Dynamic allocation of produced water during enhanced oil recovery
A recently granted patent (Publication Number: US11920453B2) outlines a method for dynamically allocating Produced Water (PW) during enhanced oil recovery (EOR) using low salinity or softened water. The method involves receiving measurement data related to the reservoir, PW, and injection water, determining a blending rate to create a blended injection fluid, and dynamically injecting PW and the blended fluid into EOR and disposal zones while maintaining specific injection rates and meeting voidage replacement requirements. The method ensures efficient utilization of PW in EOR operations.
Furthermore, the patent details the division of PW and blended injection fluid among various segments of the reservoir for different EOR processes, disposal, and injection limits. It highlights the use of PW in low salinity or softened water EOR streams, drive fluids, secondary and tertiary recovery modes, and disposal streams. The method also prioritizes the allocation of PW for reinjection, export in produced oil, and overboarding based on specific criteria. Additionally, the patent emphasizes the consideration of reservoir segments, injection requirements, pump capacities, and water compositions in the allocation process, ensuring optimal utilization of PW and injection water in EOR operations.
