... At the beginning of the experiment, the viscosity of SURF-based foam (5 vol/vol%) reached 37 cP at 275 °F and then decreased with time to 26-22 cP at temperatures of 300-350 °F, respectively. We believe that the increase in liquid drainage and the coalescence of the bubbles with increasing...

... with moderately-low viscosity should be injected into offshore reservoirs to keep displacing pressure between injectors and producers. The injected polymers should have good transportation ability which avoids the formation blockage. The optimum injection timing remains to be further investigated because...

Rheological properties, such as viscosity and yield stress, were measured for hydrate slurries in crude oil for under-inhibited systems with two different thermodynamic hydrate inhibitors (THI...

... itself. The viscosity increase due to emulsion formation severely hampers the ESP performance, requiring an increase in energy consumption on the platform to keep the same production rate. This work presents an initial validation of the model proposed by Bulgarelli (2021) to predict the water-in-oil...

... and numerous other polymers have historically been used to accomplish this function, albeit with limitations. Functionally, these commonly used polymers depend primarily upon viscosity rather than elastic characteristics to suspend solids and require intensive chemical processing that leads to high deployment...

... Abstract The detection of asphaltene precipitation and gas hydrate formation is critical to preventing production losses and to optimize strategies for mitigation and remediation. Likewise, the evaluation of some flow properties (e.g., viscosity and yield stress) of the slurries formed...

... combination and using a cup-and-bob geometry. Steady shear viscosity was measured at 100 s -1 . A set of varying shear rates was applied at each temperature to obtain the rheology profile. The shear rates in the set were defined as follows: 600, 500, 300, 200, 100, 75, 25, and 10 s -1 . Viscosity versus shear...

... Two major challenges in CO 2 enhanced oil recovery (EOR) are the high mobility of CO 2 and reservoir heterogeneity. High CO 2 mobility, related to the low density and viscosity of CO 2 , compared to in-situ fluids can cause viscous fingering, gravity override, and flow in thief zones...
