Record IP In The Williston Basin

Question 9 from the FAQ page (note: this page may not always be updated. I am likely to update this on the FAQ page).

What is the record IP to date in the Williston Basin? 
From a November 11, 2014, post (see also the November 25, 2014, post, same subject); The first well, in the Middle Bakken formation, was completed with 94 stages and was flowing 7,120 BOE/d on October 10, 2014, according to the operator. When the well was completed, it established a world record for number of stages in a single well.
Soon after, an offset well in the Upper Three Forks formation was completed with 104 stages. This well was flowing 7,824 BOE/d on October 11, 2014. This was a hybrid completion comprising 97 NCS GripShift cemented casing sleeves, with seven NCS BallShift cemented ball-drop sleeves in the lower section of the well. In both wells, all stages were successfully fractured.
More to follow: in 2Q14 earnings report, WLL: Tarpon Well Completed in 2nd Bench of Three Forks Flowing 6,071 boepd. Not a record in the Bakken -- see Statoil's #23992. But still, this is huge for the second bench.
Statoil reported an IP of 5,417 on September 26, 2013: #23992, Beaux 18-19 7H, Banks oil field. Based on its IP for natural gas (9,663), this well had an IP of 7,083 boepd
Statoil reported an IP of 5,387 on July 19, 2013: #23387, Beaux 18-19 4H, Banks oil field. This might be a new record (this is the IP for crude oil only).
The initial production of any well, self-reported by the producer, is becoming less meaningful over time. Having said that, it looks like the record IP for a Bakken well is now 5,200a Newfield well (July, 2011): 18691, 5,200, NFX, Wisness Federal 152-96-4-2H, Westberg, Bakken.
Statoil reported on July 10, 2013: 23385, 5,070, Beaux 18-19 6H, Banks, t6/13; cum -- ; 7 days to drill the lateral; I did not see completion data; 31 swell packers planned; 
Two earlier wells: a Whiting well which had an IP of 4,761 boepd: file #17612, 4,761 boepd IP, Whiting, Maki 11-27H, Mountrail County, Sanish field.  This is still current as of February 20, 2010. Since then, BEXP claims to have set a record with the Sorenson 29-32 1-H, #18654, with a 24-hour flowback of 5,133 bopd. However, the NDIC reported an IP of 2,944. BEXP also reported the Jack Cvancara 19-18 #1H (this site is down) in the Ross project area with a 24-hour flowback of 5,035.
New record in the Bakken, November 3, 2011The Tarpon Federal 21-4H is a Whiting  Petroleum operated well and had a 24-hour initial production (IP) rate of 7,009 barrels of oil equivalent (BOE), setting a new Williston Basin record for a Bakken well.
Whiting said this was a record TFS well at the time, early 2012, file #20526, Smith 34-12TFH, 2,446, 102K in first 4.5 months.
