trucks to haul water from the pit to the NS waste pond. KLX Energy Services, Inc. (KLX) out of <br /> Parachute, Colorado, provided fishing tools. <br /> Daub & Associates, Inc. (D&A), based in Grand Junction, Colorado, engineered the conversion <br /> and secured the contract. A geologist from D&A was on-site during all phases of the well <br /> conversion, provided field coordination-supervision, and quality control of the conversion <br /> activity. The D&A geologist performed the following duties: <br /> • provided QA/QC of all operations <br /> • maintained a chronological log of daily activities <br /> • coordinated contractor operations <br /> • provided cost tracking and reporting <br /> Well Conversion <br /> On June 30, 2016, Himes mobilized the Portadrill R-7 rig and equipment to well DS-4 from <br /> Grand Junction, CO. The installed water level transducer was removed from the well. The 4.5 <br /> inch steel casing stickup was cut off and a 4.5 inch K55 collar was welded on to allow <br /> installation of the Himes rotating head. <br /> On July 1, 2016 Himes began running into the hole open ended with 2.375 inch pipe to attempt <br /> to tag the bottom of the hole. The 2.375 inch pipe tagged an obstruction in the well at 1,353 <br /> feet GL (anticipated tagging bridge plug at 1,952 feet GL). The tag was reported by the driller as <br /> soft and caused the open ended pipe to torque up and backspin the table nearly one full turn. <br /> The pipe was tripped out of the hole, and several sections of blue transducer cable were <br /> discovered in the mule shoe. A conversation was initiated with NS personnel, and it was later <br /> determined that a transducer with approximately 600 feet of cable was dropped in the well in <br /> December of 2015, which was documented by NS but not conveyed to D&A. KLX was contacted <br /> to provide fishing tools to retrieve the transducer and cable. KLX arrived at the location with a <br /> spear and coil spear but did not have a crossover with the correct thread type due to a <br /> miscommunication regarding the equipment requirements. <br /> On July 2, 2016 KLX provided the correct crossover and Himes made up a fishing BHA consisting <br /> of the KLX 3.625 inch OD coil spear with a 3.875 inch stop ring. The BHA tagged hard at 1,104 <br /> feet GL and could not be worked any lower. The coil spear BHA was tripped out and found to <br /> be empty, however, the green paint on the 3.875 inch stop ring had been completely worn off <br /> and bore evidence of being bound up in the casing. Himes then ran in the hole with the <br /> traditional (inverted Christmas tree) spear with no stop ring and tagged the fish at 1,355 feet <br /> GL. The fish was worked by rotating the pipe and applying weight. Approximately 350 feet of <br /> transducer cable along with the transducer probe was retrieved. It was not known at this time <br /> that there was additional cable in the hole. Himes ran in the hole open ended and tagged hard <br /> at 1,832.2 feet GL and could not get past this depth. It was decided to attempt to tremie gravel <br /> at this point, and attempt to tag the gravel top after each bucket poured was. Three 5 gallon <br /> buckets of crushed and sorted gravel was poured through the tremie pipe at 1,825 feet GL at a <br /> rate of one 5 gallon bucket every 45 minutes. After 3.5 buckets, the bottom tag remained <br /> Daub&Associates, Inc. Page 2 of 5 July 2016 <br />
