Asset Performance Manager at Heritage Energy Operational Services Limited

Department: Technical

Job Summary

• The Asset Performance Manager (APM) is a senior leadership role within HEOSL, reporting functionally to the General Manager Reservoir Development and Strategic Integration and working closely with the COO, accountable for maximising asset value through integrated planning, disciplined execution and performance optimisation across the full production value chain, while acting as the single point of integration to ensure plans are delivered, deviations are actively managed, and performance excellence is achieved.

Key Accountabilities
Asset Value Delivery & Ownership:

• The APM is accountable for influencing and driving the delivery of safe, reliable, efficient production, providing clear leadership and integration across the full value chain to ensure that asset performance meets or exceeds business expectations.
• The role drives disciplined execution and sustained performance improvement by aligning operational delivery with strategic objectives and ensuring that value is consistently realised from the asset.
• The APM leads the optimisation of production and uptime, reduction of deferment, improvement in operating cost per barrel, and enhancement of asset recovery and lifecycle performance.
• The role drives economic decision-making and prioritisation across all activities within the Asset, ensuring that resources are deployed to maximise value and that trade-offs are understood and actively managed.
• The APM ensures that asset performance remains fully aligned with HEOSL strategic objectives and JV partner expectations, providing clear visibility of performance, risks and opportunities.

Integrated Planning & Delivery (ADP Ownership):

• The APM owns the development, integration and delivery of the Asset Development Plan (ADP) across all disciplines, ensuring it represents a ‘single source of truth’ perspective of the asset. The role ensures full alignment between long-term (20Q), mid-term (8Q) and Annual Operating Plan (AOP) horizons, maintaining consistency between strategic intent and executable plans.
• The Asset Performance Manager supports the translation of strategy into prioritised, deliverable work programmes with clearly defined value outcomes, ensuring that plans are realistic, integrated and aligned with cross-functional resources and constraints.
• The APM actively manages the ADP with a dynamic approach, evolving in response to changes in reservoir performance, operational conditions and commercial drivers, while maintaining focus on delivering sustained asset value.

Performance Management & Intervention:

• The APM is accountable for defining and governing a robust asset-wide framework for performance management and intervening when performance is (observed as potentially) degrading. The framework covers production delivery, capital efficiency, risk exposure and plan adherence.
• The Asset Performance Manager supports regular COO-chaired performance reviews, providing clear visibility of performance against plan and identifying gaps and emerging risks.
• Through active engagement, the role challenges stakeholders on delivery performance and drives corrective action where required, escalating to the COO as necessary, and ensuring that underperformance is addressed.
• Critical delivery risks are escalated appropriately, with the APM supporting and driving resolution.

Portfolio Optimisation, Functional Alignment & Decision Support:

• Portfolio optimisation, functional alignment and decision support focuses on identifying and prioritising asset opportunities based on value, feasibility and readiness; while ensuring plans, resources and execution are fully aligned within a single integrated asset plan.
• The Asset Performance Manager drives system-level optimisation by breaking down functional silos and ensuring decisions maximise overall asset value.
• Through structured challenge and targeted intervention, the role tests business cases, assumptions and delivery plans, and leads trade-off decisions across competing priorities such as production, reliability, cost and long-term value.
• This enables clear, data-driven recommendations to leadership and JV partners, supporting timely decisions and maximising value delivery.

Risk & Resilience Management:

• Accountable for the verification of all safety, production, delivery, and operational risks, that they are comprehensively identified, assessed and appropriately mitigated across the asset. The APM ensures that risk exposure is fully understood and transparently managed. The APM validates that robust contingency plans are in place and that sufficient resilience is embedded within the ADP to respond effectively to deviations and emerging risks.
• The APM role ensures that asset risks are consistently communicated, visible and escalated in a timely manner to senior leadership and JV partners, with a clear articulation of potential impacts, mitigation strategies and decision requirements.
• Through this, the APM supports and reinforces disciplined risk management and informed decision-making.

ESG, HSE & Sustainability Integration:

• The APM ensures that safety is treated as a non-negotiable priority, while emissions management and reduction, particularly greenhouse gases, are actively incorporated into planning and operational decision-making.
• Environmental compliance is consistently upheld through cross-functional integration, with ESG factors embedded within both planning and optimisation processes to ensure that asset performance is delivered in a way that balances operational efficiency with long-term sustainability.

Leadership & People:

• Responsibilities centre on leading and developing a high-performing Asset Performance Team, while building a strong culture of accountability, data-driven decision-making and collaboration across functions. The APM acts as a visible leader and integrator across the asset, influencing behaviours beyond direct reports and reinforcing performance discipline and alignment.
• The role also involves coaching and guiding stakeholders in integrated planning, prioritisation and performance delivery, ensuring consistent application of best practices and strengthening capability across the wider organisation.
