Mark Schlagenhauf P.E. P.S. Please file a form 6 (s) for each API number (original wellbore and intercept wellbore). I expect the reports will be similar.

WHSS 1 API – 05-123-41104 Ernie Adamson GU #1 API – 05-123-08288 We successfully intercepted below the fish into the Ernie Adamson wellbore at 595’ and have worked our way downhole to a depth of 4660’. We have been continually circulating out gas for the past 3 days as we have slowly made our way down the hole. We would like to call the well early and begin plugging our way out of the hole as detailed below. The only deviation to the original plan is to skip the Niobrara coverage cement plug. We will not set our Niobrara plug as planned from the TD of 7057’ to 6540’. We will pump a plug from approximately 4550’ to 3950’. This plug will be pumped in 2 stages to minimize chance of gas working its way through the cement. We will wait on the cement to build compressive strength and tag the TOC in the openhole. We will then come up hole and pump a freshwater isolation cement plug also in 2 stages from approximately 1500’ to 250’. This plug will also be tagged for confirmation. Please let me and/or Joshua Mallery know if you see any issues with this change in plans.
