Update on eight Skarston wells on an 8-well pad.

According to the NDIC May, 2016, production data, the following Skarston wells were "SI": 21664, 25859, and 25856. The well drilled in 2012 (#21664) is now classified as "AB" according to the file report. "Batch-drilled,"  spud date, TD date; test date:.

According to a sundry form dated February 16, 2016: Statoil reqeusted a waiver to NDAC Sec 43-02-03-55 and seeks time to meet compliance. The wells listed below (the same wells above) were batch drilled on a multi-well pad. Statoil requests an extension to be granted for all wells on the pad based on the last day total depth was reached for the last well on the pad [4/14/15, TD date for #29564]. The Skarston 1-12XE #1H was the last well batch drilled on the multi-well pad for the previously listed 8 wells. In addition, production from the existing Skarson 1-12 1H (#21664) ceased to accommodate drilling operations. A letter dated 1/25/2016 from Rick Dunn (NDIC) requires production be restored or the well be plugged and abandoned. Statoil requests that the extention be granted for all nine wells until 4/14/2016 to be bring the wells into production.

*********************************

This has to do with the Skarston well that was reported yesterday, a DUC:

• 25858, 5,010, Statoil, Skarston 1-12 5H, Banks, a middle Bakken well, t3/16; cum see above.

With another Skarston well on this pad, there was evidence of communication with another well from a pad in a neighboring section. Link here: http://themilliondollarway.blogspot.com/2015/11/evidence-of-communication-between-wells.html.

Other pertinent links:

• communication between formations? February 7, 2010 
• possible halo effect between formations in Truax oil field, February 21, 2016

I used to track the Skarston wells elsewhere, but will move the tracking to this post.

Eight wells on an 8-well pad, "batch-drilled," spud date, TD date; test date:

• 25854, 3,098, Skarston 1-12 2TFH: 9/21/14; 11/12/14; t4/16; cum 8K over first 12 days;

• 29564, 3,583, Skarston XE 1H: 11/11/14; 4/14/15; t3/16; cum --

So, between 11/12/14 and 4/14/15: 8 wells on an 8-well pad drilled to depth. I assume they can be fracked within a couple of weeks, and oil in the national pipeline system within 30 days.

As of April, 2016: all on SI/NC status.
