In all advanced rock property tests, sample geometry is of critical importance in
the providing accurate and representative data from core samples. Fluid flow models
are based on algorithms that require a specific geometry to validate their assumptions.
In our production laboratories strict sample quality criteria are in place that
ensure the highest possible conformance to a right, circular cylinder with flat
parallel endfaces. Continuous sample/end piece contact is mandatory for capillary
pressure, electrical property and relative permeability tests. In acoustical testing
perfect transducer/sample contact in critical for accurate data to be determined
and in pore volume determinations small gaps between endpieces and sample are included
in the pore volume.
The precision bench top Endface Grinder is supplied complete with precision machined
V-block sample holder for 1 inch and 1.5 inch diameter samples. An optional wheel
coolant lubricating system is available to remove “rock flour” from the sample during
