Indian energy company Reliance Industries has broken off talks with Chesapeake Energy over a stake in the U.S. company's position in the Eagle Ford shale in south Texas, according to sources familiar with the matter. Chesapeake has been looking for a partner for its 600,000 acre position in the Eagle Ford. It said in May that it intended to close the deal by the end of the third quarter, but has since pushed the deadline back slightly. Reuters reported last month that the two companies were in talks over the Eagle Ford position, citing a source with direct knowledge of the matter.
