Performance Drilling Advisor Service
Case Study
Fayetteville Shale Drilling Optimization
1
Background Large Independent Operator drilling multiple wells in diverse areas with rigs
of varying performance and experience.
Operator makes business decision to start a “drilling optimization” program with the goals of reducing the drilling time, reducing bit runs, delivering wells more consistently and to improve the rig’s performance, September 2008.
Operator solicits information and bids from different drilling service companies about their drilling optimization services, October – November 2008.
Operator selects the NOV IMO Wellsite Performance Drilling Advisor (WPDA) service based on the service capabilities and completeness of the service to deliver the results required, December 2008.
First deployment of WPDA service on 6 rigs, January 2009.
