Plug and Abandonment Operations <br />On September 23, 2013, RRWS arrived on location. The location was prepared for the <br />abandonment operations, and the well head was readied to accept the diverter and cementing <br />equipment. Other equipment was gathered in preparation for cementing operations. <br />Cement Plug No. 1: On September 24, 2013, the RRWS crew was onsite at 07:30 hours. The <br />hoses and valves for cementing were hooked up while waiting for a winch truck to move the <br />water tank to location. The winch truck arrived at 09:00 and promptly moved the water tank. <br />The tank was partially filled with 143 barrels (bbls) of water (two truckloads). The well was <br />circulated clean with returns to surface for about five minutes, after which returns were lost. <br />Pumping was halted to avoid pumping too much water into the wellbore. The water tank and <br />truck were re- filled for cement clean up. NW Ready Mix delivered 4 cubic yards of cement to <br />the site at 14:00 hours (21 sacks of Portland cement per yard). The cement was poured into 2 <br />plastic tubs and pumped downhole with the bottom of the pipe at 1,860 feet MD GL. Fifteen <br />joints of drill pipe were pulled out of the hole and laid down. The pump and pipe were <br />circulated clean; the equipment was laid down and the pipe was cleaned. The tank and truck <br />were re- filled for operations on the following day. <br />Cement Plug No. 2: On September 25, 2013, RRWS was onsite at 07:30 hours and warmed up <br />the equipment. RRWS ran drill pipe into the hole and tagged the top of Cement Plug No. 1 at <br />1,700 feet MD GL. The pipe was pulled back to 1,688 feet MD GL in preparation for the second <br />plug. NW Ready Mix was notified and delivered the cement (7 cubic yards mixed at 19 sacks <br />per yard with 15% fly ash additive) at 09:10 hours. An accelerant (1% CaCI) was added to the <br />cement onsite (in the truck) prior to placement. The cement was poured from the truck <br />continuously into a plastic tote through a screen of expanded steel to maintain smooth <br />consistency of the cement. The cement was pumped continuously downhole until the truck <br />was empty. RRWS started pumping cement at 09:25 hours and finished pumping the cement <br />20 minutes later. A cement sample was taken at the beginning of the pour. The pump was <br />hooked up to the water tank and was pumped clean, with waste water going into the pit. While <br />the pump was being cleaned, the crew pulled out 25 joints of drill pipe to clear the calculated <br />top of cement. When the pump was clean, the water was hooked to the drill pipe annulus and <br />reverse circulated through the drill pipe remaining in the hole to clean it of cement. The pipe <br />used in cementing operations, hoses and plastic tub were cleaned for the next cement plug. <br />While waiting on cement to set, the driller looked at the next two P &A well locations (90 -2 and <br />88 -1). <br />Cement Plug No. 3: The top of Cement Plug No. 2 was tagged at 1,182 feet MD GL. Cement <br />Plug No. 2 provided 518 feet of cement in the hole. Approximately 700 feet of cement plug - <br />back was anticipated with the second plug. Another cement plug was planned. NW Ready Mix <br />arrived onsite at 15:10 hours on September 25`n and another 7 yard batch of cement for the <br />third plug (identical to plug number 2) was pumped downhole. The cleanup was completed as <br />above and operations were completed at 16:30 hours. <br />Daub & Associates, Inc. Page 2 of 3 1 -3A P &A Report <br />
