... storage moduli after fully swelling are approximately 82 Pa. The microgel characterization, self-healing process, transportation behavior, and plugging performance were investigated. A sandpack model with multi-pressure taps was utilized to assess the microgel dispersions’ transport behavior and plugging...

... summary conference sandpack spe res eval Introduction Production of viscous oil suffers from low recovery efficiencies owing to the poor mobility ratio. Increasing the amount of water injection and reducing the well spacing improves oil recovery by waterflooding from such reservoirs ( Beliveau...

..., the SAS recovery was detected only for the 7-25 case, which means 7-25 went through the sandpack whereas 7-15 did not. That is, the optimization of SAS likely requires taking a balance between lowering the partition coefficient and lowering the IFT. chemical flooding methods pvi polymer flooding...

In this study, a continuous setup was designed and constructed to investigate the deposition of nanoparticles in a sandpack that mimics the oilsand reservoirs. The VR containing...

... to analyze the in-situ gelation inferred from pressure profile and fluid production. CO 2 and N 2 gas were used as the gas phases. A heterogeneous dual-sandpack was used to demonstrate sweep efficiency improvement during CO 2 injection. Tuning the chemical concentration enabled us to optimize the gel...

... different types of emulsion flow tests were collected and analysed from previous publications, including permeability reduction of an emulsion in a specific sandpack, an emulsion slug injection followed by water injection in a specific sandpack and conformance control performance in parallel-sandpack...

... of clay-stabilized Pickering emulsion under high-salinity conditions were measured with a rheometer. Flooding experiments with clay-stabilized emulsion were conducted in both a microfluidic and a sandpack apparatus to test mobility control performance of Pickering emulsions. Results show that clay...

The viscosity was measured at shear rates ranging from 1 to 100 sec -1 . Sandpack preparation Sandpacks were put together to mimic...

... 2016 ). The majority of recent experiments performed using foams have been performed primarily in micromodels ( Telmadarreie 2016 , Conn 2014 , Lu 2017 ) or in homogeneous systems using surrogate cores or sandpacks ( Janssen 2018 , Lotfollahi 2016 , Abbaszadeh 2016 , Szlendak 2013 ), making...

.... The rheological measurements revealed that a strong droplet network forms within the emulsions over time. Importantly, we show that the same network forms when the emulsions occupy pore space in a granular material. Emulsions were injected through a sandpack with a porosity of 35% and average pore diameter of 54...

... The oil and gas injection system consists of an ISCO pump equipped with two piston cylinders in which the live oil (dead oil saturated with methane) and solvent mixture are separately storage at 2760 kPa (400 psi). During the sandpack saturation, the live oil is pumped into the top of the model...
