Fluid and rock properties Cabinet
Cabinet activity
The cabinet is used for regular rock (core) analyses (effective porosity measured by helium injection, absolute i.e. Klinkenberg permeability by injection of nitrogen through the core at simulated overburden pressure in Hassler core holder, heat conductivity) and special core analysis for fluid saturation estimates and pore size distribution estimates (capillary pressure based on Purcell’s method) for properties which cannot be expressed using the Darcy’s equation. The cabinet has access to the equipment for the fi eld tests such as fl ow rate measurement in pipes and pipe thickness and heat conductivity measurements by thermal response test (TRT) by circulation of heated fl uid through the underground loop.

Porous Plate Capillary Pressure Apparatus
|
The assembly includes measuring cell with ceramic plate, console with valves and gas pressure regulators and a precision manometer. Working pressure range 0-5 bar.
|
Experimental capillary pressure data are further used in evaluation of fluids saturation distribution in the reservoir. Note: the instrument can be used only for student demomstration purposes.

|
Relative Permeability Apparatus
|
The experimental device consists of a hydrostatic core holder, motorized piston volumetric pumps, valves, regulators and manometers for inlet fluid pressure and load petrostatics sample.
|
Measured relative permeability data are used in conjuction with capillary pressure data to calculate fractional fluid flow rates in the reservoir as well as at a production well.
