[Casing Colar Locator Tool]
Scope of Applicability
- Depth Matching between cased-hole logs and well schematic based on location of tubing/casing collars
- Locating the bottom of tubing
- Locating the current bottom hole
- Locating the perforation intervals
- Locating the casing or tubing deformation
Mathematical Model
There are two modification sof the tool: passive and active
CCL Passive
CCL = k \cdot H \cdot LSPD |
CCL Active
CCL = k H |
