0050341569 2018-01-18 Completion Testing No Violations Status check inspection on the well completion process found Deep Well tubing snubbing unit # 9 on location. The unit has drilled out the completion plugs and pulled the workover string and is running in the hole with the 2.875 production string to be set at a depth of 11,140. The well is being controlled using a balance method with brine water in the well bore. Tetra Technologies flow back service is on location and rigged up as the flow back service. The well bore fluid is being circulated into a total of (30 steel construction open top 500 barrel capacity tanks. The well head assembly is made up of a Cameron Lower and B section and tubing cross section. The service unit and equipment is placed on polymer containment with the well pad perimeter berm serving as the primary containment.
1007973188 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 (3) producing wells, (3) gas processing units (GPU), (3) 400-barrel and (1) 50-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 950 pounds per square inch (psi), and the 13.375 inch diameter surface casing has a pressure of 460 psi.

1498670164 2017-06-28 Drill / Deepen / Reopen No Violations The purpose of my inspection was a status check on drilling operations. During my inspection Patterson Rig 803 had reached total depth at 20244 feet and had 5.5 inch diameter production casing set at 20163 feet. Prior to my arrival BJ Service had just completed the cementing of the 5.5 inch diameter casing. I obtained the post cement job report and discussed with the CNX company man their timeline for walking, spudding, and cementing surface/mine string casing on the Switz 7 D well. The rough estimate for cementing the surface/mine string is Thursday night. The coal seam will be at 595 feet to 604 feet.
1517770241 2018-02-04 Completion Testing No Violations On this day I received a call at 10:59 am from ODNR Emergency Response member Nathan Lane who indicated the company had reported a fluid release on site from the completion flair stack. I arrived on site at 11:10 am and contacted the Company man on site who indicated they had recovered any material affected from the release. It was observed that a area directly below the TETRA Company flair stack well control device had been excavated and loaded into a roll off container with what appeared to be approximately 1.5 yards of mostly limestone gravel inside the container. There was a polymer liner in the container however no standing fluid or sheen could bee seen inside the container. The area of excavation was also checked and no standing fluid or sheen could be seen. There was a well pad perimeter drain on site near the release and was in the closed position. Addressing the well status, the well drilling and stimulation process is complete. The completion plugs have been drilled out and production tubing hung in the well. TETRA flow back services are on site and rigged up to the said well, they will begin the initial well bore production flow back on this day.
2058318159 2017-05-25 Casing String Witnessed No Violations On site inspection to witness the conductor casing cement job with Express Energys top hole rig and cement service. The auger rig has drilled a 36 diameter borehole to a measured depth of 100 and inserted 100 of 30 diameter .375 wall 118 pound per foot conductor. Express then cemented the casing with a 48.9 barrel cement mix consisting of 275 sacks of class A cement with the cement weight verified by weight of scale at 15.6 pounds per gallon. Cement returns were witnessed to surface inside the cellar at 58 barrels into a total of 75 barrels of fresh water dissplaceent.1 of cement was left in the cellar causing a liquid tight seal. No fresh water was encountered in the borehole while drilling.
