Description
The patented Flashlight tool allows the continuous measurement of inclination, azimuth, gamma and azimuthal gamma at the bit. It is a short sub that is placed between the motor and the bit placing sensor inches away from the bottom of the hole. A receiver sub and probe sits in the MWD string and receive data via wireless signal from the at bit sub. Data is then passed to the MWD and telemetered to surface. With the design of the receiver and receiver sub it allows the MWD to be fully retrievable.
The at bit sub can send up real time 50 different variable including status words on health of the tool to compressed azimuthal gamma for faster update times.
Our proprietary manufactured directional sensors and gamma probes provide better control over quality and performance. With our high torque receiver sub we can now achieve unprecedented reliability.
Applications
- Geo Steering.
- Casing point selection from at bit measurement.
- Steering in formation with dipping beds.
Features & Benefits
- Bit to sensor is one feet.
- Reduced doglegs.
- Optimized well placement.
- Adapts to any motor type.
- Signal strength measurement.
- Tri axle accelerometer/magnetometers
- Continuous at bit inclination measurement.
- Vibration at bit measurements.
- Temperature at bit measurement.
- Works in oil and water based muds.
- All information is real time and memory recorded.
- EM short hop.
- Calibrated and operates up to 175°C.
- Dual Battery for longer bit runs.
- Increased the dynamic range of the rotatory inclination sensor. This enables it to read more accurately at lower inclinations and more resilient to bad reading from shock and vibration.
- Waning flags to verify tool health and what the rotary algorithm is doing. It acts as a qualifier to tell if the data being sent up hole is good.
- High torque (XT Connection) increases the reliability of the receiver gap sub.
