WesternZagros Resources has made an oil discovery in the Upper Fars Formation at the Mil Qasim-1 exploration well in the Kurdistan Region of Iraq.
Mil Qasim-1 Discovery Well (Garmian Block)
Lower Bakhtiari and Upper Fars Formations
Mil Qasim-1 was drilled to a total depth of 2,425 metres in December 2011 ahead of time and on budget. The well encountered a gross hydrocarbon bearing interval of approximately 800 metres containing numerous sandstones (each in the range of 2-13 metres thick) in the Lower Bakhtiari and Upper Fars Formations. Hydrocarbon shows and wireline logs indicate the presence of oil in the Upper Fars Formation and this was the focus of the testing program. Hydrocarbon shows and wireline logs also indicate the potential for additional oil in the Lower Bakhtiari Formation, but testing of this interval has been deferred to a later date.
The testing program has resulted in the flow of light, 43 to 44 degree API oil to surface from low permeability sandstone reservoirs and natural fractures in the Upper Fars Formation. No H2S and no formation water were identified during testing. Four tests were conducted in the Mil Qasim-1 well. Test 1 was an open hole test, Tests 2 to 4 were cased hole tests.
Test 1 was conducted over the open hole section between the depths of 2,129 metres and 2,168 metres. Test 1 resulted in a flow of 44 degree API gravity oil with no formation water, at an average rate of 108 barrels of oil per day ("bopd") over a two day period using an 8/64" choke with a flowing well head pressure of 1,606 psi. Initial reservoir pressure was calculated to be 6,405 psi.
