Intelligent Waveform Sonic Tool (iWS)

Download Spec Sheet

The iWS acoustic tool was designed for acquiring high-resolution, full-wave acoustic data. The tool features a monopole transmitter and a five-receiver array, which records waveforms at each receiver, while obtaining formation-integral travel time (Δt) and shear (Δt) in fast formations. The iWS requires a fluid-filled borehole and can be used in fresh, salt or oil-based mud systems. In cased holes a traditional cement bond log can be produced.

LOGGING APPLICATIONS:

  • Compression and shear velocity measurement
  • Determine mechanical characteristics of formation
  • Correlate seismic data
  • Secondary porosity measurements (vugs, fractures)
  • Determination of lithology
  • Casing cement evaluation
