Alphageo starts 2D shoot for ONGC in Rajasthan

Vol 21, PW 1 (05 Oct 17) Exploration & Production

Alphageo has begun shooting 2D in unexplored areas of Rajasthan under an ONGC contract won last year to collect data for the National Data Repository and the OALP regime.

PETROWATCH learns a 25-strong Alphageo team began work on September 7 in the rural Bhadvasi and Saranwas areas outside Nagaur city within the desolate Bikaner Nagaur basin, an alluvium-sand covered region stretching across the border into Pakistan and believed by many, including Oil India, to hold the potential for a huge oil and gas discovery. Alphageo has mobilised four large truck-mounted vibrator machines in Bhadvasi and Saranwas, with a capacity to measure seismic data to a depth of seven or eight-km sub-surface.

After beginning at Nagaur, an arid area located midway between Jodhpur and Bikaner, the team moved 20-km away to Kuchera village. An ONGC source says any indication of oil, gas or any other mineral deposit will prompt it to consider also shooting 3D and 4D.

He adds ONGC is supporting Alphageo by keeping track of crop damage caused by the survey so farmers can be compensated swiftly, within a 30-45 day timeframe. Based on the exploration data available, ONGC is hoping to find oil or gas near Bikaner, Jodhpur, Churu and Sikar cities and Shibbalaji, Bhadvasi, Ena and Kuchera villages.

Alphageo won a Rs1300cr ($195m) contract from ONGC in June 2016 to shoot 26,905-lkm of 2D, or seven of 11 sectors across India under a tender to shoot 40,835-lkm in total, according to our archives.
