Enhanced recovery
Three experts were recognized with the Pioneer Award at the 2026 SPE Improved Oil Recovery Conference in Tulsa for their technological contributions to improved oil recovery.
Acting director of the new center Ale Hakala outlines the research priorities guiding the newly established center’s focus on production enhancement technologies.
The authors write that deployment of artificial-intelligence-based high-gas/oil ratio well-control technology enabled stabilization of well performance and maintenance of optimal production conditions.

Pilots and papers are plentiful, but the shale sector has no big enhanced oil recovery projects to speak of. It may just have to stay that way for a while. -
This study proposes a hybrid model that combines the capacitance/resistance model, a machine-learning model, and an oil model to assess and optimize water-alternating-gas (WAG) injectors in a carbonate field.
-
This paper describes a hydraulic fracturing pilot project using a technique that generates higher fracture conductivity to reduce the drawdown during production and improve connection through laminations.
-
This paper presents a case study of a North African oil field producing from two Ordovician sands with differing permeabilities where significant benefit was achieved by fracture stimulating one or both intervals in two wells.
-
This paper details a successful pilot to improve long-term well performance using acid stimulation aided by a tailored metal oxide nanoparticle-based fluid in the Wolfcamp A formation.
-
In this paper, the authors propose polymer-assisted water-alternating-gas (WAG) injection as an alternative method to reduce gas mobility while reducing the mobility of the aqueous phase and, consequently, improving WAG performance.
-
The authors of this paper study the effect of solids particles on oil/water separators and on produced-water treatment.
-
The authors present an efficient microfluidic platform to measure high-quality minimum miscibility pressure data of CO2 with various impurities faster and easier.
-
This study introduces a detailed model to capture the physics and chemistry of acid flow in complex horizontal wells completed in carbonate formations.
-
The authors of this paper describe a project in which far-field diverters were pumped to mitigate wellbore sanding and production loss in existing parent wells.
