RP72-6, et al., and CP79-224. Unless otherwise stated, all volumes are reported using a pressure base of 14.73 psia and a temperature base of 60 F. All volumes are listed in Mcf, unless otherwise stated. The storage activity cycle covered in this report is from November 1, 2017 through April 30, 2018. 1) The daily volume of natural gas injected into and withdrawn from the storage facility. Attached as Exhibit 1 is the list of daily injection and withdrawal volumes for Washington Ranch for the November 1, 2017 through April 30, 2018 reporting period. 2) The volume of natural gas in the storage facility at the end of the reporting period. The volume of gas in the reservoir as of May 1, 2018 was 37,616,937 Mcf at 14.73 psia. 3) The maximum daily injection or withdrawal rate experienced during the activity period, and the average working pressure on such maximum days, taken at a central measuring point where the total volume injected or withdrawn is measured. Working Telemetered Data Volume (MMcf) Pressure (psia) Maximum Injection: 134.2 661.5 Maximum Withdrawal: 223.6 618.1 4) Results of any tracer program by which the leakage of injected gas may be determined. If leakage of gas exists, the report should show the estimated total volume of gas leakage, the volume of recycled gas and the estimated remaining inventory of gas in the reservoir at the end of the reporting period.

Docket Nos. RP72-6, et al., CP79-224, and CP15-516 EL PASO NATURAL GAS COMPANY, L.L.C. SEMI-ANNUAL ACTIVITY REPORT WASHINGTON RANCH STORAGE FACILITY For the Period: November 1, 2017 April 30, 2018 There was no indication of any gas leakage from the field/reservoir during the November 1, 2017 through April 30, 2018 reporting period. 5) Any surveys of pressures in gas wells, and the results of back-pressure tests conducted during the reporting period. No bottom-hole pressure survey was conducted during the November 1, 2017 through April 30, 2018 reporting period. Further, there were no water levels detected in observation wells. During the November 1, 2017 through April 30, 2018 reporting period, a shut-in pressure survey was conducted on April 6, 2018. Recorded pressures are attached in Exhibit 2. No back-pressure tests were conducted during the November 1, 2017 through April 30, 2018 reporting period. As the gas storage reservoir in Washington Ranch Field is not an aquifer-type reservoir, no pump-tests were performed. 6) The latest revised structure and isopachous contour maps showing the location of the wells, the location and extent of the gas bubble in the storage reservoir for aquifer-type reservoirs and in any other reservoirs of the project in which gas bubbles are known to exist, and the location of the gas-water contact if one exists. This map need not be filed if there is no material change from the map previously filed. No revisions have occurred to the structure or isopachous contour maps during the November 1, 2017 through April 30, 2018 reporting period. The location and extent of the gas bubble is not applicable for the type of reservoir which exists in the Washington Ranch Gas Storage Field. 7) For the reporting period, a summary of wells drilled, recompleted or worked-over, with subsea depth of formation and casing settings. No drilling, re-completion, or work-over activity occurred during the November 1, 2017 through April 30, 2018 reporting period. Washington Ranch Semi-Annual Storage Report Page 2 of 3
