After 22 hours of continuous pumping and during the fourth phase of the stimulation program, an anomalous pressure drop was noted and the operations were suspended to allow further investigation. At this point, the first three phases had been completed with over 80% of the planned fluids for this stage being pumped with real time indicators of the stimulation.
After the investigation, the operator has elected to run a tie back string of 5½ inch casing from the top of the liner to surface. Thereafter, an isolation plug, which has been set in the liner as part of the investigation, will be removed and the well flowed to surface.
The fracture equipment has demobilised and a rig is now moving on to the location to carry out the work. It is presently estimated that the Kowalik-1H well will be flowed to production in one to two weeks.
The well site preparations have now started for the first farmin well at Sugarloaf, a Easley-1H well, which will be located approximately 2km to the north east of the Weston-1H well. This well is expected to be spudded during the month of January 2010.
