New approach replaces jetting to deepen structural casing based on fracture gradient; builds on proven, casing-drilling technology, and creates a more favorable wellbore geometry to more frequently ...
If you are new to the oil and gas industry, most things look the same at first: pipes, heavy steel, and big equipment. But ...
ConocoPhillips, Tesco Corp., and Schlumberger Ltd. successfully tested rotary-steerable casing drilling in South Texas, combining directional drilling technology with casing drilling. "Each of these ...
New equations for calculating the collapse strength of worn casing can aid future casing string design. During any drilling, it is inevitable that drill pipe rotation and tripping will cause casing ...
HOUSTON — To hear the people at Baker Hughes tell it, a drill string — length after length of narrow pipe that can extend for miles into the earth — is far from a rigid assembly of high-strength steel ...
