Plugging and Abandonment <br />On October 2, 2013 RRWS arrived on location. The location was prepped for the abandonment <br />operations, and the well head was readied to accept the diverter and cementing equipment. <br />Other equipment was gathered in preparation for cementing operations. RRWS was then <br />directed by NSI personnel to move the rig to another well location. <br />On October 16, 2013 RRWS moved back onto location and rigged up over the 90 -2 to conduct <br />fishing operations. A video log run in June of 2012 showed a possible sampling pump in the <br />hole at 1,801 feet below ground level. The fabricated fishing tool was a 3.5 inch outside <br />diameter (OD) steel pipe with a mule shoe cut onto the end and wire rope welded inside to <br />grab and hold junk. RRWS ran in with the fishing tool and initially tagged something at a depth <br />of 1,807 feet below ground level (BGL). The Driller continued and tagged something hard at <br />1,811 feet BGL. The string was rotated slightly using power tongs, and the string dropped <br />approximately 6 inches. The string was worked up and down, and the driller pulled <br />approximately 5,000 pounds over string weight. The fishing tool was then pulled out of the <br />hole. The junk retrieved consisted of approximately ten feet of % inch stainless steel tubing <br />with two fittings. RRWS shutdown for the day. <br />On October 17, 2013 RRWS ran in the 2 3/8 inch tubing open ended to determine if any <br />additional junk remained in the hole. The tubing stacked out at a depth of 1,813 feet BGL, and <br />was tripped out of the hole. RRWS tripped back into the hole with the fishing tool, worked the <br />fish at 1,813 feet BGL when the string dropped slightly and was on the fish. RRWS pulled out of <br />the hole and discovered that the tool was empty. RRWS shut down for the day. <br />On October 18, 2013 RRWS set up to fish and cement. The driller ran in the hole with a new <br />fishing tool with a cut -lip junk basket. The tool tagged at a depth of 1,813 feet BGL, and the <br />driller worked the string to get over the fish. RRWS then reverse circulated fresh water while <br />sitting on the fish. The fluid level was approximately 550 feet, therefore we should have seen <br />returns after 5 bbls of freshwater pumped. The driller pumped 50 bbls of fresh water with no <br />returns. After breaking the connection at the pump, a strong vacuum was noted, indicating the <br />hole was draining rapidly. The 2 3/8 inch pipe string and fishing tool were pulled out of the <br />hole, and the fishing tool was empty. The decision was made to pull out of the hole, set a <br />bridge plug above 1,811 feet BGL, perforate, then cement to surface <br />On October 19, 2013 RRWS and Jet West rigged up to run a video log, set a bridge plug, <br />perforate the casing and then cement to surface. The video log showed the fluid level at a <br />depth of 537 feet BGL, casing in good condition was noted, with an unknown bridge at 1,810.5 <br />feet BGL. The nature of the fish in the hole and the casing damage could not be visually <br />assessed. Jet West pulled the camera out of the hole and ran in the bridge plug. The cast -iron <br />bridge plug (CIBP) was set at 1,800 feet BGL due to the severe dogleg below 1,800 feet, and the <br />location of a casing collar at 1,806 feet BGL. A two stage slick perforation gun was run into the <br />well, and the 4.5 inch casing was perforated at 550 feet BGL and 275 feet BGL. Each interval <br />was perforated with 4 — % inch holes at 90° phasing. Jet West was then rigged down. RRWS <br />Daub & Associates, Inc. Page 2 of 3 5H Plug and Abandonment Report <br />
