Polymer flooding has proved economically and technically successful in numerous
enhanced oil recovery (EOR) projects, which can often increase oil recovery from 12 to 15 …

Context Polymer microgels are submicron-to-micron size, water-dispersible particles that are
formed through use of a crosslinking agent. Their permeability reduction capabilities, when …

As a result of research in the 1950s and 1960s, carbon dioxide (CO2) flooding has been
implemented at the pilot and project stage in the petroleum industry since the early 1970s. A …

Gels produced by crosslinking polyacrylamide solutions with chromium (III) have been
characterized by dynamic rheology studies. To vary the gel strength, different polymer …

The present paper describes the first field application of a new water shutoff technology
using size-controlled microgels for the treatment of a gas storage well. The treatment was …

Due to increased energy demand, it is vital to enhance the recovery from existing oilfields.
Polymer flooding is the most frequently used chemical enhanced oil recovery (cEOR) …

Reducing water production from hydrocarbon wells is one of the major requirements to
prolong the life span of production wells. Gel treatment is commonly regarded as one of the …

IFP water shutoff technology is based on the use of relative permeability modifiers (RPM's).
The technique consists of bullhead injection of polymer solutions into existing completions …

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 …

It is well established that treatment of porous rocks with gelled polymer systems can cause
the permeability of water at residual oil saturation to be reduced by one to three orders of …
