Desert sand is one of the current research hotspots in alternative materials for concrete aggregates. In the process of practical application, compressive strength is an essential prerequisite for studying other properties. Based on the current research situation, a prediction technology of compressive strength of desert sand concrete (DSC) is proposed based on an artificial neural …

Sand deposition can also occur in the lower completion below the ESP. In both cases, a flow-stabilized sand dune is created and, upon ESP shutdown, the sand may plug the well, either above or below the ESP. To eliminate this risk, a check valve is run above the ESP to prevent flowback into the pump during shutdowns.

Sand is one of the ultimate stages in the disintegration of rocks. In deserts, the principal agent of erosion and the transport of materials is the wind (wind erosion). If the wind can act so effectively in eroding and in the transporting of particles, it is because there is neither humidity nor vegetation nor relief to hold and stabiilze those particles.
