Why this directory exists
A producer, pressure-pumping fleet, gas processor, pipeline, LNG terminal, utility, trader, engineering contractor, data provider, and AI company can all participate in the same energy outcome. Conventional directories separate them by a single label or list them without explaining what they actually control.
BTU Graph starts with the system. Companies connect to sectors, capabilities, markets, regions, and value-chain stages. Each profile explains the organization's operating role in plain language and links material facts to current public evidence. The goal is to make company discovery faster without turning editorial judgment into a ranking.
Ownership and commercial disclosure
BTU Graph is owned and published by Oil Price API, a commercial energy-data API. Relevant pages contain one labeled callout to Oil Price API. Those links carry campaign parameters and a random click identifier so the publisher can measure whether the directory creates useful product discovery.
Oil Price API's ownership is visible because it changes how readers should interpret the site. It does not entitle Oil Price API to fabricate demand, endorsements, or customer relationships, and it does not let any company buy rank or coverage.
What BTU Graph covers
The first company edition spans exploration and production, field services and equipment, midstream infrastructure, LNG, refining, power, renewables, engineering and construction, trading and logistics, research and data, AI and analytics, and energy software. Coverage can expand only when current public evidence supports a useful profile and a sector has enough depth to deserve an indexable page.
BTU Graph does not aim to become an energy-news publication or replicate Oil Price API's benchmark and API pages. It maps who participates in energy and what they do. Current prices, API documentation, and code-level market-data access belong on Oil Price API.
