Botswana Coal Bed Methane Production Well Drilling

Drilling CBM Production Wells in Africa.  Wells are surface set with 8 5/8″ surface casing through Kalahari Sands and anchored into the basalt formation.  Rigs are set up with conventional circulation drill pipe and down hole hammers.  Wells are drilled with twin 1,150 x 350 compressors and a 2,000 psi booster, to set 5 1/2″ longstring.  Insitu water flows are high and are supplemented with water injection and foam to limit well bore damage as much as possible.

Local crews were trained in gas well drilling and supervisors are trained in safe production well operations.  Wells are orifice tested while drilling for gas and cementing of the wells is completed to limit weight of cement on the formation.
