CBM Exploration Services

Coalbed methane (CBM) or coal-mine methane (CMM) is a form of natural greenhouse gas, which remains trapped in underground coal seams and is extracted, not only as a safety measure prior to mining the coal, but also for various domestic, commercial and industrial purposes. CBM is considered to be the most potential source of clean energy and hence is used as a fuel for power generation through gas fired generators.

CBM Exploration-Wireline Core Drilling

Coal cores can be obtained with different techniques including conventional & wireline coring. Conventional coring is a cumbersome process, involving the removal of the entire string of drill pipes, for the recovery of the core, thereby resulting in long trip times of an hour or more. As coal samples begin to de-sorb gas while being lifted from the bottom of the well, such long trip times can result in loss of large volumes of methane gas. As an alternative, many operators now-a-days use wireline-coring technique, which can bring samples to the surface in 15 to 20 minutes, significantly reducing lost-gas volumes.
