What Longfellow Energy does

Longfellow Energy, LP is a privately held oil and natural gas exploration and production company founded in 2006 by Malone Mitchell, 3rd and headquartered in Dallas, Texas. The company focuses on identifying and developing oil and natural gas reserves in underdeveloped or overlooked onshore US basins, operating across Texas, Oklahoma, and New Mexico with a portfolio of more than 1,100 operated and non-operated wells spanning over 40,000 gross acres. Its core technology is conventional and horizontal drilling plus well development, applied across a mix of oil-weighted assets (Loco Hills, Pinon Field) and gas-weighted assets (Brown Bassett, McGee Valley, Double Eagle), with well depths ranging from 1,500 ft to 22,000 ft.

The company's business model is commodity production and sales: it generates revenue by selling oil and natural gas produced from its wells directly to refineries, midstream processors, and commodity markets. A distinguishing structural feature is vertical integration through wholly-owned affiliates — TransPecos Gathering LLC (gas gathering), Century Gas Processing LLC (gas processing), and Longfellow Ranch Partners LP (mineral and royalty ownership) — which internalizes midstream margin and surface/mineral rights. Operations are run by a small (1-10 employee), family-oriented team with deep veteran leadership drawn from Riata Energy, SandRidge Energy, Shell, Schlumberger, and Occidental Petroleum.

Longfellow's go-to-market is relationship-driven rather than marketing-driven: there is no public pricing model, no disclosed customers, and no external institutional funding. The company has demonstrated a repeatable cycle of assembling acreage, developing it (e.g., the Nemaha horizontal project in the STACK Play), and monetizing at scale (Nemaha sold June 2018; Jameson and West Coast Properties sold December 2018), and more recently acquiring legacy Riata-developed assets back from Occidental (January 2022, 933 wells). Customers are effectively the commodity spot market; the only post-sale customer-facing function is a royalty relations portal serving mineral interest owners.

Scale indicators9 records

Recent moves10 records

Expansion highlights4 records

Broad incumbents

• Devon Energy: Major independent with significant Delaware Basin and Anadarko/STACK exposure — competing for the same overlooked onshore acreage in basins Longfellow targets, with a far larger horizontal development program.
• EOG Resources: Large independent E&P with material operations across the Permian, Delaware, and other Lower 48 basins where Longfellow operates — a scaled, public peer pursuing the same horizontal-development playbook across much larger acreage positions.
• Diamondback Energy: Pure-play Permian Basin E&P — a much larger, publicly traded peer with concentrated operations in the same Permian/Delaware sub-basins where Longfellow's Pinon, Brown Bassett, and Loco Hills assets are located.
• Civitas Resources: Independent E&P focused on the Permian (Delaware and Midland) and DJ Basin — a public peer pursuing similar horizontal development in legacy onshore US basins, though at meaningfully greater scale.
• Cimarex Energy: Independent E&P historically focused on the Permian (Culberson, Reeves counties) and Anadarko/Mid-Continent basins — overlapping with Longfellow's Permian and Oklahoma footprint; now combined with Civitas/Crescent Point.
• Permian Resources: Large Permian-focused independent formed from the Colgate/Concho legacy — competes for the same Delaware Basin and broader Permian acreage and infrastructure that underpins Longfellow's Pinon, Loco Hills, and Brown Bassett operations.

Direct peers

• SandRidge Energy: Direct predecessor of Longfellow — founded as Riata Energy in 1985 by Malone Mitchell, acquired by Tom Ward in 2006 and renamed SandRidge. Operates in the same Permian/Mississippian basins and shares much of Longfellow's institutional DNA and technical team lineage.
• Mewbourne Oil Company: Privately held Texas/Oklahoma-focused E&P that develops conventional and unconventional reserves in the Permian Basin, Anadarko Basin, and Texas Panhandle — a structurally similar family/private-backed operator with comparable basin focus and asset scale.
• Henry Resources: Private Texas-based E&P focused on conventional and unconventional oil and gas development in the Permian Basin and other onshore Texas plays — a closely comparable small private operator with horizontal drilling expertise in legacy acreage.
• Citation Oil & Gas: Privately held US E&P focused on mature, long-life oil fields across the Permian, Mid-Continent, and Gulf Coast — comparable in its focus on underdeveloped/overlooked conventional reserves and reliance on operational efficiency.
