Tested in multiple locations, the Continuous Circulation System has proved to be able to maintain a constant, steady downhole circulating pressure environment while making drill pipe connections.
New developments include enhancements to wireline and while-drilling resistivity logging, pulsed neutron logging, open- and cased-hole acoustic logging, formation testing, etc.
CWD wells in South Louisiana used rotary steerable directional technology for deviation control and delivered major savings compared to conventional offset wells.
When a chemical system alters formation wettability to intermediate gas-wet, capillary forces are decreased, and clean-up of trapped water is enhanced at low drawdown pressures.
These models allow the robust linkage of system tracts between exploration and field development activities, with operator data being integrated when available.
