The DrillRdillo Drilling Scraper is a 360° contact robust scraper tool with retracted scraper blades which can be activated when desired through ball drop. It is designed to be run in a drilling string in a switched-off mode while drilling open holes section. When wanted the blades are activated to allow scraping of the casing.
Features
- 12 robust scraper blades arranged to provide 360° coverage of the casing wall
- Blades are retracted within the body to prevent damage or sticking during drilling operations
- When required a simple and reliable ball drop is used to activate the blades
- Single piece body made from high strength steel
- Carbide faced ribs for robustness
Benefits
- Cost savings
- Eliminates the need for a dedicated scraper run
- Increases Well Productivity
- Reduces time between drilling to target depth and running completions
- Integrity
- Mitigates premature lower completion failure
Applications
- Scraping the liner hanger / lower completion packer setting depth in same run as hole section drill out
- Unstable open hole formations where time to land lower completion is critical
Operational
- Space out the DrillRdillo™ Drilling Scraper at maximum depth inside the casing when the bit will be at planned TD
- Drill the open hole section as planned
- Once drilling is complete, drop the activation ball to activate the scraper blades
- Scrape the critical areas by reciprocating the pipe. Rotation is advantageous but not necessary due to the 360° design of the tool
