For the past decades, long-term water flooding processes have led to water channeling in
mature reservoirs, which is a severe problem in oilfields. The development of better plugging …

As a promising method of carbon emission reduction, carbon capture, utilization and storage
(CCUS) is an important technology to achieve carbon neutrality. CO 2 geological storage is …

Drilling fluid circulation loss is referred to as “the most severe problem in drilling of oil and
gas wells”, as a routine solution, loss circulation materials are added to fill any fractures and …

Polymer gels with suitable viscoelasticity and deformability have been widely used for
formation plugging and lost circulation control, profile control, and water shutoff. This article …

Polymer gel systems have been widely applied to control excessive water and improve oil
recovery (IOR) in petroleum reservoirs. They are usually divided into two main types, in-situ …

Polymer gel has been established as water‐blocking agents in oil recovery application. In
this practice, a mixture known as gelant is injected into target area and set into a semisolid …

Emulsified water‐in‐oil (W/O) systems are extensively used in the oil industry for water
control and acid stimulation. Emulsifiers are commonly utilized to emulsify a water‐soluble …

Several crosslinked polymer gels have been developed over the last 5 decades to address
the different technical challenges in oil reservoirs especially conformance control …

Acrylamide-based polymer gels have been applied to control the preferential flow in the
subsurface for decades. However, some commonly used crosslinkers, such as Cr (III) and …

High water-cut oil production is one of the major issues in the petroleum industry. The
present study investigates different profile control solutions, with an emphasis on selective …
