HPCL, in March 2013, had signed an MoU with the Rajasthan government for setting up the refinery-cum-petrochemical complex in the Thar desert near the oil discoveries made by Cairn India.
But the refinery never took off as a change of guard in the state led to Rajasthan government putting on hold the fiscal incentives for the project.
"We are talking to the state government explaining to them the reconfiguration of the unit," HPCL Director (Refineries) Vinod S Shenoy told PTI here.
"The project will cost more than the earlier estimate of Rs 37,000 crore," he said, adding that Engineers India Ltd (EIL) has been asked to do a feasibility study.

While stating that the cost numbers have not yet been worked out, he said the project may need Rs 4,000-5,000 crore more.
Shenoy said the discussions with the Rajasthan government have not reached the stage of negotiating the exact fiscal concessions that the company would need to set up the project.
Half of the crude oil requirement at the proposed refinery at Barmer was to come from the neighbouring oil fields of Cairn India. The rest was to be imported crude.
At that point, HPCL had asked the state government to extend fiscal benefits like the ones extended by Gujarat and Odisha to new refinery projects to make the Barmer unit viable. The concessions included 50 per cent exemption in excise duty and the state government picking a small stake in the project.
In 2012, HPCL entered the fray and proposed to take 51 per cent stake in the same. ONGC, which originally had the authorisation from the government for processing the Barmer crude at the proposed refinery, willingly made way for HPCL.
Cairn India, which holds 70 per cent interest in the fields, currently produces about 1,65,000 barrels per day oil (8 million tonnes a year) from the Rajasthan fields.
Sources said the Rajasthan government in 2013 had started the process of land acquisition of about 926 hectares, but it was put on hold.
For HPCL, which has only two refineries in Mumbai and Visakhapatnam, the project would have helped meet fuel demand in the north.
