RIL's shale gas business in the US includes three upstream joint ventures with Chevron, Pioneer Natural Resource and Carrizo Oil and Gas. It had sold its midstream JV with Pioneer last June.
So far, RIL has invested a whopping USD 8.1 billion into these three entities.
"We have been scaling down our capex for the shale gas business. Going by the way the energy prices are behaving, there is no way we will be increasing our investment in this business. While last year we had invested over USD 1.2 billion, we have brought that down to USD 500 million this year.
But he was quick to add that the company does not see any more impairment charges for the US business in the fourth quarter nor had many such provisions in the December quarter.
Asked about whether RIL is looking at cashing out, he said going by the gas price, this is not the right time for a sale.
The average US shale realisation was down 50 per cent y-o-y to USD2.81/MCFe as of September quarter, the company said.
It spent Rs 81,463 crore in the first three quarters of 2015-16, mainly on account of ongoing expansions projects in the petrochemicals and refining business at Jamnagar, Dahej and Hazira, Jio Infocomm and also in US shale gas.
The decision follows a steep fall in energy prices across the globe on over-supply, coupled with environmental concerns in the US which led to many states banning shale gas projects, saying shale fracking contaminates ground water. Due to these factors, many companies are reducing their exposure to shale gas assets in that country.
RIL in June 2010 bought 45 per cent stake in Pioneer's Eagle Ford shale formation in south Texas for USD 1.31 billion and since then has invested USD 3.91 billion into the JV.
On June 2, 2015 RIL and Pioneer sold a part of its gas assets for USD 2.15 billion to Enterprise Products Partners, while choosing to retain the upstream business.
Reliance and Pioneer Natural sold the stake in Eagle Ford Shale Midstream as gas prices have nosedived.
