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 ...

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 ...

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 ...

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) ...

Many types and sizes of drilling machines are used in manufacturing. They range in size from a simple bench mounted sensitive drill press to the large multiple-spindle machines able to drive many ...

What if the key to unlocking a cleaner, more sustainable energy future was hidden just beneath our feet—but we lacked the tools to reach it? Despite geothermal energy’s immense potential to power ...

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 ...

Kalamazoo Resources has initiated a drilling programme of approximately 14,000m at its Ashburton Gold Project in Western Australia’s Pilbara region. The initiative involves drilling at the Mt Olympus ...
