Results, reports and presentations

With a strong balance sheet, robust production, planned portfolio activity to manage development capital and a set of industry-leading exploration basins and prospects, Tullow is well placed for the rest of the year and into 2014.

In 2012, Tullow delivered strong operating performance, enhanced our financial flexibility and expanded our portfolio for the next phase of growth.

2012 was a year of major progress for Tullow. We materially enhanced the business with a basin-opening oil discovery in Kenya, by adding highly prospective new licences in Africa and the Atlantic Margins, refinancing our debt and partially monetising our Ugandan assets.

Tullow Oil plc (Tullow) issues this Operational Update summarising key activities since the Interim Management Statement on 14 November 2012 and a Trading Statement in respect of its financial year to 31 December 2012. This is in advance of the Group’s Full Year Results, which are scheduled for release on Wednesday 13 February 2013. The information contained herein has not been audited and may be subject to further review.

Tullow had an excellent first half. The Group's strong financial performance was mainly driven by increased production, sustained high commodity prices and the profit on the Uganda farm down.

Developing new oil countries in Africa is transforming every aspect of our business and driving step changes in our responsibilities.
