Press release here.
In 2013, the Company embarked on a
plan to test different areas across the Bakken field to determine what
well density and pattern best maximizes crude oil recovery and returns.
In all, the Company has initiated seven density pilot projects, all
designed to include the Middle Bakken and Three Forks One, Two
and Three ("TF1", "TF2", "TF3") across a broad section of Continental's
approximately 1.2 million net acres of leasehold. Three of these
projects are testing 1,320-foot inter-well spacing and four are testing
660-foot inter-well spacing. [I assume the "old" "upper Three Forks" is now TF1.]
The Hawkinson 1,320-foot pilot
project was the first to be completed by the Company and was announced
as a fourth quarter 2013 completion, followed by additional 1,320-foot
spacing tests at the Rollefstad and Tangsrud units. The Hawkinson pilot
continues to be a strong producer with all of the 14 wells trending on
average 50% above the Company's 603,000 Boe EUR model after 190 to 250
producing days.
The Rollefstad pilot is also performing well, with 10
of the 11 wells on the unit producing an average rate that is 10% above
the 603,000 Boe EUR model after approximately 60 producing days. Four
wells at the Rollefstad unit are still flowing naturally without the aid
of artificial lift.
The Tangsrud pilot was designed to test the extent
of the Lower Three Forks productive footprint in the northern portion
of the play. On average the MB and TF1 wells are producing similarly to
neighboring wells in the area. The TF2 and TF3 producers in the
Tangsrud pilot continue to underperform offset MB and TF1 producers and
do not appear to deliver economic results that compete with the
Company's substantial inventory of high rate-of-return development
opportunities, based on current technology and cost structure.
In late May 2014, the Company
began producing its first 660-foot inter-well spacing test at the
Wahpeton pilot in McKenzie County, North Dakota. The new wells were
completed using the Company's standard completion design of 30 stages
with 100,000 pounds of proppant per stage. Initial production rates for
the 12 new wells in the unit averaged approximately 1,015 Boe per day,
which included three new MB wells averaging approximately 1,730 Boe per
day.
Mr. Bott added, "Continental
continues to lead the industry in seeking the optimum density and
enhanced completions in order to maximize recovery, enhance returns and
increase net present value. It is too early to estimate recoveries at
the Wahpeton pilot; however, we are encouraged by the early performance
and potential for 660-foot inter-well spacing."
The three remaining pilot
projects are 660-foot inter-well spacing tests that are in various
stages of drilling or completion. These include the Mack, Lawrence and
Hartman units, which include a combined 18 new wells and six existing
producers. The new wells are expected to be completed in the second
half of 2014.
What's the Atlanta wells? Is that one of these density pilots?
ReplyDeleteAlso, would be interesting to see KOG, CLR, and any other pilots all described together.
Some information is posted here along that line:
