Emphasis on Wellbore Quality Troy Oney

Defining “Wellbore Quality” “A high-quality wellbore is generally considered to have (1) a gauge hole, (2) a smooth wellbore wall, and (3) a wellbore with minimum tortuosity.” Chen, Gaynor, Comeaux, & Glass, 2002

Drilling Equipment Rig based offerings to address Wellbore Quality

FlexB2D™ WHAT IS FlexB2D? Back to Drilling is a set of processes designed to engage the bit, resulting in improved bit life and repeatable performance providing the following benefits. LONG TERM BENEFITS OF USING FlexB2D Proper and consistent bit engagement after a connection Automated zeroing (WOB and Delta-P) to ensure accurate and consistent process Reduced torsional and lateral vibration to bit and BHA components Automated staging to drilling setpoints after tagging bottom, accounting for drilling dysfunctions Reduced unplanned trips, by potentially extending bit life Decreased transition time from connection to drilling 9 Operator defined setpoints ensure consist execution
