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.
The 38mm-standard arms and 60mm-long-arm models are available to meet a wide range of diameters.
