Treating pressures observed and log data collected since the fracture stimulation suggest that several different fracture areas were created. Following a series of evaluation operations, the well has been placed on pump and has recovered most of the 2,500 barrels of stimulation fluids.
The current flow rate is 300 barrels of oil per day (bopd) representing an oil cut of 60% which is equivalent to the oil cut pre-stimulation. This rate is likely to be increased in the short term by replacing the existing pump with a higher capacity pump.
The well is producing at a rate of 300bopd from a 4,800 foot horizontal well bore, the same well bore and producing interval that produced the pre-stimulation rate of 68bopd. The well is not cased over the productive section and is producing from a dolomitic limestone.
The Harstad well is located in the Williston Basin in North Dakota and produces from the Bluell formation, which is developed in this field using horizontal completions. Samson’s working interest in the Harstad well is 34.5%. Due to ownership difference across the leased area, Samson’s total working interest in the prospect is 41%.
