Borehole Logging Mt. Sopris ABI-40 Acoustic Televiewer (ATV)

Mt. Sopris ABI-40 Acoustic Televiewer (ATV)

Item # 113012

ACOUSTIC TELEVIEWER

TOOL DESIGN PHILOSOPHY & APPLICATIONS
Acoustic Borehole scanner tools generates an image of the borehole wall by transmitting ultrasound pulses from a rotating sensor and recording the amplitude and travel time of the signals reflected at the interface between mud and formation (borehole wall). 

MOST COMMON APPLICATIONS ARE 
 Fracture detection and evaluation
 Detection of thin beds
 Determination of bedding dip
 Lithological interpretation
 Breakout analysis
 Monitoring of earth stress field
 Casing inspection
 High resolution caliper

The latest generation of ALT acoustic televiewer is a multi-echo system. This is achieved by digital recording of the reflected wave train. On line analysis of the acoustic data is made by a DSP (Digital Signal Processor). Sophisticated algorithms allow the system to detect the reflection from the acoustic window and to separate/classify all subsequent echoes. Minimum input of the operator is needed to enable:

 Automatic optimization of measurement window under all borehole conditions
 Automatic adaptation to variable borehole conditions
 Improvement of dynamic range of signal detection
 Very high travel time resolution
 Implementation of different operating mode

MAIN FEATURES 
 Direct linear 14bit, 10mhz A/D conversion (automatic gain settings)
 Dynamic range of amplitude measurement is 84 db 
 Calliper resolution is better than 0,1mm
 Orientation sensor which does not require field calibration
 Increased telemetry bandwidth (data transmission rate up to 500kbits depending on wireline), 166kbps typical on 300m four-conductors.
 Full wave form recording and real time display for quality control
 Multiecho mode to realize acoustic measurements through plastic pipes (require the plastic pipe to be centralized inside the borehole)
 Pipe-inspection mode to detect inner corrosion, outer corrosion, and wall thickness
 Automatic measurement window definition to gain optimum performance and variable borehole conditions
