Continuous circulation system adds efficiency in drilling difficult/HPHT wells

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.

Simple managed pressure drilling method brings benefits

The first three wells to use a new closed-loop MPD system have confirmed its effectiveness on multiple well types.

Managed pressure drilling-What is it anyway?

Many ways are available to determine downhole pressure environment limits and manage the annular hydraulic pressure profile.


Recent advances in well logging and formation evaluation

New developments include enhancements to wireline and while-drilling resistivity logging, pulsed neutron logging, open- and cased-hole acoustic logging, formation testing, etc.

The importance of accurate temperature testing for cementing

Small-liner cement designs can be improved by the API Plug Schedule.

Two salt dome wells successfully drilled using casing while drilling

CWD wells in South Louisiana used rotary steerable directional technology for deviation control and delivered major savings compared to conventional offset wells.

Wettability alteration used for water block prevention in high-temperature gas 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.

Casing while drilling and stage-tool cementing combined to mitigate downhole conditions

While drilling in Colorado's Piceance basin, two technologies cut drilling NPT by 21%.
