| DYNAMIC HPHT? Filtration System - Model 90 |
The industry’s only true dynamic filtration system for conducting filter cake formation and permeability analysis for drilling fluids optimization
Utilizing a wide range of available filter mediums, the DYNAMIC HPHT filtration system can be heated and pressurized to provide the closest possible simulation of down-hole conditions. Several safety features have been designed into the system to protect the user and help ensure reliable test results.
The filter medium is a thick-walled cylinder with rock-like characteristics to simulate the build-up of filter cake on the formation. The filter medium is available in varying porosities and permeabilities to simulate down hole formations.
Filtration occurs radially from the inside of the filter core to the outside. At the same time, the filter cake is formed on the inside of the filter core to simulate filter cake formation on the wall of a borehole. Following completion of a test, the filter cake can be inspected visually. A polished stainless steel shear bob runs through the central axis of the filter core. The shear bob is rotated to produce a concentric cylinder-type shear across the filtration surface.
The LCD display allows monitoring of real-time test results, which are printed for further analysis and filing of test results. The DYNAMIC HPHT filtration system also features an interface port, which allows downloading of ASCII-formatted data to a personal computer. The system is fully automatic with a built-in computer controller.
Through menu-driven software, the user can establish up to 20 sequence steps to program the following testing parameters:
-
Temperature
-
Pressure
-
Differential pressure
-
Shear rate

The Dynamic High-Temperature High-Pressure (HTHP) filter press measures filtration properties under varying dynamic downhole conditions. A motor-driven shaft fitted with propellers turns at varying speeds inside a standard 500 mL HTHP cell. RPM settings from 1 to 1600 RPM impart laminar or turbulent flow to the fluid inside the cell. By varying the shaft length, the shear stress may be increased or decreased. Power is driven to the stirring shaft by a timing belt that is easily accessible for quick adjustment and removal. Other features include a variable-speed motor controlled through an SCR controller. RPM is indicated on a digital tachometer. The test procedure is exactly the same as that in the standard HTHP filtration test. The only difference is the fluid circulates inside the cell while filtrate is being collected. Since the filter medium is conventional disk material, the results are comparable with those of other laboratories or for comparing historical trends.

HTHP Dynamic filtration testing determines if fluid is properly conditioned to drill through permeable formations. Test results include two numbers: the dynamic filtration rate and the cake deposition index (CDI). The dynamic filtration rate is calculated from the slope of the curve of volume versus time. The CDI is calculated from the slope of the curve of volume/time versus time.
