... compositions occurring in the oilfield. Second, due to the complex oilfield operation conditions with large variations of water, oil and gas flow rates, tubing size, surface roughness, etc., wide ranges of flow patterns and regimes can occur in the field and need to be covered in the deposition model. Third...

... and pressure and the controlled gas flow rate running through the system which saturates the fluids with H 2 S to create a steady state ( Figure 1 ). The same concentration of H 2 S exits the system as enters. Once established this steady state is perturbed by the injection of a known volume of scavenger...

... different surfactants (Sodium dodecyl sulfate and Trifoam 820 Block) were added to the water. In the experiments, a high-speed camera was used to visualize the flow and pressure drop measurements were performed. Both surfactants increase the pressure drop at high gas flow rates and decrease the pressure...

.... From membrane filtration tests at imposed flow rate, we have firstly observed the formation of a filter-cake made of HMWSP physical gel, which remained largely permeable to polymers. This "gel-filtration" entailed modifications of the solution's viscosimetric properties, which can be explained...
