New woven filter mesh for more throughput at lower local pore velocities

The erosion behaviour of filter media for sand control in well pipes was investigated in the framework of a comprehensive experimental study. As global technology leader for woven filter media, GKD demonstrated the relationship between inlet face velocity and distribution of pore velocities by using supplementary CFD simulations. The insights gained through this computer modelling – that through higher volume porosity of the deployed filter media the local flow velocity in the mesh pore can be reduced – prompted GKD to develop a completely new mesh filter: Porometric mesh. The outcome is a very open three-dimensional mesh construction that, while maintaining a constant volume flow rate, further reduces local pore velocity by up to 40%, with throughput increasing by a similar factor. Properties like these represent unprecedented advantages for efficient oil and gas exploration.
