ONGC hikes Nawagam crude storage by two tanks

Vol 12, PW 13 (13 Nov 08) Midstream & Downstream

Gujarat-based oil companies that want to increase crude production will be happy to hear ONGC is on schedule to increase the capacity of its Central Desalter Plant at Nawagam, earlier criticised for supplying contaminated crude oil to a 13.7m t/y refinery belonging to Indian Oil at nearby Koyali.

PETROWATCH learns ONGC is planning to increase the crude storage capacity of its four-tank Nawagam facility from 120,000 cubic metres to 180,000 cubic metres with the addition of two more storage tanks measuring 30,000 cubic metres each. Last month, contractors working for ONGC completed construction of the fifth storage tank, which is now ready to be commissioned.

Work on the sixth tank is underway. Almost all crude processed at Nawagam comes from ONGC oilfields in north Gujarat that fall within the Ahmedabad and Mehsana assets, as well as from explorers GSPC, Joshi Technologies, Prize Petroleum and Selan Exploration.

Around 5800 tonnes (40,000 b/d) is delivered to Nawagam from the Mehsana oilfields, while 4600 tonnes (32,200 b/d) is delivered from the Ahmedabad oilfields. Ahmedabad crude from Limbodara, Kadi, Viraj, south Kadi, Kalol and the Jhanora-Sanand oilfields travels through an eight-inch diameter pipeline to a Crude Tank Farm (CTF) at Kalol and then through a 14-inch diameter pipeline to Nawagam for processing.

Crude from the Motera field on the northwest periphery of Ahmedabad is delivered to the Kalol CTF by tanker. Another eight-inch diameter pipeline delivers crude directly to Nawagam from the Ramol, Nandej and Vasana oilfields east of Ahmedabad.

One company that stands to benefit immediately from the expansion at Nawagam is GSPC, which wants DGH permission to increase production from its Dholka oilfield to 3000 b/d from 700 b/d. Besides GSPC, Selan supplies crude to Nawagam from its Bakrol, Indrora, Lohar and Ognaj oilfields; Prize supplies crude from the Hirapur, West Bechraji and Khambel oilfields; Joshi supplies crude from Wavel and Dholka.
