This paper provides an introduction to the topic of water shutoff and conformance
improvement. After indicating the volumes of water produced during oilfield operations, a …

Polymer flooding is a promising enhanced oil recovery (EOR) technique; sweeping a
reservoir with a dilute polymer solution can significantly improve the overall oil recovery. In …

Several publications by authors in the field of petrochemical engineering have examined the
use of chemically enhanced oil recovery (CEOR) technology, with a specific interest in …

This review comprehensively summarizes potential applications of SiO2–polymer
composites especially in oil industries: enhanced oil recovery (EOR), loss circulation (LC) …

Novel conformance control and polymerflood applications that exploit the pH-sensitivity of
partially hydrolyzed polyacrylamide (HPAM) are proposed. The key feature of this process is …

Polyelectrolytes are water-soluble polymers that form molecular networks by association in
solution. The properties of such polymers are very sensitive to the pH and ionic content of …

Water production from oil and gas reservoirs is increasing worldwide, as more reservoirs are
becoming mature. In order to control water production, polymers and gels are often injected …

This paper describes the mechanism for disproportionate permeability reduction (DPR).
Recent papers have discussed possible DPR mechanisms. Most of the papers conclude that …
