Given the general use of circular pipes in the oil and gas industry, circular waveguides are part of the MDMA, but it can be applied to any shape of closed conduit. Figure 1 , shows its latest design From the theory of circular waveguides, the transverse electric (TE...

... Moreover, several studies have been conducted on the effects of LSP floods on the geochemical interactions between the rock-brine interfaces and the effects on polymer viscosity. Unsal et al. (2018) reported on the influence of LSP in increasing polymer injectivity whilst decreasing retention...

Phase behaviours (volume of oleic and aqueous phases) were tracked over time for two months using a mixture of 50% aqueous solution (either brine, polymer brine or alkali...

... in Figure 3 . Then valve V8, which is connected to brine/oil is opened slightly to remove any air within the pipe that is connected to the pump. Similarly, the seventh pump is filled with overburden fluid (glycol-water 50/50 by volume). To set up the system completely, first, we need to calculate dead...

... ratios. In addition, water swellable elastomers are not suitable for applications which have a high salinity brine or produced water as the setting fluid. By contrast the expanding metal alloy chemical reaction is enhanced by increasing salinity. The expanding metal alloy bonds with the water-based...

... polymer, acrylamido tertiobutyl sulfonate (ATBS), was used as the profile modification agent and prepared in 200,000 ppm salinity brine. The rheological behavior of the polymer was studied at 70°C at various concentrations. Also, a set of single-phase flooding experiments was performed using coreflooding...

The effects of salinity and temperature on swelling, swelling rate, and rheological behavior was studied. These HT-PPGs exhibit excellent...

... Gravel Packing (OHGP) with or without shunted screen technology is a common completion technique. Prior to this paper, there has been no application of shunted screen OHGP in High-Pressure High-Temperature (HPHT) environment due to lack of a viscous fluid availability in high-density divalent brines...
