The riser pipes are also tied into a steel line that runs to the production tanks at the production facility, there are a total of 6 tanks present that are steel construction and capable of holding 400 barrel of fluid each.. The riser pipes are equipped with valves that are in the open position. There is also a total of (2) streel riser pipes present that are cementing into the annular spaces between the conductor and surface casing strings and the surface and first intermediate casing strings. These 2 pipes are 1 in diameter and have ball valves attached to he end of the pipes, the ball valves are in the open position. The well head is equipped with a tubing head section and the production lines are in the closed position.

2005557460 2018-03-22 Production Wells No Violations Inspection report to document the well head annular pressures as a follow up to a well control incident that occurred on the well pad on 02/15/2018 involving the Schnegg #7 well. The 9.625 casing head which is the pressure between the 5.5 casing outside diameter and the 9.625 casing inside diameter had a recorded pressure of 2,156 pounds per square inch. The 13.375well head section which is the pressure between the 9.625 casing outside diameter and the 13.375 casing inside diameter had a recorded pressure of 50 pounds per square inch. Both records are recorded data from the Companys electronic recording system (SCADA).
