Focus gearing up to drill ninth well at Rajasthan block

Vol 11, PW 15 (29 Nov 07) Exploration & Production

Privately owned Indian explorer Focus Energy is about to begin â€کCased Hole’ testing of exploration well SSF-2 at RJ-ON/6, a pre-NELP exploration block in Rajasthan on the border with a series of prolific gasfields in Pakistan.

Spud on April 5 this year, SSF-2 was drilled to reach TD of 4274 metres in late October and PETROWATCH learns Focus is now planning a series of Drill Stem Tests to assess the well, subject to Operating and Management Committee approval. “The gas logs were good,â€‌ we hear.

“But we need to look at the DST results for a better idea.â€‌ Testing is expected to last around two months and Focus should be in a position to release testing results from SSF-2, its eighth exploration well on the block, in mid-January.

And if past results are anything to go by, there’s a high probability they won’t disappoint. A seventh well drilled by Focus in March this year called SGL-2 flowed an impressive 18m cf/d (480,000 cm/d) but it was in September last year that Focus surprised everybody with its disclosure to the DGH that the fifth well SGL-1 flowed 21.25m cf/d through a three-quarter inch choke from an eight-metre pay zone between 3,159 metres to 3,167 metres in the â€کPariwar’ formation.

Looking ahead, Focus has identified the location of its ninth well and is preparing to â€کspud’ by the middle of next month (December). This well, so far with no name, will be drilled to TD of 3800 metres, again pending approval from ONGC, who is the block’s licensee, and the DGH.

A tenth and final exploration well will follow. “Focus has already exceeded its drilling commitment in terms of metres drilled,â€‌ we hear.

Seismic acquisition at the block is underway simultaneously, with Focus beginning a 200-sq km 3D survey in July using in-house teams. By this month, it had acquired 130-sq km, which is being processed and interpreted simultaneously.
