Simulation of Interferometric Seismoelectric Green’s Function Recovery: For the SH-TE propagation mode

A recent novel technique known as seismic interferometry makes use of seismic ‘noise’ to reconstruct a Green’s function between two receivers by crosscorrelation. This technique can be applied for example in permanent subsurface monitoring using passive seismics or the creation of virtual sources on positions where only recordings were made. The...

Finite Element Analysis of Cahn-Hilliard equations: Mass transfer of an oil-soluble chemical for water control

Two models have been constructed and physically motivated based on the (system of) Cahn-Hilliard equation(s) and Stefan problem in order to describe the behavior of fluids in a hypothetical mixture. A finite element method is developed to solve the Cahn-Hilliard equations based on a mixed formulation where reduction of the forthorder spatial...

Dealing with clay when mining diamonds offshore: High rate mining tool development

De Beers Marine is currently mining diamonds offshore near the Namibian coast (at water depths of 115 - 140 meters), using a vertical batch drill mining system ('Wirth drill"). Previously also continuous seabed crawlers have been used, but this method was discontinued because of unsatisfactory operational performance and recovery of the diamonds...
