OUR FACILITIES

Fluid analysis and

special core analysis

Centrifuge

Fourier Transform Infrared Spectrometer (FTIR)

Application

Ultracentrifuge for core samples fluid displacement tests through the action of centrifugal force. System includes full automation and data acquisition through a controlled camera and a strobe source. It is used to determine capilar pressure and wettability index (Amott and USBM)

 

Samples

Core plugs up to 1.5 inches in diameter and 2 inches in lenght

 

Equipment specifications
