Project Profile
Value: US$9.6 billion
Location: southeastern Wyoming
Reserves: 95 and 140 mmboe
Samson Oil & Gas entered into a joint venture to acquire acreage in the Hawk Springs project area, located in the Denver-Julesburg Basin in southeastern Wyoming. The venture holds approximately 144,000 acres and covers two prospective formations.
The Hawk Springs field is stratigraphically trapped. Similar geologic circumstances are present within the southwestern part of the project area where an isolated thick sequence of Codell Sandstone has been mapped using existing well control and therefore has the potential to generate a trap. While vintage exploration wells have penetrated this sequence and returned significant oil and gas shows, no commercial flow was established. However it has been the case that the early drilling and completion of the Wattenberg Field in the Codell was not successful and it was only in the very late 1990\'s that fracture stimulation technology enabled it to be exploited commercially. We believe that this trap has the potential to recover between 95 and 140 mmboe.
New exploration efforts in Hawk Springs have been focused on the Sharon Springs Member of the Pierre Shale Formation. The Pierre Shale was the main producing reservoir at Florence Field and Boulder Field along the Front Range to the south in the Colorado portion of the D-J Basin. These fields are located in a similar geologic setting along the Front Range as our Hawk Springs area. The Sharon Springs section of the Pierre was tested in the vertical portion of Samson\'s London Flats #1 well at a rate of 12 barrels of oil/day. Fractures within the Sharon Springs serve as the reservoir. Thus, a horizontal well would be beneficial by intersecting multiple sets of fractures within the Sharon Springs. Doing this may yield a well capable of producing several hundred barrels of oil per day.
