Smith Commissioner State of Alaska Alaska Oil & Gas Conservation Commission 3001 Porcupine Drive Anchorage, Alaska 99501 Subject: 1 R- 19 (Permit No. 91-81) Revised Well Completion Report Dear Mr. Smith: Enclosed is the requested revised well completion report which will close out 1 R- 19 (Permit No. 91-81). 1R-19 was originally permitted as a disposal well. The well was drilled to 4077' TVD, logged and 9-5/8" casing was run and cemented. The 9-5/8" cement job was not adequate to use the well for disposal. On 6/19/91 1R-19 was permitted to redrill as a producer with a proposed depth of 6906' TVD (Permit No. 91-85). No P & A operations were done. This form is intended to close out: Permit to Drill #91-81. Sincerely, A.W, Area Drilling Engineer RECEIVED APR Alaska Oil & Gas Cons. Anchorage /",RCO Alaska.
