What Rockcliff Energy does
Rockcliff Energy III LLC is a private Houston-based upstream oil and gas company formed in 2024 as a successor to the original Rockcliff Energy (which was acquired by TG Natural Resources in December 2023). The company is backed by long-time financial sponsor Quantum Capital Group, whose partners (Alex Jackson, Blake Webster, Basak Kurtoglu) sit on the board alongside an operating leadership team led by President & CEO Sheldon Burleson and Executive Chairman Alan Smith.
The company's core product is the operation of unconventional oil and natural gas assets in the Lower 48 United States, with a current operational footprint concentrated in the East Texas Haynesville Shale following its October 2025 acquisition of Pine Wave Energy Partners' East Texas package (25 operated wells, ~29,000 net acres, ~100 MMcf/d net production, and a controlling interest in San Augustine County gathering pipelines). Rockcliff generates revenue through the production and sale of natural gas and incidental oil into commodity energy markets via pipeline infrastructure, with no disclosed pricing model, hedges, or offtake agreements.
Go-to-market is enterprise field sales-style dealmaking: identifying, acquiring, and operating producing asset packages from upstream peers, then selling output into undifferentiated gas/oil markets. Distribution is via owned and third-party pipelines in East Texas. The company positions itself on responsible operations and ESG stewardship (Project Canary deployment, sustainability disclosures, Hart Energy ESG participation), targeting energy markets broadly as its customer segment. Headcount of 101–250 and a single Houston headquarters at 700 Milam Street, Suite 2000 are consistent with a mid-sized private E&P in build-out phase.
