Implementation of a New Proprietary Vortex Fluid Sucker Rod Pump System to Improve Production by Enhancing Flow Dynamics

Summary Conventional ball valve systems and insert-guided cages compromise performance due to gas interference, solids accumulation, and ball vibration that shortens the life and efficiency of conventional traveling and standing valve cages. The analysis of the flow profile around a common ball valve resulted in the design of a new proprietary pump system that maximizes fluid flow, creating a vortex profile that extends service life while increasing production. The proprietary vortex fluid pump system was compared against conventional inserts during in-house testing and in a laboratory flow loop. Minimum to maximum flow rates were digitally measured to calculate the pressure drop at each flow rate with and without injecting gas. The transparent flow loop tubing allowed a visual qualitative assessment of fluid flow. During laboratory testing, conventional inserts measured high ball vibration with excessive pressure drop. The proprietary vortex fluid pump system had no ball vibration, with a significant pressure drop decrease, and gas remained entrained as it cycled through a vortex flow. The results from laboratory testing showed an average 40–46% pressure drop decrease compared to conventional inserts. Laboratory data were confirmed in numerous field applications as well as four case studies from four different fields for four separate operators. The vortex fluid pump system showed greater pump efficiencies and pump longevity. After installation of the system, cumulative results were combined to show an average 46% production increase over 485 wells in North America in 1 year. The proprietary vortex fluid pump system decreases erratic velocity profile and reduces vibration in the valve system resulting in improved efficiency and reliability of sucker rod pumps. The design optimizes flow dynamics enabling the ball to remain stationary, allowing smaller and lighter balls and increasing the cross-sectional flow area in the most restrictive pump section. The design reduces solids accumulation, lessens cage wear, improves pump efficiency, and increases production. The vortex fluid pump system replaces all conventional valve systems.

Field hydrothermal identification with groundwater flow by conducting Distributed Thermal Response Test (DTRT) through Moving Line Source (MLS) theory

Thermal Response Test (TRT) is conventionally used to get the ground thermal properties by using Infinite Line Source (ILS) method. However, ILS method gets abnormally ground thermal conductivity when there is an apparent groundwater flow. Moreover, traditional TRT is not able to identify the ground thermal properties along the vertical profile, misleading the hydrogeological engineering applications. In this investigation, ILS and Moving Line Source (MLS) models considering the variation of time were adopted to estimate the ground hydrothermal properties along a heat exchanger with different heating loads by Distributed Thermal Response Test (DTRT). The results showed that carrying fluid temperature gradient varies in different layers, attributed to the variation of ground hydrothermal properties. Thermal conductivity is overestimated by ILS for layers with groundwater flow, while MLS estimates more realistic values. Specifically, thermal conductivity, ground thermal resistance obtained by ILS method can be respectively 2240 %, 66.7 % higher than the values obtained by MLS method, for the layer with apparent groundwater flow. The groundwater velocity was generally underestimated by MLS, and a parameter was adopted to get the real Darcy velocity. In addition, the heat load influences the TRT results, especially when there are boundary effects or the presence of groundwater flow. A higher heat load leads to more reliable ground hydrothermal properties, and it is recommended that the heat injection rate remains between 30 and 70 W.m−1. Test time is also important in TRT, and a test duration longer than 30 h is recommended to reach stable ground hydrothermal properties illustrated by ILS and MLS methods. The investigation is helpful to give guidance for the design of Ground Source Heat Pump (GSHP) systems, especially for the stratified ground with apparent groundwater flow.

The first paper selected for this Intelligent Fields Technical Focus presents the use of a unique artificial-intelligence (AI) technique from the fourth industrial revolution—dual heuristic dynamic programming—to address business opportunities associated with optimization. The background, methodology, and novelty presented by the authors are clear; however, they need to benchmark their efforts and claims of improvement with peers. The second paper demonstrates well-structured content, though the topic is detailed, with the introduction of a digital laboratory called Ibtikar toward the enablement of connecting to open-source tools with the use of AI. The collaboration in research and development, as well as addressing challenges of upstream oil and gas requirements, is commendable. The authors, however, do not address associated security concerns concerning the open-source aspect of the technology. The third paper presents a combination of technologies used to automate daily data acquisition and model updates from production databases and run a supervised machine-learning model to continuously calibrate the network model.

An investigation on the efficient reverse cycle defrosting strategy for microchannel heat exchanger heat pump system

Microchannel heat exchangers (MCHX) are widely used in heat pump systems due to their high efficiency and lower refrigerant charge. However, during the defrosting processes, the MCHX heat pump system encounters some problems, such as longer defrosting duration and lower defrosting efficiency due to its poor drainage performance. To solve these problems, a new defrosting control strategy with indoor fan and electric heater turned on at the same time was proposed in this study. The defrosting characteristics of the new defrosting strategy and the conventional defrosting strategy were compared experimentally. Results indicate that the new defrosting strategy could shorten the defrosting time by 59.4% at Tamb = 2 °C and 65.9% at Tamb = −5 °C. Meanwhile, the defrosting efficiency of the new defrosting strategy was improved by 14.2% at Tamb = 2 °C and 18.0% at Tamb = −5 °C. In addition, as the relative humidity decreased, both defrosting duration and defrosting energy consumption would be reduced under different defrosting strategies, and it was more advantageous for conventional defrosting strategy. Due to the reduction of defrosting duration, the heating capacity of the heat pump system would increase during the periodic defrosting and defrosting cycles. In this study, the average heating capacity of the heat pump system with the new defrosting strategy was increased by 14.2% at Tamb = 2 °C and 18.0% at Tamb = −5 °C. Furthermore, for the conventional defrosting strategy, wet compression occurred in the late defrosting stage, which could significantly affect the reliability of the compressor. For the new defrosting strategy, wet compression was eliminated during defrosting due to the better heat transfer in the indoor coil, which was a reliable way for system operation. The contribution of this study can effectively guide the defrosting strategy design of MCHX heat pump system, improve the thermal comfort of occupants and promote the heat pump system energy saving.

Techno-economic analysis of utilizing a directly-coupled photovoltaic water pumping system for domestic application in Nigeria

This paper presents a techno-economic application of a directly-coupled PV-pumping system for domestic application in some selected rural communities in Nigeria. Four different rural communities were considered in Ogun State, Nigeria and data of volume of water requirement per household per day were obtained through the use of interview scheduled for the rural households. The system is properly sized such that the pump energy requirement is in tandem with the PV-system of the location. Six different submersible pumps of different ratings were considered for this study. The number of PV-arrays, controllers and the tank storage capacities for various pumps were also determined. MATLAB tool is used to simulate the system. The economic assessment of the system, which includes life cycle cost, energy cost of pumps and the cubic meter cost of water were also determined. The result reveals that the life cycle cost ranges from unit cost of energy ranges from unit cost of water per cubic meter ranges from for the various submersible pumps considered. The maximum power and voltage and the efficiency of the PV module selected for the analysis are 250 W, 24 V and 14%. Also, the result also reveals that the proposed system is more cost effective than the conventional public utility water cooperation in Nigeria. The study provides the design and simulation of PV-based water pumping system, which can be used for understanding planning water supply system for rural areas.

Testing and analysis of corrected specific frictional resistance in the ground heat exchanger with water as heat-transfer fluid

As the scale of a ground-coupled heat pump system increases, the proportion of energy consumed by the conveying system increases. It is crucial to obtain an accurate specific frictional resistance in the ground heat exchanger (GHE) to facilitate a more accurate design; this has the potential to reduce the energy consumption on the source side and improve the efficiency of the ground-coupled heat pump system. This study investigates the relationship between velocity, temperature, and pressure drop in a double U-shaped GHE with water as the heat-transfer fluid to obtain the corrected specific frictional resistance (CSFR). The test results showed that the ratio of standard specific frictional resistance (SSFR) to measured specific frictional resistance (MSFR) was greater than 1.2. The MSFR was used to fit and validate the CSFR formula, so as to determine the relationship between the CSFR and the four variables, which were density, dynamic viscosity, velocity, and inner diameter. The design based on the CSFR improved the system coefficient of performance by 7.61% compared to the SSFR design option. Therefore, use of the CSFR formula to calculate the pressure drop in the GHE groups facilitates more accurate and refined design of ground-coupled heat pump systems.

Modeling and techno-economic comparison of two types of coaxial with double U-tube ground heat exchangers

Among different types of ground heat exchangers (GHEs), multi-external chamber coaxial GHE is recently a promising design due to its geometrical characteristics of concentric tube-in-tube configuration and maximal heat exchange performance. Nevertheless, the characterization and commercialization of multi-external chamber coaxial GHEs need a deep understanding of the effect of different opt-geometrical and operational parameters on their thermo-economic performance. Therefore, accurate numerical modeling of the transient heat transfer proficiencies and the techno-economic feasibility of the multi-external chamber coaxial GHE and coaxial GHE compared to conventional double U-tube GHE is crucial to promise an optimal design of ground-coupled heat pump systems. This study introduces a comprehensive systematic and techno-economic analysis of the transient heat transfer characteristics of coaxial and multi-external-chamber coaxial GHEs compared to conventional double U-tube GHE. A three-dimensional numerical model was adopted and validated by field experiments. Moreover, a sensitivity analysis was conducted to investigate the impacts of several key operating and design parameters on heat transfer performance under heating and cooling modes conditions. Furthermore, various case studies, along with a comprehensive analysis of multi-objective optimization for minimization of the GHE number and energy consumption, were also carried out. In addition, a techno-economic analysis was also carried out using the total annual cost method to assess the economic viability of the proposed GHE designs. The results reveal that, compared to double U-tube GHE, coaxial GHE has the best thermal performance with maximum and average heat transfer rates of 127.54% and 17.67%, while the multi-external-chamber coaxial GHE is estimated to be 62.38% and 11.72%, respectively. Also, the corresponding total thermal resistance of coaxial GHE is the lowest by 14.86%, and for multi-external-chamber coaxial, it is 10.30%; also coaxial GHE has the lowest pressure drop by 76.45%, followed by multi-external-chamber coaxial GHE with 57.18%. In the case studies, replacing double U-tube GHE with coaxial or multi-external-chamber coaxial GHEs, the GHE number can be decreased by 13.3% for both the designs, or the energy consumption of the water pump by 33.91% and 30.97%, and the energy consumption of the entire system by 17.21% and 10.54%, respectively. The techno-economic analysis results indicate that replacing double U-tube GHE with coaxial GHE is the most feasible alternative, which can decrease the total annual cost by 13.58%, followed by multi-external-chamber coaxial GHE by 6.77%. Further discussion for the deep applications was performed, which concluded the optimal GHE design. The findings of this paper can be used as a guide for future research on GHEs for potential applications of ground-coupled heat pump systems.

Effect of seepage condition in geological stratification on thermal response test analysis of borehole heat exchanger

Determination of ground thermal properties is the prerequisites for the design of ground-coupled heat pump systems (GCHPs), and it is crucial for evaluating the thermal performance of borehole heat exchangers (BHEs). These parameters are usually obtained by in-situ thermal response test (TRT) based on infinite line source model (ILSM). Though the effect of the groundwater flow on the estimation of ground thermal parameters is considered in homogenous ILSM, the estimated deviation can be enlarged as seepage condition varies based on the BHE model in practical geological stratification. Based on the developed numerical layered seepage BHE model (NLSBM), this paper evaluates the effects of seepage location and seepage velocity on estimated accuracy of borehole thermal resistance and ground thermal conductivity. Relative error (RE) between effective thermal conductivity λeff and the thickness-weighted thermal conductivity λTW will be up to 30.5% with the increase of the thickness of the seepage layer. The relative error between λeff and λTW increases from 5.3% to 93.5% when seepage velocity changes from 1 × 10−6 m/s to 1 × 10−4 m/s. The minimum RE between borehole thermal resistance Rb,NLSBM and effective borehole thermal resistance Rb,eff is still up to 37% when seepage locates in the 5th layer. With the increase of the seepage velocity, the RE between Rb,eff and Rb,NLSBM is enlarged, and the minimum RE is up to 29.4% corresponding to the lowest seepage velocity of 1 × 10−4 m/s. The change of seepage velocity or seepage location has little effect on Rb,NLSBM, and the highest RE is only 0.2%.

Multicriteria Design and Operation Optimization of a Solar-Assisted Geothermal Heat Pump System

This work focuses on the determination of the design and operation parameters of a thermal system depending on the optimization objective set. Its main objective and contribution concern the proposal of a generalized methodological structure involving multiobjective optimization techniques aimed at providing a solution to a practical problem, such as the design and dimensioning of a solar thermal system. The analysis is based on system operation data provided by a dynamic simulation model, leading to the development of multiple surrogate models of the thermal system. The thermal system surrogate models correlate the desired optimization objectives with thermal system design and operation parameters while additional surrogate models of the Pareto frontiers are generated. The implementation of the methodology is demonstrated through the optimal design and operation parameter dimensioning of a solar-assisted geothermal heat pump that provides domestic hot water loads of an office building. Essentially, energy consumption is optimized for a desired domestic hot water thermal load coverage. Implementation of reverse-engineering methods allows the determination of the system parameters representing the optimized criteria.

Electrically driven heartbeat effect of gallium-based liquid metal on a ratchet.

The realization of the liquid metal heartbeat effect shows better controllability under non-periodic stimuli than spontaneous oscillation or periodic stimuli. However, adjusting the liquid metal heartbeat performance, drop spreading area, and frequency, solely by the magnitude of the voltage, has great limitations. Here, we demonstrate that the eGaIn drop can beat inside graphite ring electrodes under DC voltage in alkaline solutions on ratchet substrates. These sawtooth structures provide asymmetric textures which influence liquid metal deformation during the beating of the heart. We achieved heartbeat frequencies from 2.7 to 4.8Hz, a 100% increase in the tunable frequency range compared to that on a flat surface. The oxidative spreading of the eGaIn drop on the ratchet substrate shows that the drop penetrates into the grooves of the sawtooth structure. Moreover, we investigated the physical mechanisms affecting the eGaIn heartbeat frequency and the influence on the spreading area of the eGaIn drop at various sawtooth sizes and orientations. These findings not only enhance our understanding of droplet manipulation on sawtooth-structured surfaces but also facilitate the design of microfluidic pump systems.

The Design and Installation of Solar Pumping System for Pond Aeration in the Mina Makmur Fish Cultivator Group at Desa Ringinharjo, Bantul

The fish cultivator group “Mina Makmur” manages tilapia nursery ponds. The group faced a problem, namely: the growth of fish fingerlings was not assuring, and their bodies looked weak. This phenomenon is assumed to be due to poor pool water quality, which affects the lack of oxygen. The solution given is that the fishponds require an aerator. The solar-powered aerator was a choice to minimize operational costs. This paper aimed to design and install a solar pumping system as an aerator in a fishpond. The design begins with a site survey. A water pump was selected based on survey results. The solar module was designed using the current concept. The result of the design of the solar pumping system was that it requires a DC water pump with a power of 26.4 W and a solar module with a capacity of 60 Wp. The solar module was installed in a location free of shade and as close to the pump as possible, and the pump was placed outside the pond. These designed and installed solar pumping systems were functioning correctly. The resulting water discharge was 3.03 liters/minute at an average solar irradiance of 795.46 W/m2.

Design, simulation and performance analysis of photovoltaic solar water pumping system

Abstract The solar photovoltaic system is one of the technologies which is used to pump water in rural, isolated and desert areas where electric connection to the main grid is a problem. The study area is selected because of its higher natural resources of solar radiation over the year. Thus, that encourages us to adopt this study in order to understand the effects of various operating parameters on performance behaviour, which leads to enhancing the system design. This paper aims to assess the solar water pump system’s design and estimated performance in real environmental conditions. The PVsyst has been used to design and simulate a system which allows us to analyse the operating behaviour of a photovoltaic solar water pumping system. The solar PV pumping system design is considered; the photovoltaic module has characteristics and the pumping system characteristics. The photovoltaic array losses due to temperature were estimated about −14.3% and the soiling losses represented approximately −5%. The results showed that performance losses were significant variance in the months of the summer season from May to July. Therefore, their implication on the water flow rates significantly decreases throughout the months of the summer season from May to July, respectively.

Sustainable cooling cycles by algorithmically supported design of decentral pump systems

Accounting for up to 25% of electricity consumption in industry, pump systems are significant electricity consumers. Designing pump systems is a complex process because of the multitude of parameters and their combinations (pump types, interconnection variants, various load scenarios). Moreover, decentral pumps can be integrated to reduce the required hydraulic power, which further increases the complexity. This complexity can no longer be mastered with conventional planning methods. The aim of this paper is to tackle the complexity of pump systems design using algorithm-based design methods. The design problem is formulated as a mixed-integer nonlinear optimisation program with the objective of minimising the life cycle costs. The solution involves three steps: (i) the placement of decentral pump stations to reduce the hydraulic power, (ii) the preselection of suitable pump types, and (iii) the optimisation of the selection and operation of pumps. To solve the optimisation problem, an exact off-the-shelf solver and a problem-specific heuristic solution method are used. These are compared with conventional design methods. Both the algorithm-based and the conventional design methods are applied to an industrial cooling cycle operated by BASF SE. The results show that due to decentralisation, up to 38% (248 kW) of hydraulic power can be saved. With the help of the algorithm-based design methods, savings can also be achieved with regard to the efficiency and costs: up to 21% of the life-cycle costs can be saved while increasing the net efficiency from 47.2% to 57.8%. Furthermore, the algorithm-based design methods are superior, leading to 15% (approx. 770 000 €) lower life-cycle costs compared to conventional methods. Conventional methods based on the best efficiency point or mean efficiency show the lowest level of performance. The advantages are particularly evident in system variants with a high complexity. The trade-off between investment costs and energy demand is presented transparently using a Pareto front.

In recent years, <span>solar panels have become increasingly popular for converting solar energy is converted into electrical energy. The solar panel can be utilized as part of a larger solar system that is connected to the power grid or as a stand-alone system. Every day, the world receives 84 Terawatts of energy, yet we only use about 12 Terawatts. For optimal energy conversion, the tracking mechanism will keep the solar panel perpendicular to the sun at all times. In this setup, photo resistors will be employed as sensors. A light detection system, a microprocessor, a gear motor system, and a solar panel will make up the system. When compared to solar panels without tracking equipment, our system will produce up to 40% more electricity. Improvements to the board's efficiency include the addition of a dust sensor. The dust on the board is also detected by the sensor, which activates a pump inside the tank. It uses the Arduino to pump water onto the board to clean it of dust and maintain its efficiency. There is also a water sensor. When the tank's water level falls below a certain level, the attached pump activates.</span>

In the broader discussion regarding the so-called decarbonisation pathway, the deployment of solar-assisted heat pumps is widely accepted as a preferential strategy to be pursued in the residential sector. In this respect, hybrid photovoltaic-thermal ( PVT ) technology is very interesting, since it allows designing innovative and economical viable solar-assisted heat pumps. The present paper contributes to the present-day discussion by proposing a novel solar-assisted multifunctional heat pump. The proposed system is designed to satisfy a single-family household’s heating/cooling/domestic hot water ( DHW ) requirement. In particular, the proposed system represents an advance on studies conducted in previous years and is based on the integration of innovative PVT collectors (specifically designed for the present application), storage tanks (to decouple the “ supply-side ” and the “ demand-side ”) and a customized multisource heat pump. The results of the 8-months field monitoring are presented and discussed, demonstrating that the proposed system allows enhancing the electrical and thermal efficiency of PVT collectors, maximising the heat pump’s seasonal performance, and reducing the electricity exchange with the grid. In conclusion, the proposed system represents a practical response to the need to achieve the total decarbonisation of the residential sector.

Modernization of disc laser design using ellipsoid illuminator

Solid state disk lasers have a number of advantages over lasers with a rod active element. In particular, due to efficient heat dissipation, there is no thermal deformation of the active element and its transformation from the optical point of view into a lens. That in turn improves the stability of the generated laser beam and reduces the risk to lose of resonator stability. In addition, disk lasers are able to generate high power at a compact size. However, to ensure the direction of the pump radiation on the active element, disk lasers require a complex mirror system of reflection of the pump beams, and therefore have design limitations on the introduction of pump energy into the active element. This article is dedicated to the development of the design of pumping system, which will increase the intensity of pumping the active element of the disk laser, which will increase the generated power. The article presents the original design of a disk laser with an ellipsoidal illuminator and a tiered system for pumping the active element by diode laser radiation. The results of modeling the heat dissipation from the active element to the refrigerator are presented. The estimation of the efficiency of excitation of the active element when using an ellipsoidal illuminator and the procedure for calculating the parameters of the generated laser beam are given.

Simulation of heat pump operation. problems and prospects

The article presents the calculation and modeling of heat and mass transfer that determines the operating modes of heat pumps. The physical and mathematical simulation aims at the operation of geothermal heat pumps. It is shown that numerical simulation of the main physical mechanisms affecting the efficiency of the ground heat collection are little used for practical calculations in design of heat pump systems. The use of numerical simulation results is limited by specific geographical and climatic conditions that do not allow generalizing numerical, full-scale or laboratory experiments. Especially noticeable is a lack of complete design methods of ground heat collection systems in northern regions. A promising direction of future research is identified to obtain the data on the effect of heat and moisture transfer in the soil on the performance of geothermal heat pumps.

Using mathematical model to design and sizing of pumping water system

The role of the pump in any pumping system is to provide sufficient pressure to overcome the operating pressure of the system in order to move fluid (water) at a required flow rate to the user. In this study, a mathematics model was used for design in order to provide adequate water supply to every quarter in Federal Polytechnic Mubi, Adamawa state Nigeria. According to the research, the proposed water supply requires a 1360W power pump, a 1500W inverter, and a 1500W solar panel. Because the suggested water supply is based on renewable energy, the study found that it can be used at Federal Polytechnic Mubi to increase their supply for human use. As a result, the FPM management has reduced greenhouse gas emissions.
