The critical equipment used in deepwater drilling operations is subjected to harsh environmental factors such as loop currents, extreme weather, and high seastates. It is important to understand the effects these environmental variables have on subsea wellhead and conductor integrity. Through the use of drilling riser monitoring systems (DRMS) operational insight into the real-time status of critical equipment such as the Wellhead, Conductor, BOP, and Riser can be instantly evaluated allowing for safe and efficient decision making. A business case and ROI justification is presented in order to show that a DRMS can reduce Non-Profitable Time (NPT) and Invisible Lost Time (ILT) and is financially justified by saving as few as 1 day of rig time.

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. -150%

Summary of Business Case for Real-Time DRMS
Real-Time DRMS for Operators
Business Objectives No Real-Time Monitoring
With 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 Extension
No 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.
