Overview
Need of new tools to compensate commercial tools for steel well finding that are easy-to-use and lack of available borehole finding tools for non-ferrous and non-metallic wells.
Objective
LBNL is developing a drone based well identification tools using active source EM technology. It is aimed to offer an alternative to commercial magnetic tool with the following advantages:
- New sensing modality for non-metallic wells
- Easier to use/interpret
- Sensitive to non-ferrous materials
- More accurate location
- Less sensitive to cultural noises
Short Term Impact:
Offers a new well identification tool to improve identification accuracy and reduce uncertainty.
Long term impact:
A scalable approach that can be easily adopted by stakeholders for undocumented well identification.
Accomplishments
- Acquired and demonstrated baseline hardware for tool development.
- Identified key performance metrics and developing numerical simulations to aid equipment design.
