Drilling in the Menengai high temperature geothermal field has been on-going since early 2011, February 2011 when the first well, MW01 was spud in. total of seven 2000HP rigs are currently drilling in Menengai with one top holing rig used to top hole wells to anchor casing depth of between 400-500m. Three (3) of the seven rigs are still under commissioning. For the top holing, Atlas Copco predator 200 Klbs rig is used. The wells design for the Menengai wells is a regular well design with hole sections of diameter; 26″, 17½″, 12¼″ and 8½″. The hole sections are cased with casings of diameter 20″, 13⅜″, 9⅝″ and 7″ slotted liners which are set inside the 9⅝″ casings. Both vertical and directional wells have been drilled with the kick off point for the drilling wells below the anchor casing in the 12¼″ hole section |
