Sound Oil confirmed a leadership reshuffle after two of its senior leaders stepped down.
Andrew Hockey and Gerry Orbell have both left their director positions.
They will be replaced by Richard Liddel and Stephen Whyte.
Chairman Simon Davies said: “I am delighted to welcome Richard and Stephen to the board of Sound Oil. The wealth and breadth of their combined experience and connections will be of great value to the company as it prepares for further growth.
“I would also like to thank both Andrew and Gerry for their valuable contribution to the company over many years. Andrew has played a critical role in building the foundations of our Mediterranean gas business and we wish him continued success with his future endeavours. We are also extremely grateful to Gerry who, as the founding executive chairman of the company, and latterly as a non-executive director, has made a significant contribution to the development of Sound Oil.”
