A hearing covering the matter of the applicant's request was held in conformance with 20 AAC 25.540 at the office of the Commission, 3001 Porcupine Drive, Anchorage, Alaska 99501 at 9:00 a.m. on August 31, 1987. · Members on the staff of the North Slope Borough presented testimony including exhibits. The hearing record was closed at the end of the public hearing. FINDINGS: · Gas accumulations in basal transgressive Jurassic and Cretaceous age sands occur in structural traps peripheral to an apparent diapir-like feature near the village of Barrow, Alaska. · Two gas accumulations near Barrow have been known as the South Barrow Gas Field and the East Barrow Gas Field from which gas is produced for local consumption. ~ From production history the East Barrow Gas reservoir shows an active water-drive, whereas the South Barrow Gas reser- voir has none. The two gas accumulations do not appear to be in communication. Conservation Order No. 233 September 30, 1987 Page 2 · The sands in which the gas accumulations occur in the South and East Barrow Pool are lenticular in nature and irregular in occurrence· · The vertical limits of the gas pool in the South Barrow Gas Pool and the East Barrow Gas Pool may be defined by gas sands penetrated in the North Slope Borough South Barrow No. 13 well which appears to be a typical and representative well. · Well spacing in the South Barrow Gas Pool was regulated by Federal agencies during early development of the pool following its discovery in 1949. · Well spacing in the East Barrow Gas Pool was regulated by Federal agencies during early development of the pool following its discovery in 1974. · Several wells have been drilled, and completed or abandoned under federal jurisdiction prior to this Order and, there- fore, are not in violation of statewide regulations or this Order. ~ The Barrow Gas Field was conveyed to the North Slope Borough from the Federal government in 1984. 10. The gas wells in the South and East Barrow Gas Pools have been on production for many years, and have produced reliably and safely. 11. Barrow is entirely dependent upon the Barrow Gas Field which is the sole supply of heat and fuel for electrical generation; therefore, there are bypasses around the gas production meters which are to remain sealed except in emergencies. 12. Accumulated hydrocarbon liquids and water are purged from wells by two to three minute blowdowns of the tubing at intervals normally between one and four weeks, depending on production rate. 13. Approximate depth of permafrost in the affected area is 550 feet TVD. CONCLUSIONS: 1. It is appropriate to write field rules for the Barrow Gas Field. 2. There are two pools in the Barrow Gas Field. Conservation Order No. 233 September 30, 1987 Page 3 · The Barrow Gas Field has been operated safely and reliably with existing spacing, construction, and operational procedures. NOW, THEREFORE, IT IS ORDERED THAT the rules hereinafter set forth apply to the following described area referred to in this Order as the affected area: UMIAT MERIDIAN T21N RI 6W Sections 4,5,6,7,8,9,16, 17,18,19,20 and 21.

The hydrocarbons contained within the sands in the cretaceous Pebble Shale Unit and Jurassic Kingak formation constitute two reservoirs named the South Barrow Gas Pool and the East Barrow Gas Pool. Rule 2 Pool Definition The South Barrow Gas Pool and the East Barrow Gas Pool are defined as the accumulations of gas which are common to and which correlate with the accumulations found in the North Slope Borough South Barrow No. 13 well between the measured depths of 2210 and 24 72 feet. Conservation Order No. 233 September 30, 1987 Page 4 Rule 3 Well Spacing a) The spacing of all wells drilled and completed within the affected area prior to the date of this Order is approved. b) Nominal 160-acre drilling units are established for the pool within the affected area for all wells to be drilled and com- pleted subsequent to the date of this Order. Each drilling unit shall conform to governmental quarter sections. No more than one well may be drilled into and produced from each drilling unit. A pool may not be opened in a well closer than 1000 feet to any other well opened in the pool. A pool shall not be opened in any well closer than 1500 feet to the exterior boundary of the affected area or closer than 1500 feet from the boundary where ownership changes. c) Upon application by the operator accompanied by sub- stantiating data based on engineering and geological principles, the Commission may administratively approve modifications to well spacing. Rule 4 Casing and Cementing Requirements a) Surface casing to provide for proper anchorage to the surrounding formation, to prevent uncontrolled fluid flow, and to protect the well from the effects of permafrost thaw-subsidence or freeze-back loadings, shall be set at least 500 measured feet below the base of the permafrost. Sufficient c. ement shall be used to fill the annulus behind the casing to the surface. 'b) Alternate means for maintaining the integrity of the well from the effects of permafrost thaw-subsidence and freeze- back may be administratively approved by the Commission upon application and presentation of data which show the alternatives are appropriate, based upon accepted engineering principles. Rule 5 Completion Practice Wells completed for production from the Barrow Gas Pools are to utilize casing strings or liners cemented through the production intervals. The Commission may administratively approve alternate completion methods where appropriate. Rule 6 Gas Venting or Flaring a) The venting or flaring of gas is prohibited except as may be authorized by the Commission for facility safety, opera- tional necessity, and in cases of emergency. Conservation Order No. 233 September 30, 1987 Page 5 b) Bottom-hole accumulated hydrocarbon liquids and water may be purged from wells by periodic tubing blowdowns of brief duration.

Box 3507 Barrow, AK 99723 RE: Conservation Order No. 233 Request for Administrative Approval Rule 3: Well Spacing Rule 5: Completion Practice Barrow Field South Barrow Gas Pool East Barrow Gas Pool Dear Mr. Dunn: In accordance with Rules 3 and 5 of Conservation Order No. 233.000 (CO 233), the Alaska Oil and Gas Conservation Commission (Commission) hereby GRANTS the North Slope Borough (NSB)'s request for administrative approval revising well spacing and completion practice requirements for the South Barrow Gas Pool and the East Barrow Gas Pool of the Barrow Field. Rule 3 of CO 233 establishes nominal 160 -acre drilling units for the South Barrow and East Barrow Gas Pools, and it requires that each drilling unit conform to a governmental quarter section. In addition, Rule 3 specifies: (1) no more than one well per drilling unit, (2) a distance of at least 1000 feet between wells open to the pool, and (3) a 1500 -foot setback from the external boundary of the Affected Area. Rule 5 of CO 233 requires every production well in these pools utilize casings strings or liners cemented through the production intervals. Rules 3(c) and 5 of CO 233 allow administrative approval for modifications to well spacing and alternate completion methods, respectively. CO 233 was issued by the Commission September 30, 1987. At that time, nearly all production wells were vertical or moderately inclined, and well casings and liners were typically cemented in place. Improvements in drilling and completion technology have since made horizontal, extended -reach production wells commonplace. A single, long horizontal well is now drilled in lieu of several older - style, vertical or inclined production wells. These horizontal wells are placed and oriented in accordance with reservoir and fault trends, rather than governmental CO 233.001 • • November 19, 2010 Page 2 of 2 section lines, rendering older spacing rules, such as Rule 3, obsolete. Packerless completions and uncemented, slotted liners are now common practices for wells in Alaska. NOW, THEREFORE, IT IS ORDERED THAT the rules governing production operations in the Barrow Field as described in Rules 3 and 5 of CO 233 are revised as follows: Rule 3 Well Spacing Within the Affected Area established by CO 233, there shall be no restrictions as to well spacing except that no pay shall be opened in a well within 1500 feet of an external property line where the owners and landowners are not the same on both sides of the line. The Commission may administratively approve modifications to well spacing as long as the change does not promote waste or jeopardize correlative rights, is based on sound engineering and geoscience principles, and will not result in an increased risk of fluid movement into freshwater. Rule 5 Completion Practice Wells may be completed without a packer. Uncemented, slotted liners are acceptable as completions. The Commission may administratively approve alternative completion practices as long as the change does not promote waste or jeopardize correlative rights, is based on sound engineering and geoscience principles, and will not result in an increased risk of fluid movement into freshwater.

CO 233 Rule 4a states that surface casing shall be set 500' measured below base of permafrost. The NSB requests that the surface casing setting depth be changed to 200' TVD below base of permafrost (1150' TVD /SS) in order to facilitate drilling of these two new extended reach wells in the field. Placement of the surface casing at 1150' TVD /SS will allow the planned wellbores to become horizontal at the pay zone without excessive dogleg severity. The Commission finds that this change is reasonable and is based on sound engineering principles. Surface shoe placement under this changed rule will provide the required anchorage to the surrounding formation, prevent uncontrolled flow, and protect the well from permafrost thaw - subsidence loading conditions.

The administrative approval request specifically pertains to the placement of the well surface casing, 9 -5/8 ", 40 #, L80 BTC -M, shoe placement depth equivalent to 200 vertical feet below the base of permafrost in the East Barrow Gas Pool — identified at 950 ft. tvd /ss. Design Methodology The average base permafrost depth over the entire East Barrow Field is found around 1000 feet subsea. Locally, in the area where the Savik #1 and #2 wellbores are planned, the base permafrost is expected to be found between 925 -950 feet tvd /ss. This shallower depth is based on static temperature surveys from two nearby wells, S. Barrow #19 and E. Barrow #21 (Fig. 1). These are the most current static surveys acquired in this area. Savik #1 is planned to be 600 ft from S.B. #19 and 1850 ft from E.B. #21, and Savik #2 is planned to be 450 ft from S.B. #19 and 1850 ft from E.B. #21. The surface shoe placement at 1150 ft. tvd /ss will provide the required anchorage to the surrounding formation, prevent uncontrolled fluid flow, as well as protect the well from permafrost thaw - subsidence and freeze back loading conditions. Formation integrity tests (FIT), performed on previously drilled wells in the East Barrow Gas pool where surface casing was positioned at or near 1150 ft tvd /ss (Fig.2) suggest adequate shoe strength to drill to the proposed intermediate 7" 26# L80 BTC -M casing point — at top of the Upper Barrow Sandstone (1947 tvd /ss) . Additionally, Fig.(3) provides illustration of 7 South Barrow Gas Field wells • • April 18, 2011 where surface casing was ran and cemented at depths approximately equal to or less than 1150 ft. tvd. Fig (4), provides a table reference for South Barrow wells ( SB: 5 thru 20) , documenting surface casing setting depths as well as noted FIT information. Summary Review of wellbore temperature profiles in wells South Barrow #19 and East Barrow #21 suggest that the base of permafrost is located between 925 -950 tvd /ss. Sonic log readings in the South Barrow #19 well indicate that the base of the ice - bearing permafrost is at 790 feet tvd /ss. PRA, providing the well construction design engineering function on behalf of the North Slope Borough, proposes that the surface casing for wells to be drilled in the East Pool of the Barrow Gas Field (Savik #l, Savik #2) be positioned at 200 vertical feet below the base of permafrost (32 degree isotherm) in the South Barrow #19 well, or 1150 ft tvd /ss.

The NSB is the operator of the Barrow and Walakpa Gas Fields and owns 100% of the rights to the gas in both fields. The NSB is requesting modifications to the existing Pool Rules to allow for unlimited well spacing in both gas fields and to allow for packerless completions and use of uncemented slotted liners in the Barrow Gas Field. The pool rules for the Walakpa Gas Field already allow for packerless completions and use of uncemented slotted liners in that field. Both Conservation Orders provide that the Commission may administratively approve modifications to well spacing. Rule 5 of Conservation Order 233 provides that the Commission may also administratively approve modifications to completion practices. The NSB requests that the Commission administratively approve the modifications to the Pool Rules outlined in the enclosures to this letter. Supporting engineering and geologic information is also enclosed to support these requests. The NSB is planning to drill two new horizontal gas wells in the East Barrow gas field and four new horizontal wells in the Walakpa gas field. These new horizontal wells will require individual well spacing exceptions if unrestricted well spacing is not approved in both fields. Likewise, the completion design for these new wells includes a liner top packer with an uncemented slotted liner across the gas sands in each well and that no packer is run on the tubing string in each well. This 1 I • I I completion design requires an exception to the Barrow gas field pool rules or a modification of the pool rules. i The NSB believes that amendments to the existing Pool Rules are the most expeditious way to proceed in this situation. Petrotechnical Resources Alaska (PRA) has been retained by the NSB to provide technical and management the ement services for this project and is authorized to represent the NSB before g p J p Commission. If you have any questions concerning this application please contact me immediately. We are making plans to barge the rig and heavy equipment to Barrow this coming summer and spud our first new gas development well as early as September 2011. I Sinc e y, Matt Dunn, Director CIPM Enclosures CC: Tom Walsh, PRA William Van Dyke, PRA 2 ENCLOSURE #1 Barrow Gas Field Request to Amend Rule 3 and Rule 5 of Conservation Order 233 The North Slope Borough (NSB) requests that Rule 3 of Conservation Order 233 be amended to read as follows: RULE 3 WELL SPACING. a) The spacing of all wells drilled and completed within the affected area prior to the date of this Order is approved. b) Unrestricted well spacing is established for the pool within the affected area for all wells to be drilled and completed subsequent to the date of this order. There shall be no restrictions as to well spacing except that no pay shall be opened in a well within 1500 feet of an external property line where the owners and landowners are not the same on both sides of the line. c) Upon application by the operator accomplished by substantiating data based on engineering and geological principles, the Commission may administratively approve modifications to well spacing. The NSB requests that Rule 5 of Conservation Order 233 be amended to read as follows: RULE 5 COMPLETION PRACTICE. Wells may be completed without a packer. The Commission may administratively approve alternative completion methods where appropriate. Justification for the Requests The amendments proposed above will allow the operator greater flexibility in placing new wells as the pool is developed and will help to maximize ultimate recovery from the pool. The rules will not (1) diminish ultimate recovery from the pools, (2) promote waste, (3) jeopardize correlative rights, or (4) increase the risk of movement of fluids into fresh water. Correlative rights will be protected by requiring a 1500 foot set back from the external property lines where the owners and landowners are not the same on both sides of the line. Well spacing is governed by 20 AAC 25.055 unless specific pool rules are adopted under 20 AAC 25.520. Well spacing requirements were incorporated into the pool rules that were appropriate when vertical wellbores were used to develop the pool. The proposed use of long horizontal wellbores requires an amendment to the current rule. The NSB believes that horizontal wells completed with liner top packers and uncemented slotted liners across the face of the pay sand are the best way to complete the new wells. This will add significant productivity to the fields and continue development of the pools in a cost effective manner. In addition, the use of packerless completions is the current production practice in both fields and from an operational practice is the best way and a proven way to produce the pools given 3 the potential for gas hydrates to form in the tubing sting or even at the bottom of the wellbore. With no packer in place methanol can be circulated down the tubing and down the tubing by inner casing string annulus to remove hydrate plugs. This production practice has worked successfully for decades in the field. Commission staff has ready access to the well logs, well files and the production/pressure history of the wells in the Barrow and Walakpa fields. Geologic information on the pools was provided when the Barrow Gas Field pool rules were adopted in 1987 and the Walakpa Gas Field pool rules were adopted in 1991. None of those data and materials is enclosed again with this application. The Barrow and Walakpa gas sands are relatively thin and relatively tight. Horizontal wells completed with uncemented slotted liners in the pay zone should provide for much higher well flow rates at much lower pressure drawdowns across the sand face relative to vertical wellbores completed with cemented /perforated liners across the producing sand face. Fewer horizontal wells are needed to provide the same gas deliverability relative to vertical wellbores. However, horizontal wellbores require an amendment to the well spacing requirements in both the Walakpa and Barrow gas fields. The use of uncemented slotted liners requires an amendment to the Barrow gas field pool rules since that rule was written with conventional well completion technology in mind. The use of uncemented slotted liners in horizontal wells along with a liner top packer has proven to be a successful completion technology for these types of wells. Both the Walakpa and Barrow gas sands are competent sands. Little sand production has been experienced to date from the producing wells and little to no sand production s expected from the proposed wells. The new horizontal wells in the East Field will replace several of the existing damaged and/or mostly depleted gas wells in that field. In the future, new wells may be drilled in the South Field as well. Studies have indicated that the East Field is being re- charged with natural gas at least in part by dissolution of natural gas hydrates that overlie parts of the field. The new wells are designed to take advantage of this phenomenon. END 4 ENCLOSURE #2 Walakpa Gas Field Request to Amend Rule 3 of Conservation Order 274 The North Slope Borough (NSB) requests that Rule 3 of Conservation Order 274 be amended to read as follows: RULE 3 WELL SPACING. a) The spacing of all wells drilled and completed within the affected area prior to the date of this Order is approved. b) Unrestricted well spacing is established for the pool within the affected area for all wells to be drilled and completed subsequent to the date of this order. There shall be no restrictions as to well spacing except that no pay shall be opened in a well within 1500 feet of an external property line where the owners and landowners are not the same on both sides of the line. c) Upon application by the operator accomplished by substantiating data based on engineering and geological principles, the Commission may administratively approve modifications to well spacing. Justification for the Requests The amendments and additions proposed above will allow the operator greater flexibility in placing new wells as the pool is developed and will help to maximize ultimate recovery from the pool.

Little sand production has been experienced to date from the producing wells and little to no sand production is expected from the proposed wells. The new horizontal wells in the Walakpa Field will add to the existing well set. They will provide significant new deliverability to the field.

As you can see on the map, spacing 19 within the fields was controlled by decisions made by the Federal 20 Government over the long development time within the fields.

SMITH: Well, as a matter -- for the record, 3 I would like to point out that these fields for some time in 4 literature, both from the federal standpoint and even our oil 5 and Gas Conservation Commission's statistical report, have been 6 known as two separate fields. And -- and as I understand it, the 7 two -- the -- the reservoirs themselves, the two -- if there g are two pools, separate and distinct pools, one -- the one to 9 the east, the East Barrow Field, the most recent development, 10 is a water -drive reservoir, clearly, distinctly different from 11 the South Barrow Field. So generally speaking we would think 12 of this in terms of I think one field and two different pools, 13 but of the same field, but it's rather unique even in that respect 14 in that we're designating an outline -- or one area that covers 15 two pools if you think of it that way, so I don't know exactly 16 how it will come down when we write it yet completely as -- as 17 to how we'll thrash it out,.it -- because there's some 18 inconsistencies here with what we've done previously, and -- and 19 to handle this. 20 MR. CHATTERTON: I'd like to follow up on what 21 Commissioner Smith has said. What seems logical to every -- to 22 most people I think would be that you have a Barrow Gas Field 23 and you have a few pools there, and -- and it's nothing 24 inconsistent with our -- we -- we have established a precedent 25 before of writing the same rules for multiple pools, most recently i R & R COURT REPORTERS 810N STREET.

CHAPMAN: The well was shut in as subeconomic 2 in -- somewhere around 1980. The reason it was shut in is that 3 it produced for a significantly long amount of time of relatively 4 dry gas. In the last two years of its life it had suffered 5 some incursion of water into the well bore, and they were having 6 to blow the well to -- to clear the well bore very, very 7 frequently. And due to that, they -- it seems that in some 8 areas of the -- the south field, although they're -- it's a 9 very straight forward depletion mechanism, low rate wells tend to 10 pick up a little water for some reason, and it was shut in as 11 subeconomic due to water production and low productivity. 12 MR.

They are contained in lands whose surface owner- ship is held by the Ukpeagvik Inupiat Corporation and whose subsurface estate is owned by and operated by the North Slope Borough. The fields were originally developed by the Federal Government from the early 1950's through their conveyance to the North Slope Borough in October, 1984. The Borough has operated the Fields since. Recognizing depletion and diminishing production capacity, the Borough instituted a drilling and workover program in the first half of 1987 in order to ensure adequate energy supplies to Barrow. Barrow is entirely dependent on the fields for their sole supply of heat and fuel for electrical power generation. As seen on the log of South Barrow #13, (See Tab No. 13 the Barrow Sands are composed of numerous seperate stringers, some of which pervade the field, others of which do not. This lenticular and spotty sand deposition is characteristic of the Barrow Sands wherever drilled to date. Production and reservoir engineering analysis Draft Testimony Page _ of the South and East areas indicate dis/tincdriv decline e mechanisms. I In the South, the wells continue to follow he long term depletion stable e ec 1 ine para- volumetric drive mechanism that has show stable meters since the 1950's. Conversely, in the East, after initial semi-steady state stablization, a water drive is apparant. Decline curves from No. 6 in the South and No. 14 in the East areas (See Tabs No. 2 & 3) are shown as examples. Additionally, structure maps on the Lower Barrow Sand, (See Tabs 4 & 52 are presented. We propose that all activity within the bordered area shown on the attached map (See Tab No. 6) be subject to the Proposed Pool Rules. The darkened area is Borough owned estate. We further propose that the Barrow gas sands be defined as those stratigraphically equivalent sands in any well, which are correlative to those sands in the South Barrow Well No. 13 from 2 feet to 2420 feet. As you can see on the map, spacing within the fields was controlled by decisions made by the Federal Government over the long development time within the Fields. The South Field, originally discovered in 1949, has the wells spaced as shown. The East Field, developed in the late 1970's and early 1980's, is more widely spaced as shown. The Barrow Gas Fields have been on production for many years and have produced reliably and safely. It is our intent to ask for the Commission to make those Pool Rules specific to the Barrow Gas Fields that will encompass the existing facilities and will address practices proven by historic operation to be of a safe and conservative nature. Draft Testimony Page 3 We request that rules include marking all wells clearly with a sign identifying the well as to its number. We also request that all existing wells be recognized as legal spacing. For future wells, we request to have a well to well distance no less than 1,320 feet and that they be drilled at least 1,500 feet from a line at which ownership changes from the owners (lessors) of the subsurface estate. Wells are requested to be spaced on 160 acres. Wells South Barrow 2, 3, 4 & 16 were abandoned by the Federal Government. Their abandonment is requested to be approved by the Commission. Before you is a typical well schematic of South Barrow #18, (See Tab No. 7) a well in the East Barrow Gas Field. Production is taken up the tubing by production casing annulus, which is used as a vertical separator, and cooling tower, so that gas arriving at the surface is at a depressed dew-point. Accumulated hydrocarbon liquids and water build up at the bottom of the hole are conveyed by blowdown up the tubing at intervals normally between one week and one month depending on production rate. During this process, normally lasting two to three minutes, a minor amount of gas is vented. Approval of the continuation of this practice is recommended. Additionally, approval of the packer- less completion is recommended. Due to the life support nature of this direct production to living facilities, bypasses around meters are necessary. It is recommended that the Commission approve these bypasses, that will be lead sealed, and will not be opened except in the case of an emergency due to a meter blockage or for meter servicing. F • • Draft Testimony Page 4 Additionally, we have requested Commission approval of South Barrow #5 as a disposal well. This well will be utilized for disposal of liquid drilling wastes and completion fluids as well as incidental salt water produced from the formation. A schematic of Well #5,(See Tab No. 8) as well as the information normally required by the Commission for approval of a disposal well is herein presented.(See Tab No. 9) Gentlemen, the Barrow Gas Fields have proven to be an effective system in terms of production practices, which are able to safely meet the life support requirements of the northernmost population center in Alaska. While the North Slope Borough intends to continue to comply with Oil and Gas Conservation Commission Regulations, these Pool Rules are required for continued, effective production practices. It is our opinion that these requested Pool Rules will comply with the Commission's responsibility of resource conservation and waste prevention. We thank you very much for your time and effort in working with us, and look forward to a continued good relationship between the State and the Borough. McEvoy 3000 .
