Optimizing and accelerating history matching progress of numerical reservoir simulation by using material balance analysis

In view of the problem of huge computations and multiple solutions, a method for optimizing and accelerating the progress of history matching by using material balance analysis was established. Based on simple measuring data, such as average pressure, daily production rate and PVT test, a material balance model can be constructed for a three phase system of hydrocarbon reservoir. According to the material balance calculation, original oil in place and aquifer parameters can be obtained as optimized parameters for numerical simulation, which contributes to solve the multi-solutions problem of history matching. Besides, by conducting uncertainty analysis using Monte-Carlo simulation method, one can determine the adjustment range of input parameters, which helps the engineer definite a clear direction, reduce the number of computations and consequently accelerate the progress of history matching. The reliability of the proposed method was verified according to two examples.

Aqueous Solution of Ketone Solvent for Enhanced Water Imbibition in Fractured Carbonate Reservoirs

Summary This paper presents four dynamic imbibition experiments using fractured limestone cores with aqueous solutions of 3-pentanone and a nonionic surfactant. Results of the dynamic imbibition experiments were analyzed by the material balance for components: oil, brine, and chemical (3-pentanone or surfactant). The analysis resulted in a quantitative evaluation of the imbibed fraction of the injected components (brine and chemical additives) and the relative contribution of these components to the oil displacement in the matrix. Results show that 3-pentanone and surfactant both can enhance the imbibition of brine through wettability alteration; however, 3-pentanone is more efficient in transferring from a fracture to the surrounding matrix. The imbibed fraction was more than 57.0% for 3-pentanone, and only 6.0% for surfactant at the end of the chemical-slug stage. During injection of the 3-pentanone solution, brine and 3-pentanone both displaced oil from the matrix pore volume (PV). Results of the material-balance analysis suggest that an optimal process with an aqueous wettability modifier will have a large imbibed fraction to rapidly enhance the oil displacement by brine in the matrix. Such a process will benefit from chase brine and soaking (or shut-in) so that the oil recovery can be maximized for a small amount of chemical injection.

EVALUATION OF AKPET GT9 GAS CONDENSATE RESERVOIR PERFORMANCE

To effectively evaluate a gas condensate reservoir performance, the reservoir engineer must have a reasonable amount of knowledge about the reservoir to adequately analyze the reservoir performance and predict future production under various modes of operation. Due to the multiphase flow that exists in the reservoir, characterization of gas condensate reservoirs is often a difficult task with the variation of its overall composition in both space and time during production which complicates well deliverability analysis and the sizing of surface facilities. This study is primarily concern with the evaluation of a gas condensate reservoir performance of Akpet GT 9 Reservoir in the Niger Delta region of Nigeria with material balance analysis tool “MBal” without having to run numerical simulations. The result obtained with MBal on the analysis of Akpet GT 9 reservoir gave 23.934 Bscf of gas initially in place which compares favorably with the volume obtained from volumetric techniques. Results also shows that the most likely aquifer model is the Hurst–Van Everdingen - Dake radial aquifer and the reservoir is supported by a combined drive of water influx and fluid expansion.

Modern Rate Transient Analysis (RTA) is the hottest technology in recent years in reservoir engineering. Its main working principle is combining production data with bottom-hole pressure data based on the assuming reservoir model and well model. It will evaluate the reserves (Oil Drainage Radius and STOIIP), reservoir properties (permeability), wellbore condition (skin) and forecast production performance for single well based on matching Blasingame and Log-Log type-curve. The RTA was found to be extremely powerful and popular particularly with high resolution to obtain equivalent results with PTA rather than limited shutting well. With benefit of continued monitoring of production and FBHP or FWHP, it is possible to evaluate the wells’ interference and boundary in distance besides conventional reservoir properties. In this paper, taking a carbonate reservoir in the Middle East as an example, this technology was applied to diagnose and analyze the abnormal production of pilot horizontal wells. Based on the analysis results, combining with the understanding of geological study, material balance analysis, numerical simulation and adjacent vertical well’s performance, it is clear that the distribution of mudstone interlayer and reservoir poor connectivity in member-A are the main interior factors of the abnormal production of pilot horizontal wells. According to the research, this paper put forwards optimization of development strategy for subsequent producing subzones, well location and well type of new well in interest area.

Use of nitrate-nitrogen concentration for controlling source, cellular matter production and oxygen consumption for sewage treatment

Carbon saving, oxygen consumption reduction and cellular matter production reduction of Modified University of Cape Town (MUCT) process under different nitrate-nitrogen concentration in the main anoxic section was studied. This was investigated by material balance analysis, biochemical reaction process and its metrology of ordinary heterotrophic bacteria, denitrifying bacteria, nitrifying bacteria and phosphorus-accumulating bacteria. The flow and distribution of carbon, nitrogen, and oxygen in the MUCT, and the influence of the regulation of the c(NO3) on the carbon source, cellular matter production, and oxygen consumption of the process were explained in detail. In the programmable logic controller (PLC) automatic control system, the circulating flow rate of nitrate was set as the controlled variable. Adopting the feedback control structure, c(NO3) was altered at 0.5, 1.0, 1.5, 2.0, 2.5, 3.0, 3.5 and 4.0 mg·17−1, respectively. In this experimental study, the quality of influent and other operation design parameters remained unchanged. The results showed that the effluent quality was at its best when c(NO3) was controlled at 2.0–4.0 mg/L. Again, the distribution of chemical oxygen demand (COD) in the anaerobic section was between phosphorus-accumulating bacteria, common heterotrophic bacteria and denitrifying bacteria, and the distribution was related to c(NO3). Due to this phenomenon, the distribution of nitrate-nitrogen between denitrifying bacteria and denitrifying phosphorus-accumulating bacteria, and poly-hydroxy alkanoates (PHA) between denitrifying phosphorus-accumulating bacteria and aerobic phosphorus-accumulating bacteria was changed. Carbon source of 110.0 kg acetic acid/103 m3 sewage was saved, while the cell material output was reduced by 37.5%, and the oxygen consumption of 51.1 kg O2/103 m3 sewage was reduced. In the MUCT process, the regulation of c(NO3) enhanced the denitrifying phosphorus uptake performance of the main anoxic section and obtained good carbon source savings, reduction of cellular matter production, and reduction of oxygen consumption.

Enrichment of Denitrifying Bacterial Community Using Nitrite as an Electron Acceptor for Nitrogen Removal from Wastewater

This work aimed to enrich a denitrifying bacterial community for economical denitrification via nitrite to provide the basic objects for enhancing nitrogen removal from wastewater. A sequencing batch reactor (SBR) with continuous nitrite and acetate feeding was operated by reasonably adjusting the supply rate based on the reaction rate, and at a temperature of 20 ± 2 °C, pH of 7.5 ± 0.2, and dissolved oxygen (DO) of 0 mg/L. The results revealed that the expected nitrite concentration can be achieved during the whole anoxic reaction period. The nitrite denitrification rate of nitrogen removal from synthetic wastewater gradually increased from approximately 10 mg/(L h) to 275.35 mg/(L h) over 12 days (the specific rate increased from 3.83 mg/(g h) to 51.80 mg/(g h)). Correspondingly, the chemical oxygen demand/nitrogen (COD/N) ratio of reaction decreased from 7.9 to 2.7. Both nitrite and nitrate can be used as electron acceptors for denitrification. The mechanism of this operational mode was determined via material balance analysis of substrates in a typical cycle. High-throughput sequencing showed that the main bacterial community was related to denitrification, which accounted for 84.26% in the cultivated sludge, and was significantly higher than the 2.16% in the seed sludge.

A simple NMR methodology for evaluating filter cake properties and drilling fluid-induced formation damage

An efficient drilling fluid will form a filter cake that will minimize the drilling fluid invasion into any drilled formation. Drilling fluid must therefore be adequately evaluated in the laboratory prior to field trial. Filter cake properties such as thickness, porosity, permeability, and pore structure are frequently evaluated using several techniques such as CT scan, SEM, and XRF. However, each of these techniques can evaluate only one or two filter cake properties. This paper presents a simple but novel NMR technique to evaluate filter cake properties such as thickness, pore volume, porosity, and possibly permeability. Furthermore, the amount and particle size distribution of solids that invaded a given rock sample can be obtained using the same technique. The full procedure was tested and verified using four identical rock samples. Drilling fluid invasion and filter cake deposition experiments were conducted on each of the samples, using the same drilling fluid but four different concentrations of fluid loss additive. NMR T2 relaxation measurements were taken at three different stages of each rock sample: before filter cake deposition; after fluid invasion and filter cake deposition; and after filter cake removal. A material balance analysis of the probability density function and cumulative distribution function of the measured T2 profile at the different stages of each sample yielded multiple filtration loss properties of the filter cake. The results obtained showed high accuracy of the NMR versus the current techniques. Moreover, this current method evaluated the majority of the filter cake properties at the same time and in situ hence eliminated the need of using multi-procedures that disturb the sample state. Finally, the presented method can also be used to evaluate secondary damage associated with filter cake removal process.

Application of Hydrodynamic Potential Analysis to Investigate Possibility Reservoir Connectivity between Neighboring Gas Fields

T field is a producting gas field in North Bali PSC, which currently producing 210 mmscfd from paciran sand stone formation. Paciran formation extends more than 20 km across the PSC area, which consists of 3 developed gas fields and one potential development field. The flowing material balance analysis conducted on T field suggests possibility of reservoir connectivty between this field and its neighboring fields. Even though each field is already have a well defined Gas Water Contact, a thorough investigation was done using hyrdodynamic potential analysis to see if theres any hydrodynamic potential that allowed connectivity between these fields, and enable tilted contact occurred between these field. Using pressure data taken from each fields exploration wells the analysis can be conducted that conclude that there is an existing hydrodynamic potential between gas fields in paciran formation. A review on the tilted contact analysis concludes that the existing hydrodynamic potential is not enough to tilt the contact as per actually observed contact.

Combining Autoclaving with Mild Alkaline Solution as a Pretreatment Technique to Enhance Glucose Recovery from the Invasive Weed Chloris barbata.

Developing an optimum pretreatment condition to enhance glucose recovery assessed the potential of Chloris barbata, which is a common invasive weed in Thailand, as a feedstock for bioethanol production. Chloris barbata was exposed to autoclave-assisted alkaline pretreatment by using different sodium hydroxide (NaOH) concentrations (1% to 4%) and heat intensities (110 °C to 130 °C) that were dissipated from autoclaving. The optimum condition for pretreatment was determined to be 2% NaOH at 110 °C for 60 min. At this condition, maximum hydrolysis efficiency (90.0%) and glucose recovery (30.7%), as compared to those of raw C. barbata (15.15% and 6.20%, respectively), were observed. Evaluation of glucose production from 1000 g of C. barbata based on material balance analysis revealed an estimated yield of 304 g after pretreatment at the optimum condition when compared to that of raw C. barbata (61 g), an increase of five-fold. Structural analysis by the scanning electron microscopy (SEM) and X-ray diffraction (XRD) revealed the disruption of the intact structure of C. barbata and an increase in the cellulose crystallinity index (CrI), respectively. The results from this study demonstrate the efficiency of using C. barbata as a potential feedstock for bioethanol production.

Effects of Rate, Temperature, and Solvent Type on Vapor/Oil Gravity Drainage (VOGD) in Fractured Reservoirs

Summary Application of thermal and solvent enhanced-oil-recovery (EOR) technologies for viscous heavy-oil recovery in naturally fractured reservoirs is generally challenging because of low permeability, unfavorable wettability and mobility, and considerable heat losses. Vapor/oil gravity drainage (VOGD) is a modified solvent-only injection technology, targeted at improving viscous oil recovery in fractured reservoirs. It uses high fluid conductivity in vertical fractures to rapidly establish a large solvent/oil contact area and eliminates the need for massive energy and water inputs, compared with thermal processes, by operating at significantly lower temperatures with no water requirement. An investigation of the effects of solvent-injection rate, temperature, and solvent type [n-butane and dichloromethane (DCM)] on the recovery profile was performed on a single-fracture core model. This work combines the knowledge obtained from experimental investigation and analytical modeling using the Butler correlation (Das and Butler 1999) with validated fluid-property models to understand the relative importance of various recovery mechanisms behind VOGD—namely, molecular diffusion, asphaltene precipitation and deposition, capillarity, and viscosity reduction. Experimental and analytical model studies indicated that molecular diffusion, convective dispersion, viscosity reduction by means of solvent dissolution, and gravity drainage are dominant phenomena in the recovery process. Material-balance analysis indicated limited asphaltene precipitation. High fluid transmissibility in the fracture along with gravity drainage led to early solvent breakthroughs and oil recoveries as high as 75% of original oil in place (OOIP). Injecting butane at a higher rate and operating temperature enhanced the solvent-vapor rate inside the core, leading to the highest ultimate recovery. Increasing the operating temperature alone did not improve ultimate recovery because of decreased solvent solubility in the oil. Although with DCM, lower asphaltene precipitation should maximize the oil-recovery rate, its higher solvent (vapor)/oil interfacial tension (IFT) resulted in lower ultimate recovery than butane. Ideal density and nonideal double-log viscosity-mixing rules along with molecular diffusivity as a power function of oil viscosity were used to obtain an accurate physical description of the fluids for modeling solvent/oil behavior. With critical phenomena such as capillarity and asphaltene precipitation missing, the Butler analytical model underpredicts recovery rates by as much as 70%.

The effects of main anoxic section oxidation-reduction potential on the metabolism of PHA and TP in continuous-flow single-sludge treatment system

The experimental results and material balance analysis in this paper revealed the regularity of poly-hydroxy alkanoates (PHA) and total phosphorus (TP) metabolism in a continuous-flow single-sludge wastewater treatment system under different main anoxic section oxidation-reduction potential (ORPan) conditions. We also evaluated the effectiveness of the operation control parameters of ORPan as the continuous-flow single-sludge sewage treatment system from the aspect of the reaction mechanism. Using a programmable logic controller (PLC) automatic control system to take the circulating flow in nitrification as the controlled variable based on the feedback control structure, an experimental study was carried out under the condition of ORPan setting value of −143mV, −123mV, −105mV, −95mV, −72 mV and −57mV, respectively, with other operational design parameters remaining unchanged. Influent water quality of chemical oxygen demand/total nitrogen (COD/TN) was 5.0±0.6. The results showed that when ORPan was set at −95mV, the maximum values of PHA synthesis and storage rate, PHA degradation rate, phosphorus release rate and phosphorus absorption rate in anaerobic and pre-anoxic segments were 82.34, 7.90, 47.31, 14.27, 1.50 and 8.52mg/ (L·h), respectively. According to the metabolic mechanism of PHA and TP, ORPan was further proved to be the operation control parameter of the continuous-flow single-sludge sewage treatment system, and when the COD/TN value was 5.0±0.6, the optimal setting value was −95mV.

Xylitol Production from Lignocellulosic Pentosans: A Rational Strain Engineering Approach toward a Multiproduct Biorefinery.

Kluyveromyces marxianus IIPE453 can utilize biomass-derived fermentable sugars for xylitol and ethanol fermentation. In this study, the xylitol production in the native strain was improved by overexpression of endogenous d-xylose reductase gene. A suitable expression cassette harboring the gene of interest was constructed and incorporated in the native yeast. qPCR analysis demonstrated the 2.1-fold enhancement in d-xylose reductase transcript levels in the modified strain with 1.62-fold enhancement in overall xylitol yield without affecting its ethanol fermenting capacity. Material balance analysis on 2 kg of sugar cane bagasse-derived fermentable sugars illustrated an excess of 58.62 ± 0.15 g of xylitol production by transformed strain in comparison to the wild variety with similar ethanol yield. The modified strain can be suitably used as a single biocatalyst for multiproduct biorefinery application.

Optimization of operational techniques in waste management case study: Lhokseumawe City

The high volume of waste that is not followed by properly waste management method, makes the waste management in Lhokseumawe not optimal. This problem is shown by the level of waste service is only about 38 %, while the waste that is not transported will be cumulative in any places. This is showed that the level of waste service is below of the minimum service standard that is 60 %–90 %. It is necessary to improve the waste management, especially in the utilization of waste to reduce the waste and landfill load. This research aims to evaluated and analysis of waste management in Lhokseumawe by two waste reduction scenarios, that are waste bank scenario and recycle scenario. The method that were used in this research are material balance analysis, lifetime of landfill, and cost analysis. The result showed that waste reduction by scenario 1 and scenario 2 can reduce of waste in landfill about 49.8 % and 51.02 %. The lifetime of landfill by the waste reduction can be used for 28 years from the lifetime 18 years. Investment cost estimated that required in scenario 1 and scenario 2 are smaller than the investment cost of existing, respectively IDR746,646,860, IDR755,530,822 and IDR1,202,644,444.

Hydrocarbon-Gas Cycling Improves Recovery in the Arun Gas Field

This article, written by JPT Technology Editor Chris Carpenter, contains highlights of paper SPE 186280, “Review of 20 Years of Hydrocarbon-Gas Cycling in the Arun Gas Field,” by Suhendro, SPE, Pertamina Hulu Energi, prepared for the 2017 SPE/IATMI Asia Pacific Oil and Gas Conference and Exhibition, Bali, Indonesia, 17–19 October. The paper has not been peer reviewed. Lean-gas injection has been used as an alternative method in gas fields to maintain reservoir pressure, minimize condensate banking near the wellbore, and mitigate oversupply operations during low-market periods. In this paper, past gas-cycling operations were examined to identify subsurface implications and effects on operability aspects for the Arun giant gas field offshore Indonesia in the North Sumatra Basin. Production and pressure data show that gas cycling contributes significantly to the improvement of field-recovery factors. Reservoir and Fluid Description The Arun gas field was discovered in 1971. The formation is carbonate reef, created during the Miocene age. It lies between two thick shale layers, Bampo on the bottom and Baong on the top. The Bampo formation is identified as source rock, with Baong shale as caprock. The field trends north to south, with a width of 18.5 km and a length of 5 km. Gas/water contact, to the south and west, was tilted toward the southern part of the field. A gas-condensate reservoir at a depth of 10,000 ft was found to have an average thickness of 503 ft and an area of 21,450 acres, with 7,100-psig initial pressure and a temperature of 352°F. Initial condensate/gas ratio (CGR) was 50 bbl/MMcf. The reservoir has 16.2% average porosity and 17% initial water saturation. Volumetric original gas in place (OGIP) is calculated to be 17 scf. The current production rate from the field is approximately 80 MMcf/D with 2,400 bbl of condensate/day. Fluid expansion and gas injection are determined to be the two main drive mechanisms on the basis of material-balance analysis. Hydrocarbon production uses four clusters with approximately 21 wells in each cluster. Each cluster is equipped with the same typical surface facilities. All produced fluid is pooled at Point A before being piped to gas-processing facilities. Initially, the produced gas was delivered to the Arun liquefied natural gas (LNG) plant for liquefaction but, in late 2014, the plant was shut down because of contract termination. In the second quarter of 2015, the facilities were reactivated for an LNG regasification terminal, Perta Arun Gas (PAG). Currently, the produced gas is transported to PAG for separation and dehydration before downstream processing. The northern part of the field contains fair porosity; the middle part is dominated by good and fair porosity, while the southern part has a greater incidence of poor porosity. Clusters II and III, which are located at the middle part, contribute more cumulative gas production and condensate compared with Clusters I and IV. Thus, better reservoir properties and parameters are contributing to better production.

Geological Life Cycle Inventory Model Development for Shale Gas Resources

This paper presents an innovative life cycle assessment approach for shale gas production, which integrates geological system characteristics with a surface emission model to estimate the overall GHG emissions. Firstly, the model developed incorporates a Volumetric Estimation technique, Flowing Material Balance and Advance Decline Curve analysis to estimate the field gas in-place and estimated ultimate resource (EUR). Next, this geological model is integrated with the surface emission model, which is based on engineering design and operational parameters, to estimate the GHG as well as other emissions (direct and indirect; gaseous, liquid, solid waste) and resource use (materials, energy, water) from site construction, drilling, hydraulic fracturing, well completion, well head operations, gas gathering and gas processing. The cradle to gate LCA model developed was applied to the Fayetteville shale gas field using public domain data. Three possible field development strategies were developed and implemented in the life cycle inventory model developed. They all comply with the outputs of the subsurface constraint inventory model but differ in terms of selected parameters in well construction, well drilling, hydraulic fracturing, well completion, well head and surface facilities operations. The annual GHG emissions of Fayetteville shale gas field production with a sensitivity analysis was estimated for the three different field development strategies. The resulting life cycle GHG emissions range between 12.79 and 21.09 CO2 equivalents per Mscf of gas produced or 13.65 to 22.51 CO2 equivalents per MJ of gas produced. The water consumption is estimated in the range of 18 litres of water per Mscf of gas production.

Exergetic analysis and pollutants emission from a rotary kiln system in a major cement manufacturing plant

The exergy analysis and air pollutants emission estimation from the kiln system of a major cement manufacturing plant located in Nigeria were conducted with a view to improve the level of performance of the production unit and minimize environmental effects. Material balance and exergy analysis were carried out on the system to determine the exergetic efficiency and exergy destruction rate. Pollutants emission was estimated using bottom-up emission factor approach. The physical and chemical exergy output obtained were 9.07×107 and 1.46×08 kJ/h, respectively. The exergy efficiency of the kiln system was 27.35%. The measure of entropy generation (6.53×108 kJ/h) represented a huge potential for energy savings for the unit. CO2 emission represented about 99.04% of the total criteria air pollutants emission from the kiln and an estimate of 0.90 tonnes of CO2/tonne of clinker produced was obtained. To improve the exergy efficiency and reduce pollutants emission from the kiln system, possible heat recovery options and CO2 mitigation approaches were suggested.

Pyrolysis of methyl ricinoleate by microwave-assisted heating coupled with atomization feeding

A stable high-temperature reaction site and the uniformity and speed of heating the feedstocks play a key role in pyrolysis processes. In this study, microwave-assisted heating coupled with atomization feeding was used to pyrolyze methyl ricinoleate (MR) for the efficient, continuous production of undecylenic acid methyl ester (UAME) and heptanal (HEP). The effects of feed mode, reaction temperature and preheating temperature on microwave-assisted pyrolysis (MAP) were examined. The maximum selectivities of HEP and UAME could reach 91.4 wt.% and 76.6 wt.%, respectively, at the reaction and preheating temperatures of 500 °C and 150 °C, respectively, using atomization feeding. The gas, liquid and solid products were determined by gas chromatography (GC), GC-mass spectrometry (MS) and Fourier transform infrared (FT-IR), and the gas, liquid and solid yield reached 7.0 wt.%, 89.0 wt.% and 0.1% wt.%, respectively, with an error of 3.9 wt.% at 500 °C. The pyrolysis of MR via microwave-assisted heating coupled with atomization feeding was found to be more efficient than the conventional pyrolysis process. In addition, the theoretical and actual heat for MAP of MR was 1461 kJ/kg and 2629 kJ/kg at 500 °C, respectively. The material balance and heat analysis results can be used to guide the design of an amplifying device.

New environmentally attractive separation technology for flue gas mixture

ABSTRACTSeparation of gaseous mixtures produced from any process plant can be a major issue for the industry. In comparison to other separation techniques available, hydrate formation can be an appropriate choice in terms of fuel efficiency and degree of separation. In this work, a three-stage process was designed to capture CO2 from a hypothetical flue gas mixture (comprising 15 mol% CO2 + 85 mol% N2). For the hydrate based CO2 capture process, a detailed analysis was carried out covering the material and energy balance, energy integration and economic analysis. The results show that, at steady state, 91% of the CO2 in the flue gas can be recovered, resulting into two streams: Stream-A (94 mol% CO2 + 6 mol% N2) and Stream-B (1.5 mol% CO2 + 98.5 mol% N2). Per 100 mol of the flue gas feed, 3.9 MW of energy is required to achieve such degree of separation. This amount was reduced to 2.4 MW after energy integration was applied to the process. Overall, the process can help in reducing CO2 emission via flue gas because of the huge difference in the carbon foot print of its energy requirement (500 g CO2 per kWh) and the amount of CO2 captured by the process (2190 g CO2 per kWh).

Green productivity improvement and sustainability assessment of the motorcycle tire production process: A case study

Abstract This paper addresses the result of a case study applying green productivity and sustainability assessment to the motorcycle tire production process. The main objective of this study was to obtain a potential productivity improvement scenario and, at the same time, perform a sustainability assessment of motorcycle tire production. The study was conducted by combining a green productivity analysis with a material balance and green value stream analysis, a sustainability assessment with multidimensional scaling and a fuzzy analytical hierarchy process (AHP), which generated possible scenarios and suggested the best potential scenario. The green productivity analysis showed that the level of productivity was higher than the environmental impact in the production process. Meanwhile, based on the sustainability assessment, the economic, environmental, and social dimensions clearly affect the sustainability. The economic dimension is considered less sustainable, while the environment and social dimensions are quite sustainable. The green productivity index is useful in highlighting the eco-efficiency indicators. The best scenario suggested to improve the productivity of motorcycle tires was a combined treatment of controlling raw material characteristics and reusing water and materials. Implementation of the best scenario would increase the green productivity index from 1.081 to 1.123. The results show that applying the best scenario could improve the performance of the motorcycle tire production process.
