VanDusen Prudhoe Bay Unit DS 12-4 -2- July 25, 1979 Pursuant to AS 38.40, Local Hire Under State Leases, the Alaska Department of Labor is being notified of the issuance of this permit to drill. To aid us in scheduling field work, we would appreciate your notifying this office within 48 hours after the well is spudded. We would also like to be notified so that a repre- sentative of the commission may be present to witness testing of blowout preventer equi~ent before surface casing shoe is drilled.

Logs will be run across selected intervals. A 13-5/8" 5000 psi RSRRA BOP stack will be used. The BOP equipment' will be pressure tested each week and operationally tested each trip. A string of 5½" 17# L-80 tubing, packer & necessary provisions for subsurface safety equipment will be run. A non-freezing fluid will be left in all un- cemented annuli within the permafrost interval. Selected intervals within the Sadlerochit will be perforated and reported on a subsequent report. A 5000 psi WP wireline lubricator, tested to working pressure, will be used on all wireline work. Well will be flowed to production facilities during perforating & testing. The downhole safety valve will be installed and tested upon conclusion of the job. IN ABOVE SPACE DESCRIBE PROPOSED PROGRANI: If proposal is to deepen give data on present productive zone and proposed new productive zone. If proposal is to drill or deepen clirectionally, give pertinent data on subiutface locations and measured and true vertical depths. Give blowout preventer program.
