Description
The “Pneumatic Flashlight” and Drilling Dynamics Recorder (DDR) system is a fully retrievable measurement and gamma logging while drilling system and electronic drilling recorder.
The system is meant to integrate with conventional Reverse Circulation drilling rigs.
The up-hole and down-hole tools allow real-time data transmission of gamma ray and wellbore trajectory.
On the surface, drilling parameters that are monitored include depth, torque and weight on bit, which are sent to the office in real time via cellular network.
The system allows real-time mapping of ore bodies and drilling optimisation.

Applications
- Delineation of ore bodies.
- Real-time drilling monitor.
- Drilling Optimization.

Features & Benefits
- Retrievable RC downhole tool.
- Real-time delineation of Ore bodies.
- Real-time drilling performance monitor.
- Reduced personnel on site.
- All data recorded in memory.
- Wireless link from downhole tool to surface.
- Air hammer performance monitor.
- Standardise measurement across rig types.
- Expandable Architecture.
