains (LCDs) derived from the DEAD-box protein Dhh1. We showed that the chimera could undergo liquid-liquid phase separation (LLPS), forming a protein-rich liquid droplet under different conditions (variable protein and PEG8000 concentrations and pH values), in which the protein maintained its structure and main biophysical properties. The condensates were active against 4-chlorocatechol, showing that the chimera droplets preserved the enzymatic activity of the native protein. Therefore, it constitutes a prototype of a microreactor with potential use in bioremediation.

Research on the assessment of technical methods to suppress auger recombination

Human demand for fossil fuels has reached a very high level. However, fossil energy stocks are limited and, more importantly, their impact on the environment is increasing. The exploration of clean energy is particularly important. Among all the clean energy sources, solar energy is a very promising and important alternative to fossil fuels. And one of the primary reasons for the failure of solar photovoltaic cells to achieve rapid development is the generation of Auger composite. In order to provide support to solve this problem or facilitate the follow-up of researchers, this paper summarizes several effective methods such as Interfacial Engineering and Gradient Alloying to solve the Auger recombination problem in multi-exciton photovoltaic cells through reading and comparing a large number of relevant authoritative literature. The two methods mentioned above suppress Auger recombination by applying a new type of MXene (Nb2CTX-MXene) to the interface of SnO2 layers to pssivate the interfacial defects and promote charge transport and to generate InAs/CdSe core/shell QDs, overcoating InAs QDs with a lattice-matched CdSe shell. Comparing a large number of pieces of literature, it is found that the above two methods have guiding effects in improving the efficiency of photovoltaic cells.

Integration of Seismic and Well Log Data for Reservoir Characterization in Offshore Niger Delta, Nigeria

The demand for fossil fuels is continually increasing due to the growing global population and industrialization. It is thus necessary to find hydrocarbon prospects in new fields and those that have previously been classified as marginal fields in order to maximize production. An integrated approach is required to effectively characterize hydrocarbon reservoirs and assess their ability to store and produce hydrocarbons. 3D seismic reflection data and well log data were combined to quantitatively estimate hydrocarbon reserves in a field, offshore Niger delta, Nigeria. The reservoirs were delineated on the gamma ray and resistivity logs which penetrate four wells selected from the field. The petrophysical analysis provided information about the net-to-gross thickness ratio, porosity, shale volume and water saturation of the reservoirs, deduced from well log suites comprising gamma, resistivity, density and neutron-porosity logs through four wells. The seismic interpretation involved mapping of horizons and faults across the wells on the seismic section. Check shot data were used to tie the seismic data to the well log data to generate the synthetic seismogram. The time structural and depth structural maps were generated. The volumetric analysis entailed derivation of the Gross rock volume from the depth structural map, and estimation of the Stock Tank Oil Initially In Place (STOIIP). Four reservoirs were delineated in each of the four wells. The average thickness of the reservoirs ranges from 56.6 m to 232.7 m while the water saturation varies from 0.29% to 0.57%. The average porosities of the reservoirs ranges from 0.18% to 0.22%. The structural interpretation of the eight faults mapped reveals synthetic and antithetic faults, and rollover anticlines. The time- and depth structural maps generated from the mapped horizons show that the reservoirs are penetrated by the different faults. The Stock Tank Oil Initially In Place (STOIIP) of the reservoirs range from 25 MMstb to 468 MMstb. The study shows that the integration of 3D reflection data and well log data can be used effectively to estimate hydrocarbon reserves. The results of the study are expected to contribute to the development of new exploration and production strategies in the Niger delta basin and similar sedimentary environments.
