Five battle for Oil India seismic job in Mizoram

Vol 16, PW 4 (06 Sep 12) Exploration & Production

Five companies will be battling it out to win an imminent tender from Oil India to shoot 400-sq km 3D in the remote north eastern state of Mizoram.

Onland Indian seismic contractors Shiv Vani, Alpha Geo, Asian Oilfield Services, and IndianOilTanking, plus Vienna-based CAT Geodata, sent in EoIs to Oil India in July for the job at NELP-VI block MZ-ONN-2004/1 in the Assam-Arakan basin near Myanmar. All are expected to respond later this month (September) when Oil India publishes a tender to shoot ‘loop’ 3D at the 3213-sq km block, which straddles the Lunglei, Aizawl, Serchhip and Mamit districts of Mizoram, which shares a border with Bangladesh to the west, and Myanmar to the east.

“Shooting 3D will not be difficult,” reports Oil India. “But interpreting it will be challenging because of the ‘random geometry’ and overlapping thrusts.

” Unlike conventional 3D, ‘loop’ 3D is shot in curved lines, logical for a hilly state like Mizoram with poor roads and little infrastructure. Oil India, he adds, will float a separate tender in October to process and interpret the 3D.

Interpretation will not be done in-house. Shooting is slated to begin in December this year after the monsoon rains, while processing and interpretation results must be submitted by next July.

Oil India estimates the whole job (acquisition, processing and interpreting) will come to around Rs60cr ($12m) in total. Five drilling locations have already been identified from 1352-lkm 2D shot by Asian Oilfield Services in May this year and a separate tender for a 2000-hp rig and allied services is also expected this month.

Oil India has tentatively scheduled May next year as the start date for its five-well drilling programme at this block.
