Reliance set to begin CBM development at Sohagpur

Vol 10, PW 1 (04 May 06) Exploration & Production

Reliance is winning plaudits from industry and the DGH for the speed and efficiency of its work at CBM blocks Sohagpur East and Sohagpur West in Madhya Pradesh.

They have done a tremendous job, reveals an official. They have chosen consultants who are guiding them well.

Adds a contractor: Reliance is much more efficient then the other players. Its work programme is like in the rest of the world.

Reliances appointment of CBM consultant Advanced Resources International in the US appears to be paying dividends. In June this year, Reliance begins Phase-II exploratory drilling at its 495-sq km Sohagpur East and 500-sq km Sohagpur West blocks followed by an aggressive drilling programme beginning in August.

Under consideration is a 26-well programme with an option to drill another 26 wells using the mobile Soilmec G55 rig from Mitchell Drilling and other rigs that Mitchell plans to bring to India. Soilmec G55 is presently at the Raniganj block in West Bengal where it is half way through a 20-well development programme for Great Eastern Energy.

Last year Reliance surprised the DGH by drilling 16 core holes and ten exploration wells across the combined 995-sq km area of Sohagpur East and West in a record six months. Under its Phase-I work programme that ended on 29th April last year, Reliance committed to drilling eight core holes and only two exploration wells at each block.

Work on delineating the prospect is underway and Reliance has identified the Fairway Zone on which development will proceed. No one knows for sure how much the two blocks will produce until results come in from the development programme.

What is known is that Reliance is still de-watering the ten Phase-I wells and flaring any gas that comes out. First indications are promising.

They are producing gas at ten cubic metres per tonne from some wells, reveals a source. DGH studies predicted only four cubic metres per tonne.
