Wireline Drilling
- Faster drilling cycles: Core is retrieved without tripping the rods, cutting non-productive time.
- Deep-hole capability: Efficient and economical for deep drilling where conventional coring becomes slow.
- High core quality: Good recovery and well-preserved samples for logging, assay, and testing.
- Borehole stability: Rods act as temporary casing, protecting the hole in difficult formations.
- Lower labor and wear: Less handling of rods reduces operator effort and equipment wear.
