each well will be capped. The estimated cost of abandonment is $13,000 per groundwater <br />monitoring well and $5,000 per production well or observation hole. <br />Reclamation of Pyrolysis Zone: At the conclusion of the ElectrofracTM high-temperature test, <br />ExxonMobil will take steps to prevent residual hydrocarbons from migrating to the groundwater <br />system. This may be accomplished by injecting cement-based grout or glue directly into the <br />pyrolysis zone or into the fracture network surrounding it, or some alternative reclamation <br />procedure may be developed and implemented. <br />Air Emissions: Potential air emissions are anticipated to be minor. ExxonMobil will provide all <br />air emission notices and obtain any air quality permits as required. <br />Equipment: The following types of equipment will be required to carry out the experiment: <br />• General truck and/or skid mounted drilling equipment and facilities as required for <br />drilling monitoring wells, production wells and observation/instrumentation holes. <br />• Water tanks and pumps for water used in drilling. <br />• Air compressors used in drilling and hole cleaning. <br />• Small-scale cement mixing and pumping equipment. <br />• Portable electric generators for offices, other facilities, and for energizing the <br />ElectrofracTM heater(s)., <br />• Temperature, electrical, and mechanical sensors and recording equipment. <br />• Transformers for energizing Electrofrac(s)TM <br />• Fluid-handling facilities that may include a gas-liquid separator, liquid storage tanks, <br />liquid pumps (surface and/or downhole), vapor vacuum pumps, a compressor, a sulfur <br />treatment unit, a flare for hydrocarbon gas incineration, and propane storage tanks. <br />• Liquid nitrogen storage and a vaporization unit. <br />• Office trailers (no on-site living accommodations). <br />Personnel: It is expected that, during construction, the maximum number of people working at <br />the site at one time will be 30. However, the maximum number of people working at the site <br />during operations will be approximately 12. <br />Traffic: The proposed experiment will not significantly impact traffic on County Road 215. We <br />anticipate a maximum of 8 passenger vehicles and 2 large haul trucks per day. <br />Financial Warranty: The Exxon Mobil Corporation Financial Warranty currently in place for <br />MLRB Permit No. 80-47 will cover the work described in this application. <br />Verification: <br />The undersigned, executing this Application on behalf of Exxon Mobil Corporation, verifies that <br />the foregoing information is true and accurate and commits to the reclamation of lands disturbed <br />11 <br />#1445022 v1 den
