Upstream Energy Services

What Upstream Energy Services does

Upstream Energy Services (UES) is a Houston-based, privately held oil and gas marketing agency founded in 1995 that provides outsourced marketing services for natural gas, NGLs (natural gas liquids), and crude oil on behalf of North American exploration and production (E&P) producers. The firm serves more than 100 E&P clients and operates three core service lines — Natural Gas Marketing (commission-based sale of gas production to optimize realized pricing), NGL Marketing (support functions for gas processing, gas gathering, and midstream facility operators), and Crude Marketing (valuation and operator transition support for purchasers of producing assets) — delivered through a direct, relationship-based enterprise sales motion. The firm does not disclose pricing; engagement terms are quote-based and tied to transaction volumes rather than seats.

UES monetizes primarily via transaction or commission fees tied to the volume or value of hydrocarbons it markets, with revenue streams across all three commodity lines. Go-to-market is enterprise direct sales targeting North American E&P companies, midstream operators, and asset purchasers, with services customized per client. The firm also operates the Mansfield Analytics Portal (MAP), a proprietary, web-based client portal that delivers market intelligence, client-specific statements and executive summaries, and maps and reports for tracking market positions; MAP is positioned as a client-service differentiator rather than a standalone product. The firm is owner-operated at a small scale (11–50 employees), has no public listing, no disclosed institutional capital, and no documented M&A, partnership, or leadership-change activity in the supplied data.
