Conventional and unconventional hydrocarbon rocks have complicated pore structures with
heterogeneities distributed over various length scales (from nanometre to centimetre or even …

In todays' world, there is an increasing number of mature oil fields every year, a
phenomenon that is leading to the development of more elegant enhanced oil recovery …

Excessive water production is one of the main problems of mature reservoirs, which reduces
hydrocarbon production and economic reservoir lifetime, and may pose severe …

This study presented an organic–inorganic hybrid preformed particle gels (PPG) by coating
a tetramethyl orthosilicate layer on acrylamide-based PPG to control the swelling rate of …

Gel treatment is an effective way to attack excessive water production in many mature
oilfields around the world. Selective penetration is desired for successful gel treatments …

In order to develop a high-performance temporary plugging agent (TPA) in a low-
temperature-dense reservoir in an oilfield, this paper reported the quaternary ammonium …

Excessive water production increases operational costs and causes environmental issues.
The water source can be from either aquifer encroachment or breakthrough during …

A cross-linked amphiphilic polyelectrolyte colloidal gel (CG) exhibits significant potential for
diverse applications, including hydrophobic drug delivery and oil recovery, owing to its …

This study aims to numerically determine the roles of the geochemical reactions during the
injection of a strong acid into a sandstone sample. As a case study, we used laboratory …

Waterflooding is widely implemented to enhance oil recovery. The displacement efficiency of
this method depends on multiple factors, including makeup water properties, native oil, and …
