To protect landowner privacy and chain-of-title integrity, individual Net Revenue Interest (NRI) decimals, living heirship trees, unredacted lease expiration schedules, and complete sovereignty-to-present abstract runsheets are withheld from public display and quoted on demand based on page volume, instrument count, and unit value.

Five Wells, One Reported Production Total

The Railroad Commission of Texas (RRC) ledger identifies five Red Oak (Woodbine Dexter) Unit wells in A-102, including API 42-289-31451 and API 42-289-31372. Each entry repeats cumulative production of 1,598,130 BBL of oil and 78,830 MCF of gas for RRC lease 05-03966, so those figures should be counted once, not five times. The entries identify Rusk Energy Operating LLC, P-5 735144, as current operator and report production through October 2026. Production in the abstract alone does not establish that a South Dakota Texas Oil Co interest is included in the unit or held by production.

The contract for deed at Doc/Vol 37/251 is an entry point, not proof of a surviving reservation. Each instrument's granting and reservation language, legal description and subsequent chain must be examined before assigning an interest to the company or its successors.
