Abstract
The Wells Front-End Loading (FEL) workflow is a critical phase in the planning and design of oil well projects, enabling efficient cost optimization and decision-making before project execution. However, the current FEL workflow suffers from inefficiencies caused by manual registration, localized record-keeping, repetitive iterations, and dynamic stakeholder expectations influenced by oil price uncertainties. Furthermore, fragmented data connectivity and the unavailability of legacy data hinder seamless data flow and digital adoption throughout the well life cycle.
To address these challenges, this paper introduces Wells Front End Engineering Nexus (FENEX), a centralized web-based workflow platform that digitalizes the FEL workflow and offers anywhere and anytime accessibility. The FENEX application is supported by the Well Planning Suite (WPS) as the orchestrator to enable the execution of FEL workflow, perform detailed engineering design and ensure a smooth handover to the execution team. This manuscript presents FENEX as a comprehensive solution for improving the FEL workflow. It highlights the FENEX dashboard, critical roles of WPS and some enhancement features, i.e. introduction of features of "Campaign", workflow integration & approval process amongst the Field Development Plan (FDP) team & Technical Assurers (TA), guided workflow for well engineering and input for efficient project tracking & monitoring via FENEX. In the effort to realize FENEX, this paper will also discuss the key challenges in managing the segmented well databases between well design planning and well operational records which could impair the seamless data connectivity throughout the whole well life cycle. As such, a drastic reshaping of the data landscape was required to mitigate this where all data are consolidated into one Cloud database, wellSCAPE promoting a single source of truth for all well design, planning and operational records data.
The implementation of FENEX addresses the limitations of the current FEL workflow, streamlining processes, enhancing efficiency, and reducing costs. By centralizing project data and promoting seamless data connectivity, FENEX overcomes the challenges of localized record keeping, fragmented data landscape, and the absence of legacy data. The platform empowers stakeholders to make informed decisions, optimize value extraction, and drive digital adoption in the oil and gas industry.
The introduction of FENEX represents a significant step towards efficient collaboration, optimized value extraction, and enhanced evaluation efficiency. The findings of this study provide valuable insights for industry professionals seeking to streamline the FEL workflow and leverage digital tools to achieve project success in a rapidly changing energy landscape.
