the existing 6H Pad to minimize surface disturbance. The 10H -1V well was drilled to <br />penetrate near the end of the 10H -I injection well cavity in an attempt to restore /improve <br />circulation to the 10H solution mining interval. The 1OH -1 well was previously <br />interconnected with a horizontal recovery well (10H -R), for solution mining and recovery <br />of nahcolite from the UBB. The 10H -I well was recompleted to clean out the slotted shoe <br />joint with a work -over rig subsequent to the completion of the 10H -1V well. <br />The drilling contractor was Capstar Drilling Inc. (Capstar), headquartered in Casper, <br />Wyoming. Capstar used two crews per day working twelve -hour shifts from 06:00 hours to <br />18:00 hours, and 18:00 hours to 06:00 hours, respectively. A tool pusher was onsite and <br />available 24 hours per day. The Rig #314 was used for all drilling operations on this well. <br />The directional drilling contractor was Scientific Drilling, Inc. (SDI), operating out of Grand <br />Junction, Colorado. SDI used two crews per day. Each crew consisted of a directional <br />driller and a monitor - while - drilling (MWD) person, working a twelve -hour shift from 06:00 <br />hours to 18:00 hours, and 18:00 hours to 06:00 hours, respectively. <br />The drilling consultants were Scott Claussen, Curt Claussen and Kelly Claussen of Claussen <br />Consulting, Inc. from Grand Junction, Colorado. The mud engineer was Hamm R. Collins of <br />Marquis Alliance Energy Group USA from Denver, Colorado. Two geologists representing <br />Daub and Associates, Inc. (Daub) from Grand Junction, Colorado, were on -site for geologic <br />consulting and monitoring of the slant well drilling operations. The Daub geologists <br />ensured that the intermediate casing was set in the L5 Zone B/C bed prior to drilling out <br />into the UBB and that connection was made with the 10H -I solution mining cavity. The <br />Daub personnel gathered appropriate information, data and reports pertaining to the <br />drilling activities in order to produce a comprehensive well report to be submitted after <br />the well completion. <br />Daub & Associates, Inc.
