• Detailed Drilling and Completion Plan <br />T-1 (Heater-Producer Test Well) (Figure 8-1) <br />• Drill up to a 24" diameter hole a minimum of 40 feet with at least 5 feet into <br />competent bedrock. Historically, surface casing holes have been 40 feet deep. <br />• Run 40', 94#, J-55 Surface Casing. <br />• Cement with "Neat Cement" to surface. <br />• Rig up diverter and wait on cement a minimum of 4 hours. <br />• Drill out from surface casing with nominal 12 1/4 " diameter bit. Drill to a depth to <br />where the down hole survey tools will not be influenced by the steel surface <br />casing. <br />• Trip out of the hole and put on a mud motor with nominal 12 '/4 "bit. Utilize the <br />motor and surveys to stay vertical to a depth of 1158 feet. Complete directional <br />surveys every 40 feet. <br />• Directionally drill the nominal 12 1/4 " hole to 60 ° inclination (from vertical) at <br />2205 feet MD, 2024 TVD (-top of the Rl) then hold 60° to TMD of 2530 feet. <br />• Open the 12 1/4 " hole to 18" with hole opener. Circulate to clean and condition <br />hole. <br />• Run 11 3/4 " casing to TMD of 2530. Casing will be 759 J-55 to the retort top <br />(-top of the RI) and alloy steel throughout the retort zone. <br />• Cement to surface from the inflatable cement packer at the retort roof. <br />• Wait on cement for 12 hours. <br />• Conduct Mechanical Integrity Test - described below <br />• Condition the hole and install the heater and production assembly. <br />Mechanical Integrity Testing <br />AMSO will employ methods and standards generally accepted in the industry to prove <br />mechanical integrity of its heater-producer well. After the cement has cured, the heater- <br />producer well will be shut in and subjected to air pressure of 1000 psi. This pressure will <br />be held and measured for at least 30 minutes and any pressure change noted. The <br />pressure must be held within 5% to prove the well has mechanical integrity. Mechanical <br />integrity testing will occur every three years or until the heater-producer well is plugged <br />and abandoned. <br />21
