Responsible for developing, maintaining, and optimizing estimates, cost models, and scope-based forecasting tools that support business process, service quality, and continuous improvement initiatives across the oil and gas value chain. This role owns moderately complex estimating activities from initial concept through execution support, translating business, operational, and project requirements into accurate, scalable estimating solutions that improve planning quality, cost visibility, and decision-making.

Partners with Operations, Engineering, Project Management, Supply Chain, Finance, and other stakeholders to define estimating assumptions, evaluate alternatives, and deliver fit-for-purpose cost and resource estimates aligned with safety, regulatory, operational, and service expectations. Applies estimating discipline, process knowledge, and data-driven insights to strengthen project controls, improve estimate quality, and support consistent execution across assets, facilities, and business initiatives.

Essential Functions and Responsibilities

• •Estimating Strategy & Estimate Development
• •Develop and prepare moderately complex project estimates, cost models, and resource forecasts for business process, service quality, operational improvement, and related project initiatives.
• •Define estimate bases, assumptions, exclusions, and estimating methodologies appropriate to scope, maturity, and project complexity.
• •Translate technical, operational, and business requirements into structured estimates that support planning, prioritization, and execution decision-making.
• •Evaluate estimate quality and recommend adjustments based on scope changes, market inputs, historical performance, and execution risks.
• •Support development of estimate packages and documentation that can be consistently applied across projects and initiatives.
• •Project Controls, Cost Analysis & Forecasting
• •Analyze labor, materials, equipment, contractor, and indirect cost inputs to develop accurate and supportable cost projections.
• •Monitor estimate-to-actual performance and identify trends, variances, and opportunities to improve forecasting accuracy.
• •Maintain cost benchmarks, historical databases, unit rates, and estimating reference information to strengthen future estimating efforts.
• •Support scenario analysis, what-if modeling, and alternative evaluations to inform project and business decisions.
• •Collaborate with project controls and finance partners to align estimates with budgets, forecasts, and reporting requirements.
• •Business Process & Service Quality Improvement
• •Identify opportunities to improve estimating processes, templates, workflows, and data quality to increase consistency, efficiency, and usability.
• •Standardize estimating practices and documentation to support repeatable execution and stronger quality control across the organization.

• •Support implementation of process changes, system enhancements, or digital tools that improve estimating capability and reporting quality.
• •Promote disciplined estimating practices that align with operational needs and quality expectations in an oil and gas environment.
• •Stakeholder Collaboration & Cross-Functional Support
• •Partner with Operations, Engineering, Project Management, Supply Chain, Finance, and other stakeholders to gather scope information and validate estimate inputs.
• •Facilitate alignment on assumptions, risks, schedule drivers, and resource needs to ensure estimates reflect business and operational realities.
• •Communicate estimate development approach, key drivers, risks, and recommended actions to stakeholders and leadership.
• •Serve as a knowledgeable resource for estimating methodologies, cost modeling, and estimate quality practices.
• •Support cross-functional planning and prioritization by providing clear, timely, and decision-ready estimating information.
• •Risk, Governance & Documentation
• •Identify estimate risks, uncertainties, and key cost drivers and incorporate them into estimating assumptions and documentation.
• •Maintain clear records of estimate methodologies, revisions, approvals, and supporting data to improve auditability and traceability.
• •Ensure estimating outputs align with internal controls, project governance expectations, and applicable company standards.
• •Support reviews of estimate quality, process compliance, and documentation completeness.
• •Contribute to building scalable estimating practices that reduce rework and support consistent decision-making.
• •Analytics, Reporting & Decision Support
• •Prepare estimate summaries, dashboards, and reporting materials that support business planning and project reviews.
• •Analyze estimating data to identify patterns, lessons learned, and opportunities to improve quality and predictability.
• •Provide insights that help stakeholders evaluate project alternatives, prioritize investments, and manage execution risk.
• •Support leadership decision-making through clear analysis of estimate changes, assumptions, and cost impacts.
