Samson Oil & Gas Offers Update On Operations In Montana, Wyoming

Frontier Drilling’s Rig #11

New Frontier Drilling rig contracted for 18 months.

    Samson Oil And Gas issued a press release on Tuesday updating their operations in Montana and Wyoming.



Gretel II 12KA 3 #1-30H

The Gretel II fracture stimulation is scheduled to commence March 25th. This frac job will be conducted in 20 stages and is in the final phase of design, with both the experience in Australia II and the geotechnical data from the cores recovered from the Bakken Formation being used to facilitate the design.

Australia II 12KA 6, #1-29H

A work-over rig is currently over the Australia II well and is preparing for the fishing of the perforation gun that was left in the hole. The work-over will then drill out the remaining frac plugs. Following that clean out operation, a completion string will be run.

Abercrombie 1-10H

The Abercrombie well has reached a total measured depth of 18,682 feet and a 29-stage production liner has been run. Samson and its partner FPEC have elected into this well to the extent of a combined 1.125% equity. Of this, Samson has a 2/3rds interest, or 0.75%. The Samson-FPEC interest derives from leases that FPEC and Samson own at the northern extent of the spacing unit.

The surface location is 4 miles south of the Gretel II surface location and the bottom hole location is approximately 1 mile south of the Gretel II bottom hole location. Therefore, this will be an important data point in the evaluation of the western part of the Roosevelt Project area.

Riva Ridge 6-7-33-56H

By virtue of its commercial relationship with Fort Peck Energy Company, Samson will be participating in the Riva Ridge well to be drilled in Sheridan County, Montana, several townships (T 56E, R 33N Section 6 and 7) to the north of Samson’s existing acreage holding. Samson’s participation in the Riva Ridge well has the potential to lower the risk involved in Samson’s Bakken play inside the Fort Peck Indian reservation. The well is proposed as a 10,000 foot lateral in the middle Bakken Formation.


Defender US33 #2-29H

Having achieved a pump rate of 288 BOPD the pump installed in the Defender well subsequently lost efficiency and the rate declined to zero BOPD. This pump has now been pulled and replaced. Examination of the two previously failed pumps has revealed an accumulation of sand and other debris in the pump, which has resulted in the loss of sealing ability of the standing and travelling valves in the pump.

Assessing the production performance of the well, it appears that, as the hydrostatic pressure is lowered because of the removal of produced fluids from the well bore, the well experiences a significant level of gas production which not only disturbs the valve placement, but injects debris into the pump.

The bottom hole configuration of the replacement pump has been changed, to combat this debris inflow, and pressure control will be applied at the surface to attempt to keep the gas in solution at the pump. This control and the choke settings on the annulus are being varied to obtain an optimum pumping configuration.

Discussion with other operators in the Niobrara suggests that gas related pumping issues are a common problem in the play.

Oil production rates have varied between 120 to 170 BOPD in the last 72 hours.


Samson has entered into two contracts with Frontier Drilling.

Frontier Rig 24 has been contracted for an 18 month period to drill wells in both the Roosevelt Project and in Samson’s North Dakota North Stockyard Field. Frontier 24 is a new build rig which is due to be completed in May/June 2012 and will drill one well before starting the Samson contract. The rig is a 1,500 horsepower, diesel electric, rig equipped with a top drive. The rig is mounted on a box on box substructure and is capable of being skidded between wells on a single “Eco Pad.” This design will allow Samson to batch drill four wells from a single drill pad which will provide significant mobilization savings.

Samson has also contracted Frontier Rig 11 to drill the Spirit of America II well in Goshen County Wyoming. The rig is a 1,000 horsepower, diesel electric rig equipped with a top drive. This well is planned as an 11,000 ft. vertical well to assess the Permian and Pennsylvanian aged targets that have been mapped from the 3D seismic acquired as part of the Hawk Springs project. The drilling engineering plan for this well has been extensively revised since the Spirit of America I was drilled and will use a combination of an oil-based mud, higher density mud and deeper set casing to combat the shale problem previously encountered above the target zone.

The contract for Rig 11 is for one firm well but would be available to drill the next Niobrara lateral in the event that our farminee elected to drill that well.

While the timing may be affected by the existing drilling activities associated with Rig 11, and the issuance of a drilling permit, Spirit of America II is presently expected to spud in the first half of April.

After my first job at a newspaper -- delivering papers for the Jackson (TN) Sun, ink was in my veins. Since the 1970's I've worked in every area of the Printing and Publishing industry, with most of that time spent in the pressroom. In 2008 I moved to Montana and purchased the Sun Times of Fairfield ( In 2011 I realized that most media outlets were either ignoring, or attacking, the growing oil and gas industry in Montana, so I started the Montana Oil Report as the source of information on this important industry.

  1. I have Interest in the Australia II well from my Mother Clara Small but have not received any Royalties as of todays date 9/20/2012! Would like 2 know what is going on! Or do we need 2 hire an Attorney!!
