2353801 Primary Facility 2015-03-19 Routine/Complete Inspection No Violations Noted Arrived on 3/19/15 @ 9:30, cold, windy, sunny. With me were OGIs Ken Kennedy, Joe Gaboff, and David Schoonover. There are 6 wells on the pad. The 1H was previously drilled and had been in production for some time. The 2H-6H were drilled to TD during 12/14. 2H, 9-5/8” x 5-1/2” - 35% methane, measureable flow, 6H: 9-5/8” x 5-1/2” - 21% methane, cement tops are down. Other annuli: 0 at the time of this inspeciton. The liner was still in place on the messy location.
2363814 Primary Facility 2015-04-01 Follow-up Inspection No Violations Noted 115-hr shut-in pressure test.
2378132 Primary Facility 2015-06-09 Follow-up Inspection No Violations Noted Arrived @ 11:00. Weather: thunder storms last night and today. Met with Chief’s Jon Hafer to begin 72-hour pressure build-up test. Heavy rain made setting up a challenge. Continuous pressure loggers were installed on the 13-3/8” x 9-5/8” and 9-5/8” x 5-1/2” annular vents for the 2H, 3H, 4H, 5H, and 6H wells. The loggers were set to begin taking readings at 13:00. To ensure that pressures did not exceed regulatory limits, Hafer planned to visit the location each day. The 1H, drilled previously was in production.
2379022 Primary Facility 2015-06-09 Follow-up Inspection No Violations Noted Arrived @ 11:00. Weather: thunder storms last night and today. Met Jon Hafer to begin 72-hour pressure build-up test for the G&S Big Rigger 2H, 3H, 4H, 5H, and 6H wells. Annuli were open with vents plumbed to polytanks prior to the start of the test. Gas was detected at the polytank for the 2H and 4 H wells, and the tank for the 6H (4% methane). Gas was not detected at the tank for the 3H and 5H at the time of my inspection. On the 6H, the annular vent pipe configuration required some modification prior to shut-in. Hafer plans to check daily to ensure pressure on the 6H 13-3/8” x 9-5/8” does not exceed regulatory limits. The 1H, in production, appeared to be discharging more fluid and gas than seen on previous inspections from its annular vents to its polytank (5% methane detected at polytank). There were not enough pressure loggers to include the 1H in this pressure build up test.
2379218 Primary Facility 2015-05-29 Follow-up Inspection No Violations Noted Arrived @ 10:00. Weather: sunny, hot and breezy. Already onsite was DEP OGI Ken Kennedy, Team rig crew and Baker Hughes crew. Met with company man Floyd Roberts. Freepoint on 6H determined to be 1550’, approximately 40’ below the intermediate casing shoe. Discussed pros and cons of conducting planned remediation at this depth. At approximately 15:00, Chief decided to cancel proposed remediation. Staff begain preparations to rig down and travel to Woodlands Unit A location to drill out plugs. Left location at approximately 15:30.
2379248 Primary Facility 2015-06-10 Follow-up Inspection No Violations Noted : Arrived @ 15:00. Weather hot and humid. Annuli on G&S Big Rigger 2H, 3H, 4H, 5H, 6H shut-in for pressure build-up test. Purpose of inspection to check pressure build up on 6H annuli. After 26 hours 9-5/8” x 5-1/2” annulus at 132.85 psig. 13-3/8” x 9-5/8”, slight pressure build. Left @15:45.
2379331 Primary Facility 2015-06-15 Follow-up Inspection No Violations Noted Arrived @ 10:45. Cloudy, hot, humid, sticky with occasional cloud bursts. Met with Jon Hafer and DEP Mineral Resource Program Specialist Rick Swank to try to conduct annular flow measurements. 9-5/8” x 5-1/2” annulus on 6H measured 0.09 inches of water using the 1/8” orifice plate. This measurement was consistent on both Hafer’s and Swank’s digital meters. The DEP analogue meter which measures 0-10 inches of water was not sufficiently sensitive to measure this flow. At the conclusion of the pressure build up test for the 6H, leaks in some of the well head seals were discovered. As a result Chief intends to do another pressure build up test for the 6H. Left location at 12:46.

2428009 Primary Facility 2015-11-24 Routine/Complete Inspection Outstanding Violations - No Viols Req'd Arrived 11:30, cloudy and cold. There are 6 wells on the location. The G&S Big Rigger 1H is in production. The other wells have been TD’ed but not hydraulically stimulated. There is liner on the pad location.
2480038 Primary Facility 2016-04-27 Drilling/Alteration Outstanding Violations - No Viols Req'd Arrived @ 9:45. Weather: sunny. Met with Jon Hafer (Chief). The purpose of this inspection was to observe the shut-in flow rate testing being conducted on the 6 G&S Big Rigger wells. At the time of my inspection the shut-in test on the G&S Big Rigger 3H was being concluded. The shut-in well was fitted with continuous pressure loggers and remote read transducers. At the conclusion of the test, these devices were transferred to the G&S Big Rigger 1H. The annular vents were shut but the well remained in production.

G&S Big Rigger 3H: 13-3/8” x 9-5/8” and 9-5/8” x 5-1/2” annular vents were shut in from 04/20/16 @ 15:05 to 04/27/16 @ 09:20. Neither of the annuli built sustained pressure during the test.

2493864 Primary Facility 2016-06-06 Routine/Complete Inspection Outstanding Violations - No Viols Req'd
2499388 Primary Facility 2016-06-30 Routine/Complete Inspection Outstanding Violations - No Viols Req'd Arrived @ 13:30. Weather: sunny, low humidity, warm. Met with Jon Hafer and Floyd Roberts (Chief). The purpose of this inspection was to check on progress with frac monitoring and long-term annular pressure monitoring. The G&S Big Rigger 2H-6H wells were being prepared for toe prep. At the time of my inspection staffers were waiting for a replacement seal assembly for the 6H because one of the seals was split. The seal was examined because pressure on the 6H’s 5-1/2” casing was encountered when the blind flange was removed. B-sections on several well heads had also been replaced due to seat ring pitting which was observed after the blind flanges were removed. These activities compromised the conclusion of the long-term annular pressure monitoring project.

2508097 Primary Facility 2016-08-05 Routine/Complete Inspection No Violations Noted
2509307 Primary Facility 2016-08-09 Routine/Complete Inspection No Violations Noted Routine inspection to assess hydraulic fracturing operations. Jon Hafer of Chief was present during the inspection.

All equiment and amterials on site were within containment. No evidence of spills was observed during the inspection. Three barrels marked "waste fuel" and several other containers were observed within a small secondary containment not appropriately sized to contain the volume of the barrels and containers. Though the barrels were empty at the time, it was advised that they should be placed in containment that would adequately hold the volume of fluid that could potentially be placed in the barrells.

During the inspection a seal on piping connecting to one of the wells failed. At the time, the well was not pressurized and only a minimal amount of fluid was released to the containment surrounding the well head. No fluid left containment. Repairs on the seal commmenced immediately.

No violations were cited during this inspection.

2514663 Primary Facility 2016-08-16 Drilling/Alteration Outstanding Violations - No Viols Req'd Arrived @ 10:55. Weather: hot, humid, with rain and threat of rain. Hydraulic fracturing operations were ongoing at the time of my inspection. Universal was handling the frac with Cased Hole Solutions handling the wire line. The purpose of my inspection was to check on the frac and document arrangements for monitoring annular pressures on wells that were not being pumped. I met with company man Brett Fowler (Chief). He reported that the zipper frac involving the three wells with northwest trending laterals: G&S Big Rigger 4H, 5H, and 6H, was at approximately stage 20-21 out of 27 stages on each of the wells and was scheduled to be finished tomorrow. The 2 wells with southeast-trending laterals: G&S Big Rigger 2H, and 3H, would be fracced next. During these operations the G&S Big Rigger 1H, a producing well, was shut-in.
2514870 Primary Facility 2016-08-24 Drilling/Alteration Outstanding Violations - No Viols Req'd Arrived @ 13:54. Weather: hot. Hydraulic fracturing operations were ongoing at the time of my inspection. Universal was handling the frac with Cased Hole Solutions handling the wire line. The purpose of my inspection was to check on the frac and follow-up on Chief’s 08/23/16 report of a possible communication between the frac on the G&S Big Rigger 3H and Chief’s Dacheux 3H, a producing well whose lateral was located approximately 9,300’ away from the G&S Big Rigger 3H lateral. I met with company man Brett Fowler (Chief), who said he knew nothing about the possible communication and wanted me to talk to his boss, Ted Balch (Chief Completions Superintendent). Following the phone calls I asked Mr. Fowler about the on-going operations. He told me that, at the time of my inspection they were approximately 1 hour into fraccing stage 21 stage of the G&S Big Rigger 3H, and finishing the stage would require approximately another hour. There would be a total of 29 stages. Afterward they would frac stage 21 of the G&S
2517128 Primary Facility 2016-09-07 Routine/Complete Inspection No Violations Noted
2518945 Primary Facility 2016-09-14 Routine/Complete Inspection No Violations Noted Routine site inspection to assess overall site conditions post-completion of wells. All equipment and tanks on site were within containment. Fluid in the containment surrounding the brine tanks being used for flowback was screened for electrical conductivity and registered 8.0 mS/cm using a Oakton handheld meter.

Several puddles were present along the east edge of the well pad. The electrical conductivity of these puddles was also screened, and yeiled results of 2.4 and 3.4 mS/cm. A sample of the puddle with the 3.4 mS/cm electrical conductivity was collected for laboratory analysis. No obvious staining was observed on the pad surface that could indicate a spill. No stressed or dead vegetation was observed in the areas surrounding the well site.

No violations were cited during this inspection.

2535222 Primary Facility 2016-10-27 Follow-up Inspection No Violations Noted Follow-up inspection conducted after receiving laboratory analysis of fluid samples collected during last inspection (Inspection ID No. 2518947, September 14, 2016). No Chief representatives were present during the inspection.

During the September 14, 2016 inspection, fluid samples were collected from a puddle on the well pad in response to field electrical conductivity readings of 3.4 mS/cm. The puddle was located along the east edge of the well pad. No sheen was present on the puddle, and no staining or odors were observed. Chief was notified of these findings, and had all puddles on the pad vacuumed and removed.

The laboratory analysis (SAC 942) indicates elevated levels of chlorides (1,713.1 mg/L), strontium (25,830 ug/L), iron (1,130 mg/L), total dissolved solids (3,050 mg/L), and manganese (22.55 mg/L). Elevated levels of these constituents indicate that a release of produced water or flowback occurred on the well site.

Electrical conductivity was screened in the same area where the elevated re
