Also known for providing tourism services and representing CGGVeritas in India, Pan India Consultants is preparing to kick off exploration work at its NELP-IX onland Gujarat block CB-ONN-2010/5.

Gurgaon-based Pan India is expected to issue tenders by August to shoot 49-sq km of blanket 3D and drill four exploration wells for $8.75m for which it will need a 750-1000 hp rig to drill each well to 3000 metres or 'basement', targeting Cambay and Olpad geological formations. Pan India has organised a public hearing on June 25 at Chanasma town to clear the campaign which will take place in Patan district.

CB-ONN-2010/5 sits in the northern part of the Ahmedabad-Mehsana tectonic block of the Cambay basin near ONGC-operated oil and gasfields Kalol, Jotana, Sobhasan, Bechraji and Balol. Lanwa and South Patan fields are southeast and northwest of the block.

Pan India estimates drilling will take 90-120 days while testing will take 15-20 days. Under consideration is reflection methodology for its 3D survey, using reflected seismic waves to estimate subsurface properties.

Well locations have yet to be finalised. Earlier ONGC shot 2D at the block and in 2007 also acquired 3D.

Five exploratory wells were drilled but abandoned: CVAA-1, Mehsana-17, Mehsana-Horst-1, DNDR-1 and Lanwa-1.
