AbstractChemical enhanced oil recovery (EOR) processes are usually used as additives for hydrocarbon production due to its simplicity and relatively reasonable additional production costs. Polymer flooding uses polymer solutions to increase oil recovery by decreasing the water/oil mobility ratio by increasing the viscosity of the displacing water. The commonly used synthetic water-soluble polymer in EOR application is partially hydrolyzed polyacrylamide (HPAM). However, synthetic polymers in general are not attractive because of high cost, environmental concerns, limitation in high temperature, and high-salinity environment. Guar gum is an environmentally friendly natural water-soluble polymer available in large quantities in many countries and widely used in various applications in the oil and gas industry especially in drilling fluids and hydraulic fracturing operations; however, very limited studies investigated on guar as a polymer for EOR and no any study investigated on its uses in high-temperature and high -salinity reservoirs. The objective of this study is to confirm the use of guar gum as a natural polymer for EOR applications in sandstone reservoirs and investigate its applicability for high-temperature and high-salinity reservoirs. The study experimentally investigated rheological characteristics of a natural polymer obtained from guar gum with consideration of high temperature (up to 210 °F) and high salinity (up to 20% NaCl) and tested the guar solution as EOR polymer. The results of this study show that the guar solution can be used as an environmentally friendly polymer to enhance oil recovery. Based on the results, it can be concluded that guar gum shows shear-thinning behavior and strongly susceptible to microbial degradation but also shows a very good properties stability in high temperature and salinity, where in low shear rate case, about 100 cp viscosity can be achieved at 210 °F for polymer prepared in deionized water. Guar polymer shows good viscosity in the presence of 20% NaCl where the viscosity is acceptable for temperature less than 190 °F. Also, the flooding experiment shows that the recovery factor can be increased by 16%.

Scientists are developing improved surfactants for enhanced oil extraction that have superior capabilities while being environmentally friendly and capable of strong operational tolerances to pH, salinity, and temperature.In laboratory tests, numerous green surfactants synthesized from vegetable oils and other plant-based materials matched or exceeded the capabilities of conventional synthetic surfactants. Plant-based zwitterionic surfactants are reported to have strong interfacial reduction values and operational tolerances

Energy is a basic human need which continues to increase every year. The fact is that the production of energy such as petroleum in Indonesia has decreased due to the depletion of petroleum reserves. The increasing consumption and increasing demand for energy has prompted the government to implement renewable energy planning. The solution that can be offered is Enhanced Oil Recovery (EOR) technology. Meanwhile, one of the developments in EOR technology that is environmentally friendly and able to increase oil recovery well is Microbial Enhanced Oil Recovery (MEOR). In the MEOR system, a bioproduct injection component called biosurfactant is used. The performance of biosurfactants in the system can be done by reducing the interface stress and mobilizing oil in the rock. The production of biosurfactants can be increased with the help of secretion of microorganisms. Based on the literature obtained, Bacillus licheniformis is a type of native bacteria that has the potential to produce biosurfactants with lipopeptide characteristics. Bacillus licheniformis is able to produce several extracellular enzymes, namely amylase, amino, peptidase, metal protease, lactamase, endo-N-acetyl glucosaminide and lipase. In addition, several studies have shown that Bacillus licheniformis has the potential to be applied to MEOR, bioremediation and industrial biotechnology. However, the biosurfactant produced from the bacterium Bacillus licheniformis requires a substrate to increase oil recovery. One type of organic substrate that can be used is tofu liquid waste. Tofu liquid waste contains high organic and nutrient materials consisting of 90.72% water, 1.8% protein, 1.2% fat, 7.36% crude fiber, and 0.32% ash. The author sees the potential use of tofu liquid waste because of its environmentally friendly nature. Therefore, the author offers an idea entitled The Potential Application of Bacillus Licheniformis Biosurfactant and Tofu Liquid Waste as an Application of MEOR Technology.

AbstractThe current global economic trends of low commodity prices for hydrocarbons, competition due to the emergence of shale oil and gas, as well as the decline in production from mature oilfields in Trinidad and Tobago (TT) have fuelled the need for the implementation of efficient and enhanced oil recovery methods. Of particular concern locally is the issue of decreasing oil production and increasing production costs in mature oil fields due to the prevalence of organic deposits (paraffin or asphaltenes), which results in the coating of production tubing causing the plugging of surface equipment, pipelines, perforations and pore spaces in the geological formation. Major deposition compound paraffins and asphaltene are soluble in condensate, which is relatively cheap and is produced as a by-product and flared in TT, and it is already used as a pipeline diluent and cleaner for deposits. The strategy of utilizing this “waste” solvent as an economical and environmentally friendly strategy for EOR was worth investigation. The FR 1346 RD well was selected for evaluation, and a pilot test was conducted using the compositional reservoir simulation model (CMG–GEM). Laboratory studies were conducted using a constructed pressure permeability flow chamber, and results from the device indicated that an asphaltene plug decreased the permeability by approximately 24%, but after treatment with condensate, there was an improvement in permeability of approximately 10% (300 md to 420 md). Tuning of the simulation model incorporating the laboratory-derived permeability data resulted in an increase in production rate to 35 bopd, which matched very closely with the field pilot well test result of an increase of 46% (from 20 to 39 bopd) when the condensate soak was performed. This increase translated in an overall gain of 30,531 bbls of oil associated with a financial gain of approximately $4.7 MM TT per well over the 16-year period. Injection types including condensate, carbon dioxide and nitrogen yielded the production of the same order. This study offers compelling evidence that the use of produced condensate in EOR is an economically and environmentally friendly strategy in TT.

The features of evaluation of the effectiveness of flow deflection technologies of enhanced oil recovery methods. It is shown that the effect of zeroing component intensification of fluid withdrawal leads to an overestimation of the effect of flow deflection technology (PRP). Used in oil companies practice PRP efficiency calculation, which consists in calculating the effect on each production well responsive to subsequent summation effects, leads to the selective taking into account only the positive components of PRP effect. Negative constituents — not taken into account and it brings overestimate over to overstating of efficiency. On actual examples the groundless overstating and understating of efficiency is shown overestimate at calculations on applied in petroleum companies by a calculation.
