Deployment of Innovative Mathematical Decision Model Leveraging Operability & Trouble Shooting Enhancement for Remote Facilities

Abstract In oil field, assets are remotely located which possess big challenges to logistics, resources mobilization and substantial time is consumed in front end troubleshooting during operational disturbance or equipment downtime. The solution presented in this paper highlights decision model deployed over Process Data obtained through DCS (Distributed Control System) and Enterprise Process Information Database. Logical model contains causes & remedies derived from FMEA (Failure Mode & Effects Analysis), and operational manuals for critical equipment to facilitate faults finding and troubleshooting. It was conceptualized to develop mathematical decision model based on critical operating parameters utilizing web-based Process system. FMEA Decision models are comprised of respective failure causes and remedial actions, interlinked with PI system to improve availability and reliability of equipment. Customized dashboarding was established to consolidate real time critical parameters monitoring to take proactive actions on any abnormality. Alerts are configured to recognize deviations; any parameter reaches to alert value, cell color changes to Yellow and through analyzed data /mathematical model email notification is sent to concerned with causes and remedies for quick follow up. To realize Pilot concept, Studies carried out on failure causes, operating procedure, causes & remedial actions and operating parameters-based troubleshooting to develop FMEA Mathematical/Decision Models for each case. Oil producing wells, MPFM, MSMs, multi-phase pumps, Utilities, flare system were assessed and all critical parameters consolidated in customized dashboard to have effective monitoring and quick analysis to avoid nuisance trips. Following benefits pertain to Process safety, Operating Integrity, equipment availability / Business Continuity, Sustainability/ Emissions reduction achieved. Real time monitoring of Annulus pressure for ensuring Well Integrity of +300 wellsProactive and timely operation & maintenance troubleshooting, assisted in ensuring +30 wells availability >95% and reduced the downtime.Continuous Production Gain, 500 BOPD (25k USD) / well. Real time wells production analysis with respect to differential pressure across choke valve.Ensuring uninterrupted chemical dosing system operation, improved Pipeline integrity by keeping 1 pump operation all times.Improved Predictive Intervention by adding Alarms/Analysis ToolsIdentifying all flare sources, their characteristics and process parameters to quantify flaring volume.20% reduction in flaring achieved due to this proactive approach, equivalent to 1050 metric ton / Year.Proactive approach for ensuring Operating integrity and Process safety, ensuring good health of F&G system.Knowledge buildup of the team for effective troubleshooting. Preserving critical functions of major equipment and during any operational or maintenance intervention by operator/maintenance technician, before proceeding to remote location, requisite resources can be proactively arranged which will save time and quality of intervention (Maintenance / Operations corrective actions) can be executed to avoid recurrences and achieve uninterrupted production. Successful concept deployment resulted in achieving multiple benefits for remote facilities operation.
