Baxterville, discovered by Gulf Oil in 1944 on the border of Lamar and Marion counties, ranks as Mississippi’s largest oil field by cumulative production, with more than 250 million barrels of oil and roughly 500 billion cubic feet of gas recovered. The field covers about twelve and a half square miles in the southwestern part of the state and has produced from Tuscaloosa sandstone along with Selma and other Cretaceous intervals. It is a mature, water-handling-intensive field today, with royalty ownership divided among many small interests across two counties.
Gulf Oil made the Baxterville discovery in 1944, with oil development following through 1945 along the Lamar-Marion county line. It arrived during the wartime expansion of Mississippi drilling that followed Tinsley and Heidelberg, and it quickly outgrew both in cumulative terms. For years afterward Baxterville ranked as the state’s highest oil producer. Leasing across pine and farm country created a fine-grained pattern of mineral tracts, and the reservations from that decade are the origin of most of the small undivided interests recorded in the two counties today.
Production came from a layered Cretaceous section, with Tuscaloosa sandstone the principal contributor and Selma and other intervals adding volume. The field is comparatively compact — roughly twelve and a half square miles — but was drilled and produced intensively for decades. Cumulative recovery moved past 250 million barrels of oil and around 500 billion cubic feet of gas, a total no other Mississippi field has matched, and the accompanying produced-water volumes were enormous by any standard.
Water is the defining operational fact of Baxterville’s later life. More than a billion barrels of brine have been produced and disposed of since 1944, and the United States Geological Survey studied brine effects on groundwater and streams in the field area. That history shapes modern economics: lifting, separating and disposing of very large water volumes is the main cost of keeping the field alive. Operatorship has passed to independents who specialize in mature Mississippi production.
Baxterville produces from the Upper Cretaceous section of the Mississippi Salt Basin, with the Tuscaloosa sandstone as the principal reservoir and Selma and other intervals contributing. The trap is associated with salt-related structure typical of the basin, where movement of deep Louann salt created closures and faulting. The field footprint is small — about twelve and a half square miles — but the productive section is thick and layered, which is how a compact field accumulated more oil than any other in the state. Reservoir quality varies vertically more than laterally here.
Baxterville has been produced with pressure maintenance and waterflooding, and the sheer volume of water involved is the field’s signature. More than a billion barrels of brine have been produced and reinjected or disposed of since 1944, a figure that underscores how thoroughly the reservoirs have been swept. For owners, water handling is the practical constraint on field life: when the cost of lifting and disposing of water exceeds the value of the oil it carries, wells are shut in. Unlike Tinsley and Heidelberg, Baxterville is not a Mississippi CO2 flood.
Lamar and Marion county interests in Baxterville are typically small fractions attached to a field that has already given up most of its recoverable oil, with economics governed by water handling. That is a specific valuation problem, not a generic one, and it is easy to get wrong in either direction using a simple multiple. We look at the lease, the producing interval and the operator’s cost structure before quoting. Pointer Minerals buys direct: we buy minerals and royalties in Lamar and Marion counties and provide free written offers.
County-level well data, production charts, and selling guides for the counties this field spans:
Because it sets the economic floor. Wells here lift enormous volumes of brine for each barrel of oil, and separating and disposing of that water costs real money. When those costs approach the value of the oil, operators shut wells in. Water cut and disposal capacity are therefore central to how long your interest keeps paying, and we factor them into any offer.
Baxterville has been a waterflood field, unlike Tinsley and Heidelberg, which are anchor properties of the Jackson Dome CO2 system. Operators evaluate candidates over time and plans can change, so we verify current recovery method from state records for the specific lease rather than assuming. We will tell you plainly what we find.
The tracts in each county are described and conveyed separately and the deed is recorded in both counties. Title must be clear in each. This is routine for a field that sits on a county line, and we prepare the recording package for both counties as part of closing so you are not left coordinating it yourself.
