Responsibilities

Lead the reservoir engineering function across reservoir management, field development planning, production forecasting, reserves and resource assessment, and completion and development optimization for conventional and unconventional oil and gas resources.
Build, organize, and develop a multidisciplinary reservoir engineering team, including defining roles, accountabilities, governance interfaces, technical assurance processes, and capability development priorities.
Create practical workflows, processes, data standards, peer reviews, and decision frameworks required to stand up a new upstream company and enable consistent evaluation, planning, and investment recommendations.
Support the design and implementation of the company's upstream operating model, including interfaces with subsurface, drilling and completions, operations, commercial, legal, finance, business development, and executive leadership.
Lead integrated development optimization for the South Mansfield asset, including well spacing and stacking, landing-zone selection, drilling sequence, lateral length, completion design, parent-child and depletion effects, and surveillance and data-acquisition planning.
Own type curves, production forecasts, reserves inputs, uncertainty ranges, and performance lookbacks, applying material balance, rate- and pressure-transient analysis, decline-curve analysis, and numerical simulation as appropriate.
Provide technical and commercial leadership for opportunity screening, technical due diligence, valuation, portfolio prioritization, asset maturation, and post-acquisition integration for acquisitions, divestitures, joint ventures, and farm-ins worldwide.
Lead reserves and resource evaluation consistent with applicable SEC and SPE-PRMS requirements, coordinate with independent reserves auditors, and maintain auditable forecast, reserves, and economic assumptions.
Direct well, project, asset, and portfolio level economics, including NPV, IRR, payout, breakeven, scenario, and sensitivity analysis, and provide production and supply forecasts supporting integrated gas, LNG, and corporate planning decisions.
Integrate geoscience, engineering, operations, economics, commercial terms, regulatory considerations, and stakeholder inputs into decision-quality recommendations.
Lead or support the engagement, contracting, and management of consultants, third-party engineering firms, technical software providers, and related budgets while retaining clear internal ownership of assumptions and decisions.
