LWD Full-Wave Sonic Tool
LWD
PS’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 and iPCD density data, for use in a borehole stability analysis and in the completion design of the well.

FEATURES & BENEFITS

- High-resolution data is stored in downhole memory for retrieval and processing during trips.

- Can be run in real-time MWD mode or standalone recorded data mode.

- Minimize uncertainty by tying time-based seismic data directly in with depth-based well log data.

- Full SureShot™ Control Center (SSCC™) and APSPlot™ support.

- Compatible with 3rd-party petrophysics and geophysics packages via DLIS, LAS, ASCII and WITS.

DESIGN

- Available sizes: 4.75 in. (121 mm), 6.75 in. ( 172 mm) and 8.0 in. (204 mm).

- Double-redundant (dual) 10 - 12 kHz transmitters.

- Six receivers located 6.0, 6.5, 7.0, 7.5, 8.0 and 8.5 ft from transmitters.

- Hatch cover for easy access via cable for tool programming and memory dump.
