News and Updates, Parshall Oil Field In General

November 3, 2013: Mike Filloon on sand and fracking. 

July 14, 2013: Mike Filloon continues his analysis of the incredible Parshall oil field.

July 9, 2013: Mike Filloon updates the incredible Parshall oil field.

March 28, 2010: Update on Fertile Township, Parshall Oil Field, FBIR

March 25, 2010:  See EOG news below, dated March 15, 2010. EOG was granted two more permits for a section in the Parshall that already has a producing well: #18850 and #18767, in section 8-153N-90W. The first well was # 17127. The #17127 is in the NWNW corner; the #18767 is in the NENW corner; and, the #18850 is in the SWSE corner. The #17127 had an IP of almost 2,000 bopd. The names of the three wells: Wayzetta 11-08H; Wayzetta 108-08H; and, Wayzetta 129-08H.

March 21, 2010: Update on Fertile Township, Parshall Oil Field, FBIR

March 15, 2010: This blog was one of the first by an armchair amateur, if not the first, to point out that EOG plans to drill three wells in almost every section in the Parshall. It's starting:  EOG was granted two permits, both in section 30, 153-90. There is already a producing well in that section (17129, IP - 610), and all adjoining sections have producing wells. Are these two more Middle Bakken (MB) wells? Unlikely. More likely an Upper TFS well and a Lower TFS well.

March 2, 2010: There is a backlog of wells that still need to be fracked in Fertile township.

The Parshall Oil Field

AAPG Foundation on Michael S Johnson, contributions to discovering the Parshall oil field. 

Wiki.

The Parshall oil field is one of two of the most prolific oil fields in the Bakken play in the current boom; the other is the Sanish oil field. The field is "owned" by EOG.

Michael Johnson is credited with discovering the Parshall oil field after comparing the geologic fingerprint of the highly productive Elm Coulee field in Montana with geologic fingerprint of the area in the area around Stanley, ND. Mr Johnson was honored as the 2009 AAPG Explorer of the Year for this discovery. (AAPG member Dick Findley received the 2006 AAPG Explorer of the Year honor for the Elm Coulee discovery, discovered in the 1990's. For more on Richard Findley, see this 2008 Seeking Alpha article -- absolutely prescient.)

EOG's discovery well in the Parshall was drilled in 2006: Parshall 1-36H, #16164; the lateral was about half the distance of present day "short laterals." Pressures were so high in that initial well, that it blew out when the bit was 1,200 feet into the Middle Bakken; it eventually settled down to 460 bopd.

The Parshall oil field is a rectangular field, with four townships running north to south, with a few sections from adjoining townships on the west and east. The southernmost township, Fertile township, is entirely within the Fort Berthold Indian Reservation. Due to bureaucratic necessities, the development of oil activity was delayed in the reservation but is now catching up. (By the way, this will benefit EOG, KOG, and Slawson, as well as others.)

There are 211 sections in the Parshall oil field, and it appears that a few sections will likely be added to this oil field in the near future. The town of Parshall is located in Parshall township, the third township down (counting from top to bottom), and is inside the reservation. The population of Parshall was 981 in the 2000 census according to Wikipedia.  Something tells me it's a bit bigger these days. (Quiz: what are the names of the three tribes that make up the Three Affiliated Tribes in the FBIR? Answer at end of posting.)

Of the four main townships, again running north to south, the southernmost is perhaps the most active right now, but again that was due to bureaucratic delays. Townships 1, 2, and 3 pretty much have one well in each section, whereas township 4, has only nine (9) producing wells but is very active.

By township, north to south (as of June 8, 2010):

Township #1 Austin township, 154-90, the northernmost: 36 producing wells; 3 confidential; one being drilled.
Township #2, Wayzetta township, 153-90: 38 producing wells, 0 rigs on site, 5 confidential, 1 drilling.
Township #3, Parshall township, 152-90: 38 producing wells, 0 confidential. Most of the sections are inside the reservation.
Township #4, Fertile township, 151-90, the southernmost: 14 producing wells, 5 wells being drilled, 0 sections with rigs on site, 5 confidential, and 5 permits with no activity yet. All sections are within the reservation.

The remaining sections (67) in the adjoining townships have 45 producing wells, 6 confidential, 0 drilling, and 0 rig on site.

How productive has the Parshall oil field been to date (Feb 2010)? Austin Township, 154-90,  has 35 wells that, to date, have each averaged $18,047,922 at the wellhead. The township has generated $630 million, so far, at the wellhead and is currently adding over $30 million to its total gross revenue each month, according to "Larry," at Bakken Shale Discussion Groups, February 28, 2010.

Answer to quiz: the Three Affiliated Tribes are the Mandan, Hidatsa and Arikara Nation.
