I , AmerAlia, Inc. <br />MWD-1 Drilling and Completion Report <br />the drilling assembly (air-hammer) and supporting surface equipment, drilling of a 10-inch- <br />diameter hole began at about 15:15 oa January 17, 2000. Air mist (3 to 5 gallons per minute <br />[gpm]) was used as a circulation medium. The injection water came from neazby Yellow Creek. <br />After intersecting the water table at approximately 315 feet, groundwater dischazge <br />measurements were taken periodically by Lang personnel. Collection of groundwater <br />geochemical data by Daub & Associates, Inc., personnel began at 975 feet and continued to the <br />bottom of the hole. <br />Because of the significant groundwater flow (approximately 1 15 gpm), drilling of the 10-inch- <br />diameter hole with the air-hammer assembly was suspended at 875 feet on January 18, 2000 <br />(16:02). The drill string was tripped out of the hole and the air-hammer bit was replaced by a <br />98-inch tricone bit. Drilling with the tricone assembly resumed at 04:50 on January 19, 2000, <br />and continued to the intermediate casing point (1,710 feet), which was reached at 01:25 on <br />January 21, 2000. Rotary drill cuttings were described (Table 5) below 950 feet and well-water <br />dischazge samples were collected below 975 feet. Water samples were analyzed on site by <br />personnel from Daub & Associates, Inc. (Table 6). <br />Prior to installing casing, the open hole was geophysically logged by Halliburton, Inc. (Grand <br />Junction, Colorado) from the surface to 1,706 feet. The instrument used was a Dual Laterolog <br />(gamma ray, shallow resistivity, deep resistivity, and surface tension) and Spectral Density Dual <br />Speed Neutron (gamma ray, caliper, neutron porosity, and density porosity). Geophysical <br />logging commenced at approximately 06:30 on January 21, 2000, and concluded at 12:00 on <br />January 21, 2000. A copy of the logs can be found in Appendix A. To date, a cement casing- <br />bond log has not been run in the MWD-1 well. This work will be done at a later time. <br />Following the logging, 1,710 feet of 5-inch OD casing (18 pounds per foot [lb/ft]) was installed <br />and cemented to the surface by the tremie method on January 21-23, 2000. Figure 5 illustrates <br />the completion status of MWD-1 with respect to the casing program. After the cement cured, <br />drilling resumed at about 12:00 on January 23, 2000, and continued to TD (1,731 feet), which <br />was reached at about 16:30 on January 23, 2000. The drilling assembly consisted of a 4'-a-inch <br />tricone bit with air mist (3 to 5 gpm water injection) as the circulation medium. After bottoms- <br />
