Findlay OH petroleum refining (NYSE: MPC); largest US refiner 3M barrels/day, CEO Maryann Mannen elected Chairman (Jan 2026), MPLX midstream MLP, Martinez renewable diesel conversion competing with Valero and Phillips 66.
Marathon Petroleum Corporation is a Findlay, Ohio-based petroleum refining and midstream company — publicly traded on the New York Stock Exchange (NYSE: MPC) as an S&P 500 Energy component — operating the largest crude oil refining system in the United States with 13 refineries and approximately 3 million barrels per day of crude oil processing capacity across Texas, Louisiana, Illinois, Michigan, Ohio, North Dakota, California, and Washington, along with a majority ownership interest in MPLX LP (NYSE: MPLX), a midstream pipeline, terminal, and marine vessel MLP that gathers, processes, transports, and stores crude oil, natural gas, and petroleum products. In a defining leadership development, Marathon Petroleum's board elected CEO Maryann T. Mannen as Chairman of the Board effective January 1, 2026, succeeding Michael Hennigan who retired after leading the company through the Speedway divestiture and pandemic recovery — consolidating corporate governance leadership in Mannen following her tenure as CEO during which she managed the company's operations and capital allocation strategy. Marathon Petroleum's large-scale refining system (including the Galveston Bay refinery in Texas City as the largest US refinery at 631,000 barrels/day) processes crude oil into gasoline, diesel, jet fuel, and specialty products distributed through branded Speedway (sold to 7-Eleven in 2021) and independent dealer networks and MPLX's logistics infrastructure.
Houston oilfield completions and drilling (NYSE: HAL) $22.9B FY2024 revenue; #1 US hydraulic fracturing, Zeus E-frac, international expansion, $4.0B adj. operating income competing with SLB and Baker Hughes.
Halliburton Company is a Houston, Texas-based oilfield services company — publicly traded on the New York Stock Exchange (NYSE: HAL) as an S&P 500 Energy component — providing products and services for the exploration, development, and production of oil and natural gas through two segments: Completion and Production (hydraulic fracturing, cementing, artificial lift, wireline logging) and Drilling and Evaluation (drill bits, directional drilling, formation evaluation, well construction planning) through approximately 50,000 employees in 70+ countries. In fiscal year 2024, Halliburton reported revenues of $22.9 billion and adjusted operating income of $4.0 billion, with North America (the most important market — driven by US shale completions) generating $8.6 billion and international operations (Middle East, Latin America, Africa, Europe) generating $14.3 billion. CEO Jeff Miller has led Halliburton's return to strong profitability following the COVID-19 oil demand collapse with a disciplined capital-light model: rather than owning all completion equipment (pressure pumping fleets, cementing units), Halliburton has entered long-term customer partnerships where major E&P operators (Pioneer, EOG, Devon, ConocoPhillips) commit multi-year completion work to Halliburton in exchange for deployment priority and dedicated crew relationships — reducing equipment idle time and Halliburton's capital requirements while securing predictable activity levels. Halliburton's Zeus electric fracturing fleet (E-frac using natural gas-powered electric motors to drive frac pumps rather than diesel engines) reduces NOx emissions and fuel cost for US shale operators — achieving 40-50% fuel cost reduction that operators increasingly specify as a sustainability requirement.
