Paper Number: SPE-192218-MS
... used two very different driving mechanisms for the fluid displacement: centrifuge and flow-through. The data showed that carbonate and clastic rocks behaved differently over a wide range of flow mechanisms and water saturations, proving that mineralogy plays a crucial role in the fluid displacement...

... and understand the responsible mechanisms at scales ranging from nano-scale to field scale. The ionic formulation of the injected brine affects dramatically the crude oil/brine/rock interfaces, altering rock wettability and improving oil recovery efficiency. In this experimental work, a mechanistic study...

... of this mechanism is the dip in the surface that happen when the yield stress is diffused between the two fluids. This shows that, for a particular angle, size of hole and density contrast, the amount of yield stress needed for stability when just one fluid has a yield stress is more than the addition of the two...

... Abstract Disproportionate Permeability Reduction (DPR) is often used as a water-shutoff treatment in production wells when conventional solutions such as mechanical isolations are difficult to perform. Although this property has been well documented by different investigators, the performance...

.... The aggregation behavior and thickening mechanism of both molecular categories is analyzed by SEM intuitively. Emulsification performances are investigated by analyzing the kinetic stability and rheological rules. Finally, displacement efficiency of the two categories is achieved by core flooding. Experimental...

Understanding the corrosion and scaling mechanism under downhole conditions is very important in order to develop effective prevention and mitigation strategies in a timely manner. An advanced downhole corrosion and scale monitoring (DCSM) tool has been designed and developed...
