Enhanced recovery
This paper presents a clear and consistent method for determining dead and live crude EACNs using a single reliable method, highlighting a graphical way to determine the optimal salinity and its uncertainties using real data.
This paper presents a unique investigation into determining the sufficient concentration of hardness ions required to significantly reduce the adsorption of acrylamide-tertiary-butyl-sulfonate-based polymer with a focus on mitigating polymer retention in carbonate formations using softened brine.
India’s state oil company is accepting proposals from potential technical service partners until 15 September for EOR projects in the Arabian Sea.

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 describes the stimulation of a horizontal water-injection well with a limited-entry-liner completion in an onshore carbonate reservoir using a large volume of viscoelastic diverter-acid fluid system ahead of the main acid stage.
-
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.
-
The EOR scene has evolved as well. Low-salinity waterflooding, originally thought to apply only in certain sandstone reservoirs, appears to be able to unlock additional reserves also for some carbonate formations, although the fundamental mechanisms are different.
