Utility of Rig Data Capture System For Key Energy  Rig Operator: Provides visibility & feedback for rod & tubing makeup Quantifies implementation of work plan Reduces risk of crown out & floor out & other safety events  Rig Supervisor: Allows for monitoring from any PC Provides tool for in-depth process improvement For Customer  Assurance  Ability to improve wellwork processes company-wide

Improvement Examples Quality Improvement: Sucker Rod Makeup  Problem: Rod string failure rate increased from 0.3 failures / year to 2 failures / year After 3 pin failures production engineer decided to lay down rod string  Solution: Rig with data capture system moved on well to lay down bad rod string Rig make up / breakout monitoring system found every 3 rd joint over- torqued; previous rig over torqued rods  Savings: Company spent $46k on 3 well pulls & rod string replacement $46k avoidable if rig data capture system utilized

Improvement Examples Quality Improvement: Sucker Rod Makeup  Problem: Rod string failure rate increased from 0.3 failures / year to 2 failures / year After 3 pin failures production engineer decided to lay down rod string  Solution: Rig with makeup control moved on well to lay down bad rod string Rig data capture system found every 3 rd joint over-torqued w/ breakout monitoring; previous rig over torqued rods  Savings: Company spent $46k on 3 well pulls & rod string replacement $46k avoidable if rod makeup control utilized

Improvement Examples Efficiency Improvement: Non-Productive Time  Problem: 40 rig operation where customer had increasing job times but no accurate data from which to base decisions  Solution: Rig data capture identified wait time problem & cause by rig Operator & service providers analyzed data & implemented corrective actions Over following 10 months wait time reduced from 12% of rig time to 6%  Savings: $14.20 per rig hour $1.10 million in reduced annual rig expense Additional operating expense savings from additional services on location; $0.15 million

Improvement Examples Efficiency Improvement: Non-Productive Time  Problem: 40 rig operation for customer had extensive wait time but no accurate data from which to base decisions  Solution: Rig data capture identified reasons for wait time by rig Operator & service providers analyzed data & implemented corrective actions Over following 10 months wait time reduced from 12% of rig time to 6%  Savings: $14.20 per rig hour $1.10 million in reduced annual rig expense Additional operating expense savings from additional services on location; $0.15 million

Where does WITSML Fit in? We’re new to the game – but there’s a lot of opportunity for the well servicing industry We’ll go beyond just the “drillsite to office” use Embrace the standard  Work with the SIG to gradually grow the standard to incorporate workover & well servicing needs Customer Integration  Current prototype project with a large customer to “WITSML-ize” Keyview information in the form of a tour sheet, to the extent possible Standard format for Archiving & Retrieval

Leverage off of the similarities WellLog/Log Object OpsReport Object Well Object Message Object None are well-servicing specific, but there is a considerable amount of similarity

Along the path to “WITSML-ization” The current WITSML is drilling-specific – Is this standard an appropriate one to use for intervention work (R&M, workover, etc)? “Standard” activities list – the current WITSML catalog supports 20 IADC activities. Are more, with greater detail, needed? WITSML must be more than just “Transfer” – will it be appropriate to use WITSML as a set of standardized systems interfaces?

The Future System that is:  A source of collaboration & performance measurement for operators, well servicing companies & all third parties (WITSML)  A pipeline for electronic data from any service provider on location to the customer (WITSML)  A source of process data from which to perform continuous process improvement (WITSML?)  Is a foundation for other digital technologies utilized during well work operations (WITSML)
