Background and d Challenges of Geothermal Drilling

Geothermal reveir are typically found at depths of 1- 5 kilometers, where rock temperatures range from 150 ° C to over 400 ° C. Conventional rotary drilling, adapted from thee oil and gas industry, has been the workhorse for geothermal wells. However, geothermal environments present unique ostacles:

Managed Pressure Drilling (MPD) for Geothermal Wels

Managed pressure drilling (MPD) is a technique that precisely controls the pressure profile in thee wellbore to maintain a delicate balance between formation pore pressure and fractury gradient. In geothermal drilling, MPD offers several critiage:

MPD systems use a rotating control device (RCD) at thee well head, choke manifolds, and back- pressure pumps to maintain a closed-loop circation system. The Closed-Circuit Circulation Method (CCCM) variant has been successfuly deployed in geothermal fields in thee Philippines andd California.
