Indago Petroleum announced that Indago Oman Limited , as operator for the Block 8 Joint Venture (comprising IOL 40%, Eagle Energy (Oman) Limited 10% and LG International Corporation 50%), has concluded testing operations onthe West Bukha-2A (WB2A) well, offshore Oman. Sustained production rates of 25MMscf/d and 8,364 bopd were achieved from the upper Ilam/Mishrif/Mauddud formation in the final test, complementing the flows of up to 4,392 bopddiscovered in the lower Thamama formation in the first test.
In a previous release on 21st November 2006 it was reported that the main target in WB2A, the Ilam/Mishrif/Mauddud, over a perforated interval of 60m spanning a depth from 4,005m to 4,127.5m (MDRKB), had been flowed at approximately 7,600 bbls/ d and 20.5 MMscf/d with a flowing tubing pressure ofaround 2,450 psia before surface and downhole equipment failures forced us to curtail the test. After repair and replacement of the equipment the test was conducted to a successful conclusion. The same interval was flowed at variousrates over the period from 5th to 10th December, including one for 15 hours on a choke setting of 72/64" which flowed at an average of 24.9 MMscf/d and 8364 bbls/d of 41.5o API oil, with a tubing pressure of 2,090 psia. By the end ofthat flow the water cut, resulting from the previous well kill and subsequent re-acidisation, had fallen to 3%, and no water was recorded during the final flow period.
These flows are additional to those recorded from the Thamama formation of up to 4,392 bbls/d of 42(degrees) API oil. Therefore the total combined rate from these two separate zones (Thamama plus Ilam/Mishrif/Mauddud) is 12,756 bopd and26.3 MMscf/d.
