OGD Services Limited, Essar Global Fund’s investment in drilling services, recently drilled multi-lateral wells for a client at the Coal Bed Methane fields at Shahdol, Madhya Pradesh. The proposal to drill multilateral wells in CBM field was an exciting prospect as it was the first time ever in India.
A multilateral well is a well with two or more laterals (i.e. horizontal, vertical, or deviated) drilled through a window cut from a main mother well. This allows one well to produce from several reservoirs at once. Multilateral wells combine the advantages of horizontal-drilling techniques with the ability to achieve multiple target zones.
This concept of multilateral drilling has been around for long, however, it has never been implemented specifically for CBM projects as there are certain challenges in doing so.
There were detailed discussions with our client to firm up the well plans and align them with our rig capabilities. Our initial thoughts were that a much higher capacity rig would be required for horizontal drilling (under multilateral drilling). However, our team’s creative and proactive engagement with our client ensured deployment of our existing 750 HP rig, and completing drilling one well successfully. The learnings acquired while drilling our first well have been used to enhance our performance as we drill subsequent wells.
