Specific locations and further details are listed on the attached. These applications, together with the one well application we have already submitted and the four we plan to submit during the next month, comprise an evaluation program Chevron is pursuing during 1989. Our objective is to determine whether the coal beds underlying our property are capable of producing gas in economic quantities. We hope to be able to share more of the details of our planned drilling program with you at the meeting on June 5. Per conversations between Glen Hartman of your office and Jan Watson, we plan a presentation and discussion of our plans for 4:00 p.m., Monday, June 5. We are looking forward to working with you on this evaluation project. RAF:maw Attachments Sincerely, /- D. F. Forsgren A?

Inc„ (hereinafter "Chevron"), its agent's, contractors, agricultural lessees and employees, of the right to use that certain private road crossing land ("Land") owned by GOEC in Sections 26, 35 and 36, Township 5 South, Range 98 West, and in Sections 4, 9 and 10, Township 6 South, Range 98 West, 6th P.M., Garfield County, Colorado, This License granted hereby is for the sole purpose of giving Chevron limited access to Chevron's property for oil and gas exploration and development up Clear Creek in Twps. 4, 5, and 65, Rges. 98 and 99W, Garfield County, Colorado. It is understood between GOEC and Chevron that Chevron's use of the private road will be compatible with the use of said private road by GOEG's personnel, it's agents, contractors and agricultural lessees. GOEC shall not be required or obligated to make any changes, alterations, additions, improvements or repairs in, on or about the private road or the Land, or any part thereof, during the term of this License. Chevron accepts the private road in its present condition as of the date of this License and Chevron agrees to maintain the road during its use to the condition of the private road as of the date hereof. The term of this License shall be one (1) year from the date hereof, unless sooner terminated or extended pursuant to the terms hereof. It is expressly understood and agreed that either party shall have the right to terminate this License by giving written notice to the other party thirty (30) days prior to any anniversary date of this License of its intention to so terminate this License. This License and the terms thereof shall cease, terminate and end at 12 midnight of the day preceding the anniversary date following the written notice to terminate. Thereafter GOEC may take possession of the private road and Land and any and all parts thereof, without being liable for damages to Chevron, and GOEC is thereby free, clear, and discharged of all obligations under this License including all rights of Chevron hereunder.

CLASS III BLOWOUT PAEVENTER STACK: The Class III preventer stack is designed for drilling or workover operations. It is composed of a single hydraulically operated annular pre - venter on top, then a blind ram preventer, a drilling spool, and a single pipe ram preventer on bottom. The choke and kill lines are in- stalled onto the drilling spool and must have a minimum internal diameter of 2". All side outlets on the preventers or drilling spool must be flanged, studded, or clamped. An emer- gency kill line may be installed on the wellhead. A double ram preventer should only be used when space limitations make it necessary to remove the drilling spool. In these instances, the choke manifold should be connected to a flanged outlet between the preventer rams only. In this hookup, the pipe rams are considered master rams only, and cannot be used to routinely circulate out a kick. The Class III blowout preventer stack is shown to the right in Figure 11J.4.

CLASS 111 CHOKE MANIFOLD The Class 111 choke manifold is suitable for Class 111 workovers and drilling operations. The Standard Class III choke manifold is shown in Figure 11J.8 below. Specific design features of the Class ill manifold include: 1. The manifold is attached to a drilling spool or the top ram prevenler side outlet. 2. The minimun internal diameter is 2" (nominal) for outlets, flanges, valves and lines. 3. Includes two steel gate valves in the choke line at the drilling spoof outlet. The inside choke line valve may be remotely controlled (HCR). 4. Includes two manually adjustable chokes which are installed on both side of the manifold cross. Steel isolation gate valves are installed between both chokes and the cross, and also downstream oI both chokes. 5. Includes a blooey line which runs straight through the cross and is isolated by a steel gate valve. I� 6. Includes a valve isolated pressure gauge suitable for drilling service which can display the casing pressure within view of the choke operator. 7. Returns through the choke manifold must be divertible through a mud -gas seperator and then be routed to either the shale shaker or the reserve pit through a buffer lank or manifold arrangement. 8. If the choke manifold is remote from the wellhead, a third master valve should be installed immediately upstream of the manifold cross.

BOP CLOSING EQUIPMENT A. General Requirements The accumulator system and pumps must be of adequate capacity for the BOP stack in use. The system must hold'pressurewithout leaks or excessive pumping and should maintain enough pressure capacity reserve to close the preventers with the recharging pumps turned off. These pumps are designed to charge the accumulator within a reasonable time period and maintain this charge during preventer operations, Chevron's design base for surface accumulator capacity is governed by MMS regulalion,Order 30 CFR Part 250.56 (d), which stales that all blowout preventer systems shall be equipped with: Minerals Management Service Sizing Guidelines "A hydraulic actuating system that provides sufficient accumulator capacity to supply 1.5 times the volume necessary to close and hold closed all BOP equipment units with a minimum (remaining) pressure of 200 psi (1,400 kPa) above the precharge pressure without assistance from the charging system. An accumulator backup system which shall be automatic, supplied by a power source independent from the power source to the primary accumulator charging system, and possess sufficient capacity to close all blowout preventers and hold them closed. The above stated MMS regulation is equivalent to sizing a 3000 psi accumulator with enough capacity to close the annular and all ram preventers one time, with the pumps out of service, while maintaining a minimum remaining operating pressure 011500 psi. This equivalence is shown on the next page. This demanding base using a 50% safety factor is recommended by Chevron because it provides complete replenishment of fluid in "close" lines at the time preventers are activated. The safety factor also allows for foss of fluid capacity due to "fnterflow" in the four-way valves and possible loss through the packing of the preventer units. A less demanding base is not recommended, but may be used with Class 11 stacks, provided prior management approval has been obtained. Requirements vary with the size of preventers and are principally controlled by the annular preventer requirements. Opening/closing volume tables provide the necessary information to calculate individual require- ments as to accumulator size needed. Hydraulically operated choke and kill line valves require added fluid capacity. 11 must be remembered that only one-half to two- thirds of the accumulator bottle is liquid filled when fully charged, depending on the unit.

See Exhibit A. We do not plan to change, alter or improve upon any existing state or county roads. B. Travel northwest from Debeque on County Road 204 to the Roan Creek Community Center. Turn right onto County Road 211 and follow to end of County road at gate near Mr. Hiner's ranch. After passing through the gate, travel approximately, 4 miles to access into welisite. The wellsite lies adjacent to the road on the right. 2. PLANNED ACCESS ROADS See Topographic Map "A". The proposed location for Chevron 7-27E lies adjacent to the existing road. No gates, cattleguards, or fence cuts will be necessary. Turnouts will not be required. 3. LOCATION OF EXISTING AND/OR PROPOSED FACILITIES A. See Exhibit A. There are no wells within a one mile radius of the proposed well. B. Installation of production facilities will be addressed at a later date if the well is a producer. C. Disturbed areas no longer needed for operations will be graded back to as near original state as possible. Drainage channels will be returned to original state and the areas will be reseeded. D. A blooie pit 8'x10'x5' deep will be constructed approximately 150' from the center hole as shown on Exhibit C. A line will be placed on the surface from the center hole to the burn pit. The pit will be fenced on four sides to protect livestock. 5. LOCATION AND TYPE OF WATER SUPPLY A. Water will be supplied to the location by truck from sources of surface water in the area. C_ SOURCE OF CONSTRUCTION MATERIALS A. All construction materials needed for this location will come commercially from the Grand Junction, Colorado area. 7. METHODS FOR HANDLING WASTE DISPOSAL A. Cuttings will be settled out in the reserve pit. The reserve pit will be lined. The pit will be fenced with a 32" - 46" woven wire to protect wildlife and domestic animals. B. Drilling fluids will be retained in reserve tanks utilizing maximum recirculation during drilling operations. Following drilling, the liquid waste will be evaporated and the remainder worked into the deep subsoil of the pit, and the pit filled in and returned to natural grade. C. In the event fluids are produced, any oil will be retained until sold in tankage and any water produced will be retained until its quality is determined. The quality and quantity of water produced will then determine the necessary disposal procedure. D. Sewage will be disposed of in a 1,000 gallon fiber glass insulated holding tank, which is to be placed in the vicinity of the trailer on the well location. Arrangements have been made for the sewage to be transported from the wellsite to the Town of Debeque, Colorado for disposal in the town disposal system_ The sewage will be hauled by an authorized hauling firm E. Trash will be contained in a portable metal container and hauled periodically to an approved disposal site. F. After the rig has moved from the wellsite, all waste material will be removed to an approved disposal site. 8. ANCILLARY FACILITIES A. One trailer will be placed on the well location to house the tool pusher. An office site located off the access road to the location for Chevron 4-28H will contain 2 trailers for office facilities and housing for approximately 4 to 8 employees, pipe and equipment storage, fuel for generator and trucks and a parts van. 9. WELLSITE LAYOUT A. Four to six inches of topsoil will be removed from the location and stockpiled. Location of mud tanks, reserve, burn and trash pits, pipe racks, living facilities and soil stockpiles will be located as shown on Exhibit D. B. Pits will not be lined. C. Access to the well pad will be as indicated in Exhibit C. 10. PLANS FOR RESTORATION OF SURFACE A. All surface areas not required for producing operations will be graded to as near original condition as possible and contoured to maintain possible erosion to a minimum. Any rock encountered in excavation will be disposed of beneath backfill to return surface to its present appearance and provide soil for seed growth. B. The topsoil will be evenly distributed over the disturbed areas and reseeded with a seed mixture recommended by Garfield County to avoid introduction of noxious weeds. C. Pits and any other area that would present a hazard to wildlife or livestock will be fenced off when the rig is released and removed. D. Any oil accumulation on the pit will be removed, burned or overhead flagged as dictated by then existing conditions. E. The well will be completed during 1989. Rehabilitation will commence following completion of the well. If the wellsite is to be abandoned, all disturbed areas will be recontoured to the natural contour as is possible. 11. SURFACE OWNERSHIP A. The wellsite and access road will be constructed on Chevron owned surface. The operator shall contact the State O&GCC at (303) 894-2100 between 24 and 48 hours prior to construction activities. 12. OTHER INFORMATION A. The well is located on hilly and sandy/shaley terrain. Vegetation includes mixed desert shrubs and Juniper Pinon. The fauna of the area consists predominantly of mule deer, coyotes, rabbits and varieties of small ground squirrels and other types of rodents. B. Surface use activities other than the oil well facilities consist of livestock grazing. C. There are no known archeological, historic or cultural sites in the immediate area. D. The surface is owned by Chevron. Mr. D. F. Forsgren P. 0.

CLASS HI BLOWOUT RAEVENTER STACK: The Class III preventer stack Is designed for drilling or workover operations. It is composed of a single hydraulically operated annular pre - venter on lop, then a blind ram preventer, a drilling spool, and a single pipe ram preventer on bottom. The choke and kill lines are in- stalled onto the drilling spool and must have a minimum internal diameter of 2". All side outlets on the preventers or drilling spool muss be flanged, studded, or clamped. An emer- gency kill line maybe installed on the wellhead. A double ram preventer should only be used when space limitations make it necessary 10 remove the drilling spool. In these instances, the choke manifold should be connected to a flanged outlet between the preventer rams only. In this hookup, the pipe rams are considered master rams only, and cannot be used to routinely circulate out a kick. The Class III blowout preventer stack is shown to the right in Figure 11J.4.

CLASS III CHOKE MANIFOLD The Class 111 choke manifold is suitable for Class 111 workovers and drilling operations. The Standard Class HI choke manifold is shown in Figure 11 J.8 below. Specific design features of the Class 111 manifold include: 1. The manifold is attached to a drilling spool or the top ram preventer side outlet. 2. The minimun internal diameter is 2" (nominal} for outlets, flanges, valves and lines. 3. Includes two steel gate valves in the choke line at the drilling spool outlet. The inside choke line valve may be remotely controlled (HCR). 4. Includes two manually adjustable chokes which are installed on both side of the manifold cross. Steel isolation gate valves are installed between both chokes and the cross, and also downstream of both chokes. 5. Includes a blooey fine which runs straight through the cross and is isolated by a steel gate valve. 6. Includes a valve isolated pressure gauge suitable for drilling service which can display the casing pressure within view of the choke operator. 7. Returns through the choke manifold must be diverlible through a mud -gas seperalor and then be routed to either the shale shaker or the reserve pit through a buffer tank or manifold arrangement. 8. If the choke manifold is remote from the wellhead, a third master valve should be installed immediately upstream of the manifold cross.

BOP CLOSING EQUIPMENT A. General Requirements The accumulator system and pumps must be of adequate capacity for the BOP slack in use. The system must hold'pressure without leaks or excessive pumping and should maintain enough pressure capacity reserve to close the preventers with the recharging pumps turned off. These pumps are designed to charge the accumulator within a reasonable time period and maintain this charge during preventer operations. Chevron's design base for surface accumulator capacity is governed by MMS regulalion,Order 30 CFR Part 250.56 (d), which states that all blowout preventer systems shall be equipped with: Minerals Management Service Sizing Guidelines "A hydraulic actuating system That provides sufficient accumulator capacity to supply 1.5 times the volume necessary to close and hold closed all BOP equipment units with a minimum (remaining) pressure of 200 psi (1,400 kPa) above the precharge pressure without assistance from the charging system. An accumulator backup system which shall be automatic, supplied by a power source independent from the power source to the primary accumulator charging system, and possess sufficient capacity to close all blowout preventers and hold them closed. The above staled MMS regulation is equivalent to sizing a 3000 psi accumulator with enough capacity to close the annular and all ram preventers one time, with the pumps out of service, while maintaining a minimum remaining operating pressure of 1500 psi. This equivalence is shown on the next page. This demanding base using a 50% safely factor is recommended by Chevron because it provides complete replenishment of fluid in "close" lines at the time preventers are activated. The safety factor also allows for loss of fluid capacity due to "interfiow" in the four- way valves and possible loss through the packing of the preventer units. A less demanding base is not recommended, but may be used with Class II slacks, provided prior management approval has been obtained. Requirements vary with the size of preventers and are principally controlled by the annular preventer requirements. Opening/closing volume tables provide the necessary information to calculate individual require- ments as to accumulatorsize needed. Hydraulically operated choke and kill line valves require added fluid capacity. It must be remembered that only one-half to Iwo- thirds of the accumulator bottle is liquid filled when fully charged, depending on the unit.

CHEVRON #3-17E SEC. 17,T 5S, R 98W GARFIELD COUNTY, COLORADO MULTIPOINT SURFACE USE PLAN 1. EXISTING ROADS A. See Exhibit A. We do not plan to change, alter or improve upon any existing state or county roads. B. Travel northwest from Debeque on County Road 204 to the Roan Creek Community Center. Turn right onto County Road 211 and follow to end of County Road at gate near Mr. Hiner's ranch. After passing through the gate, travel approximately 7 1/2 miles. The well location lies adjacent to the road on the right. 2. PLANNED ACCESS ROADS See Topographic Map "A". The proposed location for Chevron 3-17E lies adjacent to the existing road. No gates, cattleguards, or fence cuts will be necessary. Turnouts will not be required. 3. LOCATION OF EXISTING AND/OR PROPOSED FACILITIES A. See Exhibit A. There are no wells within a one mile radius of the proposed well. B. Installation of production facilities will be addressed at a later date if the well is a producer. C. Disturbed areas no longer needed for operations will be graded back to as near original state as possible_ Drainage channels will be returned to original state and the areas will be reseeded_ D. A blooie pit 8'x10'x5' deep will be constructed approximately 150' from the center hole as shown on Exhibit C. A line will be placed on the surface from the center hole to the burn pit. The pit will be fenced on four sides to protect livestock. 5. LOCATION AND TYPE OF WATER SUPPLY A. Water will be supplied to the location by truck from sources of surface water in the area. 6. SOURCE OF CONSTRUCTION MATERIALS A. All construction materials needed for this location will come commercially from the Grand Junction, Colorado area. 7. METHODS FOR HANDLING WASTE DISPOSAL A. Cuttings will be settled out in the reserve pit. The reserve pit will be lined. The pit will be fenced with a 32" - 48" woven wire to protect wildlife and domestic animals. B. Drilling fluids will be retained in reserve tanks utilizing maximum recirculation during drilling operations. Following drilling, the liquid waste will be evaporated and the remainder worked into the deep subsoil of the pit, and the pit filled in and returned to natural grade. C. In the event fluids are produced, any oil will be retained until sold in tankage and any water produced will be retained until its quality is determined. The quality and quantity of water produced will then determine the necessary disposal procedure. D. Sewage will be disposed of in a 1,000 gallon fiber glass insulated holding tank, which will be placed in the vicinity of the trailer on the well location. Arrangements have been made for the sewage to be transported from the wellsite to the Town of Debeque, Colorado for disposal in the town disposal system. The sewage will be hauled by an authorized hauling firm E. Trash will be contained in a portable metal container and hauled periodically to an approved disposal site. F. After the rig has moved from the wellsite, all waste material will be removed to an approved disposal site. 8. ANCILLARY FACILITIES A. One trailer will be placed on the well location to house the tool pusher. An office site located off the access road to the location for Chevron 4-26H will contain 2 trailers for office facilities and housing for approximately 4 to 6 employees, pipe and equipment storage, fuel for generator and trucks and a parts van. 9. WELLSITE LAYOUT A. Four to six inches of topsoil will be removed from the location and stockpiled. Location of mud tanks, reserve, burn and trash pits, pipe racks, living facilities and soil stockpiles will be located as shown on Exhibit C. B. Pits will not be lined. C. Access to the well pad will be as indicated in Exhibit C. 10. PLANS FOR RESTORATION OF SURFACE A. All surface areas not required for producing operations will be graded to as near original condition as possible and contoured to maintain possible erosion to a minimum_ Any rock encountered in excavation will be disposed of beneath backfill to return surface to its present appearance and provide soil for seed growth. B. The topsoil will be evenly distributed over the disturbed areas and reseeded with a seed mixture recommended by Garfield County to avoid introduction of noxious weeds. C. Pits and any other area that would present a hazard to wildlife or livestock will be fenced off when the rig is released and removed. D. Any oil accumulation on the pit will be removed, burned or overhead flagged as dictated by then existing conditions. E. The well will be completed during 1989. Rehabilitation will commence following completion of the well. If the wellsite is to be abandoned, all disturbed areas will be recontoured to the natural contour as is possible. 11. SURFACE OWNERSHIP A. The wellsite and access road will be constructed on Chevron owned surface. The operator shall contact the State 0&GCC at (303) 894-2100 between 24 and 48 hours prior to construction activities. 12. OTHER INFORMATION A. The well is located on hilly and sandy/shaley terrain.
