How the HTHP Filter Press Works

The device operates using API-recommended procedures where temperature and pressure are finely controlled to simulate downhole filtration conditions.

During testing:

The mud sample is placed into the cup.
Pressure is gradually applied using Nitrogen or CO₂.
The heating jacket raises the temperature to desired levels.
Filtrate passes through the filter paper.
The filtrate volume and mud cake thickness are measured.

This process delivers dependable data critical for evaluating drilling fluid stability, rheology, and filtration behavior.
