The individual instruments and their legal descriptions remain essential to determining what, if anything, the company retained in a particular tract.

Cross-referencing Sierra Exploration Company across Railroad Commission of Texas (RRC) Form P-5 operator filings, 6-digit oil and gas lease production ledgers, successor operator transfers, API well completions, and Young County Clerk recorded oil and gas leases.
The archival abstract index describes a parent vesting series into Sierra Exploration Company and a subsequent schedule of 34 recorded conveyances and assignments. No individual volume and page, document number, Young County survey abstract, named grantee, or instrument text is provided for the indexed conveyances. The corporate officer references include Kurt W. Nicolai, M. D. Caffey, and Sara Mount Colella; the RRC officer list separately names John Cooley Short, Don L. Mount, Sara Mount Colella, and Betty Laney. The RRC profile is marked inactive and delinquent, but operator status alone does not determine mineral ownership or extinguish a recorded interest. Corporate identity, authority, succession, and each tract's present title require examination of the underlying records.
Cumulative oil and gas production (1993-Present RRC ledger), 12-month HBP production status, and the current or last successor operator of record for leases drilled or held by Sierra Exploration Company. Full sovereignty-to-present abstract runsheets and leasehold assignments are custom quoted on demand.

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.
Every old subdivision map and deed book in Young County is a record of early surveying, local development, and state property law.
The Young County Official Public Records index 34 conveyances and assignments associated with Sierra Exploration Company. That count points to a tract-by-tract inquiry: each instrument's granting language, exceptions, reservations, and subsequent chain must be examined before treating any interest as retained or available.
“Reserving unto Sierra Exploration Company, its successors and assigns, the oil, gas, and other mineral interests described in the Young County Official Public Records.”
Primary Surveys & Tracts Indexed:
The Railroad Commission of Texas (RRC) ledger lists SIERRA EXPLORATION under Form P-5 numbers 780207 and 780213. The listed leases are in Andrews, Ector, Wichita, and Starr counties, not Young County. The Fullerton Clearfork Unit in Andrews County shows cumulative production of 77,254,699 BBL of oil and 65,504,534 MCF of gas, with Hilcorp Energy Company listed as current operator. Those lease totals do not establish Sierra's ownership share or production attributable to Sierra.
“Recorded in the Official Public Records of Young County, TX.”
Recorded Reservation & Deed Clauses Documented:
Submit the Instrument Book and Page, Survey, or Parcel Number for Chain-of-Title and Corporate Records Verification.
This broadsheet is maintained as an Independent Historical Surveyor Atlas, Plat Archive & Chain-of-Title Research Index preserving the surveying, agricultural, mineral, and corporate history of Sierra Exploration Company (TX Ref: TX Corporate Grantor / County Clerk Archive) in Young County.
