Bradenhead cementing, where pressure is applied to the entire casing string, improves cementing operational efficiency and economic viability. It isolates the vertical part of the wellbore from ...

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 ...

Purpose: Establish the structural and pressure-containing interface at the seabed for an offshore well, enabling safe top-hole drilling, pressure control, and subsequent casing hanger landings under ...

A large number of simulation tests helped determine the causes of casing wear problems in Tarim oil field. The tests determined casing wear mechanisms and the effect of wear parameters such as lateral ...
