LWD Full-Wave Sonic Tool

Lower cost by replacing wireline logging

LWD Full-Wave Sonic Tool

APS’s Full-Wave Sonic Tool is a formation slowness measurement tool designed for wireline-equivalent logging while drilling (LWD) and measurements after drilling (MAD) services. This full-waveform sonic device adds Δt (delta T) measurements to the “Triple Combo” LWD system, providing faster-than-fluid compressional wave (Δtc) and shear wave (Δts) velocity data.

Geophysicists can use Sonic sensor data to minimize uncertainty by tying time-based seismic data directly in with depth-based well log data. The rock’s mechanical properties can also be calculated using APS Sonic density data, for use in a borehole stability analysis and in the completion design of the well.
