SLIM GEOPHYSICAL LOGGING

INTRODUCING OUR NEW SERVICES!

 HRAT - High Resolution Acoustic Televiewer

HRAT is the most modern acoustic image equipment, providing high-resolution oriented images concerning to the walls of the well.
 

Applications include:


• Identification of fracture and orientation.
• Stratigraphic studies.
• Stress Studies.
• Hole orientation.
 

Further information can be obtained from this short presentation.

 

 

Caliper and Gamma Slim Rays (Three-Arm Caliper Probe)
 
The three arms of mechanical coupling in contact with the well walls provide a continuous record of the well diameter.
The 38mm-standard arms and 60mm-long-arm models are available to meet a wide range of diameters.
