Wellhead Fatigue Monitoring: Real-Time Drilling Riser Monitoring ROI Case Study
1 like1,525 views
The document discusses the importance of real-time drilling riser monitoring systems (drms) for operators, highlighting how they help track wellhead and conductor integrity under environmental stresses to mitigate risks of operational failures. It emphasizes the cost-saving benefits of implementing such systems, with data showing that a single day of rig time saved can cover the system's operational costs. Additionally, the document outlines how real-time data can enhance decision-making, reduce non-profitable time, and extend asset life through proactive monitoring and risk management.

- 2. www.pulse-monitoring.com 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

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% -100% -50% 0% 50% 100% 150% 200% 250% 300% 350% 1 24 47 70 93 Rig Time Saved (Hours) REAL TIME DRMS - RETURN ON INVESTMENT Payback achieved with <1 day of rig time saved. * RigLogix April 2015
- 6. www.pulse-monitoring.com 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.
