In the framework of a comprehensive experimental study, the erosion behaviour of filter media for sand control in well pipes was investigated. Using supplementary CFD simulations, the global technology leader for woven filter media, GKD – GEBR. KUFFERATH AG, demonstrated the relationship between inlet face velocity and distribution of pore velocities. 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 – provided the impetus for 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.
