The plug was being installed in preparation for a redrill of the well. The Plug and Abandonment Report is attached. The previous day, cement was circulated to the top of the perforations and squeezed with a coil tubing rig. The perforations were between 9308' - 9326'. The plug was pressure tested to 1500 PSIG for 15 minutes and tagged at 8,717 feet. This provided 591 feet of cement above the perforations. Summary: I witnessed the successful installation of a perforation plug on well PBU DS11-24.

Dear Mr. Oostermeyer: Enclosed is the approved application for permit to drill the above referenced well. The permit to drill does not inde~m~ify you from the probable need to obtain additional permits required by law from other governmental agencies prior to conm~encing operations at the well site. To aid us in scheduling ~leld work, please notify this office 24 hours prior to commencing installation of the blowout prevention equipment so that a representative of the Commission may be present to witness testing of the equipment before the surface casing shoe is drilled, k~ere a diverter system is required, please also notify this office 24 hours prior to commencing equipment installation so that the Commission may witness testing before drilling below the shoe of the conductor pipe. ~~~ tr .., C.
