Our DUAL-ACTION BYPASS SUB circulating valve is designed to run in the cleanup string when it is desirable to jet the riser and BOP while running in hole (RIH), pulling out of hole (POOH), or both. The valve also can be used nearer the bottom of the string as a bypass valve above a drilling motor or small-diameter tailpipe.
The tool is run in the open position to jet and clean as it moves through the riser and BOP. Afterward, the external jetting ports on the sub are closed to resume circulation. The jets are reopened to allow jetting to recommence when POOH.
M-I SWACO offers a wide variety of specialized tools—from liner top test tools and casing cleaning tools to ancillary and customized tools—and filtration services to protect and preserve fluids quality.Download Catalog
