Increasing offshore oil and gas exploration and development in harsh/Arctic environments
require more effective offshore produced water management, as these environments are …

The use of a polymer gel is an effective method for water shutoff in mature oilfield
development. As for fractured reservoirs, in order to mitigate the filtration of gelant (fluid …

Using gel as the water shutoff agent has been widely reported in the aspect of enhanced oil
recovery (EOR) of the development of mature oil fields. Cross-linkers such as chromium (III) …

In this study, a thixotropic and high-strength gel system (THSG) is developed, which is
experimentally proven to be feasible for conformance control in fractured reservoirs. The …

The use of gel as the water shut-off agent has been widely reported in enhanced oil
recovery (EOR) of mature oil fields. The organically cross-linked polymer systems are …

In fractured reservoirs, the fracture size distribution is wide with strong heterogeneity, and
wide fractures are not easily plugged. Conventional plugging methods have limitations in …

Using mature Cr 3+/partially hydrolyzed polyacrylamide (HPAM) gel can reduce filtration for
water shutoff in the fractured reservoir. Whether the mature gel can act as a fluid-loss-control …

Polymer based gels have been widely applied in the fractured reservoir for water shutoff and
enhancing oil recovery. In this study, a polymer gel system with long-gelation time and high …

In previous study, we have discussed the gelation performance of the polyethyleneimine
(PEI) cross-linking partially hydrolyzed polyacrylamide (HPAM) gel system. The major goals …

The study presented the impacts of various parameters like compositional combinations of
PHPA (partially hydrolyzed polyacrylamide), organic cross-linker (hydroquinone-HQ and …
