Melrose Resources has finalised a sale of its last American assets.
The Edinburgh company is selling a gas field in Texas to Faulconer Resources for around £3.7 million.
Melrose is planning to concentrate more on drilling and exploration in the coming years.
David Thomas, chief executive, said: "We are pleased to complete the sale of our remaining gas leases in South East Texas which effectively concludes the divestment of Melrose's US asset portfolio.
"We can now fully focus the company's resources on our established core areas in Egypt and the Black Sea and on business development opportunities in areas where we have competitive advantages."
