Displacement Efficiency in Eccentric Annuli

Volume 11: Petroleum Technology, 2020
Abstract A successful primary cementing job requires an efficient fluid displacement process in order to place cement in the annulus between a casing or liner and the formation around the wellbore. This operation is a critical part of the well construction and due to the hardening properties of cement there will be no second chance with ...

Impact of Salinity on Waterflood Displacement Efficiency

SPE Offshore Europe Conference & Exhibition, 2023
Abstract Fluid properties are among the main parameters that influence waterflood performance. This paper aims to investigate the impact of salinity on displacement efficiency by understanding the effects on physical properties. Besides salinity, dissolved CO2 and temperature effects are also evaluated. Based on these, the paper assesses

How Viscoelastic-Polymer Flooding Enhances Displacement Efficiency

SPE Journal, 2015
SummaryIncreasing flooding-solution viscosity with polymers provides a favorable mobility ratio compared with brine flooding and hence improves volumetric sweep efficiency. Flooding with a polymer solution exhibiting elastic properties has been reported to increase displacement efficiency, resulting in a sustained doubling of the recovery enhancement ...
