Reservoir
The industry clearly needs creative solutions that are affordable and operationally flexible, and the three papers selected for this Technology Focus highlight some innovative approaches that aim to unlock those extra barrels.
This case study from SLB and offshore producer PRIO describes the longest openhole section in Latin America with the highest extended-reach drilling ratio in Brazil’s history.
This paper details a new enhanced oil recovery method piloted successfully by several operators in the Bakken and recently implemented in the Midland play of the Permian Basin.
-
This paper presents a case study of oriented tubing-conveyed perforation followed by an acidizing operation to overcome technical challenges posed by a depleted reservoir targeted for a carbon capture, utilization, and storage project. -
This paper describes the use of encapsulated polymer technology to address the issues of shear degradation and injectivity integrity faced in the application of polymer flooding in an offshore development context.
-
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.
-
The works highlighted in this year’s Acidizing feature demonstrate novel, diverse innovations in sustainability, enhanced productivity, and logistical efficiency by authors of SPE conference papers.
-
The paper presents the design and successful field deployment of the first closed-loop hydraulic fracturing program.
-
This paper reviews fracturing-program design, completion technology, real-time data collection, data integration, and lessons learned for the Pikka development on the North Slope of Alaska.
-
This paper presents a case study of a tool-free fishbone fracture stimulation technology using sand jetting and acidizing in openhole wells, providing a technical solution for low-permeability and complex-lithology carbonate reservoirs in the Middle East.
-
New insights from Chevron, Occidental Petroleum, and others at the SPE Improved Oil Recovery Conference highlight the different paths companies are using to squeeze more out of tight rocks.

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…
