"The new policies concerning the oil and mining sector, as referred in the reply of ONGC to the NSE and the BSE, though not amply clarified in the reply, were pertaining to policies such as purchase preference policy, steel policy, GST policy and not regulatory policy," ONGC said in a statement.

Clarifying on its last week's filing to stock exchanges, Oil and Natural Gas Corp (ONGC) said the new policies it had cited for a possible delay pertained to local purchase preference policy, steel policy and GST policy.

ONGC, India's biggest explorer, has shortlisted US oil service companies Halliburton, Schlumberger and GE subsidiary Baker Hughes to submit proposals on boosting production from two onshore fields, according to a document seen by Reuters.

Officials said the ship, Sagar Bhushan, was under repair at the shipyard when an explosion rocked a section of the vessel around 9.15am following an apparent gas leak near an air-conditioned compartment.

The company’s natural gas production saw an increase of 4.2% during the quarter under review to 6.277 billion cubic meter (BCM) as against 6.025 bcm during the same quarter in 2016.

The nation’s top explorer, which planned to produce gas from a deep water block in the Krishna-Godavari basin off the country’s east coast from June 2019, won’t produce first gas until at least the second half of 2020, the people said, asking not to be identified because the information isn’t public.

In a regulatory filing, ONGC said it bought 778.8 million shares in Hindustan Petroleum Corp Ltd (HPCL) for Rs 473.97 per share.

"We are geared up to contributing towards achieving the PM's vision of reducing oil imports by 10% by 2022," the statement quoted Misra as saying. Misra is officiating as chairman in the absence of Shashi Shanker, who is in Davos as part of the Indian delegation to the World Economic Forum meet.

The borrowing is part of a tie-up with the three banks- Punjab National Bank (PNB), Bank of India (BOI) and Axis Bank, which took Rs. 18,060 crores for part funding its acquisition cost of Rs. 36,915 crore equity shares of the Hindustan Petroleum Corporation Limited (HPCL).
