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 …

Gel treatment has been widely applied in mature oilfields to improve sweep efficiency and
control water production. Correct numerical simulation is of major importance to the …

Reservoir development is increasingly moving towards the heavy oil resources due to the
rapid decline in conventional oil reserves. With the production of conventional low gravity …

Unwanted water production is a serious issue in oil-and gas-producing wells. It causes
corrosion, scale, and loss of productivity. One method of treating this problem is to …

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 …

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 …

Using a chemical water shutoff method is one of the most effective ways to control formation
water and enhance gas recovery. Numerous water shutoff agents have been applied to …

Organically crosslinked gels have been used to control water production in high temperature
applications. These chemical systems are based on the crosslinking of a polyacrylamide …

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 …
