Reservoir
Industry experts at URTeC assessed more than a decade of unconventional growth while discussing where productivity gains will come from next.
The technology has passed its first phase of qualification, with 84 nodes placed on the seafloor at a depth of 2,000 m to acquire 4D seismic data in the pre-salt Santos Basin.
Chevron and Halliburton describe how they built and deployed the fully autonomous closed-loop fracturing system that enables subsurface-driven optimization.

This paper reviews existing literature, the operator’s records, service-company data, and simulation studies to assess the risk of using seawater in carbonate acidizing.
-
The paper describes a project in which extremely challenging stimulations were performed in a fractured tight carbonate in a complex strike/slip stress faulting regime with high tectonic stresses.
-
This study provides the first experimental evidence that in-situ combustion is feasible in Permian shale under realistic rock–fluid conditions.

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…
