Great Eastern Energy Corporation Ltd. (GEECL) is the first Private Sector Company in India that entered this field. It is a part of the YKM Holdings Group. In December 2005, GEECL became the first Indian Company to be listed on the London Stock Exchange's Alternative Investment Market (AIM).

GEECL's pioneering effort is helping in maintaining the ecological balance in West Bengal's coal bearing areas where methane gas is escaping into the atmosphere and damaging the ozone layer. It will result in the demethanation of coal-beds and avoidance of methane emissions into the atmosphere.

GEECL is exploring and developing production wells for Coal-Bed Methane (CBM) in Damodar Valley (Raniganj coal-field), near the city of Asansol, West Bengal.

GEECL is pleased to state that it has struck Gas, and begun sales of CBM for the first time in India. The Gas-in-Place is 1.92 TCF as reported by Netherland, Sewell & Associates, Inc.
