Logging while drilling (LWD) technology can useful geological information with the following advantages:
- Near-bit, therefore hopefully best available borehole conditions
- Less time required for tools on-site, hence possible savings
LWD image resolution and quality can be high depending on tool choice and conditions.
As with all tool types, even similar imaging technologies developed by different companies can have important differences. Correct circumferential positioning in particular is vital to ensure that any feature orientations derived from the image are as accurate as possible.
Task Fronterra has a wealth of experience both in loading the various types of LWD image data and in their interpretation, from 4-sector density to the latest 120-sector resistivity images.
