A workover in 1992 added additional perforations in the producing Tyonek sand and ran a gravel pack completion.The well is currently on production making around 200 MCF/D with no water.The gravel pack was perforated with thru-tubing guns in March 2014. Notes Regarding Wellbore Condition • Well is currently flowing at 170 MCF/D with a 60 psi flowing tubing pressure. • Wellbore is vertical. OBJECTIVE OF WORKOVER Re-perforate the lower portion of the gravel-packed Tyonek interval. E-line Procedure: 1. MIRU E-line, PT lubricator to 1,500 psi Hi 250 Low. 2. RU 1-11/16" 6 spf HC wireline guns(will use 1 each 30'gun). 3. RIH and perforate Tyonek interval from 7,924'-7,954' (1 run,total of 6 spf). a. Proposed perfs shown on the proposed schematic in red font. b. Final Perfs tie-in sheet will be provided in the field for exact perf intervals. c. Correlate using SLB DIL Log dated 7/01/66 (Tie-in log depth is 7,924'-7,954'). d. Correlate w/GR/CCL. *No Gamma/Pressure/Temperature tool*. e. Record tubing pressures before and after each perforating run. 4. RD E-line. 5. Turn well over to production. Attachments: 1. As-built Schematic 2.

A workover in 1992 added additional perforations in the producing Tyonek sand and ran a gravel pack completion.The well is currently on production making around 200 MCF/D with no water. Notes Regarding Wellbore Condition • Well is currently flowing at 200 MCF/D with a 70 psi flowing tubing pressure. • Wellbore is vertical. OBJECTIVE OF WORKOVER Re-perforate the gravel-packed Tyonek interval. E-line Procedure: 1. MIRU E-line, PT lubricator to 1,500 psi Hi 250 Low. 2. RU 2.0" 6 spf Connex XLS HC wireline guns(will use 1 each 20'gun). 3. RIH and perforate Tyonek interval from 7,904'-7,924' (1 run,total of 6 spf). a. Proposed perfs shown on the proposed schematic in red font. b. Final Perfs tie-in sheet will be provided in the field for exact perf intervals. c. Correlate using SLB DIL Log dated 7/01/66(Tie-in log depth is 7,904'-7,924'). d. Correlate w/GR/CCL. *No Gamma/Pressure/Temperature tool*. e. Record tubing pressures before and after each perforating run. 4. RD E.-line. 5. Turn well over to production. Attachments: 1. As-built Schematic 2.

You requested that I provide you with written procedures of the exact changes we intend to make before you can advise us on which State regulations we must comply with. Here are two examples of the changes we want to make to the wells. , .~-- ~6oz~ Ivan River Well IRU 4i-i production rate is limited by line pressure and friction pressure drop. We intend to prevent the limitation by punching holes in the casing and tubing and flowing gas to the surface through the tubing and casing annulus. ~-~ "7~) -OO0 Pretty Creek Well PCU-2L has been loading up with water, which hampers free flow of reservoir gas into the well. Even though our field personnel have been blowing the well down periodically to get rid of the water, we have concerns that continuous blowing down of the well might cause the well to sand which may lead to loss of reserves. To solve this problem, we would like to perforate the tubing above the packer and use a timer or tubing-casing pressure difference actuator to automatically unload water. The device will shutin the well periodically then open it to flow. The gas in the annulus would help lift the water. I would like to know the relevant or applicable State regulations that govern the reconfigurations we intend to make. Please direct questions about this subject to Sam Darkwah at 263-78-64.

NOTICE OF POSSIBLE ABNOPu~L~LLY NIGH PRESSURED SANDS IVAN RIVER AREA During the drilling of Ivan River Well #44-1, super normal pressures were encountered in salt water bearing sands below 12,000'. After a total depth of 15,269' had been reached, the lower portion of the hole was abandoned due to a drill collar fish from 9,986'-10,535'. The fish was squeezed with 300 sacks of cement and the hole above the fish plugged with 250 sacks of cement. While attempting to sidetrack the original hole at 9,111', high pressure water broke into the well bore requiring dril~ling fluid of 131 pcf weight for control. The hole was then squeezed and abandoned below the 9 5/8" casing shoe at 8,9~8' with 800 sacks of cement..

"'.~ Alaska Oil and Gas Conservation Commission Gas Well Open Flow Potential Test Report (4-Point Test) Form No, G-1 Authorized by Order No. 1 Effective October I, 1958 IVAN RIVER UNIT #44-1 OPEN FLOW POTENTIAL TEST I NTRODUCT I ON This Memorandum presents the results of a foUr point open flow potential test obtained on October 7 and 8, 1966 from well Ivan River #44-1. The test was witnessed by Messrs' Wunnicke, United States Geological Surge¥, Kugler, Alaska's State Oil ~ Gas Section of the Division of Mines and Minerals, Waite and Tinker, Standard Oil Company of California, Western Operations, Inc~ RESULTS 1. The Open Flow Potential for Ivan River Unit #44-1 is 25,000 MCF/D as shown on attachment 1. 2. Attachment 2, presents the basic data obtained from the subject test. 5. Attachment 5, represents the mechanical condition of the well during this test. 4. When the subject interval was originally tested there was evidence of sand being produced with the gas. For this reason no attempt was made to record the flowing bottom hole pressure with an Amerada depth pressure bomb. 5. A static midpoint pressure was obtained prior to the test. Flowing bottom hole pressures were calculated by the Poettmann Method from the observed surface tubing pressure.. 6. Alcohol was injected in the flow line ahead of the bean during the test, in an attempt to prevent hydrate formation. 7. At each producing rate for the test, surface freezing was noted. This freezing necessitated thawing the line prior to initiating another test. 8. The gradual freezing noted in the surface lines reduced the production rates near the end of each test. Stabalized rates were obtained only at the beginning of the test. 9. With the severe surface freezing problems on each bean and evidence of downhole freezing on a 16/64" bean, it was decided not to attempt to produce the subject well at a bean size over 16/64".

The purpose of the tests were to establish points to determine the open flow potential. The maximum rate observed during the test was approximately 5,700,000 CFGPD, 16/64" choke, and a flowing tubing pressure of 2985~psig. Production is from perfo~ations from 7935' to 7955'. Troubled by freezing flow lines with temperatures at -100"F,. the company representatives obtained all the data that was possible under the conditions. H~/cJh Eno. cc: J. A.

Pressure bombs had been run in hole to record formation pressures during test but evidence of mud and sand either entering perforations or being sucked up from sump indicated it would be safest to keep bomb out of hole during test. As a result, no pressures were recorded in well. An initial shut-in pressure of 4130# had been reported from a previous formation test.
