Background
For monobore wells in the Ghawar field, a Middle East operator typically performed a dedicated scraping run before running an individual high-pressure testing packer. The high-pressure test at the top of the liner required two dedicated runs, which took 2.5 days or more. To save time, M-I SWACO proposed adapting the WELL COMMISSIONER liner-top test tool for high-pressure testing in addition to the standard negative inflow test.
