Siverston Field Update

Updates

IPs and cumulatives are updated periodically. Most recent update, August 6, 2011.

[Note: Denbury Onshore wells below used to be Encore wells. "DNR" is the ticker symbol for Denbury.]

February 4, 2013: in the daily activity report, this date, the 104 wells that were transferred from DNR to XTO in this deal were listed


January 31, 2011: Early in the morning on January 31, 2011, I was updating the Siverston field, see original posting below.  While I was posting, the GIS map server went down. When it came back up, it had been updated and 32 sections had been added to the field:

• 24 sections in T150-97
• 5 sections in T149-97
• 3 sections in T149-98
• The field is now 100 sections, not quite three townships.

These added southern sections are mostly Denbury Onshore/Encore (DNR) wells.

 Original Post

Newfield is reporting some nice wells from the Siverston field. So, with that, it is time to provide a bit of background regarding the Siverston field.

The Siverston field is another typically small field in the Williston Basin. It is just a bit bigger than two townships, totaling 68 sections as of today (January 31, 2011):

• 26 sections in T151-R98
• 36 sections (the entire) T150-98
• 6 sections T150-99

Watford City is in the far west, near the south of the field, in T150-98, sections 17, 18, 19, and 20.

Just north of Watford City -- and when I saw "just north," I mean "just north" -- less than one mile north of the northern edge of Watford City is a string of wells running west to east, two of them complete, or at least having reported IPs:

• 20335, 2,370, Newfield, Holm 150-99-13-24-1H, t8/11; cum 140K 11/12; 5K/month
• 20017, 2,502, Newfield, confidential, Hoffman 150-98-18-19-1H, t8/11; cum 129K 11/12;
• 18641, 1,856, Newfield, Megamouth 1-8H, 2,519, 50K in first 7 months; t8/10; cum 92K 11/12;
• 19112, 2,526, Newfield, Charlotte 150-98-17-20-1H, 3,311, 50K in first 3 months; t11/10; cum 167K 11/12;
• 19594, 1,411, Denbury Onshore/Encore (DNR), Rolfson 21-16SEH, t10/11; cum 135K 11/12;
• 20097, 1,667, Denbury Onshore/Encore (DNR), Lundin 11-15SEH, t7/11; cum 131K 11/12; 

The two Newfield wells, Megamouth and Charlotte, are right across the section line from each other, both long laterals, one running north, one running south.

In all, there are 19 wells on the confidential list in Siverston field. There are three rigs on site in this field (April 16, 2011).
