Alkali Polymer Flooding of a Romanian Field Containing Viscous Reactive Oil Open
The study demonstrates the significant enhancement in oil production from a Romanian oil field using alkali–polymer (AP) flooding for reactive viscous oil. We conducted comprehensive interfacial tension (IFT) measurements across various al…

Selecting EOR Polymers through Combined Approaches—A Case for Flooding in a Heterogenous Reservoir Open
This work uses micromodel, core floods and Field-Flow Fractionation (FFF) evaluations to estimate the behaviour and key elements for selecting polymers to address heterogenous reservoirs. One of the approaches was to construct two-layered …

Optimizing Polymer Costs and Efficiency in Alkali–Polymer Oilfield Applications Open
In this work, we present various evaluations that are key prior field applications. The workflow combines laboratory approaches to optimize the usage of polymers in combination with alkali to improve project economics. We show that the per…

Recovery Observations from Alkali, Nanoparticles and Polymer Flooding as Combined Processes Open
We have studied wettability alterations through imbibition/flooding and their synergy with interfacial tension (IFT) for alkalis, nanoparticles and polymers. Thus, the total acid number (TAN) of oil may determine the wetting-state of the r…

Wettability Changes Due to Nanomaterials and Alkali—A Proposed Formulation for EOR Open
We investigated the usage of two silica nanomaterials (surface-modified) and alkali in enhanced oil recovery through Amott spontaneous imbibition tests, interfacial tension (IFT) measurements, and phase behavior. We evaluated the wettabili…

Experimental approach for assessing filter-cake removability derived from reservoir drill-in fluids Open
Predicting formation damage in cased-hole and open-hole completion wells is of high importance. This is especially relevant when the damage is caused by reservoir drill-in fluids hence being well-bore induced. Cake filter removal has prove…
