Casillas Petroleum

What Casillas Petroleum does

Casillas Petroleum Corp. is a privately held, Tulsa-headquartered (401 S Boston Ave #2400) oil and gas exploration and production company founded in 1986 by Greg Casillas. The company focuses its operations on the Mid-Continent and Hugoton basins and self-describes as a regional leader in those areas, deriving its positioning from decades of accumulated geological research, technical expertise, and capital discipline rather than from any disclosed proprietary technology, digital platform, or AI/ML capability.

The business model is straightforward upstream commodity production: Casillas acquires oil and gas properties throughout the Lower 48 states, operates them using its in-house technical team (with named regional contacts in Oklahoma and Kansas and an engineering function), and sells the resulting crude oil and natural gas to downstream buyers — refineries, processors, utilities, and industrial purchasers — through pipeline and transportation infrastructure. Revenue is therefore a direct function of commodity prices and production volumes, with no disclosed hedging program, offtake counterparties, or pricing model. The company's primary commercial "customer" in the partnership sense is actually the universe of oil and gas property owners and mineral rights holders across the Lower 48, with a formal owner relations channel ([email protected]) supporting acquisition and partnership inquiries.

The firm is controlled by founder Greg Casillas, with no disclosed institutional investors, parent company, funding rounds, subsidiaries, patents, or regulatory actions in the source material. Operating status is active, with a corporate emphasis on safe, ethical, and environmentally responsible operations. Public-facing touchpoints are limited to a corporate website (casillaspetro.com) and a LinkedIn company page; there are no mobile applications, public APIs, or disclosed technology integrations.

Direct peers

• Mewbourne Oil Company: Privately held US independent E&P focused on the Mid-Continent and other US basins, with an acquisition-and-operate model structurally similar to Casillas Petroleum.
• Citation Oil & Gas: Privately held US independent E&P that operates mature, long-life oil-producing properties across multiple states, mirroring Casillas Petroleum's mature-basin, acquisition-driven approach.
• SandRidge Energy: Independent E&P with a historical focus on the Mid-Continent region, making it a geographically and operationally comparable peer to Casillas Petroleum's Mid-Continent-centric footprint.
• Hilcorp Energy: Large privately held US E&P focused on acquiring and optimizing mature, long-life oil and gas properties — directly comparable business model to Casillas Petroleum's property-acquisition strategy in mature basins.

Broad incumbents

• Chesapeake Energy: Major US E&P active across multiple unconventional basins, including historically in the Mid-Continent; an incumbent peer for Casillas Petroleum's Lower 48 acquisition universe.
• Range Resources: US-focused independent E&P with multi-basin operations; comparable operating model as an independent producer targeting onshore US hydrocarbon assets.
• Devon Energy: Major US E&P with a broad multi-basin portfolio including Mid-Continent operations; comparable end-market exposure but far larger and more diversified than Casillas Petroleum.
• Murphy Oil: Independent E&P with onshore US operations alongside international assets; comparable as a smaller-scale public independent E&P competing in the same domestic upstream ecosystem.
• Continental Resources: Large US E&P (now privately held) operating across multiple Lower 48 basins; overlaps with Casillas Petroleum in onshore US crude production but at materially larger scale.

Others

• EagleClaw Midstream: Midstream operator in the Permian/Delaware basin; included as an ecosystem participant whose gathering and processing infrastructure supports Lower 48 producers like Casillas Petroleum.
