What EIV Capital does
EIV Capital, LLC is a Houston-based private equity firm founded in 2009 by Patricia Bryant Melcher that invests across the North American energy value chain via two distinct fund vehicles: a value-add energy infrastructure strategy (gathering, processing, transportation, storage, and marketing of oil, natural gas, and refined products) and a non-operated upstream oil and gas strategy pursued through its EIV Resources platform. The firm operates as an SEC-registered investment adviser and provides advisory services solely to its privately offered funds, with capital sourced from pension funds, insurance companies, endowments, foundations, family offices, and asset managers. As of April 2026, EIV closed Fund V and EIV Resources II at approximately $1.1 billion in combined capital commitments, bringing total committed capital under management to approximately $3 billion. The firm's products are investment funds and the 34 active portfolio companies (plus 21 realized) they own across midstream, upstream, oilfield services, renewable natural gas, renewable chemicals, and energy software sub-sectors; portfolio stewardship is delivered by an embedded investment team plus a dedicated EIV Resources operating staff (CFO, Controller, Director of Land, SVP Engineering, SVP Land, VP Engineering, CTO). Revenue is generated through management fees on committed capital, transaction and monitoring fees, and capital appreciation realized through portfolio exits such as H2O Midstream (to Delek Logistics, August 2024) and Bayou Midstream operating subsidiaries (to Bridger Pipeline, May 2024).

EIV Capital product offering
Product offeringCore offering
EIV Capital is a multi-strategy energy private equity firm that raises capital from institutional investors and deploys it into North American energy businesses. Its core offerings are two private fund vehicles — EIV Capital Fund V, LP (value-add energy infrastructure: midstream gathering, processing, transportation, storage and marketing) and EIV Resources II, LP (non-operated upstream oil and gas: non-operated working interests, mineral and royalty interests) — together with an internal upstream operating platform (EIV Resources) and a portfolio of directly held midstream, infrastructure, renewable natural gas, and energy value-chain companies.
Product overview
EIV Capital is a multi-strategy Houston-based private equity firm (founded 2009) that does not sell software or technology products in the traditional sense; instead, its "offerings" are investment vehicles and the portfolio companies they own. The firm's current flagship products are two recently closed fund vehicles — EIV Capital Fund V, LP (a value-add energy infrastructure fund led by Managing Partners David Finan and Patti Melcher) and EIV Resources II, LP (a non-operated upstream energy investment fund led by Partner Claire Harvey) — which together raised approximately US$1.1 billion in capital commitments at final close in April 2026. These funds sit atop an underlying platform — EIV Resources — the firm's upstream oil and gas investing platform initiated in March 2021, which provides customized capital solutions to oil and gas producers (non-operated working interests, mineral and royalty interests). The active portfolio of investee companies — including Bayou Midstream II, Intensity Infrastructure Partners, Penrose Midstream Partners, Viridis Chemical, Vivid Energy (d.b.a. Enersponse), Canes Midstream, Atlas Pressure Control, AMP Americas II, Fullstream Energy, and CAM Integrated Solutions — represents EIV Capital's named sector exposure across energy infrastructure, upstream oil and gas, and the broader energy value chain. Realized portfolio investments (H2O Midstream, Bayou Midstream I, Woodland Midstream, EcoVapor, Datagration, etc.) illustrate the firm's full investment lifecycle.
