Talks a few merger involving Tullow Oil, the London-listed African oil explorer, and Meren Power, a Canadian-listed peer, have collapsed.
It was unclear on Tuesday night what the rationale was for the abandonment of the negotiations.
Tullow Oil, which has a market valuation of about £275m, is concentrated on West-African producing property in Ghana, Gabon and the Ivory Coast.
The corporate has seen its inventory plunge dramatically since its peak valuation of about £15bn.
Final December, it noticed merger talks involving Kosmos Power crumble.

Meren Power, which till lately was referred to as Africa Oil Corp, is considerably bigger than Tullow Oil in valuation phrases.
Listed in Canada and Sweden, it has a market capitalisation equal to roughly £980m.
Run by chief govt Roger Tucker, Meren lately stated it had as much as $500m to spend on buying producing property in Africa.
A spokesman for Tullow Oil declined to remark.
