- Locate casing collars in highly deviated wellbore to set bridge plug
- Improve milling and overall efficiency in a whipstock casing-exit operation
- Reduced number of trips necessary to locate all casing collars
- Improved reliability and reduced operational risks
- Set bridge plug accurately and performed successfully casing-exit operation
On a casing exit operation in the Gulf of Mexico, a customer needed to perform a casing collar locator (CCL) run prior to setting a bridge plug in 11 3⁄4-in., 65 lb casing. Typically, this kind of operation is done using wireline, but because the wellbore was highly deviated (approximately 70°), wireline was not an option. With this challenge, an extra trip down to 8,500 ft (2590 m) would be necessary, incurring additional rig time and costs.
