ShaMaran Petroleum has successfully tested oil at Chiya Khere-5 development well in Kurdistan Region of Iraq’s Atrush Block
The Chiya Khere-5 development well was drilled and suspended last year. The well was re-entered in May 2015 and three well tests (DST) using an electrical submersible pump were carried out.
DST#1 was conducted over a 24-metre interval in the Mus Formation. The interval tested at an average oil rate of 750 bpd with a final water cut of less than one per cent. Oil gravity was measured at 16º API.
DST#2 was conducted through 60 metres of perforations within a 118-metre interval in the Sargelu Formation. The interval tested at an average oil rate of 5,000 bpd with a constrained drawdown during the main test period. There was no water cut at the end of the test. Oil gravity was measured at approximately 25º API.
DST#3 was conducted over a perforated 12-metre interval within the Naokelekan Formation. The interval tested at an average rate of 1,600 bpd with a measured oil gravity similar to DST#2.
The work-over rig has now moved to the adjacent CK-8 development well and commenced testing operations.
Chris Bruijnzeels, CEO of ShaMaran Petroleum, said, “The CK-5 well test results are in line with expectations and confirm excellent well productivities. We estimate that the CK-5 well can produce in excess of 10,000 bpd. Combined with the AT-2 and AT-4 well test results, I am confident that we are on track to produce at our planned Phase I production level of 30,000 bpd from four wells, including CK-8.”
The Atrush Block is operated by TAQA, which holds 39.9 per cent stake. ShaMaran Petroleum owns 20.1 per cent through its wholly-owned subsidiary General Exploration Partners.
Marathon Oil and Kurdistan Regional Government hold 15 per cent and 25 per cent stake respectively.
