Only 20' of perforations were shot in 4-25. All of the perforations were shot in Zone la thereby negating the need for a spinner survey. Additional perforations in Zone I are planned. The timing of the perforations, however, is after the initial six month time period has passed. A production profile will be run subsequent to the additional Zone 1 perforations.

Dear Mr. Oostermeyer: Enclosed is the approved application for permit to drill the above referenced well. The permit to drill does not indemnify you from the probable need to obtain additional permits required by law from other governmental agencies prior to commencing operations at the well site. To aid us in scheduling field 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. %~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.

A 20", 2000 psi annular diverter may be installed and operationally tested prior to spud. The 13-5/8", 5000 psi, RSRRA BOPE stack will be installed and tested (rams 5000 psi, annular 3000 psi) weekly upon installation and operationally tested each trip. After reaching TD, logs will be run across selected intervals. The well will be completed as an injector using a workover rig at a later date. A 4-1/2" tubing string and packer will be run and set above the Sadlerochit. A downhole safety valve will be installed and tested upon completion of the job. Selected intervals will be perforated in the Sadlerochit formation and reported on subsequent reports. Reserve pit fluids will be disposed of down the 7-5/8" x 13-3/8" annulus of this well. The 7-5/8" x 13-3/8" annulus will be left with a non-freezing fluid during any interruption in the disposal process. Upon completion of the disposal process, the annulus will be sealed with 300 sx of cement followed by Arctic Pack. Wells within 200' of the proposed well are: 4-11 47' ~ 2450'; 4-12 57' ~ 1850'; 4-13 180' ~ surface; 4-26 118' ~ surface. 23.
