SDI has pioneered many new technologies which have greatly assisted in the development of coal seam gas (CSG), commonly called coalbed methane (CBM).
Drilling horizontal laterals in CBM/CSG reservoirs can be quite challenging, particularly when the goal is placing the lateral in a specific part of the coal seam with minimal undulations.
SDI has been drilling successful CBM/CSG projects for over a decade; with five thousand successful laterals and counting.
CBM / CSG Drilling Technologies
While drilling a lateral in coal, the wellbore is typically steered using focused gamma ray measurements on the high side and low side of the wellbore. The near bit instrumented Smart Motor (Sci-Driver™), collects real-time gamma ray logs for both the upper and lower half of the wellbore, while rotating. This proves to be especially beneficial to the horizontal drilling operations, considering most of the footage in a lateral is drilled in the rotary mode.
