7/29/2014 | Share/consolidate corridors for pipeline ROWs to the maximum extent possible.
Maximize the utility of surface facilities by developing multiple wells from a single pad (directional drilling), and by co-locating multipurpose facilities (for example, well pads and compressors) to avoid unnecessary habitat fragmentation and disturbance of additional geographic areas.
Minimize newly planned activities and operations within 300 feet of the ordinary high water mark of any reservoir, lake,
wetland, or natural perennial or seasonally flowing stream or river.
Locate roads outside of drainages where possible and outside of riparian habitat.
Avoid new surface disturbance and placing new facilities in key wildlife habitats in consultation with CDOW.
Minimize the number, length, and footprint of oil and gas development roads.
Use existing roads where possible.
Combine utility infrastructure (gas, electric, and water) planning with roadway planning to avoid separate utility corridors.
Combine and share roads to minimize habitat fragmentation.
Where possible, consolidate pipeline and existing roadways, or roadways that are planned for development.
Place roads to avoid obstructions to migratory routes for wildlife, and to avoid displacement of wildlife from public to private lands.
Design roads with visual and auditory buffers or screens (e.g., topographic barriers, vegetation, and distance).
Maximize the use of directional drilling to minimize habitat loss/fragmentation.
Maximize use of remote telemetry for well monitoring to minimize traffic.
Phase and concentrate development activities, so that large areas of undisturbed habitat for wildlife remain.
Maintain undeveloped areas within development boundaries sufficient to allow wildlife to persist within development
boundaries during all phases of construction, drilling, and production.
Minimize the duration of development and avoid repeated or chronic disturbance of developed areas. Complete all
anticipated drilling within a phased, concentrated, development area during a single, uninterrupted time period. |
| Traffic control | Form: (02A )
400400234
7/29/2014 | A street sweeper will make routine passes to eliminate muddy roads.
Most likely, CR 215 to the new Town of Parachute bypass road (to avoid going through town) will be used to get to the pad. The Town of Parachute has agreed to this route. Pilot cars will be used to get the larger rig traffic to location.

| Construction | Form: (02A )
400400234
7/29/2014 | Close and reclaim roads not necessary for development, including removing all bridges and culverts and
recontouring/reclaiming all stream crossings.
Structures for perennial or intermittent stream channel crossings should be constructed using appropriately sized bridges or culverts.
Design road crossings of streams to allow fish passage at all flows and to minimize the generation of sediment.
Design road crossings of streams at right angles to all riparian corridors and streams to minimize the area of disturbance to the extent possible. |
| Noise mitigation | Form: (02A )
400400234
7/29/2014 | A sound wall will be constructed around the perimeter of the pad and the frac pad.

| Drilling/Completion Operations | Form: (02A )
400400234
7/29/2014 | Use centralized hydraulic fracturing operations.
Install and maintain adequate measures to exclude all types of wildlife (e.g., big game, birds, and small rodents) from all fluid pits (e.g., fencing, netting, and other appropriate exclusion measures).
Conduct well completions with drilling operations to limit the number of rig moves and traffic.
Flowlines are 2” 1502 steel lines. They are rated to 15,000psi and are pressure tested before each job to the maximum working pressure anticipated, approximately 7,500psi on this pad. The manifold is 3” line rated to 15,000psi which is also pressure tested to maximum working pressure. We will use a choke manifold in front of the primary 4 phase high stage separator. The 4 phase separator is rated for 4000psi and is capable of handling 90 MMcf/day and 13,956 bbls per day with a 1.25” discharge orifice. Gas from the 4 phase separator is sent to sales. Water from the 4 phase separator is sent to the bullet tank (Pneumatic Tank) to “flash” the water before being sent to sealed flowback water tanks and then moved to the frac tanks to be re-used for frac fluid. “Flashing” the water in the bullet tank allows for the pressure to be dropped to near atmospheric and releases any fugitive gas trapped in the water. Any fugitive gas from the bullet tank is sent to flare or the combustor to be burned off, and any fugitive gas that may remain in the sealed flowback tanks will be sent through carbon filters. A sand trap will be used for drillouts; its primary purpose is as a junk catcher to screen out plug parts. The sandtrap intake and outputs are limited by the 2” flowlines. Water from the sandtrap will be sent to the sealed flowback tank.
The flare stack is rated for 98 MMcf/day, propane is used to fuel the pilot light which insures it is ignited at all times.
The average Mesa Verde well is choked to flow at 1-1.2 MMcf/day. We normally complete 1 completion group (4 wells) at a time.
Proven production can be demonstrated with the following pads; GM 44-1, GV 18-23, GV 8-14 and GM 313-12.

| Interim Reclamation | Form: (02A )
400400234
7/29/2014 | Utilize staked soil retention blankets for erosion control and reclamation of large surface areas with 1.5:1 or steeper slopes.
Avoid use of plastic blanket materials.
Restore both form and function of impacted wetlands and riparian areas and mitigate erosion.
Remove well pad and road surface materials that are incompatible with post-production land use and re-vegetation
requirements.
Use only certified weed-free native seed in seed mixes, except for non-native plants that benefit wildlife.
WPX Energy will use certified, weed free grass hay, straw, hay or other mulch materials used for the reseeding and
reclamation of disturbed areas.
Install exclusionary devices to prevent bird and other wildlife access to equipment stacks, vents and openings.
Reduce visits to well-sites through remote monitoring (i.e. SCADA) and the use of multi-function contractors.
Avoid dust suppression activities within 300 feet of the ordinary high water mark of any reservoir, lake, wetland, or natural perennial or seasonally flowing stream or river where possible. |
