The company said that Mr Hickey’s decision to leave Tullow reflects the considerable personal demands of his role in a London-based multi-national company and his desire to live full time in Ireland.
Mr Hickey will remain in his role until a suitable candidate has been identified to ensure an orderly transition.
Aidan Heavey, CEO of Tullow Oil, said: I am personally very sad that Tom is to leave Tullow as he has made an outstanding contribution to the group since he joined us in 2000. His commitment has been exceptional and we are all truly disappointed that he will not be part of the next phase of growth and development of the business.
