Description

The 2SAA-1000-F Modular Full Waveform Sonic tool is used extensively in the groundwater, mining, and geotechnical industries. Sonic logs are widely employed, often in combination with other logs, to provide porosity, permeability, and geo-mechanical properties. This probe is ideal for cased-hole and open-hole applications, such as fracture identification and cement bond logging. Sonic probes must be used in fluid filled holes.

Several features of the 2SAA-1000-F sonic probe set it apart from conventional probes.  The tool is modular, which allows the user to connect various sections together to form the specific tool needed.  It is a variable frequency tool that can be used for surveys in many different environments and can be configured in the monopole or dipole mode of operation.

The receivers can also stack and average multiple waveforms to cancel noise when the received signal amplitude is low. Compressional wave velocity, shear wave velocity, Stoneley wave velocity, and Stoneley wave amplitude can be easily measured in real time in almost any situation. The 2SAA-1000-F is a standalone tool.

Applications

  • Cased hole: Cement Bond Logging (CBL)
  • Porosity and permeability evaluation
  • Lithology identification
  • Variation of rock strength
  • Calculation of rock mechanical properties: Elastic moduli, Poisson’s ratio, Shear modulus, Young’s modulus, Bulk modulus and compressibility
  • Identification and hydraulic characterization of fractures
