Shale Gas:
BPRL entered into the arena of Shale Gas in 2010 with acquisition of interest in a block with shale gas potential in the Perth basin in Australia. A well has been drilled in this block and core results are positive. As of mid September 2012, hydraulic fracturing of this well is over, with hydrocarbon shows in all the five targeted zones. Initial flowback results are encouraging

Investments:
As of mid September 2012, BPRL has invested over USD 800 MM for its projects, with commitments in excess of USD 1.5 billion. The total cumulative outlay till end 2015-16 is to the tune of USD 2.2 billion.

I think they will be okay on the funds (cash) to test.
