APA Corporation (NASDAQ: APA), historically known as Apache, operates its Midland office at 5301 W Interstate 20, Midland, TX 79703. Corporate headquarters are in Houston; the Midland office serves as the Permian Basin operational hub. As of year-end 2025, APA reported nearly 4,000 wells across 2.6 million gross acres in the Midland and Delaware sub-basins.
The Callon Petroleum acquisition closed April 1, 2024 for $4.5 billion (all-stock), with a synergy target of $150 million annually. The deal brought roughly 120,000 net Delaware Basin acres and 25,000 net Midland Basin acres into APA's footprint. Callon was historically a Houston-based independent — the merger consolidated some of Callon's headcount into APA's existing structure, with limited but real Midland-side flow.
For movers, APA / Callon is a smaller-volume integration relative to Diamondback-Endeavor or ExxonMobil-Pioneer, but still active. The Houston-to-Midland corridor handles most APA-related moves. The 5301 W I-20 location is convenient for employees living anywhere on the west or northwest side of Midland (closer to Grassland Estates and the Lone Star Trails corridor than to the Mockingbird Lane corridor).
