High-Frequency Torsional Oscillation Recorders
High-Frequency Torsional Oscillation Recorders
CuBIC® HF, from Sanvean Technologies, is the industry’s first high-frequency embedded drilling dynamics data recorder capable of continuously logging 3-axis +/-200G vibration data at 800Hz & 1600Hz. The compact design allows the sensor to be embedded at any point within the BHA and drill bit, providing continuous high-frequency measurements in existing BHA components without adding additional carrier subs. CuBIC HF sensors can also be used to measure High-Frequency Torsional Oscillations (HFTO). Identifying HFTO frequency and magnitude within the BHA is becoming a critical component of successful and reliable BHA design.
Features:
- High-Frequency continuous measurements
- Compact and rugged design
- 3-Axis lateral, axial, and torsional vibration measurements
- Provides at-point measurements at the points-of-interest within the BHA and bit (i.e. at-bit and above motor power section) in all hole sizes (including slim-hole)
- Mounted on the outside diameter of equipment to measure actual accelerations that can influence drilling efficiency and equipment damages
- Simple and easy-to-read data output allows for quick decisions on drilling parameters and BHA changes
Benefits:
- No additional BHA length or BHA connections. No risk of fluid erosion
- Embedded into existing BHA tools and bits
- No field personnel required (automatic trigger on/off with RPM on/off)
- Allows comparison of BHA and third-party HFTO reduction tools to evaluate magnitude reduction of HFTO
- Fast memory download for rapid turn-around times
- Can also be used in conjunction with rock property analysis
