This paper aims to assess the effectiveness of using advanced integrated production-data-analysis techniques for condensate-rich tight gas fields.
Bridging the gap between foundational guidance and real-world application, SPE’s Oil and Gas Reserves Committee is advancing PRMS education with a new, peer-reviewed training initiative. This article highlights the evolution of the PRMS knowledge base and introduces the PRMS Training Master Slides—a modular, instructor-led framework designed to improve consistency, cl…
Since the US arrested and removed Venezuelan President Nicolás Maduro on 3 January 2026, all eyes have turned toward the country’s vast oil reserves, the largest of any country. From 2005 to 2024, oil production in Venezuela fell by 70%, from 3.1 million B/D to just 0.9 million B/D. The race is on to bring production back, but aging infrastructure and expatriation pre…
