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.
Updated: January 25, 2010
Not to know CLR's Ecopad, but another operator is beginning to use a 6 well pad that will have 12 producing laterals in it. They will drill 3 wells on a 1280 to the North / East and 3 wells on a 1280 to the South / West. Each of these wells will have a stacked lateral with one in the Three Forks and one in the Middle Bakken in a single vertical well bore. Also Baker Hughes has a pretty amazing new whipstock called the Frac Hook that allows fracing these wellbores back to back without having to pull a packer or the frac string. That coupled with the 24 - 28 stage sliding sleeve shall be interesting. This should prove whether these to formations are separate relatively soon.
ReplyDeleteThank you for stopping by. Absolutely incredible, what you just reported. A lot of folks will appreciate your input. It's hard to get first-hand reports and they are much appreciated.
ReplyDeleteOf the many things that impress me about "the Bakken," I think what impresses me most is the speed with which these producers are incorporating new techniques.
Slawson has been putting two wells on each pad for awhile now; it seems only logical in hindsight to maximize a pad, but hindsight is 20/20.
Again, thank you for your input.
The individual who first commented on six wells on one pad (above) did not mention the operator. It appears the operator is Hess. Note that of each set of three wells, one lateral is in the Middle Bakken, one is in the Three Forks Sanish, and one is a vertical borewell.
ReplyDeleteI was checking the Scout Ticket information last night on the Ron Viall saw that they have added a couple of 'Side Tracks' with different coordinates all going north like the first lateral. Is this an indication of a Eco-Pad? I haven't seen any clear request in the Dockets so I was wonder how to find out more about this information.
ReplyDeleteEco-Pad is a copyright that belongs to CLR. The Ron Viall is an AEZ well and I don't think CLR was involved (I could be wrong).
ReplyDeleteEco-Pads are four separate wells, each with their own file number, sitting on the same pad, offset from each other by about 100 feet, if I remember correctly. Two of the laterals will run in one direction and the other two will run in the opposite direction, so what I see on the map does not appear to fit the definition.
The Ron Viall is a single file number, 17843.
I would assume multiple-well pads, like the Eco-Pads will be placed in known oil-producing fields and would not be wildcats. The Ron Viall was a wildcat.
Unless AEZ was trying or is trying something new, those additional tracks seem to be false boreholes, or whatever they're called. To me it wouldn't make sense to bore another lateral so close to an existing lateral.
Maybe someone else can shed some some light. But, no, this is not an Eco-Pad based on how I understand the concept.
I have an interest in the Ron Viall and the Scout Ticket has coordinates starting 45S 165E ending 392N 59W, 4796N 44W ending 5036N 51W and 1423 N 91E ending 9694N 129W. I dont know they all look like there going somewhere? Sure would like to understand this. When I check other multiple leg wells they really dont include all the coordinates.
ReplyDeleteThe first coordinates I entered in my last note should be 45S 165E ending 5392 59W
ReplyDeleteI honestly don't know. The AEZ press release was a pretty standard report. Time will tell if AEZ tried something new.
ReplyDeleteI guess your right. Maybe a little wishful thinking on my prat. Thanks
ReplyDeleteJust a FYI, 'side tracks' are created to go around debris and other impassable objects. Must have been some junk around the Viall.
