A review of experimental studies on sand screen selection

2020-1-2  Sand production is a problem that affects hydrocarbon production from unconsolidated sandstone reservoirs. Several factors, such as the strength of the reservoir, its lithification and cementation and reduction in pore pressure, may cause sand to be separated from the rock and transported by hydrocarbons to the well. Producing sand commonly causes erosion and corrosion of

Classification of Alberta Oil Sands Based on Particle Size

2017-2-15  The method which is introduced for oil sand classification is based on the D-values which are commonly used in screen aperture design. This method provides a useful tool for both screen designers and researchers to categorize and focus their work on a specific set of representative PSDs, rather than a wide distribution of PSDs.

Sand Classifying Tanks McLanahan

Popular Applications for Sand Classifying Tanks. Sand Manager™ Classifying Tanks are capable of making one or two products for most construction sand specifications and one non-spec product at any one time. To make different products, the tank is designed with two or three valves at each station along the length of the tank, one more valve than the number of spec products desired.
