MWD data acquisition & logging — guides
Short, practical notes on getting MWD data from the surface system to a finished log.
What is MWD data acquisition? A practical guide
MWD data acquisition is the surface software that decodes, records and displays measurement-while-drilling data in real time. Here is what it captures and why it matters.
Choosing MWD logging software: a practical checklist
A field-tested checklist for evaluating MWD logging and data-acquisition software: connectivity, survey corrections, azimuthal GR, memory processing, LAS export and licensing.
Reading azimuthal gamma-ray images for geosteering
How the azimuthal gamma-ray image is built from borehole sectors, how the unwrapped view is oriented, and how to read the sinusoid to geosteer and find dip azimuth.
WITS Level-0 explained for MWD surface systems
WITS Level-0 is the simple ASCII format that carries rig and MWD data between systems. Here is how the format works, serial vs TCP, and how items map to channels.
