Hobbs Field is the discovery that made southeastern New Mexico an oil province. On June 13, 1928, the Midwest State No. 1 found oil at 4,065 feet in Lea County, and the small farming settlement of Hobbs became a boomtown almost overnight. Production came from Grayburg and San Andres dolomite, with deeper Permian pays developed later, and the field went on to yield hundreds of millions of barrels. Waterflooding extended its life well beyond primary depletion, and the Hobbs area has remained a working oil district for close to a century.
New Mexico had produced small volumes of oil since the early 1920s, but nothing on a commercial scale in Lea County until the Midwest Refining Company spudded the Midwest State No. 1 in October 1927 with a cable-tool rig. Oil came in on June 13, 1928 at 4,065 feet. The well was modest by later standards, yet it proved a major Permian accumulation beneath ranch country, and it triggered the state’s first genuine oil boom. Leasing and drilling swept across Lea County within months, and the community of Hobbs grew from a crossroads into a city.
Development through the 1930s and 1940s defined the field’s shape: a broad producing area on the Central Basin Platform, with the shallow Grayburg and San Andres carbonates carrying most of the early volume and deeper horizons added as operators drilled below the original pay. The field supported gas plants, refineries, and a service economy that made Hobbs the commercial center of southeastern New Mexico. Statewide conservation rules arrived with the New Mexico Oil Conservation Commission, and spacing, allowables, and pool designations began shaping how the field was produced.
By mid-century, primary drive was fading and secondary recovery took over. Leases were pooled into units and converted to water injection, restoring pressure and recovering oil that would otherwise have stayed in place — the same arc followed by Vacuum, Eunice-Monument, and the rest of the Permian shelf giants. Hobbs has since passed through many rounds of ownership and, more recently, sits within a county transformed again by horizontal drilling in the Delaware Basin. The legacy shallow pools continue producing alongside that newer activity.
The Hobbs accumulation lies on the Central Basin Platform, where Permian shelf carbonates — principally the Grayburg and San Andres — form porous dolomite reservoirs at roughly four thousand feet and below. Structure and stratigraphy work together here: gentle closure combined with facies changes traps oil in porous zones sealed by tighter carbonate and evaporite above. Deeper Permian intervals contain additional pays that were developed after the original discovery. Because porosity is diagenetic and unevenly distributed, well results have always varied over short distances, which is why the field is developed through engineered patterns rather than uniform spacing.
Like its neighbors, Hobbs moved from solution-gas drive to waterflooding as the way to keep producing. Unitized water injection restored reservoir pressure and swept oil toward producers, adding decades of life to pools that had already been drilled for a generation. The economics of that work — injection, workovers, artificial lift, and water handling — govern how long each area keeps producing. In parts of Lea County, horizontal development of deeper unconventional targets now overlaps the historic field area, so a single tract can carry both legacy shallow production and newer activity.
Hobbs interests are often old family holdings, sometimes fractionated across several generations and several pools. That complexity is where value gets lost: an owner may not realize the same acreage carries both a legacy waterflood interest and exposure to deeper horizontal development. New Mexico’s Oil Conservation Division reports by pool, so your paperwork may look unfamiliar even when the tract is well known. We buy minerals and royalties in Lea County and provide free written offers that spell out what we identified in your acreage.

Small legacy interests in Lea County are frequently worth more than owners expect, particularly where deeper horizontal development has reached the same acreage. The only way to know is to look at the tract, the pools it produces from, and any recent permits. We do that review at no cost and put the result in writing.
Because New Mexico assigns production to pools, and one tract can lie above more than one producing horizon. A shallow Grayburg or San Andres pool and a deeper Permian pool may both be credited to your acreage, each with its own decimal. It is common and it is not an error, but it does mean a proper valuation has to account for each stream.
They are different assets. Selling royalties transfers a share of revenue from existing production; selling minerals transfers the executive right to lease future development as well. Many owners sell one and keep the other. We will price either and explain the difference in plain language before you decide anything.
