Continental Resources, led by billionaire Harold Hamm, has deepened its involvement in Argentina’s Vaca Muerta shale basin through an agreement with Pan American Energy (PAE) to acquire a 20% non-operating interest in four key blocks across Neuquén and Río Negro provinces. The partnership reinforces U.S. investment in Argentina’s unconventional oil sector and is positioned to accelerate development in one of the world’s premier shale formations.
