FEDERAL 21-20 AND FEDERAL 12-17 WELLS, EMERY COUNTY, UTAH

BACKGROUND:

The Federal 21-20 was drilled and cased in October 1974 and shut in. The well tested 700 MFCF during drill stem testing but was never completed. The Federal 12-17 was drilled, cased, and completed in November 1978 and then it was shut in. The well tested 1.7 MMCFD in 1989 and 2.2 MCFD in 2001. A pipeline was never installed to take gas away from these wells and they changed hands several times until operations were assumed by Walden

Energy Ventures, LLC in February 2006. Walden Energy Ventures, LLC became insolvent in 2015 and the wells were subsequently classified as orphaned. These wells now fall within the Lower Last Chance Wilderness by virtue of the Dingle Act which was signed into law on March 12, 2019. A Minimum Requirements Decision Guide

(MRDG) must be completed and approved prior to plugging these wells.

GEOLOGY:

Onshore Oil and Gas Order No. 2 Section III., G. states that “all formations bearing usable-quality water, oil, gas, or geothermal resources, and/or a prospectively valuable deposit of minerals shall be protected.”

Utah Geological Survey, Bulletin 132, Energy, Mineral, and Ground-Water Resources of Carbon and Emery Counties, Utah published by Utah Geological Survey in 2003 lists the hydrostratigraphic units in Carbon and

8/13/2021 11 Orphan Wells P&A Statement of Work - Utah 2021 4

Emery counties that need to be protected. Table 2 below lists the formations that were penetrated by these two orphaned wells. Per Onshore Oil and Gas Order No. 2, these formations will need to be isolated.

H2S SAFETY HAZARD

MINIMUM REQUIREMENTS REQUIRED BY REGULATION: Onshore Order No.6 – H2S Operations

1. General

a. A specific H2S operations plan for plugging operation will not be required for approval prior to starting work.

b. If H2S is encountered in excess of 100 ppm in the gas stream, the following measures shall be taken:

i. the contractor shall immediately ensure control of the well, suspend plugging operations and obtain materials and safety equipment necessary to bring the operations into compliance with all applicable provisions of Onshore Order No. 6.

ii. The contractor shall notify the authorized officer of the event and the mitigating steps that have or are being taken as soon as possible, but no later than the next business day. If said notification is subsequent to actual resumption of operations, the contractor, shall notify the authorized officer of the date and time that operations were resumed no later than the next business day.

iii. It is the contractor's responsibility to ensure that the applicable requirements of this Order have been met prior to the resumption of operations. Operations will not be suspended pending receipt of a written H2S Drilling Operations Plan(s) and, if necessary, Public Protection Plan(s) provided that complete copies of the applicable Plan(s) are filed with the authorized officer for approval within 5 business days following resumption of operations.

a. Warning System Response. When H2S is detected in excess of 10 ppm at any detection point, all non-essential personnel shall be moved to a safe area and essential personnel (i.e., those necessary to maintain control of the well) shall wear pressure-demand type protective breathing apparatus until the H2S is controlled. Once accomplished, operations may proceed normally.

RECLAMATION

The well pads have filled in with native vegetation and the roads have filled in to two-tracks, therefore, all operations shall be done with high levels of caution to prevent disturbance of the surface that is more than what is necessary. Reclamation will require the removal of all equipment and trash. Depending on damage done during plugging operations, roads may be reclaimed by dragging and roughening the surface to allow the native vegetation to grow in.

RATH 1-A, RATH 1-X & BUCKET WELL EMERY COUNTY, UTAH

These wells were drilled in the early 1950’s by Byrd-Frost, Inc. The Rath 1-X tested 5.2 MMCFD low Btu gas and the Rath 1-A tested 750 MCFD. No pipeline was installed, and the wells never produced except for production testing to the atmosphere. Standard Energy Corporation subsequently purchased the leases and assumed operatorship. In 1989 Standard Energy placed cast iron bridge plugs in the well bores of the Rath 1-A and Rath 1-X above the producing horizons and temporarily abandoned the wells. In 2004 lease UTSL 042322 expired and a Written Order to plug the wells was issued on September 24, 2015. Standard Energy filed for a State Director Review and the Written Order to plug and abandon the wells was found to be justified, however in subsequent years no progress was made on plugging the wells. In June 2019 Mr. Dean Rowell, the president and owner of Standard Energy Corporation, passed away. On December 12, 2019, the Utah State Office of the BLM pulled Standard’s $25,000 plugging bond. Subsequent efforts to contact Standard Energy Corporation have determined that the company is no longer in business. The Bucket Well is in the same section as the Rath 1-X well. All we know is that there is 9 5/8” casing sticking out of what appears to be 12 ¼” surface pipe or an old school swedge. A stone was dropped, and it fell for approximately 16 to 22 seconds. The well is open to the atmosphere with just a bucket as cover.

GEOLOGY:

Onshore Oil and Gas Order No. 2 Section III., G. states that “all formations bearing usable-quality water, oil, gas, or geothermal resources, and/or a prospectively valuable deposit of minerals shall be protected.”

BOOK CLIFFS UNIT 1, GRAND COUNTY, UTAH

The Book Cliffs Unit 1 well was drilled by Great Yellowstone Corporation in the Book Cliffs Field in May 1961 and completed by Gulf Oil in the Dakota formation in July 1961. Operatorship of the well changed several times before Celtic Resources LLC assumed operatorship in February 1991. The operator became insolvent in 2020 and the well became an orphan. In accordance with the requirement of 43 CFR 3162.3-4 (a) (b) and per Section XII of the Bureau of Land Management Onshore Oil and Gas Order No. 1, III.,XII., A., B., this well must be plugged and abandoned (P&A), the equipment must be salvaged, and the wellsite (including the mud pit) location must be reclaimed.

A review of offset wells in the Book Cliffs Unit 1 area does not indicate the presence of H2S in the Book Cliffs Field. Although no H2S has been reported, as a precaution H2S safety measures should be readily available if H2S is encountered, to support well shut in and allow for re-planning of operations to meet requirements as stipulated in Onshore Order No.6 – H2S Operations.

GEOLOGY:

Onshore Oil and Gas Order No. 2 Section III., G. states, “all formations bearing usable-quality water, oil, gas, or geothermal resources, and/or a prospectively valuable deposit of minerals shall be protected.”

Figure 1. below identifies the Stratigraphic units in the Book Cliffs Field and the hydrocarbon and water bearing formations that will need protected, it is taken from Circular 99 May 1999 “A Summary of the Groundwater Resources and Geohydrology of Grand County, Utah” by Chris Eisinger and Mike Lowe published by Utah Geological Survey, a division of Department of Natural Resources. The stratigraphic information in Figure 1. is taken from “Geologic Map of the Moab and Eastern Part of the San Rafael Desert 30' X 60' Quadrangles, Grand and Emery Counties, Utah, and Mesa County, Colorado” by Hellmut H. Doelling published by Utah Geological Survey, a division of Department of Natural Resources, in 2002. Table 2. below lists the formations that were encountered during Well Operations for the Book Cliffs Unit 1, per Onshore Oil and Gas Order No. 2, these formations will need to be isolated.

Lease U-31805:

Book Cliffs Unit 1:

Items to be removed/reclaimed include, but are not limited to:

• Separator

• Storage Tank 400 bbl

• Flow/transfer lines o Wellhead o Separator/treater to storage o Miscellaneous lines

• Guy wire/Rig anchors

• Miscellaneous site debris

The well site is overgrown due to lack of proper site management. There are two small pits on sight (approx.

20’ x 20’ x 5’), associated site operations facilities equipment and miscellaneous debris. The site is reasonably level but may require some compaction to firm up the well site soil for remediation access by heavy vehicles.

Full site remediation will be performed in accordance with appropriate guidelines and COA’s as stipulated in the APD, lease agreement and applicable Federal Guidelines.

PLUGGING RECOMMENDATION:

The contractor will be responsible for determining the cement plugs for the Book Cliffs Unit 1 well listed in Table 7 below. Per Onshore Oil and Gas Order No. 2., III., G. all the known formations listed in Table 2 will need to be isolated.

8/13/2021 11 Orphan Wells P&A Statement of Work - Utah 2021 17

Table 7 Recommended Cement Plug Program:

The target section of the well should be plugged by spotting 226’, from 5220’- 4994’, of cement and squeezing (22 ft3/20 sx) additional cement. The plug should be tested by either tagging the plug with the work string or testing the plug to a minimum pump pressure of 500 psi, with no more than a 10 percent drop during a 15-minute period. If the pressure drop exceeds 10% during the observation period, the COR shall be contacted.

The 8-5/8” shoe and water bearing Castlegate formation will be addressed next. The 5-1/2” by 8-5/8” casing annular space should be isolated by perforating the 5-1/2” casing at 1771’, then placing a cement retainer at 1716’ and squeezing 403’ of cement below the retainer and spotting 348’ of cement on top of the retainer. The contractor should cement 403’ of the annulus area, 50’ below the retainer and 348’ on top of the retainer to ensure the formations are isolated. This plug should be tested by either tagging the plug with the work string, or pressuring to a minimum pump pressure of 500 psi, with no more than a 10 percent drop during a 15-minute period.

The 5-1/2” and 8-5/8” casing should be perforated at 172’ and a surface cement plug of at least 169’ shall be placed in the production casing as well as across all other annuli. The top of this plug should be placed as near to the eventual casing cutoff point as possible. All casing shall be cut-off at the base of the cellar or 3 feet below final restored ground level (whichever is deeper). The well bore shall then be covered with a metal plate at least 1/4-inch-thick and welded in place. The well location and identity shall be permanently inscribed. A weep hole shall be left if a metal plate is welded in place.

RECLAMATION

The well sites must be recontoured to blend with the surrounding landform. All excavations and pits must be dry and free of waste and graded to conform to the surrounding terrain. Salvaged topsoil must be respread evenly over the surfaces to be revegetated. The topsoil site should be prepared to provide a seedbed for reestablishment of desirable vegetation. Site preparation may include gouging, scarifying, dozer track-walking, mulching, fertilizing, seeding, and planting.

Access roads must be reclaimed. Final reclamation includes recontouring the road back to the original contour, seeding, controlling noxious weeds, and may also include other techniques to improve reclamation success, such as ripping, scarifying, replacing topsoil, constructing water bars, pitting, mulching, redistributing woody debris, and barricading.

Seeds of native, perennial species or other plant materials specified by the surface management agency must be used.

BOOK CLIFFS UNIT 3, GRAND COUNTY, UTAH

The Book Cliffs Unit 3 well was drilled by Gulf Oil in the Book Cliffs Field in July 1962 and completed by Gulf Oil in the Dakota formation in August 1962. Operatorship of the well changed several times before Celtic Resources LLC assumed operatorship in May 2001. The operator became insolvent in 2020 and the well became an orphan. In accordance with the requirement of 43 CFR 3162.3-4 (a) (b) and per Section XII of the Bureau of Land Management Onshore Oil and Gas Order No. 1, III.,XII., A., B., this well must be plugged and abandoned (P&A), the equipment must be salvaged, and the wellsite (including the mud pit) location must be reclaimed.

A review of offset wells in the Book Cliffs Unit 3 area does not indicate the presence of H2S in the Book Cliffs Field. Although no H2S has been reported, as a precaution H2S safety measures should be readily available if H2S is encountered, to support well shut in and allow for re-planning of operations to meet requirements as stipulated in Onshore Order No.6 – H2S Operations.

8/13/2021 11 Orphan Wells P&A Statement of Work - Utah 2021 23

Table 7 – Minimum Allowable Cement Plug Program:

The target section of the well should be plugged by spotting 195’ (18 ft3/16 sx) of cement and squeezing (22 ft3/20 sx) additional cement. The plug should be tested by either tagging the plug with the work string or testing the plug to a minimum pump pressure of 500 psi, with no more than a 10 percent drop during a 15-minute period. If the pressure drop exceeds 10% during the observation period, the Contracting Officer’s Representative (COR) shall be contacted.

The 8-5/8” shoe and water bearing Castlegate formation will be addressed next. The 4-1/2” by 8-5/8” casing annular space should be isolated by perforating the 4-1/2” casing at 1840’, then placing a cement retainer at 1785’ and squeezing 322’ (78 sx) of cement below the retainer and spotting 267’ (22 sx) of cement on top of the retainer. The contractor should cement 322’ of the annulus area, 55’ below the retainer and 267’ on top of the retainer to ensure the formations are isolated. This plug should be tested by either tagging the plug with the work string, or pressuring to a minimum pump pressure of 500 psi, with no more than a 10 percent drop during a 15-minute period.

The 4-1/2” and 8-5/8” casing should be perforated at 230’ and a surface cement plug of at least 225’ should be placed in the production casing as well as across all other annuli. The top of this plug should be placed as near to the eventual casing cutoff point as possible. All casing shall be cut-off at the base of the cellar or 5 feet below final restored ground level (whichever is deeper). The well bore shall then be covered with a metal plate at least 1/4-inch-thick and welded in place. The well location and identity shall be permanently inscribed. A weep hole shall be left if a metal plate is welded in place.

MEGADON FEDERAL 1-15, GRAND COUNTY, UTAH

The Megadon Federal 1-15 well was drilled by Megadon Energy Corporation in the Salt Wash Field in February 1981 and originally completed in the Mississippian formation in May of 1981. The original Mississippian completion was abandoned in April 1993 to prepare for a horizontal recompletion in the Mississippian formation. Megadon Enterprises and Saranan Land Company initiated directional drilling operations in May 1993 but were unable to achieve necessary build rates to achieve horizontal well placement and the well was re-completed in Mississippian/Leadville formation in August 1993. The operator became insolvent in 2018 and the well became an orphan. In accordance with the requirement of 43 CFR 3162.3-4 (a) (b) and per Section XII of the Bureau of Land Management Onshore Oil and Gas Order No. 1, III.,XII., A., B., this well must be plugged and abandoned (P&A), the equipment must be salvaged, and the wellsite (including the mud pit) location must be reclaimed.

A review of offset wells in the Megadon Federal 1-15 area does not indicate the presence of H2S in the Salt Wash Field. The Federal 1-15 experienced “Hole making lots of water” while drilling in/near the Wolfcamp Formation Top at 2980’ as reported during drilling operations. Water flows are common in the Salt Wash Field, as offset wells have experienced water flows at varying depths from 50’ to 3500’ and flow intensity documented as high as 50 BPH. Most of the wells in the field were drilled between 1960 and 1985 and have changed ownership multiple times. A recent nearby P&A project located within 1.5 miles of the Megadon 1-15 experienced water flows and substantial casing and tubing corrosion, with heavy scaling present that ultimately resulted in suspension of fishing operations. Tubular corrosion is common for wells in this area and thought to be exacerbated by underground CO2 influxes.

The well makes very little gas production (0.5 MCFPD or less, estimate from DST1 in 1981), with no indication of H2S in the past operations reports, this can be taken as a baseline of what to expect in the well. This was based on a daily drilling and daily completion histories received from Megadon Enterprises Inc in a Well Completion Report dated June 30, 1981 and a review of offset wells with a 1.5-mile radius of the Federal 1-15.

Although no H2S has been reported, as a precaution H2S safety measures should be readily available if H2S is encountered, to support well shut in and allow for re-planning of operations to meet requirements as stipulated in Onshore Order No.6 – H2S Operations.
