Operating Update Egypt

Circle Oil Plc (AIM: COP), the international oil and gas exploration, development and production company, is pleased to announce the following update regarding the Al Amir SE Field ("AASE") and the Geyad Field in Egypt.

AASE-18 Well

AASE-18 was spud on 7 July 2013 and is located in the north-western part of the AASE. The well's objective was to appraise both the Shagar and Rahmi sands, and for Rahmi sand water injection at that location to support the updip producers. The well encountered the Kareem sands over 200 feet high to prognosis with 34 feet of net pay in the Shagar and 32 feet of net pay in the Rahmi, both zones of good reservoir quality. Following successful logging, the well is now planned to be tested and completed as a Rahmi producer and the test results will be provided in due course.

AASE-6X Well

AASE-6X was recompleted as a Rahmi producer on 30 July 2013 and placed on production at a daily rate of 700 bopd and 0.637 MMscf/d on a 32/64" choke.

Shehab-2 Well

The Shehab-2 exploration well located approximately 2 kilometres north of the Geyad Field was spud on 19 June 2013 and found the target Kareem sands to be water bearing. However, this well encountered a potential gas bearing interval in the Upper Rudeis limestones from 5,220.5 to 5,235 feet MD and following logging a hydraulic fracturation was completed on 30 July 2013. The test was unsuccessful with no flow to surface and the well has now been temporarily abandoned whilst alternative stimulation options are considered.

Production

The current gross daily production rate from the AASE and the Geyad Field is now standing at 11,227 bopd and 12.3 MMscf/d (2,238 boepd). Cumulative production from the NW Gemsa Concession has now exceeded 12.3 million barrels of 42 degree API crude oil.

Water Injection

Water injection in the AASE and Geyad Field is currently about 26,790 bwpd and the cumulative injection to date is about 12.5 MMbw.

The NW Gemsa Concession, containing the Al Amir and Geyad Development Leases, covering an area of over 260 square kilometres, lies about 300 kilometres southeast of Cairo in a partially unexplored area of the Gulf of Suez Basin.

The concession agreement included the right of conversion to a production licence of 20 years, plus extensions, in the event of commercial discoveries. The NW Gemsa Concession partners include: Vegas Oil and Gas (50% interest and operator); Circle Oil Plc (40% interest); and Sea Dragon Energy (10% interest).

Prof Chris Green, CEO, said

"Circle is very pleased with the results of the AASE-18 well, which will provide additional oil and gas production from the Al Amir SE field. In addition, the recompletion of AASE-6X for Rahmi production has resulted in a further increase in the total gross daily production to over 13,000 boepd."

Notes to Editors

Circle Oil Plc (AIM: COP) is an international oil & gas exploration, development and production Company holding a portfolio of assets in Morocco, Tunisia, Oman, and Egypt with a combination of low-risk, near-term production, and significant upside exploration potential. The Company listed on AIM in October 2004.

Internationally, the Company has continued to expand its portfolio over the past years and now has assets in the Rharb Basin, Morocco; the Ras Marmour Permit in southern Tunisia; the Mahdia Permit offshore Tunisia, and the Zeit Bay area of Egypt. Circle also has the largest licensed acreage of any company in Oman. In addition to its prospective Block 52 offshore, Circle has an ongoing exploration programme in Block 49 onshore.

Circle's strategy is to locate and secure additional licences in prospective hydrocarbon provinces and, through targeted investment programmes, monetise the value in those assets for the benefit of shareholders. This could be achieved through farm-outs to selected partners who would then invest in and continue the development of the asset into production, or Circle may opt to use its own expertise to appraise reserves and bring assets into production, generating sustained cash flow for further investment.
