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 …

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 …

Polymer gel systems as water management materials have been widely used in recent
years for enhanced oil recovery applications. However, most polymer gel systems are …

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 …

Boron (B), normally present in ground water and sea water, is a vital micronutrient for plants,
but is also toxic in excessive amounts. Under typical conditions, aqueous boron is present …

The objective of this study was to engineer a model anti-HIV microbicide (tenofovir) loaded
chitosan based nanoparticles (NPs). Box–Behnken design allowed to assess the influence …

Polyacrylamide hydrogel used in conformance control is subjected to poor stability at an
elevated temperature. In this paper, nanosilica has been found to be a very effective …

聚合物凝胶调剖技术可以有效治理水驱油层水流优势渗流通道并提高采收率.
