Lodestar’s sensor package for DWD technology consists of 18 continuous recording channels measuring downhole torque, WOB, RPM, bending moment, stick slip, multi-axis vibration and temperature using high frequency record rates from 20 Hz to 100 Hz.
Measure and analyze key downhole drilling parameters
Determine actual power delivery at the bit
Evaluate and optimize BHA configurations
Evaluate and benchmark performance of downhole tools including but not limited to motors, friction reducers, stick-slip mitigators, reamers, etc.
Measure wellbore quality and tortuosity
Optimize drilling parameters to define best drilling practices
Generate, validate, and calibrate drill string behavior models
Designed and manufactured in-house, the I-SUB is an at-bit, memory-based tool which precisely records an array of parameters at a user configurable sampling rate that will best assist our customers in achieving their drilling optimization goals.
Placed behind the bit in order to provide true at-bit measurements
Ultra-compact length < 1.5 ft
Short bit-to-bend provides minimal disturbance to directional behavior
Sensor Package specified measurements
Battery Life - 15 days (360 hours)
Available sizes - 5", 6.75",8.50",and 9.6"
The short, versatile and collar-based I-STRING tool leverages the technology of our at-bit I-SUB to measure Dynamics While Drilling Perimeters anywhere in the BHA or drill string.
Flexability of placement in the BHA or in the drillstring
