Jul 14: Drilling of these development wells which includes horizontal / hi-tech wells in addition to conventional wells will not only arrest the natural decline in field production but in fact is expected to augment production.
8Dispersion modeling has been carried out for electric rig of 1250 KVA for some of these wells.
8Depths of drill wells will be in range of 800 to 2000 meters and water based mud will be used for drilling. This would typically take 15 - 35 days.
8Power requirement for drilling operation will be generated by four DG sets of 1250 KVA (one on stand by), each DG set will consume 290 liters/hours of high speed low sulphur diesel.
8It is expected that 1 barrel per well of used oil will be generated during drilling operations  which will be disposed off through authorized recyclers.

ONGC's Ahmedabad Asset- I: Additional 268 wells planned for exploiting Gamji prospect

ONGC has now increased the number of development wells to be drilled from 138 to 406   in Area II and Area IV of the Ahmedabad Asset in Kheda, Gandhinagar and Ahmedabad districts of Gujarat.
8Cost of drilling a vertical well is Rs. 4 crore while that of horizontal well is INR 12 crore, hence 390 vertical wells and 16 horizontal wells that are planned to be drilled will carry a total price tag of  Rs.1752 crore.
8The increase in wells is mainly done after ONGC updated the reservoir data for the Gamij field, which comes under Area IV of Ahmedabad Asset.
8Owing to this updation, ONGC now wants to monetize the Gamij Field's excellent potential.
8So in addition to 52 wells, an additional 268 wells will be drilled in Gamij field.
