Our business divisions


This is where it all begins. Where the story of safely and responsibly meeting the global demand for energy starts. Across the upstream, our geologists, engineers and scientists work tirelessly to explore for and develop oil and natural gas using innovation and industry-leading technology.

Upstream business lines

Our Upstream business is organized into five businesses: unconventional, deepwater, heavy oil, liquefied natural gas (LNG), and conventional. This organizational model is underpinned by deep technical and commercial capabilities along each value chain.

First oil in Guyana

University of Texas, Austin, fellow Emily Beckham
Capital-efficient cube development across multiple stacked producing horizons maximizes the recovered resource by minimizing or removing potential parent-child production impacts caused by pressure depletion. Applying this approach at scale differentiates our operations from competitors. Above, seven rigs drill stacked targets within our Permian Basin acreage. Simultaneously accessing multiple shale layers reduces costs and minimizes surface footprint.

Exxon Mobil Corporation has numerous affiliates, with many names that include ExxonMobil, Exxon, Mobil, Esso and XTO. For convenience and simplicity those terms and terms such as Corporation, company, our, we and its are sometimes used as abbreviated references to specific affiliates or affiliate groups.
