Full Previous HitWaveNext Hit Acoustic Logging: Some Examples

John W. Minear


More information about formation properties than is commonly utilized is available in the acoustic signal. The objective of full-Previous HitwaveNext Hit acoustic logging is to use more of this information to determine formation properties.

Full-Previous HitwaveNext Hit acoustic tools generally have transmitter-to-receiver spacings greater than about eight feet. This provides deeper penetration and facilitates signal analysis. Full-Previous HitwaveNext Hit acoustic signals are briefly discussed.

Shear Previous HitwaveTop slowness, or Δts, is one of the most important new acoustic logging measurements. Used with Δtp, Δts provides basic log quantities for lithology identification, gas zone identification, estimation of lithology and porosity with acoustic logs only, and improved formation elastic property estimation.
