Spearfish Formation Activity -- Madison Formation Activity -- Petro Harvester Acquires Sagebrush Madison Wells in Bottineau -- North Dakota, USA

This was part of the Daily Activity Report, April 7, 2011, earlier but deserves its own stand-alone post.

Ward-Williston had a full page of well name changes on today's daily activity report (April 7, 2011). The previous names were all surface-owner specific, and similar, but now they have all been changed to "MRPSU XX-XX." The first two digits refer to the section and the second is specific for the well. I assume "MRPSU" stands for Mouse River Park Spearfish Unit.

In addition, there was a change in operator from Sagebrush Resources to Petro Harvester Operating Company, LLC, affecting about four pages of wells. I didn't count them, but estimating about 40/page, it appears there was about 140 wells that changed hands. Many of these new Petro Harvester wells were up in Bottineau County. Most of the well names did not have an H-designation, suggesting they are vertical wells. A few did have the H-designation. It appears all the wells target the Madison formation.
