**Company Overview** — ExxonMobil formed through the 1999 Exxon-Mobil merger; descendants of John D. Rockefeller's Standard Oil. Headquartered in Houston, TX (NYSE: XOM), the company operates across all petroleum industry segments: upstream exploration/production, downstream refining/marketing, and chemicals manufacturing.

**Pioneer Acquisition Impact** — The 2024 acquisition of Pioneer Natural Resources transformed ExxonMobil into the Permian Basin's largest operator with 1.4 million net acres and 1.3+ million barrels/day production. Former Pioneer mineral owners now receive payments from ExxonMobil under unchanged lease terms.

**Primary Operating Areas** — Permian Basin operations span Midland (Spraberry/Wolfcamp), Martin (core Midland Basin), Reagan, Upton, Loving, and Reeves counties in Texas, plus Lea and Eddy counties in New Mexico's Delaware Basin. Bakken operations target horizontal wells in McKenzie, Williams, and Mountrail counties. Gulf of Mexico includes major deepwater platforms.

**Advantages for Mineral Owners** — Financial stability as the largest U.S. oil company ensures consistent operations; well-established royalty payment systems deliver on-time payments with detailed statements; online portal provides digital access to documents; large owner relations department offers toll-free support.

**Considerations** — Large bureaucracy may slow issue resolution compared to smaller operators; corporate processes for division order changes and address updates can require multiple steps; Pioneer integration may cause temporary delays; standardized lease terms offer less negotiation flexibility.

**Owner Relations** — Contact 1-800-252-1800 (Monday–Friday, 8 AM–5 PM CT) or mail to P.O. Box 2180, Houston, TX 77252-2180. Online portal enables statement viewing, information updates, and tax document access.

**Working with ExxonMobil Tips** — Set up online portal access; maintain organized copies of leases, division orders, and statements; use your unique owner number when calling; review statements for accuracy on production, prices, and deductions; report address changes promptly through portal or in writing; allow 60–90 days for Pioneer merger system integration.

**Denbury Acquisition** — November 2023 acquisition of Denbury Resources for $4.9 billion brought CO2 transportation/sequestration infrastructure. ExxonMobil now operates Mississippi Jackson Dome CO2 EOR floods including Heidelberg East (Jasper County), Eucutta East (Wayne County), and Brookhaven (Lincoln County) field units under "ExxonMobil Low Carbon Solutions."

**Payment Timing** — Royalties typically paid monthly, 60–90 days after production, following state regulations. Texas requires payment within 120 days of first production, then monthly thereafter.
