Dunn County, North Dakota Bakken Shale

By Tim - http://oilshalegas.com

November 8, 2011 - Kodiak Oil & Gas (KOG) recently gave an update on their Dunn County, North Dakota Bakken Shale and Three Forks Play. Kodiak Oil & Gas (KOG) is one of the up and coming exploration companies in the Bakken Shale due to their aggressive mineral rights leasing binge.

Kodiak’s five operated drilling rigs are presently drilling ahead on multi-well drilling pads. Three rigs are drilling in McKenzie County, and two rigs are drilling in Dunn County.

For the remainder of the fourth quarter 2011, Kodiak expects to complete or commence completion operations on an additional nine gross (6.1 net) operated wells, including two gross (0.8 net) wells from the recent acquisition. These operated wells are located on four drilling pads consisting of three, two-well pads and one, three-well pad. Drilling has been completed and operations are underway to construct surface equipment and pipelines on each of the pads. Currently, two gross (0.8 net) wells have been completed and are in flow-back operations. The remaining seven gross (6.6 net) wells are expected to commence completion operations during the remainder of the fourth quarter.

“We continue to make excellent wells in both Dunn and McKenzie Counties, which are integral to our production and cash flow growth trajectory we intend to provide our shareholders. One particularly positive development is the continued strong production profile from our first Three Forks well located in the McKenzie County Koala Project area. As shown above through the first 90 days of production, the well averaged nearly 1,000 BOE/d and is mirroring the offsetting Bakken well drilled just 700 feet away. With additional Three Forks production data, we can provide more accurate estimated ultimate recoveries for the Three Forks in the Koala area. We will also closely monitor the production profile from our two recent Dunn County Three Forks completions which have generated encouraging results.

Dunn County, North Dakota: Bakken Shale update

By Andrea: http://oilshalegas.com

ENSERVCO Corp. (ENSV.OB) recently released an update on the Bakken Shale in Dunn County, North Dakota.

ENSERVCO purchased several acres in Killdeer, North Dakota, and has entered into a construction contract on a new operations center. The facility is expected to be operational in September and will be located in the heart of the Williston Basin's Bakken Shale formation, one of the largest and most active oil fields in the continental United States.

ENSERVCO expects to break ground on the site later this week. At full operation, the facility will support 30 to 35 employees and a comparable number of service and construction vehicles. The facility will feature a maintenance shop and equipment yard, multiple offices and living quarters for up to 16 employees.

"Many of our current customers have established large acreage positions and extensive drilling programs in the Bakken," said Mike Herman, chairman and CEO. "ENSERVCO is an approved service provider to these companies in other major fields, and they have encouraged us to expand our operations into North Dakota."

Initial customers in the Bakken are expected to include EOG Resources and Hess Corporation (two of the largest oil producers in the Basin), Whiting Petroleum, Brigham Exploration and Chesapeake Energy.

Low average annual temperatures in North Dakota result in frac-fluid heating requirements that can extend eight to 10 months out of the year, according to ENSERVCO's customers. Many of these companies also have expressed a need for year-round well maintenance services such as hot oiling and acidizing, as well as well-site construction services.

"We believe our move into the Bakken could be as strategically significant as our successful expansion last year into the Marcellus Shale," Herman said.

ENSERVCO's North Dakota location will commence operations less than a month after the scheduled opening of its Niobrara Shale facility in Cheyenne, WY.

Dunn County, ND: Bakken Shale Update

By Andrea: http://oilshalegas.com

Kodiac Oil and Gas Corp. (KOG) recently released an update on their Bakken shale activity located in Dunn County, ND:

Kodiak will be mobilizing its third drilling rig in the Williston Basin within 30 days. Kodiak is also participating in one non-operated drilling rig with its joint venture partner in the Dunn County area of mutual interest. The joint venture partner recently reached total depth on its first two long-lateral middle Bakken wells and they are awaiting completion. Kodiak owns a 50% WI and 41% NRI in both wells and retains a comparable interest in all of the AMI lands. The Company has recently been notified that its joint venture partner intends to mobilize a second rig to the AMI in mid-year 2011.

Dunn County, ND: Bakken Shale Update

By Andrea: http://oilshalegas.com

Recently, Continental Resources Inc. (CLR) completed 4 wells located in Dunn County, ND:

Among Continental's operated wells completed in the third quarter of 2010 were the four wells in its first ECO-Pad(R) project - Hegler 1-13H and 2-13H (83% WI) and Arthur 1-12H and 2-12H (94% WI) in Dunn County. Continental's ECO-Pad concept involves drilling paired wells in adjoining 1,280-acre spacing units. The ECO-Pad concept involves drilling the first pair of parallel wells to target the Middle Bakken zone and the Three Forks zone in the first unit, separated vertically by about 50 feet and horizontally by 660 feet. The second pair of wells duplicates this pattern in the adjoining spacing unit.

All four wells are drilled from a single drilling pad, which reduces surface footprint. The Arthur and Hegler wells in the first ECO-Pad project had a one-day test production rate total of 4,359 Boe, for an average of 1,090 Boepd per well.

"Production rates and wellbore pressures clearly indicate that the Middle Bakken and Three Forks zones are isolated from one another, confirming our expanded view of the North Dakota Bakken's potential," Mr. Hamm said. "We are producing these wells under restriction to conserve the energy resource and minimize flaring.

"This is clearly the technology approach to take as we move into full-scale development," Mr. Hamm said.

Dunn County and McKenzie County, ND: Bakken Shale Update

By Andrea: http://oilshalegas.com

Recently, Enerplus Resources Fund (ERF) acquired 46,500 net acres in the Bakken Shale across Dunn and McKenzie County, ND. The acquisition includes roughly 800 bbls/day of light crude oil production and around 10 million BOE:

Building on our existing Bakken land base in North Dakota, Enerplus has entered into an agreement to acquire an additional 46,500 net acres (72 sections) of land in the Fort Berthold area of Dunn and McKenzie counties in North Dakota. These lands are directly adjacent to our existing land holdings in this area and are prospective for light crude oil in the Bakken and Three Forks formations. The acquisition materially expands our current position to over 70,000 net acres (109 sections) in the Fort Berthold area, the majority of which will be operated by Enerplus with a greater than 90% working interest. Enerplus has proven expertise in this area and recent drilling results have been above expectations. With this acquisition, we now have over 210,000 net acres of undeveloped land with early stage Bakken and Three Forks potential in North Dakota and Saskatchewan in addition to our core Bakken field at Sleeping Giant in Montana.

The acquisition includes approximately 800 bbls/day of light crude oil production and proved plus probable reserves of 10 million BOE primarily attributable to the Bakken formation based upon our internal evaluation. This compliments our existing estimate of eight million BOE of unbooked proved plus probable reserves in this area. The purchase price before closing adjustments is US$456 million and will be funded through Enerplus' existing credit facility. The acquisition is expected to close in October 2010.

Enerplus has been active in the Fort Berthold area since late 2009 and over the past year we have participated in the drilling of nine operated horizontal wells, six of which have been completed to date. The lateral length of these wells has ranged from 4,300 feet with 12 frac stages for the short lateral wells to 9,000 feet with 24 frac stages for the long lateral wells.



<<>>


Production from the long lateral wells has been limited due to fluid handling capacity.



Our internal assessment of the Bakken potential in this area is approximately five to six million barrels of original oil in place per section. Based upon a drilling density of two wells per section (two long lateral wells per 1,280 acres or two short lateral wells per 640 acres) with an approximate 15% recovery factor, we estimate an additional 50 million barrels of best estimate contingent resources on our combined working interest lands in the Fort Berthold area in addition to the 18 million BOE of proved plus probable reserves. We also believe the lands are prospective for the Three Forks formation for which we have estimated four to five million barrels of original oil in place per section. However, given the limited production data available, we are in the process of evaluating the potential recoveries and development opportunity that may exist in the Three Forks.

Bakken Shale: Dunn County North Dakota

Today, 1/8/09, Kodiak Oil & Gas ( KOG ) has come out and given an operational update on the Bakken Shale and the Sanish/Three Forks region on the Bakken Shale. They have acerage positions in Dunn County, North Dakota.

Williston Basin Operations Update -- Dunn County, North Dakota

Kodiak's exploration efforts target oil and gas production from the middle member between the upper and lower Bakken shales, which is the source rock for existing hydrocarbons. The Three Forks/Sanish Formation, a productive interval lying directly below the lower Bakken shale, is also expected to be a future exploration target. Commercial production from the Three Forks/Sanish Formation is being reported by operators in the immediate area.

The Moccasin Creek (MC) #16-34-2H well (Kodiak operates with 60% working interest [WI] and 49% net revenue interest [NRI]) recently reached total depth. The well, located in the southwestern portion of Kodiak's leasehold, was drilled to an approximate total vertical depth (TVD) of 10,350 feet and a total measured depth (TMD) of 15,525 feet. During drilling operations, the wellbore encountered oil and gas shows in the lateral. A liner was run to total depth and completion work is tentatively scheduled after drilling of the MC #16-34H well is finished. The well successfully reached TMD in 38 days, which is within the Company's initial estimate of 40 days to total depth.

The drilling rig has been skid approximately 50 feet where drilling recently commenced on the MC #16-34H well (Kodiak operates with 60% WI and 49% NRI). The MC #16-34H is projected to be drilled to a TVD of 10,350 feet and proposed TMD of 14,800 feet.
Six miles east of the Moccasin Creek wells, Kodiak has completed construction of a drilling pad for the Charging Eagle (CE) #1-22-15H and the CE #1-22-23H wells. Approximately 10 miles north of the Moccasin Creek locations, a second drill pad is being constructed for the Two Shield Butte (TSB) #16-8H and the TSB #16-8-16H wells. Kodiak operates both locations and will utilize the skid package on its rig to move between wells, minimizing mobilization time and surface disturbance. Upon completion of the MC #16-34H well, the drilling rig will be moved to one of these drilling pads.

As of January 1, 2009, Kodiak had approximately 56,000 gross and 36,000 net acres under lease on the Fort Berthoud Indian Reservation (FBIR). Kodiak operates all of its leasehold on the FBIR, with the exception of approximately 9,000 net acres that are in a participating area previously established with another operator.
