Flare gas is light hydrocarbon gas, by product of any petroleum industry activities, that is flared; and it could not pass into production facilities due its to low pressure. The gas flare volume frequently is significant, causing greenhouse gas emissions which gives serious environmental issue. Aims: The purpose of this research is to utilize flare gas in oil and gas fields to reduce environmental issue. Methodology and Results: Flare gas in an oil producing field is compressed to produce higher pressure gas flow, by using three one-stage Integrated Reciprocating Compressors to enter the production trunk line. The gas is flown to CO2 Removal Plant, as the gas would be gas sales. The subject field in West Java, the production wells experiences pressure decline; resulting the wellhead flowing pressure becomes low, so the gas is being flared. The gas flare recovery system is economically profitable both for purchase and rental scenarios. Renting the equipment is more profitable and has lower technical risk, because all risks is burdened to rental service provider. Conclusion, significance and impact study: Monetizing flare gas will reduce environmental issue, and it is utilized for own use or gas sales. The best Economics Scenario is rental scenario.

<em>Flare gas recovery is needed to handling gas flares in oil and gas fields. Field C production wells experience a decline as a result the gas flow pressure in the wellhead becomes low. Low pressure gas enters the LP separator then is burned as a gas flare containing CO<sub>2</sub> of 33.38 mol and GHV of 1048.9 BTU / ft3. The flare gas recovery system is applied to reduce gas flares with the integrated reciprocating compressor unit for compression at suction pressure ± 10 psig, discharge pressure ± 100 psig and total flowrate ± 1 MMSCFD. Then the CO<sub>2</sub> removal plant produces gas with a CO<sub>2</sub> content of 7.09% mol and GHV of 1314.9 BTU / ft3. During operation, requires gas fuel ranging 11 MSCFD and the actual power ranges from 36.46 HP and 39.64 BHP. Economic aspects analysis, gas flare monetization for the period of 2015 until 2022, gross reserves 2,062,917 MMBTU and gross income of US$ 6,026,744. The operating cost of the the lease purchase scheme, the government US $ 2,079,696 and the contractor US $ 1,386,464 with POT 1.7 years and IRR 151.5%.</em>

Based on the well-known results of studies of the ether-geosoliton concept of the growing Earth, the article presents the conclusions that made it possible to propose a model of thermonuclear synthesis of chemical elements that form renewable reserves of developed oil and gas fields. It was revealed that local zones of abnormally high production rates of production wells and, accordingly, large cumulative production at developed fields in Western Siberia are due to the restoration of recoverable reserves due to geosoliton degassing. Therefore, when interpreting the results of geological and geophysical studies, it is necessary to pay attention to the identified geosoliton degassing channels, since in the works of R. M. Bembel and others found that they contributed to the formation of a number of hydrocarbon deposits in Western Siberia. When interpreting the results of geological-geophysical and physicochemical studies of the fields being developed, it is recommended to study the data of the ring high-resolution seismic exploration technology in order to identify unique areas of renewable reserves, which can significantly increase the component yield of hydrocarbon deposits.

Abstract The 2014 Wood Review is a report reviewing UK offshore oil and gas recovery and its regulation, led by Sir Ian Wood. The report identifies and addresses key challenges in the UK petroleum industry, among them the lack of a strong regulatory body and a decommissioning strategy. The UK petroleum industry is mature, and Norway may benefit from UK's experiences in decommissioning. The article investigates the applicability of the Wood Review recommendations for decommissioning in Norway. The analysis of the recommendations in the Wood Review is carried out by a SWOT-analysis of the general recommendations with a high potential impact on decommissioning as well as the five recommendations specific to decommissioning. The recommendations in the Wood Review were broadly accepted by UK authorities and formed the basis for numerous initiatives aimed at improving policies and practices in UK decommissioning. The key initiatives are presented to illustrate how the Wood Review recommendations has been interpreted. A summary of the key differences between the petroleum industries and the regulatory authorities in Norway and the UK is provided for background. Decommissioning in Norway face similar challenges to those identified in the Wood Review. The analysis indicates that several of the UK initiatives following the recommendations in the Wood Review has the potential of improving decommissioning in Norway. Differences in regulatory regimes between the regions may complicate the implementation of some of the initiatives following the Wood Review in Norway. In most cases only minor changes to regulations and/or practices are required. Recent UK initiatives with a high impact on decommissioning include increased focus on sharing of information and lessons learned, increased collaboration, the development of a decommissioning strategy, benchmarking of decommissioning cost estimates for all projects and the development and publishing of annual UK decommissioning cost estimates. There are indications that the Norwegian Petroleum Directorate (NPD) and the Norwegian Ministry of Petroleum and Energy (MPE) are falling behind their UK counterparts in key areas. Norway has limited experience with decommissioning, and scrupulous analysis of lessons learned in other regions is essential. Decommissioning of Norwegian offshore infrastructure is a major undertaking and even minor improvements may have a substantial impact on personnel risk, risk to the environment or the total decommissioning expenditure. The Norwegian regulatory regime has been an integral part of the Norwegian petroleum industry's success in previous decades, and changes to the regime require careful deliberation. The recent implementation of initiatives aimed at improving decommissioning regulations and practices in the UK represents a unique learning opportunity for Norwegian authorities. The analysis suggest that Norway may benefit from adopting some of the UK initiatives following the Wood Review recommendations.

Flaring and venting contributes significantly to greenhouse gas emissions and environmental pollution in the upstream oil and gas industry. Present work focuses on a horizontal flow, multiphase ejector used for recovery of these flared gases. The ejector typically handles these gases being entrained by high pressure well head fluid and a comprehensive understanding is necessary to design and operate such recovery system. A CFD based analysis of the flow through the ejector has been reported in this paper. The flow domain was meshed and the mass and momentum equations for fluid flow were solved using commercial software CFX (v14.5). Euler-Euler multiphase approach was used to model different phases. The entrainment behavior of the ejector was investigated and compared for different fluid flow conditions. It was observed that for a fixed primary fluid flow rate, the entrained or secondary flow rate decreased linearly with an increase in pressure difference between exit and suction pressure. The higher was primary flow rate, the greater was the suction created ahead of the primary nozzle and greater was the amount of energy added to the entrained fluid.

Surfactant and polymer flooding are the vital techniques used in petroleum industry to enhance the oil recovery. Development and advancement in such techniques has occurred time by time to overcome the challenges of oil and gas recovery. However, micro fluid chips and its development provide a new way to understand the real time behavior of fluid flow in porous media. The essence of this study has been achieved by collecting the information from literature studies and sorted the useful information to organize the pattern of micromodels chip revolution. In this study, first precise review is conducted by the innovations of micromodel chips into timescale from 1952 till date. Second, advancement in micromodel chip technology is included based on different periods of time where micromodel chips have evolved from chip design to nano scale visualization of chips. Third, some recommendations are proposed based on evolution of micromodel chip technology that it not only requires less time but also minimizing the massive experimental setup and complications. The overall finding of this research propose that in current times some microfluidic reforms made recently has played versatile role in improving injection chemical selection and similar improvements are expected to be developed in near future.

Abstract Keeping pace with the rest of the world on reducing the greenhouse gas emission, Saudi Aramco embarked on an aggressive program to minimize or cut routine flaring and energy resources used in producing oil and gas through policies, standards and inhouse innovations. The innovative Unconventional Waste & Flare Gas Recovery System UFGRS has supported the corporate strategy to minimize or eliminate routine flaring with minimum CAPEX and OPEX. This paper present in detail the innovative Ejector Based Unconventional Waste/Flare Gas Recovery System (UFGRS) without using gas compressors. The objective of the project is to eliminate the hydrocarbon gas release to atmosphere for any upset flameout scenario from GOSP-A massive flare & relief system and continuously recover 1.825 Billion Standard Cubic Feet per year (1.825 BSCFY) of valuable purge gas with the lowest CAPEX and OPEX. Conventional Flare Gas Recovery System (FGRS) using gas compressors is the normal choice deployed in many facilities to recover the routine gas flaring but it was found to have high CAPEX and OPEX (maintenance, high power consumption & labor intensive) compared to the value of the recovered gas. Also, the compressors based FGRS is more complex and less reliable than the ejector (static) based FGRS. In addition, the innovative FGRS is capable of handling high turndown ratios compared to convention compressor based FGRS. Also, additional innovative parts of this idea is the integration with the existing compression system and the use of only static equipment like ejectors, pipes, valves and water seal drums to recover the waste/flare gas. The idea has very low operating cost compared to conventional flare gas recovery systems, apart from significant gas savings. The unconventional FGRS system was proven successfully in December 2020. The system is currently in operation for 8 months without any interruption and managed to eliminate the total design routine gas flaring rate of 1.825 BSCFY GOSP-A producing facilities. Also, the project resulted in reducing CO2 emission by 106,000 ton/year which positively contributed to the kingdom circular economy initiatives. To further enhance the ejector based FGRS, a US Patent No. 10,429,067 was granted in October 2019 to utilize the Ejector based FGRS concept for Emergency flare gas recovery. The innovative idea includes utilizing multiple ejectors in parallel with provision of different ejectors operating at different pressures that will allow the system to be used to recover flare gas over a range of different flow rates corresponding to different emergency release scenarios. Also, two new patents are under filing to utilize the liquid as motive fluid instead of the gas.

Unexpected faults are a serious production problem in numerous, complex and compartmentalised oil and gas fields, and are often the single most important restraint on recovery. Fractal mathematics has demonstrated a surprising degree of order in many natural, apparently random systems. It has been shown that fault patterns exhibit a similar order which could be used to indicate the presence of structures missed in the original interpretation of the seismic data and to predict faults below the approximate 20 m limit of seismic resolution. The potential for greater clarity and resolution opened up by this method may greatly aid field description and reservoir production. We will discuss the development of a comprehensive fault pattern characterisation quantatively with a set of parameters arising from non-linear methods of analysis. This allows for the standardised comparison of seismic interpretations and a precise method for testing interpretations from the same dataset. We will show how fractal mathematics may give a measure of the density of the fault set, the number of faults below the limit of seismic resolution, resolve small fault clusters below the limit of seismic resolution and aid in the description and analysis of fault sets.

Trapped concentrations of oil and natural gas in the earth will sometimes release vapors, whose presence and motion might be used to help infer where resources are located. Tests for carbon anomalies may be applied to search for hydrocarbons in the earth, and alterations in [Formula: see text] in the earth can be used to locate regions of subsurface gas flow. In a recent report we have observed both such anomalies over the Cement, Oklahoma oil and gas fields (Fleischer and Turner, 1984). Because of this result, whose generality is not yet known, it is of interest to know where other similar carbon and gas‐flow anomalies exist. (We should note that extensive examples of carbon anomalies in the soil have been presented; many of these are referenced in Fleischer and Turner, 1984.) This short note describes one such geochemical anomaly that has been observed using three methods of mapping—one radiometric, one isotopic, and one chemical. Testing whether this anomaly is associated with hydrocarbons is a logical next step that has not been taken.
