... Abstract Enhanced oil recovery (EOR) techniques utilizing low-salinity water (LSW) are advancing owing to their favorable technical and economic viability. LSW flooding entails the injection of a modified-composition brine into oil reservoirs with a lower concentration of the potential...

... States, there has been significant progress in CCS project development in such formations subject to Underground Injection Control (UIC) Class VI guidance. Concern for contamination of underground source of drinking water (USDW) zones is regulated by limiting CO 2 injection near faults. This represents...

... Abstract We investigate the hazards of leakage and induced seismicity for a potential CO 2 storage site in the southern San Joaquin Basin, CA. Total injection is scheduled for 12.3 MtCO 2 with variable rates over 18 years followed by 100 years of monitoring. We extend our prior analysis from...

... credits are considered. In geological storage, the buildup of injection pressure is a pivotal factor for storage operations within ultralow permeability reservoirs. Another challenge is the exsolution of CO 2 from brine during the production process in geothermal operations. The produced CO 2 , flowing...

... reduced somewhat during the depletion and then increased during the CO 2 injection. The porosity, however, did not fully recover after the injection process was completed. The maximum subsidence of the storage formation top reached almost 24 cm at the well location once the depletion completed...

... flow test using single-phase brine and a two-phase oil/brine flow test. Secondly, a fluid-fluid test was performed to assess the compatibility of connate and injection water under both ambient and reservoir conditions (Reference). These tests aimed to analyze the interaction between the rock...

... flaring in case of temporary gas plant shutdown. The project’s main objective is to evaluate technically the feasibility of gas re-injection in the Bakken formation as a means to temporary store gas, increase oil recovery, reduce flaring and maintain compliance. A flow simulation model was created...

... Abstract We evaluate the potential for CO 2 leakage along pre-existing wells and through the formation caprock as well as the probability of inducing slip on faults during CO 2 injection and storage in a saline formation in the Southern San Joaquin Basin. Our model considers 0.6 Mt CO 2 /y...

... cumulative oil production and minimize cumulative polymer injection. The proposed optimization strategy follows a sequential step: well rate optimization followed by polymer concentration optimization. In the first stage, streamline-based method is used to adjust the water injection rate and liquid...

... Abstract Produced water is commonly co-produced with oil and gas production and requires safe disposal in subsurface reservoirs. Knowing the amount of produced water that can be safely injected into the reservoir is important for disposal operations. While the methods of reservoir hydrocarbon...

However, related to the experimental evaluation of storage capacity potential with the CO 2 EOR displacement mode and the long-term storage of CO 2 in situ in the formation experienced by CO 2 flooding...

...Proposed Solution The proposed solution involves a seasonal cycle of injecting associated gas (which would have otherwise been flared) into the original oil reservoir and producing electricity based on demand. To better convey the seasonal cycle of this project, the model injected associated...

...) for most SAGD projects ranges between 2 and 4 bbl steam/bbl oil. Nevertheless, some projects are still experiencing SOR of over 4 bbl/bbl due to the aggressive steam injection. Despite the efficacious evidence and enormous contribution to oil production, many questions regarding the current SAGD project...

... Abstract Oil production enhancement from mature fields through polymer injection has gained elevated interest due to the improved mobility and conformance controls. The suitability of polymer with harsh reservoir condition and its insitu performance dictate the success of polymer-augmented...

... Abstract Laboratory experiments have demonstrated that injecting urea solution as a CO 2 -generating agent into an oil reservoir may significantly enhance oil recovery. When the reservoir temperature is above 50 °C , urea is hydrolyzed to carbon dioxide and ammonia. This technology overcomes...

... Abstract Replacement of voidage relates to the method of injecting liquids to replace oil, water and gas inside the reservoir. The technique for voidage replacement is the volume of injected fluids in the barrel over the volume they got produced. Injected liquids may be wasted outside...

Production commenced in December 1981 and has cumulated to date more than 2.5 Bstb oil through water-flooding, immiscible water-alternating gas (IWAG) and miscible water-alternating-gas (MWAG) injection. Currently, the field produces about 60,000 stb/d...
