1 DYNAMICS WHILE DRILLING

2 DYNAMICS WHILE DRILLING The Lodestar suite of dynamics while drilling (DWD) tools allows customers to obtain the downhole data that enables them to create the most efficient and cost effective drilling program. Through our partnership with MaxWell Downhole Technology, a global leader in downhole measurement technology, Lodestar has now added the I-SUB, I-STRING, and I-SURFACE to its DWD portfolio. These tools allow Lodestar to offer its customers a complete suite of DWD tools that are a fit for any job or drilling project. Lodestar s DWD suite of tools allows customers to measure: Shock Vibration Stick Slip Downhole WOB Downhole Torque Downhole Bending Moment Downhole RPM Continuous data record rates up to 100Hz

3 APPLICATIONS Measure and analyze key downhole drilling parameters Evaluate BHA configurations Determine actual power delivery at the bit Evaluate downhole motor and other tool performance Model downhole drillstring behavior Define best drilling practices I-SUB Ultra compact, < 1.5 in BHA Available for hole sizes from 6 to 17.5 Provides at bit measurements Record rates from 20 to 100 Hz Up to 360 hours of recording time (20 Hz) Total acceleration field: AccX, AccY, AccZ, Rotational Total forces and stress field: WOB, TOB, Bending, RPM I-STRING Provides DWD measurements anywhere in the drillstring Includes all I-SUB capabilities and sensors Available for hole sizes from 6 to 17.5 Record rates from 20 to 100 Hz I-SURFACE Provides DWD measurements at surface Includes all I-SUB capabilities and sensors Record rates from 20 to 100 Hz Match high resolution downhole data with high resolution surface data Measure drill string mechanics with sensors attached to the string

4 Suggested DWD Program Potential Sensor Placement I-SURFACE I-STRING Located Throughout Drillstring Continuity of measurements along entire drill string Evaluate performance of friction reduction tools Determine locations of buckling Identify high torque loss areas or components Pinpoint drilling dysfunction I-SUB Located at the Bit The Lodestar suite of DWD tools is the perfect solution for ensuring that your drilling program is constantly improving. Use the I-SUB in conjunction with the I-STRING and I-SURFACE for the most comprehensive analysis of drilling parameters.
