... half-life response amphoteric surfactant injection Introduction and Background Worldwide energy strategies must consider climatic and societal challenges linked to expanding energy needs ( IEA, 2023 ). Fossil fuels are major contributors to confronting the primary energy demand...

... for EOR. Incremental recovery factor for EOR was less than 10%, varying with the well spacing and injectant fluid. Faster breakthrough occurred as the spacing size decreased, particularly for gas injection, due to high permeability streaks or even when using constant property model. The optimal...

... Water Alternating Gas (WAG) Enhanced Oil Recovery (EOR) is a promising method for increasing the recovery of oil from mature oil fields. In WAG EOR, alternating injections of water and gas are used to sweep the remaining oil in the reservoir, increasing the amount of recoverable oil. The sweep...

... The 1 st sequence of the phase has resulted into unexpected low oil gain. The team has investigated the causes via revising the injection profile and data gathering. It was apparent that the increase of water injection salinity has impacted the functionality of the surfactant. The following...

... Abstract Global efforts towards environmentally safe waste disposal necessitate Waste Slurry Injection (WSI) wells to be monitored for operational compliance, safety, sustainability, and optimization of waste disposal and vaulting capacity. Pressure Transit Analysis (PTA) is a comprehensive...

... The hydrocarbon gas injection pilot consisted of two phases ( Figure 1 ): Pre-flush water injection phase carried-out between May 2016 and April 2019. Hydrocarbon gas injection phase starting from Sep 2021 to Sep 2022. The area of interest comprises: sedimentary rock...

... Abstract The current development strategy of this field is focused on the oil rim, it involves downdip water injection and gas injection in the gas cap to maintain the pressure. A co-development of the oil rim with the large gas cap is being tested at pilot scale and considered at large scale...

... capacity and allows for the repurposing of existing idle wells for gas re-injection, which is a method of routing gas lift gas, typically used to assist oil production, back into the reservoir through downhole gas lift valves (GLVs). The production technology team's assessment of the idle wells...

As the acid interacts with the carbonate rock, there will be alterations in temperature profiles. The effectiveness of the acid treatment is mainly dependent...

... consumption), the team has successfully piloted an initiative to increase the polymer molecular weight from around 20 to 25 million Daltons, hence, reducing polymer dosage by 20-25% to achieve target viscosity of 15 cP. This led to the implementation of full field injection of the high molecular weight...
