There are numerous different versions of wording used for each of the rules that create confusion and inconsistent implementation of well integrity requirements for injection wells when pressure communication or leakage is indicated. In several injection orders, there are no rules addressing requirements for notification and well disposition when a well integrity failure is identified. Wording used for the administrative approval rule in injection orders is similarly inconsistent. The Commission proposes these three rules as replacements in all injection orders: Demonstration of Mechanical Integrity The mechanical integrity of an injection well must be demonstrated before injection begins, at least once every four years thereafter (except at least once every two years in the case of a slurry injection well), and before returning a well to service following a workover affecting mechanical integrity. Unless an alternate means is approved by the Commission, mechanical integrity must be demonstrated by a tubing/casing annulus pressure test using a surface pressure of 1500 psi or 0.25 psi/ft multiplied by the vertical depth of the packer, whichever is greater, that shows stabilizing pressure and does not change more than 10 percent during a 30 minute period. The Commission must be notified at least 24 hours in advance to enable a representative to witness mechanical integrity tests. Well Integrity Failure and Confinement Whenever any pressure communication, leakage or lack of injection zone isolation is indicated by injection rate, operating pressure observation, test, survey, log, or other evidence, the operator shall immediately notify the Commission and submit a plan of corrective action on a Form 10-403 for Commission approval. The operator shall immediately shut in the well if continued operation would be unsafe or would threaten contamination of freshwater, or if so directed by the Commission. A monthly report of daily tubing and casing annuli pressures and injection rates must be provided to the Commission for all injection wells indicating well integrity failure or lack of injection zone isolation. Administrative Actions Unless notice and public hearing is otherwise required, the Commission may administratively waive or amend any rule stated above 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 fluid movement outside of the authorized injection zone.

My thinking is that otherwise, an operator might argue that the Commission can only require the well to be shut in by going through an enforcement action, issuing an order after notice and opportunity for hearing, or meeting the strict requirements for an emergency order under the regulations. The proposed language makes clear that it is a condition of the authorization to inject, that the operator must shut in the well if directed by the Commission after a notification of loss of integrity, etc. »> James Regg <jim regg(aadmin.state.ak.us> 8/25/2004 3:15:06 PM »> Rob -Thanks for the review; here's a redraft after considering your comments.

For slurry injection wells, the tubing/casing annulus must be tested for mechanical integrity every 2 years. The MIT surface pressure must be 1500 psi or 0.25 psi/ft multiplied by the vertical depth, whichever is greater, must show stabilizing pressure and may not change more than 10% during a 30 minute period. Any alternate means of demonstrating mechanical integrity must be approved by the Commission. The Commission must be notified at least 24 hours in advance to enable a representative to witness pressure tests. Well Irate rite Failure and Confinement The tubing, casing and packer of an injection well must demonstrate integrity during operation. The operator must immediately notify the Commission and submit a plan of corrective action on Form 10-403 for Commission approval whenever any pressure communication, leakage or lack of injection zone isolation is indicated by injection rate, operating pressure observation, test, survey, or log.

John McMullen sent this to us, it's an order proposed by the AOGCC to replace the well integrity related language in the current Area Injection Orders. Listed below are comments, not sure who is coordinating getting these in front of Winton/Jim. Overall, looks okay from an Operations perspective. We do have a few comments, but could live with the current proposed language. Note the proposed public hearing date is November 4. The following language does not reflect what the slope AOGCC inspectors are currently requiring us to do: "The mechanical integrity of an injection well must be demonstrated before injection begins, at least once every four years thereafter (except at least once every two years in the case of a slurry injection well), and * before*_** 1 of 3 10/28/2004 11:09 AM [Fwd: Re: [Fwd: AOGCC Proposed WI Lan for Injectors]] return'.ng a well to service following a workover affecting mechanical integrity." After a workover, the slope AOGCC inspectors want the well warmed up and on stable injection, then we conduct the AOGCC witnessed MITIA. This language requires the AOGCC witnessed MITIA before starting injection, which we are doing on the rig after the tubing is run. Just trying to keep language consistent with the field practice. If "after" was substituted for "before", it would reflect current AOGCC practices. It would be helpful if the following language required reporting by the "next working day" rather than "immediately", due to weekends, holidays, etc. We like to confer with the APE and get a plan finalized, this may prevent us from doing all the investigating we like to do before talking with the AOGCC. "Whenever any pressure communication, leakage or lack of injection zone isolation is indicated by injection rate, operating pressure observation, test, survey, log, or other evidence, the operator shall_* immediately*_** notify the Commission" This section could use some help/wordsmithing: "A monthly report of daily tubing and casing annuli pressures and injection rates must be provided to the Commission for all injection wells indicating well integrity failure or lack of injection zone isolation." Report content requirements are clear, but it's a little unclear what triggers a well to be included on this monthly report. Is it wells that have been reported to the AOGCC, are currently on-line and are going through the Administrative Action process? A proposed re-write would be: "All active injection wells with well integrity failure or lack of injection zone isolation shall have the following information reported monthly to the Commission: daily tubing and casing annuli pressures, daily injection rates." Requirements for the period between when a well failure is reported and when an administrative action is approved are unclear. This document states "the operator shall immediately notify the Commission and submit a plan of corrective action on a Form 10-403". If we don't plan to do any corrective action, but to pursue an AA, does a 10-403 need to be submitted? The AOGCC has stated they don't consider an AA as "corrective action". Let me know if you have any questions.

By letter dated December 7, 1988, Union Oil Company of California (Unocal) submitted an application requesting the Alaska Oil and Gas Conservation Commission (the Commission) to issue an order authorizing the disposal of non-hazardous oil waste fluids by injection into Lewis River Well D-1. 2. Notice of an opportunity for a public hearing on January 13, 1989 was published by the Commission in the Anchorage Daily News on December 14, 1988. 3. By letter dated December 28, 1988 Trustees for Alaska and the Alaska Center for the Environment protested issuance of subject disposal order and requested a hearing for Unocal's application. 4. On January 13, 1989, at 11:00 AM AST in the conference room of the Alaska Oil and Gas Conservation Commission, 3001 Porcupine Drive, Anchorage, Alaska, a hearing was held on Unocal's application to dispose of non-hazardous oil field waste fluids by underground injection in .Lewis River Well D-1. 5. The hearing record remained open for ten working days follow- ing notification, to all parties attending the hearing, of the U. S. Environmental Protection Agency's (EPA's) action under 40 CFR 144.7(b)(3)(ii) with respect to Unocal's aquifer exemption application. EPA approved the aquifer exemption by letter dated March 28, 1989. Trustees for Alaska and the Alaska Center for the Environment both testified against the application. Trustees for Alaska submitted a written opposi- tion dated January 13, 1989. The hearing record closed at 4:30 PM, April 11, 1989, without any further opposition to the application being filed. 6. The Commission issued Aquifer Exemption Order No. 3 on March 30, 1989, exempting aquifers lying below a depth of 2300 feet in Unocal's Lewis River Well D-1 and within a circle of one-quarter (4) mile radius around the well. The exemption is for the purpose of Class II underground injection activities only. ~'' • ~ Disposal Injection Order No. 6 May 11, 1989 Page 2 FINDINGS: 1. Trustees for Alaska and the Alaska Center for the Environment have raised questions regarding: 1) requirement for a waste water disposal permit from Alaska Department of Environmental Conservation (ADEC); 2) consistency of activity with the Alaska Coastal Management Program (RCMP) and notification of those agencies with ACMP responsibility; 3) Commission authority to approve activity outside an existing oil and gas unit; 4) D-1 well's integrity and subsequent ability to confine injected fluids to proposed disposal zones; 5) characterization of fluids proposed for disposal; 6) com- patibility of injected fluids with formation and formation waters; 7) extent of radial invasion of injected fluids; 8) processing of fluids proposed for disposal; 9) solid waste disposal; 10) filing of EPA Form 4 (EPA Form 7520-6); 11) applicable procedures for processing UIC permits; and 12) public notice requirements. 2. No ADEC permit is required because AS 46.03.100(d) exempts from ADEC permitting requirements injection projects per- mitted by the Commission under AS 31.05.030(h). 3. Unocal received a conclusive ACMP consistency determination for its surface operations from the Division of Governmental Coordination March 22, 1989. The Commission's regulations provide for control of the proposed subsurface operations, which should ensure that surface impacts will not occur, other than those resulting from the above ground activities which have been permitted by other agencies and which already have been found to be consistent with the ACMP. 4. AS 31.05.030 grants the Commission jurisdiction and authority over all persons and property subject to the state's police powers, regardless of whether the property is "unitized". 5. Unocal's Lewis River Well D-1, an abandoned well, will be entered and completed as an underground injection well. 20 AAC 25.005(b) requires submission of an application for Permit to Drill. Enforcement of 20 AAC 25.412 requires that Lewis River Well D-1 be constructed, and the mechanical integrity demonstrated in a manner that will insure that injected fluids are confined to projected disposal strata. The well must be tested and monitored thereafter for dis- closure of possible abnormalities in operating conditions that may lead to the endangerment of underground sources of drinking water. 6. The Commission finds the fluids proposed for injection under Unocal's December 7, 1988 application are acceptable for disposal into Class II injection wells. • ~ Disposal Injection Order No. 6 May 11, 1989 Page 3 7. Commission regulations do not require that oil field waste fluids injected for disposal be compatible with the formation or formation waters. 8. The Commission finds the proposed volume of injected fluids over the life of the disposal project will not extend beyond a one-quarter (4) mile radius from the well. 9. Enforcement by the Commission of the regulations will insure the requirements of 20 AAC 25.432, requiring regular reporting of injection activities, are met. 10. Disposal of waste solids has no bearing on issuance of an order providing for disposal of oil field waste fluids. 11. The Commission does not require the filing of EPA Form 4 (EPA Form 7526-6) as part of an application for issuance of an order providing for disposal of non-hazardous oil field waste fluids . 12. The Commission's authority to act in this matter is embodied in 40 CFR 147 Subpart C, the Alaska Oil and Gas Conservation Act (AS 31.05), and the Alaska Administrative Code (20 AAC 25.005 through 20 AAC 25.570). 13. The Commission's procedures in matters involving handling of the subject application and posting of public notice fully conforms to the Alaska Oil and Gas Conservation Act, AS 31.05; the Commission's regulations, 20 AAC 25; and 40 CFR 147 Subpart C (which is in consort with those sections of 40 CFR Part 124 that apply to state UIC programs awarded in conformance with Section 1425 of the Safe Drinking Water Act of 1974 as amended). 14. Permeable strata that will accept injected fluids are present below 2300 feet in Lewis River Well D-1. 15. A series of confining strata are present above 2300 feet in Lewis River Well D-1 that will prevent upward movement of injected fluids through the strata into underground sources of drinking water. 16. The strata into which fluids are to be injected should accept fluids at injection pressures which are less than the fracture pressure of the confining strata. CONCLUSION: The stratigraphic sequence present at the well site and mainten- ance of the mechanical integrity of Lewis River Well D-1 will prevent movement of injected fluids into underground sources of drinking water. • r Disposal Injection Order No. 6 May 11, 1989 Page 4 NOW, THEREFORE, IT IS ORDERED THAT: Rule l Non-hazardous oil-field waste fluids may be injected in conform- ance with AAC Title 20, Chapter 25 for the purpose of disposal into the Beluga Formation below the measured depth of 2300 feet in Lewis River Well D-1. Rule 2 Tubing/casing annulus pressure variations between consecutive observations need not be reported to the Commission. Rule 3 Upon request, the Commission may amend any rule stated above so long as the operator demonstrates to the Commission's satisfaction that sound engineering practices are maintained, and the amend- ment(s) will not result in an increased risk of fluid movement into an underground source of drinking water.

And -- and secondly, I have two additional comments to make relating specifically to the UIC permit application. First is that Unocal apparently has not submitted evidence of a surety bond or a financial statement verifying the resources necessary for plugging and abandoning the -- the D-1 well. The bond normally posted with this Commission applies to ail and gas wells or strategraphic test wells, not injection wells.

DISOTELL: My name is Robert Disotell. I am employed by Trustees for Alaska as a technical advisor.. I have some comments' here, and I think they'll be relatively brief, I'll read '.quickly through them. These are 'comments on the UIC permit application technical grounds. One, Unocal has not described those -- those surface facilities necessary for the'' processing of the fluids to be injected into well D-1. Unocal's application should be revised to describe these facilities. 'This will be required for obtained an ADEC waste water permit. Number two, the fluids proposed for injection are not adequately characterized. For example, workover fluids, such as acids and bases are not characterized. Number Three, Unocal has not described the manifesting system which will be employed to trace these fluids from the point of origin to the point of disposal.

CO[nm1SS1G Subject: UNOCAL Lewis River Well D-1 Injection Application UNOCAL Lewis River Well D-1 Aquifer Exemption Application Request for public hearing Dear Commissioner Smith: Trustees for Alaska and the Alaska Center for the Environment hereby file a written protest to, and request a hearing on, the. above applications. Our request is predicated, in part, on the need for a thorough discussion and review of-the following-material _. issues, which, we believe, are crucial. to your determination on whether to grant these applications: 1. UNOCAL apparently has not applied for a-waste water dis- - posal permit from the Alaska Department of Environmental Conserva- tion (ADEC) for these activities. A waste water disposal permit is required pursuant to 18 AAC.72.210, et seq.. - 2. Section 307(c)(3) of the Coastal Zone Management Act of 1972, as amended by 16 USC 1456(c)(3), requires. the applicant to certify that activity affecting land .or water uses in the Coastal - Zone complies with the Alaska Coastal~Management Program. A deter- mination of consistency with the Matanuska - Susitna Borough Coastal -- - Management Program is also required pursuant to AS 46.40. 010. - UNOCAL apparently has not notified the Matanuska-Susitna Borough or the Office of Management and Budget, Division of Govern- mental Coordination of the proposed injection well activity and has not applied for a coastal zone management act certification. The proposed activity is within the Mat-Su coastal zone as shown on Tyonek Map #89 of the Alaskan Coastal Zone Boundaries. 3. UNOCAL apparently has not notified the Office of Management. and Budget, Department of Governmental Coordination of this applica- tion as required by AS 44.19.145(x)(11) .whenever an application includes two or more government agencies. _ 725 Christensen Drive, Suite 4 Anchorage, Alaska 99501 (907) 276-4244 4. The proposed injection well is outside the boundaries of the Lewis River Unit. The legality of injecting unit fluids from production oil and gas wells into an aquifer that lies outside of an existing oil and gas unit is questionable. The Alaska Oil and Gas Commission (AOGCC) may not have the legal authority to approve of such an activity. 5. The requested aquifer exemption is for a well outside the boundaries of the Lewis River Unit. AOGCC does. not appear to have the authority to exempt aquifers outside the boundaries of existing oil and ,gas units. 6. UNOCAL has not addressed the issue of casing cementing as required by 20 AAC 25.252 (b). The integrity of the cementing of this well is particularly critical between 1190 feet and 1270 feet of measured depth. UNOCAL has not demonstrated that the drilling affected zone is sealed in a manner that will prevent the vertical migration of the injected fluids. 7. UNOCAL has not demonstrated that vertical migration of fluids will not occur between any of the various zones whether they are injection zones, hydrocarbon zones, or fresh water zones.. If this well is dependant upon the use of drilling mud for zone seal- ing, then vertical migration will likely occur.. 8. UNOCAL has stated that the maximum surface injection pressure will be 1500 PSI.. This appears to be extremely high considering the nature and depth of the receiving formations as well as the relatively low injection volumes. Injection pressures this high would tend to indicate a tight formation and would result in high pressures adjacent to the well bore. This would promote vertical migration through the drilling affected zone adjacent to 'the wellbore. 9. UNOCAL has not adequately characterized the fluids proposed for disposal. For example, workover fluids such as acids .and bases are not characterized. 10. Some of the fluids listed by UNOCAL pursuant to 20 AAC 25.252(c)(7) for disposal are not eligible for disposal into Class II wells. EPA has provided specific guidance on the fluids eligible for disposal into Class II wells and such fluids as equipment washwaterare not included. 11. UNOCAL has failed to demonstrate for injection will be compatible with the formations, required by 40 CFR 146. 12. UNOCAL has failed to demonstrate for injection will be compatible with the required by 40 CFR 146. 2 that the fluids proposed fluids in the receiving that the fluids proposed receiving formations, as RECEIVED DEC 2 8 1°r:~s Alaska :Oii & Gas Cons. Commission ` ' +' AnCi10~a~'° C: 13. UNOCAL's calculation of the extent of radial invasion is inadequate. The calculation addresses only one interval whereas UNOCAL is proposing injection into one or more of 7 different intervals. 14. UNOCAL has not addressed in sufficient detail the following items, among others, pertaining to the processing of the fluids proposed for disposal: ~a. Transport of the fluids; b. A thorough description of the sources of the fluids; c.~ On site storage and processing of the fluids; d. Metering of the fluids; and e. Record keeping requirements for these fluids. 15. UNOCAL has not addressed in sufficient detail the follow- ing items, among others, pertaining to the physical appurtenances of the injection well and to its physical integrity: a. Well head safety systems; b. Subsurface safety systems; c. Annulus monitoring and vacuum/pressure safety devices and alarms; d. Tubing pressure monitoring and vacuum/pressure safety devices and alarms; and e. Workover plans to ensure the physical integrity of the well. 16. Trustee's takes specific issue with UNOCAL's request for a waiver of the requirement of 20.AAC 25.252 te) . This well has been suspended/abandoned for 7 years and may have serious structural integrity problems. The present condition of the casing, tubing., and cement related to this well is unknown and waivers of those requirements designed to ensure the integrity of the arell are inappropriate. 17. UNOCAL's application does not address a is at the edge of the Lewis River D-1 well pad. this well penetrates the proposed injection zone. water well which It is unknown if 18. UNOCAL's methodology for calculating salinity does not appear to adequately substitute for the laboratory analysis for total dissolved solids, as required by 40 CFR 136. 19. UNOCAL has not addressed .the disposal of solids that may be filtered out or settle in tanks at the well head. This would normally be addressed by a separate solid waste disposal permit application to the ADEC. 20. UNOCAL's application for a Underground Injection Control permit has not been certified to be true. and correct by a respon- sible corporate officer.

UNOCAL apparently has not submitted to AOGCC a filled out EPA Form 4 (EPA Form 7520-6) which is required for all UIC applica- tions at the beginning of the administrative process. This over- sight has led to several other apparent deficiencies in UNOCAL's application including: a. UNOCAL has not submitted a topographic map as required by Form 4; ~b. UNOCAL has not submitted sufficient geologic data on the confining zones as required by Form 4; c. UNOCAL has not submitted sufficient operating data to meet the requirements of Form 4, instruction H; d. UNOCAL has not submitted sufficient data on formation testing to meet the requirements of Form 4, instruction I; e. UNOCAL has not submitted a plugging and abandonment plan; f. UNOCAL has not .submitted a contingency plan for well failures; g. UNOCAL has not outlined a stimulation plan; h. UNOCAL has not described injection procedures; and i. UNOCAL has not submitted evidence of a surety bond or a financial statement verifying the resources necessary for plugging and abandoning the well. 22. AOGCC is not processing UNOCAL's application in accordance with those procedures for UIC permits issued by states as set forth in 40 CFR 124, Subpart A. 23. The public notice published by AOGCC does not conform to the public notice requirement of 40 CFR, Part 124, which provides that any interested member of the public may comment on a proposed permit within the full 30 day notice period. A member of the public may.. also request a hearing at any time during the 30 day period.

The Alaska Oil and Gas Conservation Commission has been requested by letter from UNOCAL dated December 7, 1988 to issue an order in conformance with 20 AAC 25.252. The order would authorize the disposal of non-hazardous liquid waste by injection into Lewis River Well No. D-1. This well would be converted to an injector, and used for disposal of non-hazardous oil field waste fluids by injection into the" upper half of the Beluga Formation at the Lewis River Field, Mat-Su Borough, Alaska. A person who may be harmed if the requested order is issued may file a written protest prior to December 29, 1988 with the Alaska Oil and Gas Conservation Commission, 3001 Porcupine Drive, Anchorage, Alaska 99501, and. request a hearing on the matter. If the protest is timely filed, and raises a substantial and material issue crucial to the Commission's determination, a hearing on the matter will be held at the above address at 11:00 a.m, on January 13, 1989 in conformance with 20 AAC 25.540. If a hearing is to be held, interested parties may confirm this by calling the Commission's office, (907) 279-1433, after December 29, 1988. If no proper protest is filed, the Commission will consider the issuance of the order without a hearing. ~ ~~ ~-- Lonnie C.

Stickney (December 6, 1988). The following discussion presents geologic evidence to show that utilizing multiple sands in the Lewis River D-1 well for water disposal will NOT cause contamination of freshwater aquifers. The relative positions of wells in Lewis River Field are shown on the accompanying index map (Exhibit 1). D-1 is the northernmost well and is located approximately 3,000' northeast of the nearest other well (C-1). Lewis River D-1 is an excellent candidate to use for water disposal because testing has shown that it does not contain commercial gas .and there are several sands suitable for injection which are well-isolated from freshwater aquifers. In the absence of reliable laboratory water analysis data, electric logs provide the means to discriminate between freshwater. sands and those that contain saltwater. Because the total dissolved solids (TDS) content (salinity) of fresh water is relatively low, it is a poor electrolyte that exhibits high resistivity. Conversely,. if the water is more saline, it conducts electricity better and its resistivity is lower. Within the shallowest logged interval at Lewis River Field, high resistivity values recorded on the electric logs indicate that these sands contain fresh water. Focusing attention on Lewis River D-1 (Exhibit 4.1 -- see pocket), the base of this zone (characterized by resistivities well over 100 ohm-m) occurs at a depth of 1,192' MD where it is underlain by a layer of interbedded siltstone and coal over 70' thick. Below 1,270' MD, resistivities in the porous sands generally do not exceed 25 ohm-m, a stark contrast to the interval mentioned above. The difference between these two dramatically different salinity environments leaves no doubt that the intervening layer of siltstone and coal is a very effective permeability barrier. Using standard log analysis techniques, the equivalent salinity of formation water (in ppm NaCl) can be estimated in two ways. One is the Rwa method and the other is the SP method. Both techniques were utilized here and the results are detailed and explained under Methodology (Exhibit 4.3). These methods generally underestimate the actual salinity of formation fluid. Of the two, it is felt that the Rwa method yields the more reliable results because the SP method requires some assumptions that do not strictly apply to the Beluga Formation. Even with these imperfect assumptions,. the salinity values determined with both methods do corroborate each other in showing that the sands below 1,270' MD contain very salty water (cf. Tables 1 and 2). ~ ~ The results of the .Rwa method are presented in Table 1 and also on the log (Exhibit 4.1 -- see pocket). They show that. the equivalent salinities are generally between 4,600 and 11,000 ppm NaCl. Because the Rwa method often tends to underestimate salinity, the true values are probably higher yet. The key point is that this salinity range is several times greater than the 500 ppm limit for potability under 18 ACC 70,020 which effectively rules out these sands as being reasonably expected to supply a public water system. As explained earlier (it is also evident from the accompanying log - Exhibit 4.1 -- in pocket), a freshwater aquifer over 1,000' thick lies immediately beneath the surface in the Lewis River Field area. Numerous lakes and ponds there show that the water table remains at or near the surface all year long. Although Lewis River Field is currently remote from even small population centers, fresh water in this aquifer could be easily tapped by shallow wells should the need ever arise. With continuous recharge from precipitation and snow-melt runoff, this supply of fresh water is virtually limitless. Thus, it would be economically impractical to attempt recovery of drinking water from the underlying saltwater sands. Their depth and the high cost of desalinization would render such an operation economically unfeasible. Water disposal into the deeper saltwater sands would have no affect on potable water quality available at Lewis River Field. Using the mudlog, together with available electric logs and core data, the confining layers were identified are depicted in Exhibit 4.1 (the D-1 log -- in pocket) by shading in and they , the depth track. The main sands targeted for injection in this well occur within the upper half of the Beluga Formation. They are isolated, not only from each other, but the shallowest injectable zone (at 2,562' MD) is isolated from the near-surface freshwater aquifer by over 1,000 cumulative vertical feet of impermeable strata. The specific zones recommended for injection, are indicated below: Planned Injection Zones (MD) Footage Comments 2,562 - 2,596' 34' Correl. sd 300' deeper in C- 2,850' - 2,900' S0' Correl. zone absent in C-1. 2,950' - 2,960' 10' Tested wet in D-1 & absent in C-l. 3,020' - 3,046' 26' Correl. zone very slty in C-l. 3,714' - 3,768' 54' Tested very subcommercial in C-1. 3,873' - 3,893' 20' Tested wet in D-1 & no gas in C-l. 3,907' - 3,918' 11' Tested wet in D-1 & no gas in C-l. Total: 205' A correlation section (Exhibit 4.2 -- in pocket) shows the stratigraphic relationship between Lewis River D-1 and C-1, the nearest well, located 3,000' to the southwest. The top of the Beluga is represented as a horizontal datum and the vertical scale is in hundreds of feet subsea (SS). Proposed injection zones in D-1 are plotted along the left side of the depth track. Test data for both wells is also shown. 2. • • .The generalized dipmeter data, which appears on the cross section, attests to significant structural complexity between the two wells. The opposing dips are consistent with the presence of a structural axis between them. Indications are also strong that each well is cut by a different fault. Although the quality available seismic data is not good, our- latest interpretation shows that Lewis River C-1 and D-1 are situated in separate fault blocks. With these observations in mind, there are two key points: First, the geologic structure between these wells appears to be much more complicated than the simplistic stratigraphic correlation section (Exhibit 4.2 -- in pocket) portrays. Secondly, the zones targeted for injection in D-1 are not in fluid communication with sands in C-1 that are capable of commercial gas production. There is good evidence to show that the various fine-grained facies within the Beluga Formation are impermeable, even when they are of limited thickness. DSTs were conducted on several sands between 2,868 and 4,980' NSD. Although none were found to contain commercial gas, sands that did test some gas are as little as 40 feet deeper than others that tested no gas. These results demonstrate that in this area, the sand-deficient, mixed lithologies between the tested zones do act as effective confining layers. STRATIGRAPHY Glacial: The glacial veneer is characterized by a very poorly sorted mixture of • pebbles, cobbles, sand and interstitial clay. Plant debris in various stages of coalification is also prevalent. At shallow depths, these diverse lithologies tend to be extremely unconsolidated and clay layers are generally discontinuous over large areas. This allows fresh surface runoff to percolate downward unobstructed. As a result, the. electric log signatures normally ascribed to the glacial cover include very high resistivity and a featureless spontaneous potential curve. Very slow acoustic travel time is also typical of such noncompacted sediments. In Lewis River D-1, .the thickness of glacial veneer is uncertain. The Sterling Formation that often underlies the Glacial is so similar as to be indistinguishable from it. Sterling Fm' The lithologic description of the Glacial can also apply to parts of the Sterling Formation. These two units may even be transitional in .places, although a fluvial origin for the Sterling Formation is well-documented (Hayes, 1976). The resulting deposits generally include fining-upward sequences of bedload conglomerates overlain by thick and blocky quartz-rich sands which are often capped by point-bar siltstones and mudstones. Coals are common and represent the vegetative cover of abandoned meanders. Lateral continuity of these lithologies can be quite good in places. These fluvial sediments have been subjected to effective winnowing and abrasion processes that are together responsible for excellent porosity development. 3. In the.. Sterling ~mation, the resistivity cure often shows a blocky character due to the contrast between the generally resistive sandstone beds .and the more conductive, finer-grained interbeds. These lithologies are similarly reflected on the. spontaneous potential and acoustic curves which often makes bed boundaries very distinctive. Unfortunately, in the Lewis River D-1 well, this is not the case. Here, noncompaction limits log resolution such that the contact between the Glacial and the Sterling Formation, if logged, is masked. Under these conditions, fresh connate water can easily. saturate the extremely porous, shallow strata (above 1,192' MD) creating the high resistivity response and a lack of usable character on the spontaneous potential curve. Although proprietary seismic indicates that the Sterling Formation is represented in the Lewis River D-1 well, a clear-cut contact .with the overlying Glacial is not recognizable from available logs. Quite possibly it was penetrated above the logged interval. Whether or not this is true, their cumulative thickness is approximately 1,910' and both units undoubtedly contain freshwater sands to a depth of 1,192' MD. A preoccupation with relative thicknesses of Glacial and Sterling Formation is of little importance. The overriding concern is that the shallow, freshwater zone(s), however subdivided, will remain uncontaminated by the proposed injection program and the above evidence clearly shows this to be true. Beluga Fm• Within the Beluga Formation, sands are thinner and more lenticular than in the overlying units. They tend to be encased in low-permeability siltstones and mudstones as well as being associated with coals of varying thickness. These are the typical interchannel deposits of braided streams from which the Beluga Formation is interpreted to have originated (Hayes, 1976). Thin, low-porosity stringers occur throughout the section which are probably artifacts of diagenetic cementation. At the higher energy levels which are characteristic of braided streams, finer particles do .not have the opportunity to settle out of suspension. Consequently, the resulting sediments tend to be poorly sorted. The "dirty" nature of the Beluga Formation, coupled with the occurrence of hard streaks and coals makes the proposed zones an especially favorable target for injection because permeability should be very low in the finer-grained facies. In Lewis River Field, there is also a coarser conglomeratic facies within the Beluga Formation. These beds have lower porosity than the finer-grained interbeds. The degree to which they are cemented controls their effectiveness as .permeability barriers. Compared to the overlying Sterling Formation, log responses are usually quite dissimilar. The alternation between thin sandstones, mudstone, hard streaks and coal creates an irregular resistivity response. With the predominance of finer-grained facies, the spontaneous potential is also "ragged" and is frequently of little help in delineating bed boundaries. A "ratty" acoustic log response is usually very characteristic of the Beluga Formation. This effect is blurred in the Lewis River D-1 well, presumably by a combination of noncompaction and possibly transitional lithology at the contact with the Sterling Formation. 4. The entire Beluga Formation is approximately 4,086~hick. All of the sands that will be utilized for injection (except as a last resort) are within its upper half. Below 3,950' MD, within the lower half of the Beluga Formation, multiple sands were tested and some even produced subcommercial gas. However, test rates and especially pressures are well below what could ever be considered commercial even under the most optimistic market conditions. Log analysis indicates that other sands below those that were tested also have very minor gas saturation. Since it would be possible to safely utilize any of these sands for water disposal without jeopardizing potential gas recovery, it may be prudent to do so in some cases. This would help ensure the availability of sufficient cumulative injection interval in the event that some of the proposed target sands fail to take fluid as well as we hope. At the low rates and pressures we intend to use for water disposal, even under the most pessimistic conditions, the radius of injection around the D-1 wellbore will be very shallow, even after 15 years, as substantiated by the engineering calculations in Exhibit 8. Tyonek Fm: Although the Tyonek Formation was penetrated by the Lewis River D-I well, it is considerably deeper than any of the proposed injection targets. Thus, its description is not relevant to this application. References• Hayes, J.

It is assumed that NaCl is the dominant salt where specific knowledge of the actual fluid chemistry is unavailable. Resistivity, read from the deep induction curve (Rill), is assumed to be the best approximation of true resistivity of the formation beyond the zone that was invaded by drilling fluids at the time of logging. The formation resistivity factor eliminates the effect of the rock itself from the resistivity measurement so that the resulting value (Rwa) represents only the contained fluid. Rwa values, when corrected to formation temperature, can be used to estimate salinity with a standard nomograph (Exhibit 4.4; Schlumberger, 1978). A straight line through any value for Rwa ton the right stem). and the corresponding formation temperature (on the left stem) will intersect the equivalent salinity (on the middle stem). Since determination of salinity this way involves an exponential of porosity (see Humble formula above), a small error in porosity is reflected as a much larger error in the calculated salinity. Tn Lewis River D-1, an acoustic log provides the only available formation porosity data above 2,395' MD. In shallow sediments that have never been deeply buried, there is only minimal compaction due to normal overburden stress. Under such conditions, acoustic logs grossly overestimate porosity. Adjustment of these abnormally high porosity values for n~compaction is done empirically and is, at best, rather subjective. Hence, the results must be utilized with utmost caution. Lacking confidence in the porosity data for the zones shallower than 2,395' MD in the D-1 well, it was felt that calculated salinities would not be valid and are not shown here. • EXHIBIT 4.3 (continued) • Below 2,395' MD, a neutron-density log was run which provides more reliable porosity data since noncompaction effects are much less dramatic with this tool compared to the acoustic device. Therefore, density porosity (lip) was used in the Humble equation. Because salinity is also a .function of temperature, Rwa must be first be corrected to formation temperature (Tfm) in order to obtain the corresponding salinity. Formation temperatures were determined as shown below and they are represented on the log (Exhibit 4.1) at the appropriate depths. Estimated Mean Surface Temp (MST): 35° F (for Cook Inlet area) Maximum Recorded Temp (Tmax) from FDC: 135° F C~ 8,025' TMD (-7889), i.e., 7,989' BGL where BGL = Below Ground Level Thermal Gradient (TG): TG = (Tmax - MST)/(Depth BGL/100) _ (135° F - 35° F)/(7,989'/100) 1.252° F/100' It is felt that salinity estimation with this method is most valid, so this technique was used for selected sands below 2,500' MD. The results appear on the log (Exhibit 4.1 -- see pocket) and also in Table 1 along with the parameters from which they were calculated. Some sands in this well contain small amounts of gas, yet test results show that even the most prospective ones are subcommercial. The presence of even minor gas is emphasized because it causes Rwa to apoear abnormally high. This must not be ignored because it will result in salinity estimates that are artifically low. SP Methnd: This is a well-known approach which involves calculation of formation fluid resistivity (Rw) using the spontaneous potential (SP) curve from the electric log. In general terms, in a given sand having even a small amount of permeability, the character of the SP curve will reflect the degree of salinity contrast between the drilling mud and the fluid in the formation. n U EXHIBIT 4.3 (continued) Under ideal conditions, using the SP curve to determine Rw (and the corresponding salinity} can work quite well. Most often, however, it must be utilized very cautiously because several factors can suppress SP development. To get reliable results, a sand. within the zone of interest should meet the following criteria: 1) It needs to be sufficiently thick to allow the SP curve to respond to its fullest extent. This maximum excursion of the SP is called static SP or SSP. The minimum thickness required for this to occur is approximately 30 feet. 2) It should also be "clean", i.e., devoid of mudstone or shale because these lithologies interspersed with sand limit SP development. 3) The sand should be 100% water-wet since hydrocarbons can also suppress the SP curve to an unpredictable extent. According to the mudlog and the electric log suite, sands of the Beluga Formation in Lewis River D-1 (between 1,934' and 6,020' MD), contain significant amounts of mudstone. This most certainly limits SP response. Referring to the depths shown in Table 1, most, if not all of those sands fall short of the ideal criteria listed above. Therefore, others with better SP character were chosen for analysis. As was pointed out above, certain sands do have minor, stdcommercial gas saturation which also likely contributes to +~ an SP which is less than the ideal SSP. Several references describe how Rw can be calculated from the SP curve and there are often minor disparities between the various recommended techniques. Usually these differences can be ascribed to the way a particular log analyst chooses to correct for less than ideal conditions in the formation he is analyzing. The service company charts used in this analysis are included herewith as Exhibits 3 through 6. The Schlumberger charts were chosen because they allow the user to make some corrections that are frequently ignored by other general purpose charts. They also circumvent other inappropriate assumptions. Table 2 details the raw data and the values used from each chart.

Tne lower zone is sealed off on the bottom by multiple coals and low-porosity interbeds. Zone 3,907' - 3,918' was perforated for a DST during the initial .drilling phase. Tne zone was shot without a cushion, and no gas or water ever reached surfac=. During the test, surface pressure was 0 psi and showed no buildup. Tne final prognosis concluded this zone is not gas productive. Zone 3,873' - 3,893' was never perforated and does not appear to correlate to a gas Zone in the nearby C-1 well. Zone ~~3 3,714' - 3, 7::8' This zone teas confining lagers at _east 80' thicK above and Bel ow ~t. _.. was not tested during the cry ~ final cri_li ng of the D-1 well but it appears to be correlative to a sang that tested noncommercial in the nearby well C-l. It must be noted that the correlative sand in 0-1 (DST ~~7) flowed only 300 h+CFPD of wet gas through a 3/8" choke ~t 85 psi tubing pressure. These numbers represent an extremely wet gas reservoir with a very limited accumu~ati on and therefore, the sand was squeezed off v;ith 150 sac~;s of cement. • LEWIS RIVER FIELD WELL D-1 • PROPOSED 30" Driven to 33' ' 94# H-40 Casing O 359 245' 2805' 13-3/8" 68# K-55 Csg ®23!

Solids refer to matter suspended or dissolved in water or wastewater. Solids may affect water or effiuent quality adversely in a number of ways. Waters with high dissolved solids generally are of inferior palatability and may induce an unfavorable physiological reaction in the transient consumer. For these reasons, a limit of 500 mg dissolved solids/L is desirable for drinking waters. Highly mineralized waters also are unsuit- able for many industrial applications. Waters high in suspended solids. may be esthetically unsatisfactory for such pur- poses as bathing. Solids analyses are im- portant in the control of biological and physical wastewater treatment processes and for assessing compliance with regula- tory agency wastewater e$iuent limitations. 1. Definitions "Total solids" is the term applied to the material residue left in the vessel after evap- 'Approved by Standard Methods Committee, 1985. .oration of a :sample and its .subsequent drying in an oven at a defined temperature. Total solids includes "total suspended sol- ids," the portion of umtal solids retained by a filter, and "total dissolved solids," the portion that .passes through the filter. .The type of filter holder, the pore size, porosity, area, and thickness of the filter and the physical nature, particle size, and amount of material deposited on the filter are the principal factors affecting separa- tion of suspended. fznm dissolved solids. "Fixed solids" is the term applied to the residue of total, stis~ended, or dissolved solids after ignition for a specified time at a specified temperature. The weight loss on ignition is called "volatile solids." Deter- minations of fined and volatile solids do not distinguish precisely between inorganic and organic matter because the loss on ig- nition is not confined to organic matter. It includes losses due to decomposition or volatilization of sotae mineral salts. Better characterization of e>rganic matter can be made by such tests as total organic carbon (Section 505), BOD :(Section 50~, and COD (Section 508). "Settleable solids" its the term applied to the material settling out of suspension SOLIDS/Total within a defined period, It may include Eoahng material, depending on the tech- nique (209E.3b). 2. Sources of Error and Variability The temperature at which the residue is deed has an important bearing on results, because weight losses due to volatilization of organic matter, mechanically occluded Rater, water of crystallization, and gases from heat-induced .chemical decomposi- bon, as well as weight gains due to oxi- dation, depend on temperature and time of heating. Residues dried at 103 to 105°C may re- tain not only .water of crystallization but >uso some mechanically occluded water. Loss of COz will result in conversion of carbonate to carbonate. Loss of organic matter by volatilization usually will be very fit. Because removal of occluded water a Il1at'ginal at this temperature, attainment ~ constant weight may be very slow. Residues dried at 180 t 2°C will lose +~most all mechanically occluded water. Mme water of crystallization may remain, ~~Y if sulfates are present. Organic fitter maY be lost by volatilization, but e0t completely destroyed. boss of COZ re- s+ilts from conversion of bicarbonates to donates and carbonates maybe decom- ~ partially to oxides or basic salts. Mme chloride and nitrate salts may be lost. ~ Beneral, evaporating and drying water ~P1es at 180°C yields values for dissolved buds closer ~ those obtained through 93 summation of individually determined mineral species than the dissolved solids values secured through drying at the tower temperature. Results for residues high in oil ar grease may be questionable because of the diffi- culty of drying to constant weight in a rea- sonable time. Analyses performed for some special purposes may demand deviation from the stated procedures to include an unusual constituent with the measured solids. Whenever such variations of technique are introduced,. record and present them with the results. 3. Sample Handling and Preservation Use resistant-glass or plastic bottles, pro- vided that the material in suspension does not adhere to container walls, Begs an~_ ysis as soon as possible because of the im- practicality of preserving the sample. Refrigerate sample at 4°C up to analysis to minimize microbiological decomposition of solids. 4. Selection of Method Methods A through E are suitable for the determination of solids in potable, sur- face, and saline waters, as well as domestic and industrial wastewaters in the range up to 20 000 mg/L. Method F is suitable for the determi- nation of solids in sediments,. as well as solid and semisolid materials produced during water and wastewater treatment. 209 A.

The increase u- dish weight represenu the total dissolved solids. The results may not agree with the the- oretical value for solids calculated from chemical analysis of sample (see above). Approximate methods for correlating chemical analysis with dissolved solids are available.' The filtrate from the total sus- pended solids determination (Section 209C) may be used for determination of total dissolved solids. b.

Total Suspended Solids Dried at 103-~ 05°C 1. General Discussion a P-'inciple.• A well-mixed sample is fil- tered through a weighed standard glass- fiber filter and the residue retained on the filter is dried to a constant weight at 103 to 105°C. The increase in weight of the filter represents the total suspended solids. If the suspended material clogs the filter and pro- longs filtration, the difference between the total solids and the total dissolved solids may provide an estimate of the total sus- pended solids. b. Interferences: Exclude large floating particles or submerged agglomerates of nonhomogeneous materials from the sam- ple if it is determined that their inclusion is not desired in the fins] result.- Because excessive residue on the filter may form a water-entrapping crust, limit the sample size to that yielding no more than 200 mg residue. For samples high in dissolved sol- ids thoroughly wash the filter to ensure removal of the dissolved material. Pro- longed filtration times resulting from filter clogging may produce high results owing to excessive solids capture on the clogged filter. 2; Apparatus Apparatus listed in Sections 209A.2 and 2098.2 is required, except for evaporating dishes, steam bath, and 180°C drying oven, In addition: Planchet, • aluminum or stainless steel, 65-mm diam. 3.
