The Sand Hills Field in western Crane County, Texas — named for the wind-blown dunes that cover it — is a multi-reservoir giant that has produced since 1930 from stacked Permian carbonates, principally the Tubb and McKnight zones, with deeper Ordovician production beneath. Developed largely by Gulf Oil across a sweep of ranchland southwest of the town of Crane, the field grew into a complex of separately regulated reservoirs and waterflood units whose combined recovery ranks it among the Central Basin Platform’s major accumulations. For mineral owners, Sand Hills means multiple pays and a very long production tail.

Sand Hills was opened in 1930 as the drilling boom that began with Church & Fields and McElroy spread west across Crane County. Early completions found oil in shallow Permian carbonates, and the field was progressively delineated through the 1930s into distinct producing zones — the Tubb and McKnight chief among them — each treated as its own reservoir under Texas regulation. Gulf Oil assembled the dominant lease position and made Sand Hills one of the anchors of its West Texas empire.
Deeper drilling in later decades added Ordovician production beneath the Permian section, extending the field’s stacked-pay character. As the primary era waned, the major zones were organized into waterflood units in the post-war period, and injection became the mainstay of recovery across the Tubb and McKnight reservoirs. Academic and industry studies of Tubb and lower Clear Fork deposition at Sand Hills documented the layered, heterogeneous carbonates that made careful flood management essential.
Gulf’s position passed to Chevron in the 1984 merger, folding Sand Hills into the same legacy portfolio as the other Crane County giants, and the field’s mature units have continued under long-tail management ever since, with consolidation toward operators focused on late-life conventional assets. More than ninety years after discovery, Sand Hills remains a producing complex rather than a historical footnote — the normal fate of big, flooded carbonate fields on the platform.
Sand Hills produces from a stacked Permian section on the southwestern Central Basin Platform — most importantly the Tubb and McKnight carbonate intervals of the Clear Fork group — with deeper pays extending into the Ordovician. These are layered, dolomitized shelf carbonates: thick oil columns distributed through alternating porous and tight beds that hold large volumes in place but resist efficient drainage. That architecture is why the field supported decades of pattern waterflooding, and why multiple separately produced reservoirs can underlie a single mineral tract.
Recovery at Sand Hills has been dominated by long-running waterfloods across its principal Permian reservoirs, initiated in the post-war unitization era and sustained for decades since. Multi-zone fields like this age gracefully: when one reservoir’s flood matures, recompletions and infill programs in adjacent zones keep wellbores and units economic. The field also sits within the Permian’s established CO2 and residual-oil-zone fairway, where operators continue to evaluate legacy carbonates for incremental recovery. For royalty owners, the through-line is durability — production measured in generations, not drilling cycles.
Minerals under Sand Hills carry the compounding advantages of stacked pay, unitized flood support, and nine decades of operating history. They also carry complexity: one tract may participate in several units across different zones, each with its own decimal and payout behavior, and that complexity is where uninformed sales lose value.

County-level well data, production charts, and selling guides for the counties this field spans:
Yes. Sand Hills has produced continuously since 1930, with waterflooded Tubb and McKnight units and deeper zones still active across the field’s large footprint in western Crane County.
Gulf Oil built the dominant position and developed the field for half a century; Chevron inherited it in the 1984 Gulf merger, and mature units have since consolidated toward late-life conventional specialists. Your division orders identify current unit operators.
Each producing unit and zone contributes its own income stream, so a fair valuation aggregates every decimal you hold rather than pricing one check. We evaluate multi-unit interests directly and provide free written offers showing the full picture.
