Spindletop Oil & Gas Co

President and CEO Chris Mazzini directs all capital allocation decisions, from royalty acquisitions to real estate purchases and credit positions. As the firm’s long-tenured executive, Mazzini has maintained continuity in the strategy of recycling energy-generated cash flows into hard assets, with no external investment committee disclosed.

Spindletop functions as both. It holds producing overriding royalty interests in oil-and-gas properties, generating operating income, but deploys that income into commercial real estate and private credit investments — a blend that mirrors a permanent-capital family office more than a traditional exploration-and-production firm. The company has never defined itself strictly as a family office, yet its indefinite hold periods and lack of outside limited partners give it that de facto profile.

The firm sources opportunistically, often through direct relationships and Texas-based networks rather than competitive auction processes. Because it uses internally generated cash rather than committed fund capital, Spindletop can transact quickly on off-market commercial properties and private credit placements without the timeline pressures of a traditional fund structure.

The real estate portfolio concentrates on Texas metro areas, with additional exposure to surrounding Sun Belt markets. The oil-and-gas royalty interests remain rooted in legacy fields across Texas and Louisiana. The firm has not disclosed significant international holdings, maintaining a heavily regional, contiguous footprint that leverages local market knowledge.

Spindletop has not disclosed accepting outside limited partner capital. Its public equity structure provides permanent access to balance-sheet capital, eliminating the need for fund closes or partner distributions. This self-funded model means co-investment arrangements are not part of its disclosed strategy, though the firm could theoretically partner on specific acquisitions as a balance-sheet participant.
