A new API recommended practice (RP) intends to provide a guide for managing annular casing pressure in offshore wells. An August workshop in Houston reviewed the draft proposal and solicited input ...

HOUSTON, Nov. 14-- The US Mineral Management Service has proposed that wells with subsea wellheads completed after Jan. 1, 2005, have the means for monitoring casing pressures. MMS issued a notice of ...

The casing lines the wellbore, keeping it insulated while protecting the soil and groundwater around it from being contaminated by mud, fracking fluids, and more. It is built to resist high loads and ...

New oil and gas development techniques like horizontal drilling and high-volume hydraulic fracturing have dominated public concern in recent years about groundwater contamination in oil and gas basins ...

Once a well has been drilled, if it is to become a production well, the well must undergo completion. While drilling a well cuts through the rock formations and allows drilling engineers to reach the ...

Well casing is the set of concentric steel strings run and cemented in a borehole to provide structural support, isolate formations, and create a pressure-tight conduit for drilling and production. It ...
