GSPC plans five wells at onland Gujarat block

Vol 14, PW 17 (24 Feb 11) Exploration & Production

GSPC is expected to begin drilling two exploration wells and three development wells at its onland Gujarat block CB-ONN-2000/1 by September this year.

This 1424-sq km NELP-II block sprawls across the Gujarat districts of Ahmedabad, Gandhinagar, Mehsana and Anand. But a GSPC source says the planned drilling programme will focus on a 40.1-sq km area on the outskirts of Ahmedabad city.

GSPC has identified drilling sites for its five planned wells at Pisawada village, Sindhraj village, and Dholka town, which are southwest of Ahmedabad, and Ghuma village, which is west of the city. A public hearing to clear GSPC’s proposed drilling programme in these areas was called at Dholka on February 4 by state government authorities, and was attended by local villagers and farmers who raised no objections.

“Now we just need to get the green light from the environment ministry,” says GSPC. “We will then firm up our plans.

” It could take up to 90 days for environmental clearances to come in, he adds, after which GSPC will issue a tender to hire an onland rig. GSPC plans to drill each of the five proposed wells at CB-ONN-2000/1 to 3500 metres TD and says each well could take up to 45 days to drill.

GSPC drilled eight wells at this block in the 2004-05 fiscal: PK-1, PK-2, PK-3, PK-4, PK-5, PK-6, SE-1 and SA-1. “But only PK-1, PK-2, and SE-1 showed hydrocarbons and are producing oil,” we hear.

“The rest had some minor oil and gas ‘shows’ but nothing of commercial interest and were eventually abandoned.” Our source declines to share current oil production figures from these three CB-ONN-2000/1 wells but does tell us that GSPC drilled four more wells in 2008 in the 14.03-sq km Ingoli field which lies ring-fenced within the block.

“All these Ingoli wells are now also producing,” we learn.
