ExxonMobil

ExxonMobil is a publicly traded integrated energy company headquartered in Spring, Texas. Its U.S. upstream onshore business is operated principally through its XTO Energy subsidiary, which retains the XTO name for many of its operations and on royalty payment statements. Following the May 2024 close of the Pioneer Natural Resources acquisition, ExxonMobil became one of the largest mineral leaseholders in the Midland Basin of the Permian.

The company’s onshore U.S. footprint stretches across multiple producing basins: the Permian (Midland and Delaware), the Bakken in North Dakota, the Haynesville in East Texas and North Louisiana, and the Marcellus and Utica in Appalachia. ExxonMobil’s onshore activity in any given basin is sometimes branded ExxonMobil, sometimes XTO, and in legacy paperwork can still appear as Pioneer.

In the Permian Basin, ExxonMobil’s position now centers on the former Pioneer acreage in the core of the Midland Basin (Midland, Martin, Reagan, and Upton counties in Texas) along with longer-held XTO acreage in the Delaware Basin (Reeves, Loving, Eddy, and Lea counties across Texas and New Mexico). In the Bakken, the legacy XTO position concentrates in Williams and McKenzie counties in North Dakota.

The company’s natural gas position in the Haynesville covers parts of DeSoto and Caddo parishes in Louisiana and adjacent East Texas counties. In Appalachia, XTO operations extend across the Marcellus and Utica plays in Pennsylvania, Ohio, and West Virginia. On a single owner statement, it is not unusual to see XTO listed as the operator across multiple states.

Receiving royalty checks from ExxonMobil means you own a fractional interest in producing wells operated by ExxonMobil or by its XTO Energy subsidiary. ExxonMobil’s U.S. onshore upstream business runs principally through XTO, which retains its own brand, its own statement formatting, and its own owner relations channel even though both are part of the same parent company. A check from XTO and a check from ExxonMobil are administered by the same operator at the parent level.

ExxonMobil’s onshore footprint stretches across multiple producing basins in our 12-state coverage. The Permian Basin in Texas and New Mexico is the largest position, concentrated in the Midland sub-basin following the 2024 Pioneer Natural Resources acquisition. The Bakken in North Dakota and the Haynesville in Louisiana and adjacent East Texas counties round out the oil and gas footprint, while the Marcellus in Pennsylvania and the Utica in Ohio and West Virginia cover the Appalachian gas fairway.

XTO operates across most of this footprint, which is why royalty checks from ExxonMobil-operated wells frequently show the XTO name on the statement. The 2024 Pioneer acquisition was material for many Midland Basin owners. Pioneer was one of the largest mineral leaseholders in the sub-basin, and the transaction transferred operator of record on a substantial number of producing wells from Pioneer to ExxonMobil. Some royalty owners may still see the Pioneer name on older paperwork. The 2010 XTO acquisition is older but its branding effects persist: XTO continues to issue statements under its own name despite being part of ExxonMobil for over a decade.

If you have a question about a specific ExxonMobil-paid or XTO-paid interest, the parent company maintains an owner relations channel for account-level questions (decimal interest, statements, address changes, probate updates), and XTO has historically operated its own owner relations process for royalty owners on XTO-administered wells. The state regulator well database confirms operator of record by API number. We are happy to help you read what you have and identify what is missing if the XTO and Pioneer naming history makes the chain hard to follow.
