Quintana Infrastructure & Development builds on nearly 85 years of history in asset stewardship to enrich customers, partners and society.


Quintana Minerals Corporation (QMC) is the administrative company of the Corbin J. Robertson, Jr. family. QMC allocates dedicated employees to various operating and investment entities. QMC’s origins date back to Quintana Petroleum Corporation and its discovery of the Tom O’Connor Field in the 1930s by Hugh Roy Cullen. Quintana Infrastructure & Development, LLC (QID) is an investment holding and operating company owned by William K. Robertson and organized in 2011. QID is part of a continuum of investment activities that started in 1999.


QID is an extension of Quintana’s brand, reaching into energy, natural resource and industrial infrastructure industries. QID is not a fund; rather, QID is a holding company making investments and, in certain cases, operating assets for itself or on behalf of like-minded partners. QID is not an affiliate of Quintana Minerals Corporation, Quintana Carbon & Minerals Trading Limited, Quintana Capital Group, Ltd., or Quintana Shipping Ltd. These are distinct entities for distinct purposes, although they share a name and the participation of the Robertson family.


QID’s purpose is to safely, responsibly and creatively invest capital and/or manage assets that deliver superior returns for their stakeholders. We focus on management and field-level personnel who make honest, deliberate, nimble and value-guided decisions. Capital, assets and/or equipment are instruments through which our people serve our customers.

QID aims to steward assets for the long-term so that customers will be happy today and comfortable in sustaining their commitments tomorrow. QID remains opportunistic in its investment selection, and importantly in its timing. QID has no forcing function with respect to investment hold periods, preferring to prepare for a long-term hold, but ready and willing to monetize as market conditions precipitate favorable realization outcomes. QID maintains an eye for generational assets, or those that offer long-term, stable and inflation-protected returns.
