often known simply as Ameredev—was a leading Austin-based independent oil and gas exploration and production company, specializing in the core of the Delaware Basin within the Permian. At its peak, Ameredev managed a highly contiguous footprint of over thirty-three thousand net acres, delivering strong output—around twenty-five thousand to twenty-six thousand (25,000 – 60,000) barrels of oil equivalent per day, with roughly sixty-five percent (65%) oil—making it one of the most prominent private operators in the region.

In June 2024, Matador Resources announced a strategic acquisition of Ameredev’s assets for approximately one point nine billion dollars 1.8 Billion USD (closing at one point eight three billion after adjustments), folding in those high-quality producing properties, reserves, and midstream interests like a stake in Piñon Midstream. This deal solidified Matador’s dominance in the Delaware while marking the end of Ameredev’s standalone era—though its legacy of disciplined development and sour-gas expertise lives on in the integrated operations today.
