Industry Issues Faced by Operators
Real-Time DRMS for Operators
Wellhead & Conductor Integrity
•Wellhead and conductor system subjected to cyclic lateral loads from drilling riser and vessel motions driven by environmental conditions
•Fatigue damage generally accumulates in “fatigue hotspots”
Implications
•Not having real-time data on fatigue life consumption to allow proactive actions to be taken can lead to allowable damage being used up too quickly thus causing well abandonment and loss of CAPEX
Operating Windows
•Drilling operations confined by critical parameters such as Flex Joint Angles, Telescopic Joint Stroke, Tension, & BOP Motion
•Without real-time data proactive measures cannot be taken
Implications
•When operating windows are exceeded this causes uncertainties regarding asset integrity bringing a greater likelihood of operational HSE issues and Non-Profitable Time
Extreme Weather Events
•Environmental conditions can slow or halt operations due to uncertainty of effects on equipment
•Loop Currents have been a major cause of concern for our clients
Implications
•Lack of real time data and/or KPI traffic light system from a DRMS leads to major Non-Profitable Time (NPT) and Invisible Lost Time (ILT) thus diminishing shareholder value and ROI

Situation Awareness through Real-Time Data and KPI’s
Real-Time DRMS for Operators
Real-Time Instrumentation Data Feed
• Allows an overall view of the system structural response
• Allows trends and anomalies to be visualized
• Data is stored and can be transmitted to base
Real-Time KPI’s
• Pre-analysis of well, vessel, and equipment performance specifications are fed into software to enable customized traffic light KPI indicators
• Rig crew can easily know when something is wrong and proper risk mitigation measures can be taken

Increasing ROI by Reducing Non-Profitable Time (NPT)
Real-Time DRMS for Operators
Deepwater Well Costs vs. Real-Time DRMS
•Average deepwater rig costs are $500k/day*
•Real-Time DRMS have a per rig annualized cost of $400k – $1 million per year to operate depending on complexity.
•Typical payback for the DRMS is achieved by saving as few as 1 day of rig time.
Case Study
•Client without a real-time DRMS came to us in the midst of high loop current events in which they shut down rig ops and needed measured wellhead fatigue data to resume operations or disconnect.
•We were only able to instrument the Telescopic Joint (TJ) and could not deploy sensors subsea to gather measured BOP motion data due to the high currents.
•The rig had 10+ days of NPT due to relying on overly conservative analysis prior to our arrival. Actual time saved was 4 days after analysis of our measured TJ data.
•If the Client had a real-time DRMS they could have known the actual fatigue within minutes and resumed operations based on further analysis.

Summary of Business Case for Real-Time DRMS
Real-Time DRMS for Operators
Business Objectives No Real-Time MonitoringWith DrillASSURE™ Real-Time
DRMS
Reduce Cost Per Well Drilled /
Decrease Number Of Days To Drill A
Well
Mitigation measures are REACTIVE
and often leads to NPT when
operation stops to assess situation
and perform analysis. Ex. “Loop
Currents”
Allows a PROACTIVE response to
integrity issues. KPI indicators give
quick visual “Go-No Go” to Rig Ops
Team.
No Harm To Environment, Personnel,
Or Company Reputation
No real time feedback to proactively
prevent an undesirable event such as
wellhead, riser, or conductor failure.
Real-Time feedback can be used to
proactively detect and mitigate
undesirable events. Helps to address
any regulatory scrutiny by showing
due diligence.
Asset Life ExtensionNo insight into wellhead fatigue life
utilization and risk/uncertainty
increases as asset ages.
Historical record of wellhead integrity
can be captured over its life cycle.
This can result in asset life
optimization and maximum return on
investment.
Every hour saved on an offshore operation is a savings of $20,000 to $50,000 per hour.
