Paper presented at the SPE Annual Technical Conference and Exhibition, October 16–18, 2023
Paper Number: SPE-215059-MS
... Likewise, in this study, we intended to capture the associated physics of the LSP injection process and its implications on polymer rheology (i.e., viscosity). Therefore, to achieve this, the inaccessible pore volume (IPV), polymer adsorption, Todd-Longstaff mixing model parameters, permeability...

... if residual oil is present. Similarly, Alfazazi et al. (2021 ) found that an ATBS-acrylamide copolymer at 50°C in Indiana limestone showed an unexpected rheology shift with versus without residual oil present. Also, Masalmeh et al. (2019 ) found that an ATBS polymer at 50°C in reservoir carbonate cores...

Paper Number: SPE-215083-MS
... Abstract Induced fractures often play a key role in achieving acceptable injectivity during polymer floods, especially for vertical injection wells. However, fracture extension must be controlled to prevent severe channeling between the wells and compromise the flood performance. This paper...

.... The rheometer was equipped with a temperature-controlled Peltier assembly to measure the viscosities of the polymer and Silica nanoparticle-assisted polymer nanofluids at the desired temperature. The cub and bob assembly is used as the viscosity-measuring hardware configuration. The polymeric solution...

.... However, the loss of polymers from the flow back fluid has been observed in the recent fracturing application. Those polymers are very likely to reside in the near wellbore areas, especially in the matrix, minor fractures and intersection between matrix and fractures, which leads to the reduction...
