ECO-PADS
January 14, 2018: re-posting a link to Rigzone story on CLR's Eco-Pads, August 6, 2009.
August 12, 2011: Update on three CLR Eco-Pads.
March 23, 2011: Nice story in Minot Daily News.com on Eco-Pads. Seven Eco-Pads completed so far; three more under development, more to follow. $6 million/well = $24 million/pad.
February 17, 2011: QEP has an Eco-Pad? First time I've seen another producer with four wells on one pad.
November 26, 2010: Update on CLR's Eco-Pads; eight wells on one pad; EUR for two 1280-acre spacing units with eight wells --> 4 million bbls. Four wells on one pad; two adjoining pads. EUR about one million barrels/section in better Bakken locations.
September 30, 2010: Three of four of the Arthur-Hegler Eco-Pad wells reported today.
September 13, 2010: CLR granted another Eco-Pad permit; this time in the same section whey CLR proved that the TFS and the Bakken are separate formations. Very, very exciting.
August 27, 2010: first Eco-Pad comes off confidential list tomorrow (August 28, 2010)
May 11, 2010: Rattlesnake Eco-Pad (Bridger/Bonneville); NENW 23-146N-96W
March 26, 2010: Eco-Pad permitted in Dunn County, SESW 26-147N-96W
Four wells #18858, #18859, #18860, #18861Update: CLR's first Eco-Pad has been spudded. March 3, 2010.

This is the definition of Eco-Pad as provided by reliable source at that site:
One Eco-Pad contains 4 wells. A Bakken and Three Forks well will be drilled both North and South from the Eco-Pad. This covers 4 square miles or 2,560 acres (4x640). I have noticed in their diagrams a placing of Eco-Pads on the far West and East sides of the stacked 2560 acres. This looks to me as if they want to drill 1 Eco-Pad on one side or the other and then if warranted drill another on the opposite side. If things look really good they will then have the possibility of placing a wells right in the center. If they complete the whole project there would then be a total of 12 wells.To see a graphic of an Eco-Pad, visit Continental Resources homepage for investors, and click on any of the recent corporate presentations. Somewhere around "slide 16" in the most recent presentations, CLR provides a graphic representation of an Eco-Pad. Pretty cool.
My opinion is the number of Eco-Pads placed in the 2,560 will be determined by how productive each Eco-Pad is. Since the productivity is variable then I would expect more Eco-Pads in some locations and fewer Eco-Pads in other locations.

February 18, 2010: Multi-well pads for Hess.
Hess granted permits #18733 and 18734, EN-Will Trust A-157-94-2734H-2 and EN-Will Trust A-157-94-2734H-3, respectively. These two wells are on the same pad, 25 feet away from each other. I am waiting to see a permit for EN-Will Trust A-157-94-2734H-1. They are in the Big Butte oil field, Mountrail County.January 25, 2010: Hess' multiple-well pad concept. Six wells in one section, 2580-acre spacing.
January 21, 2010: CLR says it will drill 24 wells along the Williams-Divide county borders using the EcoPad concept. They will drill eight (8) wells on just 14 acres of land; four (4) wells on each pad, with the two pads abutting each other. Regulators have to approve the CLR proposal. Most interesting: the wells will be offset 50 feet from the section line, rather than the customary 500 feet. This will add 450 feet per lateral per well that would normally go undeveloped. The article is in the Tioga-Crosby Journal online.
