Id Dear Mr. Dygas: Attached is a Sundry Notice, requesting approval to temporarily abandon (TA) 30 wells in the Swanson River Field for a period of 12 months. This Sundry Notice is being submitted to comply with 43 CFR 3162.3-4, paragraph (c) of the Bureau of Land Management Regulations. As shown on the Sundry Notice, we are requesting that the 12 month approval period for the proposed TA wells coincide with the Plan Period of the Thirtieth Plan of Development and Operations for the Swanson River Field; i.e. April 1, 1994 to March 31, 1995, Two information sheets are attached with this Sundry Notice 'request. Attachment I lists the proposed TA wells using the same-format as submitted last year. The two general categories are shut-in wells being held for evaluation for current uses or disposition and wells being held for future uses during field blowdown. Attachment 2 gives a brief explanation for each well that has been added or removed from the proposed Temporarily Abandoned List. Three wells SCU 24A-9, SCU 33-5, and SCU 21-3 were removed from the list while two wells SRU 12-15 and SRU 21- 33WD were added to the list. RECEIVED APR - 1 1994 Naska 0il & Gas Cons. Commission ~chorage Mr. Joseph A. Dygas March 31, 1994 Page 2 As was the case last year, SCU 43-4WD is not included on the proposed TA list since it is a standby water disposal well used only seasonally.

Dygas Bureau of Land Management Alaska State Office 222 West 7th Avenue Cf 13 Anchorage, AK 99513-7599 Re: 1993 Sundry Notice Request for TA Wells in S.wansonRiver:Fielc[ · Dear Mr. Dygas: Attached is a Sundry Notice, requesting approval to temporarily abandon ('FA) 31 wells in the Swanson River Field for a period of 12 months. This Sundry Notice is being submitted to comply with 43 CFR 3162.3-4, paragraph (c) of the Bureau of Land Management Regulations. As shown on the .Sundry Notice, we are requesting that the 12 month approval period for the proposed TA wells coincide with the Plan Period of the Twenty-Ninth Plan of Development and Operations for the Swanson River Field; i.e. April 1, 1993 to March 31, 1994. These concurrent time periods will greatly simplify future TA Sundry Notice and Plan of Development and Operations preparation. Two information sheets are attached with this Sundry Notice request. Attachment 1 lists the proposed TA wells using the same format as submitted last year by ARCO. The two general categories are shut-in wells being held for evaluation for current uses or disposition and wells being held for future uses under field blowdown. Attachment 2 gives a brief explanation for each well that has been added or removed from the proposed Temporarily Abandoned List. Two wells, SCU 243-8 and SCU 21-8 were added to the list while three wells, SRU 21-22, SRU 12A-14 and SRU 211-15 were removed from the list. REEEIV'ED MAR 2 5 199,~ Alaska 0il & Gas Cons. CommisSiOn Anchorage Mr. Joseph A. Dygas March 18 Page 2 As was the case last year, SCU 43-4WD is not included on the proposed TA list since it is a standby water disposal well used only seasonally.

This Sundry Notice is being submitted to comply with Chapter II, Section 3162.3-4, paragraph (c) of the Bureau of Land. Management Regulations. All 32 wells are expected 'to be shut-in for a period of at least 30 days during 1992. Several information sheets are attached with this Sundry Notice request. Attachment 1 lists the proposed TA wells and separates them into the following five categories: Shut-in wells under evaluation for: . rate potential, permanent abandonment (P & A), and shallow gas sand potential and 'Hemlock Only abandonment. RECEIVED DEC ;5 1 199t Alaska Oil & Gas Cons. Commission Anchorage Mr. J. A. Dy gas Page 2 December 27, 1991 Shut-in wells until field blowdown, including: 4. Hemlock producers, and 5. wells with future shallow gas potential in which the Hemlock has been abandoned. The fifth category shown above is a new addition to this year's TA listing. This grouping is for the wells in 'which the Hemlock has been abandoned but the wellbore is being maintained for possible future shallow gas production. Four wells from last year's TA list were moved into this category. Attachment 2 gives a brief explanation for each well that has been added to or removed from the 1991 Temporarily Abandoned List (Ref: our letter of 12/28/90). Eight wells, $CU 12A-4, SCU 21-8, $CU 23B-3, SCU 43A-4, SCU 13-9, $RU 212-10, SRU 21-22 and $RU 212-27, have been .added while two wellS, $RU 21-15 and SRU 314-27, have been removed from the previous TA List. Attachment 3 is a list of shut-in Wells that are not included in the '92 TA listing. Two of the wells mentioned above, SRU 21-15 and SRU 314-27, are not included because they are scheduled for P & A in the first quarter of 1992. This work is being done as part of the '91-'92 Swanson River Plan of Development. Also included in Attachment 3 is SCU 43-4WD, a standby water disposal well which is only used seasonally.

The proposed intervals lie within the H1 (10,488 - 10,508' MD and 10,513 - 10,518' MD) and will be shot using a 2-1/8" hollow carrier perforating gun. Plans are to initially shoot these intervals using only limited shot density perforations (6 holes total). If subsequent testing indicates that the H1 contains low GOR production potential, these intervals will be re-perforated at full shot density (4 JSPF). With your approval, we would like to begin this work as soon as possible. If you have any questions, please contact Carol Baker at 263-4643. Sincerely, T. S.

TN..R.9W.'. ii I ii I -- II I SWANSON RIVER UNIT Soldotna Creek Unit, Well # 21A-4 Summary of Proposed Work ARCO Alaska Inc. proposes to plug back the existing perforations in the Hemlock Sand, Unit # 5 of Well SCU 21A-4 with a sand plug. If isolation is not achieved with the proposed sand plug, a cement plug may be placed above the H5 sand with either a coiled tubing unit or a dump bailer. Once isolation of these sands is achieved, we propose that the Hemlock Sand, Unit #2 be perforated with 15 feet of 2-1/8" Hollow Carrier Steel guns. A detailed operations program is attached, but please note the following: 1.) The well is currently shut in because of inefficient (High GOR) production. 2.) 3.) 4.) The static reservoir pressure in this area of the field is approximately 4650 psi. The well will have at least 500 feet of crude oil on top of the interval that is being pedorated. The wireline BOP's (see attached diagram) are rated to 5000 psi. RECEIVED MAR 2 ~ 19,8,3 Alaska Oil & 6as Cons. Commissior~ Anchorage SCU 21A-4 Plug Back and Perforate Objective: Plug back the existing high GOR H5 perforations with a sand plug and perforate additional pay in the H2. Procedure: 1. MIRU and pressure test pumping equipment. . Establish pump in rate down the tubing with 5-10 Bbls of lease crude at 2-3 BPM. . . . Add 800 lbs. of 100 mesh sand to lease crude via a cementing tub at 2-3 #/gal. concentration while pumping down the tubing at 2-3 BPM. Include two sacks of silica flour and two sacks of 100 mesh sand in the slurry to contaminate the pack. Flush the leading edge of the slurry to the tubing tail with lease crude and shut down pumping. Wait one hour for the sand to settle and proceed with step 5. RIH with a GR/CCL and tag fill. Repeat steps 3 and 4 if necessary, attempt to place at least 20' of sand above the top perf at 10,638' MD. Make a tie-in log for perforating. 6. Test plug for isolation by bleeding pressure off of tubing. . . . Shoot fluid level on tubing prior to perforating to ensure at least 500' of fluid over the guns. Perforate the H2 interval frOm 10,534'-10,550' with 2-1/8" HSC guns at 4 JSPF. 2.60" gauge ring run on 2-14-88. Initiate production on an 18/64" choke. Monitor well for asphaltene and solids production. Gauge well daily for the first week. RECEIVED ~I~AR 2 5 19~$ 5 Alaska 0il & Gas Cons.

Dygas, Branch Chief United States Bureau of Land Management Post Office Box 230071 Anchorage, Alaska 99523 Dear Joseph: Attached is a Sundry Notice requestin'g approval to temporarily abandon 39 wells in the Swanson River Field for a period of 12 months. This. sundry is being submitted to comply with Chapter II, Sec. 3162.4, paragraph C of the Bureau of Land Management Regulations. All 39 of the wells mentioned in the attached Sundry Notice are expected t,o be shut-in for a period of at least 30 days. The 39 wells listed in Table #1 were identified during our recent review of the status of all wells in the Swanson River Field. These wells have been put into four categories' 1. Evaluate for rate potential 2. Evaluate for plug and abandon/future utility 3. Shut in - inefficient production 4. Shut in - save for blowdown Wells. in Categories #1 and #2 are currently under evaluation to determine their final disposition. Wells in Categories #3 and #4 are wells with little short-term usefulness, but wells that do have some long-term utility. If you have any questions about this Sundry Notice request, please contact me at 263-4299. Sincerely, H. F. Blacker Regional Engineer Cook Inlet/New Ventures HFB: JWR' ch: 0006 Attachment cc' C.V.

Gas may be encountered after packers are released,~hile cleaning out the 7" pri6r to abandonment and while redrilling. Shut in tubing pressure is approximately 3000 psi. Care must be exercised not to swab the well ~hile tripping or pulling production equipment. B. Extreme caution must be exercised while redrilling due to the possibility of high pressure water entries. The first 100 feet of int&~val"to be ~edrill&d is normally drilled with 98 pcf mud. The programmed mud weight of 77-79.pcf will overbalance a 5350 psi pressure by 175-320 psi. 'C. A mud weight of 77-79 pc~ should minimize potential for lost circu- lation while drilling the Hemlock. However, LCM should be kept on hand at all times. . D. Any kicks should be handled by normal procedures. All personnel should be made aware of these methods and care must be exercised at all 'times. The hole is to be kept full at all times. 2. Maximum anticipated formation pressure' A. 5350 psi in the "G" at window depth~ 10,340 feet. B. 4600 psi in the }temlock. Top liemlock 10,480 feet. 3.
