Deep Water Disposal (DWD) project started in 1995 to process the main facility excess water output. A side-effect of this DWD injection into the shared Mehwis formation is a pressure support to the nearby fields, the impact of DWD rates can be seen clearly on measured pressures, where-initially before the start of DWD-the field was in depletion mode, after which the pressure stabilized after stable DWD rates. Similarly, recently the decline of nearby fields pressure can be noticed as a response to lower DWD rates. This study aims to evaluate the extent of the pressure support in nearby fields from DWD and the required disposal rate to maintain the desired pressures, and hence ultimately reclassify that part of deep-water disposal volume to water injection (WI), without sending the remainder water to shallow disposal site.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
