How the HTHP Filter Press 175 ml Works

The filtration process follows API-recommended procedures to ensure standardization and accuracy. The HTHP Filter Press 175 ml applies controlled temperature and pressure to simulate downhole conditions. During testing:

  1. Temperature is raised up to 232 °C

  2. Pressure is applied up to 4.2 MPa

  3. Filtrate passes through the filter medium

  4. Mud cake thickness and fluid loss are measured

This method provides valuable data on drilling fluid stability, performance, and wellbore protection capabilities.

Major Components

The equipment is supplied with essential high-quality components, including:
  • Principal machine assembly
  • Mud sample cup
