Start-up of Peripheral Water Injection

Abstract Peripheral water injection began into the pressure depleted Wafra Ratawi Oolite reservoir during July, 1998. Sixteen water injection wells are currently being utilized to inject 44,000 BWPD using low pressure charge pumps from the hydrocyclone and filtration skid. Design rate under high pressure injection is 200,000 BWPD using twenty-six injection wells. The water injection facility design, injector well location criteria, and reservoir performance data obtained from injectivity tests and spinner surveys are documented. Initial comparison between reservoir simulator predicted water injection rates versus actual injection rates provide some useful insight into the future success of the project. Recommendations regarding future operation of the injection facility and injection wells are highlighted.
