Coastal Energy Company announced the successful Miocene discovery in the Bua Ban South A-04 well.
The Bua Ban South A-04 well was drilled to a depth of 3,250 feet TVD on the eastern flank fault block at Bua Ban South, approximately 1.5 miles south of the Bua Ban Main A-11 well. The A-04 well encountered 42 feet of net pay in the Lower Miocene M75 and M100 sands with 29.5% average porosity. The M75 is a newly discovered pay sand in the Lower Miocene. Initial results indicate that this is an extension of the Miocene reservoir which was encountered in the Bua Ban Main A-11. The A-11 well has been producing since September 2010 and is currently producing over 500 bopd. The minimum areal extent of the closure is approximately 550 acres.
Randy Bartley, President & Chief Executive Officer, commented, "We are greatly encouraged by the successful Miocene results in the A-04 well. We have now discovered oil in three different Miocene intervals between Bua Ban Main and Bua Ban South. This new discovery is very positive for the Miocene remaining potential across the entire basin as well as supporting the potential of recent Oligocene discoveries in the Bua Ban South area.
"The Bua Ban South A-03ST#1 well has been spudded and will test the Eocene objective. We are currently evaluating locations for Miocene appraisal wells and will begin drilling those following the A-03ST#1."
