in this paper, polyacrylamide/chromium acetate gel polymer system was prepared as water shut-off system to control water production in one of the iranian oil reservoirs condition. effect of various parameters such as temperature (90 °c) and water formation from view point of salinity and divalent cations, was evaluated on the gelation kinetic and gel strength using bottle testing method. the re...

A hydrogel was prepared by crosslinking aqueous solutions of sulfonated polyacrylamide/chromium triacetate for use in water shut off operations. Gel swelling and the effects of salinity, injection time and flow rate on residual resistance factor (Frr) were investigated. In the presence of electrolytes, gel swelling decreased by about 80%. Results showed that oil permeability increased as inject...

A lack of regular access to clean and safe water sanitation is a persistent problem in many parts the world. Most insecurity studies focus on world's less-industrialized lower-income countries, where delivery infrastructure may never have existed. However, individuals higher-income countries experience invisible insecurity, wherein specific households or despite relative wealth their country. I...

Abstract The structural design of a mechanical temperature-driven shut-off valve used in the water and steam sampling device power plant is designed using Iventor drawing software. A NiTi shape memory alloy with high temperature-sensitivity as driven spring to control opening closing valve. In addition structures common parts valve, calculation parameter-design are also carried out. unimpeded c...

As part of the government response to the Deepwater Horizon blowout, a Well Integrity Team evaluated the geologic hazards of shutting in the Macondo Well at the seafloor and determined the conditions under which it could safely be undertaken. Of particular concern was the possibility that, under the anticipated high shut-in pressures, oil could leak out of the well casing below the seafloor. Su...
