Operator Drills Back-to-Back Record-Setting Curves in Delaware Basin

Overview

An operator drilling in the Delaware Basin completed their fastest curve section in the area, having collaborated with the Halliburton Sperry Drilling team to optimize the drilling program. It was decided to drill this well section utilizing the 4.75-in. iCruise^® intelligent rotary steerable system (RSS), matched with a 6.75-in. GeoTech^® GTi64D drill bit. 

Multiple technologies were combined to improve drilling performance over offset wells in the region: 

• The equilibrium, force, and critical speed modules of DrillingXpert™ well engineering software were used for modeling bottomhole assembly (BHA) design to meet the steering objectives, while balancing side forces across the BHA and identifying the optimum operating window to minimize vibration.
• The custom drill bit was designed using our industry-unique Design at the Customer Interface (DatCI℠) service, which helped improve bit design from well to well based on downhole data.
• The ADT^® (Applied Drilling Technology) drilling optimization service provided real-time drilling performance optimization and vibration mitigation.
