Inspection Data

Inspections Performed

Inspection ID Inspection Date Inspection Type Inspection Result Inspection Comments
-852310169 2020-5-18 0:00: PL No Violations 1.00
0096616034 2018-02-21 Production Wells No Violations Status check inspection found the well drilling and completion process now complete and the well in line and producing from the tubing flow cross section. The casing section of the well head is isolated with no flow lines attached. All well head annulis have pressure gauges and flow lines present with check valves present on the flow lines. On location is also a production fluid tank battery consisting of a total of (4) tanks of steel construction design situated inside a polymer lined steel containment area. Also on location is 4 gas processing units on each servicing each well on the pad. EQT also has a midstream operation off the back corner of the well pad. Emergency Shut down devices are located at the well pad entrance-at each well head -the tank battery and the gas processing units.
0313813059 2017-08-03 Completion Testing No Violations The purpose of my inspection was a status check. During my inspection the well was equipped with a frac valve in the closed position. The pad surface was lined with containment liner and frac tanks were being placed on containment. Location was in preparation for hydraulic stimulation operations.
1333809978 2018-05-21 Production Wells No Violations Producing well status check found that a total of 4 wells are present on the well pad and in production with the production valves on the tubing head assemblies in the open position. There is a total od 4 gas processing units on location and 4 steel design production tanks. A 3rd party midstream operator identified as EQT is set up at the rear of the well pad. There is a large portable water storage tank used in the stimulation process set up on the well pad also.
1489584299 2017-03-14 Drill / Deepen / Reopen No Violations During my inspection Patterson Drilling Rig 803 was rigging up on location. I spoke with the CNX Company Man and he stated that the estimated day to spud the surface borehole will be Thursday 3/16/17.
1490010766 2017-03-19 Casing String Witnessed No Violations The purpose of my inspection was to witness the surface-mine string cement job. The coal seam is from 623 feet to 635 feet in depth. Patterson Drilling Rig 803 drilled a 24 inch diameter borehole to a depth of 704 feet. The 18.625 inch diameter casing, 87.5 pounds per foot, was run to a depth of 676 feet. Allied Cement Services was on location to cement the casing string in two stages with a packer set at 402 feet. 180 barrels of fresh water, 26 barrels of gel, and 5 barrels of fresh water were pumped ahead of the cement. 59 barrels of Class A cement with 1.5 percent calcium and 207 barrels of displacement were pumped to complete the first stage. The plug landed and the packer was energized. The second stage was completed using 44 barrels of fresh water, 25 barrels of gel, 5 barrels of fresh water, and 168 barrels of Class A cement with 1.5 percent calcium. 122 barrels of displacement were pumped, the floats held, and 27 barrels of cement returns were witnessed in the cellar. Cement density from both stages was checked during the job using pressurized scales confirming the weight of 15.6 pounds per gallon.
1585319135 2017-08-16 Completion Testing No Violations The pad is named Switz 26 and consists of 4 wells. During my inspection Universal Pressure Pumping, Allied Wireline, and CNX Company Man were on location. Universal Pressure Pumping was rigged up for hydraulic stimulation operations on the C and A well. Operations were at a stand-still and there was not any equipment in operation. I discussed with CNX Company Man annular pressure monitoring. He stated that they monitor the annular pressure at the wellhead and then run a line to the frac van when operations begin to record and monitor their pressures. The wellhead was equipped with a frac stack and goat head assembly with all valves in the close position. Annular pressure monitoring was present. A 2 inch diameter steel line was plumbed up to the 9.625 inch diameter casing and ran to a bled off tank.
1608610623 2017-03-17 Drill / Deepen / Reopen No Violations During my inspection Patterson Drilling Rig 803 was in the process of rigging up. I spoke to the company man on location and he stated the he will notify me when they spud and he expects it to be some time tonight.
