ABSTRACT:
A bore hold hydraulics simulator for drilling fluid is disclosed, in which the drilling fluid is flowed along a permeable partition which divides a first volume containing the drilling fluid from a second volume adapted to collect filtrate passing through the permeable partition. A pressure differential is established across the partition so as to promote the passage of filtrate into the second volume, and a vessel is provided for collecting the filtrate passing into the second volume.
