Managed Pressure Drilling (MPD) and Underbalanced Drilling (UBD) techniques represent significant advancements in the safe and efficient extraction of hydrocarbons. MPD employs sophisticated control ...

A slide and compound drilling model calculates build-up rate (BUR) of a single bent-angle motor assembly using a physical model and genetic-algorithm back propagation (GA-BP) regression analysis. A ...

Changes in directional drilling and surveying practices could lead to a reduction in positional errors arising from nonconstant wellbore curvature. Part 1 of this series (OGJ, Oct. 27, 2003, p. 51) ...

The proposed method can provide deeper insights into the sedimentation process during drilling, thereby improving the efficiency and reliability of foundation construction practices in geotechnically ...

In a full-scale demonstration on an oil rig near Houston, Texas, Quaise Energy showcased its new drilling technique capable of reaching superhot geothermal resources 2 to 12 miles beneath the Earth's ...

RC Crawford woke up one day with an idea about how to make drilling for water cheaper in poor countries. His dream involved designing a drill that uses a technique called reverse circulation. The ...

A new drilling technique is opening up vast fields of previously out-of-reach oil in the western United States, helping reverse a two-decade decline in domestic production of crude. Companies are ...
