Congress and exhibition also provided an opportunity to gain information and understanding of various African oil and gas projects.



  • 3D seismic data is being acquired over  an area of 300 km2 including the CS-10/10A and CS-11 wells. The data will be used to refine the structural closure to allow detailed reservoir interpretation and to identify additional potential areas. The survey started in the second half of 2013 and is expected to be completed, processed and interpreted in the coming months. A new well based on the results of the 3D survey is planned to be drilled later in 2014.


  • The International Geophysical Congress and Exhibition of Turkey was held in Antalya between 25-27 November, under the sponsorship of Petoil.



Chia Surkh-11 well was drilled successfully, within the scope of the Chia Surkh Block Production Sharing Contract between Kurdistan Regional Government of Iraq, Petoil and Genel Energy, to 1912,5 meter depth in 2013. The operator of the Block is Genel Energy. Testing of the well has been completed with encouraging results. CS-11 was drilled 85m down-dip and 3km to the northwest of CS-10 and intersected a 170m gross hydrocarbon column in Miocene and Oligocene aged reservoirs.The Miocene Jeribe formation previously tested in CS-10 has flowed at a cumulative rate of 3,550bpd of 50 degree API oil and 21mmscfd of gas per day from two separate zones. The deeper Miocene Dhiban dolomite not penetrated in CS-10 flowed 2,060bpd of 50 degree API oil and 16mmscfd of gas. The Oligocene Euphrates formation not previously penetrated in CS-10 flowed 1,600bpd of 47 degree API oil and 9mmscfd of gas.

MAY 2013

Chia Surkh-10/10A well was drilled successfully, within the scope of the Chia Surkh Block Production Sharing Contract between Kurdistan Regional Government of Iraq, Petoil and Genel Energy, to 1696 meter depth and well testing has been completed within the months of March and April 2013. The operator of the Block is Genel Energy. Drill stem test conducted in a Jeribe Formation interval flowed at up to 11,950 barrels oil and 15 million cubic feet of gas per day. The gravity of the oil was 41o API. A second test carried out over a 12 meter zone in a younger Miocene section flowed at sustained rates of 3200 barrels of oil and 8,4 million cubic feet of gas per day.
