The wells <br />will all be buried at the same time when the well pads undergo reclamation work <br />in spring or summer of 2024. <br />• During July and August 2023 NS built a new 3 acre well pad “18H-1V” near the <br />southern portion of the lease where the proposed 18H, 19H, and 20H-1V slant <br />production wells will be drilled and completed. The dirt work and gravel <br />operations were completed by Moody Services. <br />• A new 1,600 foot 18H-1V access road was built by Moody services in July and <br />August 2023 to connect the new 18H-1V location to an existing access road to <br />the north of the pad. <br />• A new pipeline was constructed in fall of 2023 on the 18H-1V access road that <br />will connect the existing pipeline infrastructure to the new feed from the <br />proposed 18H/19H/20H-1V wells. <br />• A 2 acre southern extension of the existing 15H-17H West location was built <br />and graveled in July and August 2023. The proposed 18H-IR-W and 19H-IR-W <br />production wells will be drilled and completed on this location. <br />• NS conducted discrete zone water sampling of the DS-3, DS-6, DS-7 and DS- <br />10 wells for annual water quality analysis on June 20, 2023. <br />• P&A operations occurred on the 17H-I production well between August 7 <br />through the August 11, 2023.
