5) Drilling Fluids Program: <br />Interval Mud Type <br />0-1300 ft. Air or Aerated Mud or Mud <br />1300 - 2250 ft. Mud or Aerated Mud <br />2250 ft. - TD Saturated bicarb brine or Mud <br />6) Testing, Logging, and Coring: <br />A. Starting at approximately 1400', mud loggers will be taking samples and <br />giving descriptions. <br />B. Once the down hole mud motor package is in operation, a real time /real <br />depth Gamma Ray log will be taken. A LWD (logging while drilling) <br />package will be used to maintain the drilling assembly in the nahcolite <br />seam between the OSMB (oil shale mazker bed) and the R-5 zone. <br />C. Directional surveys will be taken from surface to TD. These directional <br />surveys will include TMD (total measured depth), TVD (true vertical <br />depth), Direction from true north, angle of build, and motor face direction. <br />All directional surveys will be submitted to the BLM. <br />D. No cores or DST's (Drill Stem Tests) are planned. <br />E. Formation Completion Interval- Boies Bed <br />F. No stimulation is required. <br />7) No abnormally high temperatures or pressures are expected during the drilling of <br />this well. Loss circulation zones are expected along the drill course. These will be <br />anticipated and either the mud weight decreased or LCM (loss circulation <br />material) introduced. <br />If circulation is lost, an attempt may be made to drill through the Boise Bed using <br />air and a jet sub to maintain returns. <br />8) Like cavity 6H, cavity 7H will be drilled in a predominately East /West direction. <br />The lateral section of drill hole 7H-2I will be drilled below the OSMB to NOT <br />intersect with cavity 1 A, to a TD of approximately 3600-3650 ft. If excessive <br />fluid losses occur during end of normal drilling, the drilling will be stopped. The <br />hole will be filled and checked for integrity. If it is suspected that lA cavity was <br />intersected, a 50 foot cement plug will be placed in the end of the well bore. Well <br />bore integrity will be tested by filling the hole with water to surface and a fluid <br />level maintained for a short duration of time, not to be less than 30 minutes. <br />
