24 October 2007 - Tullow Oil plc ('Tullow') announces that Rohan Courtney, the
Group's Senior Independent Director, and Chairman of the Audit Committee, is to
step down from the Board on 31 December 2007.



Mr. Courtney joined Tullow, and became chairman of the Audit Committee in 1993
when it was an Irish listed company and became Senior Independent Director in
2000.



Mr. Courtney's role as Chairman of the Audit Committee will be filled by David
Williams who joined the Board in 2006, and as Senior Independent Director by
Steven McTiernan who joined in 2002. The Nominations Committee of the Board
intends to appoint external advisors to commence a search to fill the vacancy
created by Mr. Courtney's resignation.



Mr. Courtney has agreed to remain on Tullow's Corporate and Social
Responsibility Committee and as a Trustee of one of the Tullow Group's pension
funds.



Commenting today, Pat Plunkett, Chairman of Tullow said:



'Rohan Courtney has played a very large part in Tullow's development and his
experience in banking and finance has been of immense assistance to Tullow
throughout his 14 year tenure.  Rohan joined the Board when Tullow had a market
capitalisation of £35 million and he has played an important role in each of the
key milestones in our history.



We thank him for his support of the business and management, his independence of
mind and constructive challenge to the Board and particularly his effective
Chairmanship of our Audit Committee through this critical phase of Tullow's
existence.  While Rohan is leaving our Board, I am very pleased he is not ending
his wider relationship with Tullow as he will remain on our CSR Committee and as
a Trustee of one of our pension funds.'
