Sonde Resources Announces Test Results from Its Zarat North-1 Appraisal Well, Offshore Tunisia

Sonde Resources Corp. announced today that it has completed drilling and production testing of its inaugural well on the 7th of November Block, offshore Tunisia / Libya, the Zarat North-1 appraisal, in which Sonde owns a 100% working interest.

Jack Schanck, Sonde’s President and CEO, said “We are very pleased with the robust test results from this well, and the thickness of the hydrocarbon column, which was about twice that originally estimated for this location. Our near-term engineering studies will include reviewing the use of horizontal wells for developing the field, which may result in significantly higher production rates and recoverable reserves per well given the high quality of reservoir rock encountered.”

Drilled vertically to a depth of 9,728 feet, the Well encountered 240 net feet of pay in the Eocene El Gueria limestone. The Well was cased to total depth and three production tests were performed through 2 ¼” diameter test string, from 42 feet above the water contact to 177 feet above the water contact.All three tests flowed substantial quantities of gas and condensate, with Test 2 observing sustained ratesapproximately750 barrels of condensate and8 million cubic feet of gas per day and peak condensate rates as high as 1,100 barrels per day. Tests 1 and 3 observed sustained rates of approximately 600 barrels of condensate per day and gas ranging from 8 – 11.5 million cubic feet of gas per day. All tests produced water ranging from 200-350 barrels per day, which included both drilling fluids and formation water; water was decreasing and oil increasing throughout the tests. Sonde is actively assessing test data to determine key reservoir characteristics including porosity, permeability, water saturation and gas composition.

Located 2 kilometers (1.25 miles) northeast of the Marathon Zarat-1 discovery and 3 km (1.9 miles) northeast of the Zarat-2 appraisal, the Well encountered gas / oil and oil / water contacts at the same structural elevation as the Marathon wells, confirms a significantextension to the previously-proven accumulation, and suggests that an economically-viable, near-term development may be possible. By comparison with Sonde’s results, the Marathon Zarat-1 well observed rates of 457 barrels of condensate plus 5.3 million cubic feet of gas per day in a first test, and 1,181 barrels of condensate plus 15.1 million cubic feet of gas per day in a second test.

Management is reviewing recoverable reserve scenarios, development options and cost estimates for development of the Zarat field, andwill investigate unitization optionswith PA Resources, which holds a portion of the field immediately to the south of the 7th of November Block. In addition, Sonde is studying development financing and monetization options, including selling interests to one or more potential partners for the project.

Sonde will temporarily abandon the Well in a manner allowing it to be utilized for future development purposes.

Sonde Resources Corp. is a Calgary, Alberta, Canada based diversified global energy company engaged in the exploration and production of oil and natural gas and in the development of a liquefied natural gas (“LNG”) project. Its operations are located in Western Canada, offshore Trinidad and Tobago and North Africa.
