fax 01-972-952-9435. AbstractThis case history paper describes the use of a bottomhole kickoff assembly (BHKA) tool to place openhole plugs in a high-temperature well. The well was a 6 ½-in. diameter borehole with 52° deviation and 174°C (345°F) bottomhole static temperature (BHST). Depth was 5775 m (18,946 ft). Even though these extreme conditions were anticipated, they were discussed with the operator because two earlier attempts to achieve a kickoff had failed.In this successful kickoff operation, the BHKA was tagged 1 m (3.3 ft) below the calculated top of cement and was tested to 6 tons over the plug, using a 165-mm (6 1/2-in.) roller cone bit. Conditions for both the tool and cement slurry were extreme. Kickoff was successfully accomplished during the first 8 m (26 ft) of the BHKA plug; formation cuttings of 99% were reported.

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.
