Samson Oil & Gas to Drill a Bakken Formation Well in North Dakota

Samson Oil & Gas currently produces around 100 BOPD (gross) from a horizontal well placed in the Bluell Formation of the North Harstad oil field which is located in the central part of the Williston Basin. This well has been on production for 15 months and has demonstrated the productive capacity of this formation such that development wells adjacent to this location are being planned as part of Samson’s effort to enlarge its oil production profile to take advantage of the exceptional oil price that is currently in effect.

In addition to this Bluell activity Samson has received a proposal from the operator of the field to drill a Bakken Formation well. This well is proposed to be drilled to a vertical depth of 11,335 feet, plugged back and then drilled horizontally for 4,800 feet in the middle Bakken zone. The Bakken zone is planned to be stimulated using state-of-the-art technology which will include external casing packers such that the well is stimulated along its entire horizontal length. Samson has 50% equity in the well and is looking to reduce this equity by way of farmout where it would retain 31.25% equity in the well. Samson’s participation in this well will depend on the successful marketing of this property which is now underway.

The well is expected to spud mid-August, subject to rig availability. The current United States Geologic Survey (USGS) assessment for Bakken contingent reserves within the Central Basin where this field is located is 485 million barrels of oil and 246 billion cubic feet of gas (Mean reserves). Current production from the Bakken in just the North Dakota portion of the Williston Basin was 6,200 barrels of oil per day and 30 million cubic feet of gas per day for the month of May 2008 from 88 wells.

Using data from a leading service company’s case study, Samson’s North Harstad leased area could contain a contingent recoverable oil volume of 7.7 million barrels of oil from the Bakken of which 3.2 million barrels would be net to Samson.
