I 0/2 I/9 6: A Fullbore Acid Stimulation Treatment was pumped to enable improved MI Injection as follows: MIRU & PT equipment. Pumped acid treatment fluids through the perforation intervals (above). Pumped: a) 100 bbls 2% NH4CI Water to load well, followed by b) Shutdown for 10 minutes. Resumed pumping: c) 40 bbls 2% NH4CI Water @ 2/4/6/8 bpm rates for step rate test, followed by d) 50 bbls 12% HCI w/10% Xylene, followed by e) 25 bbls 9% HCI - 1% HF, followed by f) 25 bbls 12% HCI w/10% Xylene, followed by g) 100 bbls 2% NH4CI Water Flush @ 4 - 6 bpm, followed by h) 20 bbls Benzoic Acid Flake Diverter in 24% NH4CI solution @ 4 bpm, followed by i) 50 bbls 12% HCI w/10% Xylene, followed by j) 25 bbls 9% HCI- 1% HF, followed by k) 25 bbls 12% HCI w/10% Xylene, followed by I) 100 bbls 2% NH4CI Water Flush @ 4 - 6 bpm, followed by m) 32 bbls Benzoic Acid Flake Diverter in 24% NH4CI solution @ 4 bpm, followed by n) 50 bbls 12% HCI w/10% Xylene, followed by o) 23 bbls 9% HCI - 1% HF, followed by p) 17 bbls 12% HCI w/10% Xylene, followed by q) Shutdown. Well locked up w/BAF stage on formation. PU to 4500 psi on well & rocked well between 4500 - 100 psi. Well locked up; could not flow well back to tank. Rigged down & MOL. MIRU CTU & PT equipment. RIH w/nozzle & jetted: r) 80 bbls Meth Water to circulate stimulation fluids from wellbore, followed by s) 200 bbls 2% NH4CI Water, followed by t) 10 bbls Meth Water, followed by u) 16 bbls 100% Methanol to jet perfs & jet past obstructions at 11747' MD, followed by v) 220 bbls 2% NH4CI Water to jet to 11850' MD & jet ©OH w/CT. Performed injectivity test w/injection @ 1.4 bpm/1300 psi. RDMO CTU. Returned the well to MI & attempted to obtain a valid MI injection rate. The well took MI at below meterable rates. The cumulative MI injection volume placed through 10/31/96 is estimated to be less than 45 MMscf. MI had been < 1 MMscf/day @ 3300 whp. I 1/20/96: Completed MI injection project. Disassembled MI Huff n' Puff project injection line to well. Placed well on production. Well would not flow. SI well. Evaluating future work options.

As the attached AOGCC BOPE Test Report shows there was one failure. A flange leaked on the stack. This was tightened and retested. The tubing hanger packing leaked during the entire test, so all flanges and valves were visually checked for leaks and none were found. Everett Potter, ARCO rep., told me that when the tubing was out of the hole and a test plug could be run, a complete test would be performed. The lower pipe rams and the 3.5" kelly would be picked up and also tested. The rig was clean and all equipment seemed to be in good working order. The location was clean and good access to the rig was OK. Summary: I witnessed the BOPE test on Doyon rig 16 - test time 3 hours - 1 failure.

This material will consist primarily of drilling fluids, rig wash water and snow melt. Wells will be drilled, completed, and fluids pumped as outlined in the January 25, 1990 report. Approval is sought for the following well: DS 16-23 Attached is a well-specific summary sheet which indicates the surface hole location, anticipated pumping depths, and the requested start and stop dates for the well. Please note that this approval request is an extention of a well that was previously authorized for annular pumping but for which no fluids have been pumped.
