Description

The hydrodynamic logging module allows measurements of reservoir pressure and fluid mobility together with the logging complex during drilling. Intelligent measurement mode: The sampling rate, pressure drop and pressure recovery time are optimized during the reservoir fluid suction process, which increases accuracy and reduces measurement time.

 

 Features

  • Adjustable control of the clamping force of the shoe

  • Real-time pressure measurement

  • Emergency folding of retaining pistons and shoe piston in case of loss of power

  • Compatible with all products of the company in the field of M\LWD

 

Application

  • Multiple measurements of reservoir pressure and reservoir fluid mobility during one descent of the device

  • Permeability assessment

  • Determination of fluid contacts
