0754373022 2017-12-07 Casing String Witnessed No Violations The purpose of my inspection was to witness 100 feet of the 26 inch diameter conductor being cemented in a 32 inch diameter borehole. Express Energy drilled the borehole and did not encounter any water during the drilling process. A pre-job safety meeting was held with all personnel on location including Express Energy and CNX Company Man. Following the safety meeting Express Energy pumped 10 barrels of fresh water, 241 sacks of class A cement, and 55 barrels of fresh water were used for displacement. 10 feet of cement was left inside the bottom of the conductor and cement returns were established in the cellar. Cement returns were used to cement the floor of the cellar.
0947794741 2019-01-22 Preliminary Restoration No Violations On this day, I am conducting a preliminary restoration inspection. Site meets 1509.072 (A) Vegetation is established with no substantial erosion. I found the pad gated with signage at the entrance. There are (4) producing wells, (4) gas processing units (GPU), (4) 400-barrel and (1) 100-barrel steel production tanks within polymer lined steel containment, and an Emergency Shutdown (ESD) button is present at the pad entrance. Additionally, concrete barriers surround the perimeter of the wellheads and the GPUs. Each well has identification and annular pressure monitoring devices equipped. The 9.625 inch diameter intermediate casing has a pressure of 100 pounds per square inch (psi), and the 13.375 inch diameter surface casing has a pressure of 900 psi. John Zachwieja, CNX Production Foreman, was notified of the pressure.
1368062898 2017-12-07 Casing String Witnessed No Violations On this day, I am accompanying ODNR Inspector Austin Gutridge. Please refer to his comments for a detailed report. A borehole was drilled to a depth of 100 feet and set a 100 foot conductor with 241 sacks of cement, displaced with 55.74 barrels of water, leaving a 10 foot shoe track in the bottom of the conductor. Cement returns are witnessed at the surface.
1525001023 2018-04-29 Casing String Witnessed No Violations On this day, I am here to witness the 18.625-inch diameter surface casing mine-string cement job with Halliburton Energy Services. The Patterson 803 rig drilled a 24-inch diameter borehole to a depth of 991 feet from a Kelly Bushing of 28 feet. The coal seam was encountered from a depth of 844 feet to 856 feet, without a void. Then, Mikes Power Tong Services attempted to insert 902 feet of 18.625-inch diameter J-55 87.5 lb./ft. casing into the borehole. Before they finished running the casing, they encountered an issue with two of the joints, and it was decided to pull both joints and switch them out for two new ones. As they set through the coal seam, it appeared to be full of water which created the casing to float, so they loaded the casing with water to give them added weight. The last 10 feet of casing needed washed down into place, so 475 barrels of fresh water were pumped down the casing, in an attempt to set it into place. They were unable to successfully land the casing, so it was decided to pull the casing out of the hole and run back in with a tricone bit to drill out the hole.
1525128355 2018-04-30 Casing String Witnessed No Violations On this day, I am here to witness the 18.625-inch diameter surface casing mine-string cement job with Halliburton Energy Services. The Patterson 803 rig drilled a 24-inch diameter borehole to a depth of 991 feet from a Kelly Bushing of 28 feet. The coal seam was encountered from a depth of 844 feet to 856 feet, without a void. Then, Mikes Power Tong Services inserted 904 feet of 18.625-inch diameter J-55 87.5 lb./ft. casing into the borehole. The landing joint was damaged, so a new one was brought in to replace it. The last 10 feet of the landing joint needed washed down. The DV (differential valve) tool is set at a depth of 624.7 feet and the packer is set at 627.5 feet. Halliburton held a pre-job safety meeting. They pumped 100 barrels of fresh water spacer, 25 barrels of gel spacer, and 10 barrels of fresh water spacer ahead of the cement. Then, they cemented the casing with a two-stage cement job. The first stage is pumped with 28 barrels total volume of 130 sacks of Class A cement with a 1.227 yield and a weight of 15.8 pounds per gallon. It was displaced with 276 barrels of fresh water. The plug landed with 120 psi. The first stage of cement is in place and the packer is set. After the packer was set, the pressure test for the casing and the packer were being conducted, and there became a sharp spike in the pressure. The cement head and crossover joint were ejected from the top of the landing joint. It was being held down by four chains and attached to a winch line. Two of the four chains broke, and the winch line caught the cement head in mid-air, from falling to the ground. At the time of the incident, no one was on the rig floor, and there were no injuries. The casing did not move and did not appear to be damaged The cross-over joint became bent after the cement head landed, but Halliburton indicated that the cement head is fine and they will replace the cross-over with a new one. The landing joint will also be replaced, as well as the chains, including the
1652713634 2019-04-08 Production Wells No Violations On this day, I am accompanying ODNR Engineers Mark Atkinson and Andy Thomas, ODNR Southeast Supervisors Brent Bear and Mike Moreland, and CNX Gas Representatives John Hardcastle, Rick Harless, and others. The meeting is to review the new proposed well locations. The existing production wells were also inspected. The 9.625 inch diameter intermediate casing has a pressure of 140 pounds per square inch (PSI), and the 13.375 inch diameter surface casing has a pressure of 950 PSI. On 4/8/2019 I left a message with John Zachwieja, CNX Production Foreman, to notify him of the pressures.
