ExxonMobil Multiple Locations 2003 - 2024

Joint Interest Asset Manager, Lagos, NG Aug 2021 – Feb 2024

• Managed ExxonMobil’s non-operated interest in 3 oil fields with IOR projects totaling ~200kBD in production; this included overseeing audits, implementing governance processes, monitoring budgets, and managing technical and operational issues

• Built and leveraged relationships with operators and CoVs to provide competitive intelligence to my organization

• Managed audit scope and reconciliation resulting in $5M recovered from the operator

• Interfaced with operator and CoVs on project scope, cost and schedule of 2 multi-billion deepwater projects. Provided routine updates to my organization. Managed discussions on technical and economic evaluation differences

• Led economic and technical evaluations for potential acquisitions, partnerships, farmouts and divestments to improve value of discovered assets

Subsurface (Reservoir & Geoscience) Team Lead, Houston, TX Apr 2019 – July 2021

• Led subsurface teams in the review of operations, processes, and production levels of 2 large assets (Tengiz and Kashagan) totaling

~1.5MOEBD with > 60GB STOIIP to maximize base value and determine feasibility of additional investments

• Managed EOR program (miscible high H2S pattern gas flood) at both assets. Maintained compositional models to support asset and project activity

• Leveraged data from reservoir simulation models to generate multi-scenario forecasts crucial for investment decisions in major drilling projects (including a >$50G Tengiz Expansion Project); prepared and delivered annual presentations to secure capital for various reserve-adding projects to upper management

• Designed data acquisition and reservoir surveillance programs to improve reservoir characterization and accuracy of existing models

• Utilized an integrated production model to justify debottlenecking resulting in ~10 kBD incremental production

• Participated in multiple discipline and multi-functional peer reviews to support major non-operated projects as they progressed through the value assurance process; utilized financial modeling techniques to assess project economics, evaluate risks, and optimize investment decisions

• Led annual reserves assessments and updates for internal, SEC and PRMS submissions

• Spearheaded the use of updated reservoir characterization & simulation forecasts to justify a ~20% increase in Proved Reserves at a major asset

PROFESSIONAL EXPERIENCE continued

Reservoir Engineering Advisor – Africa Region, Houston, TX Aug 2017 – Mar 2019

• Directed quality assurance efforts across multiple African locations (Nigeria, Angola, Mozambique, Chad, & EG) ensuring adherence to technical standards, securing requisite technology, maintaining tool uniformity, and assembling the appropriate personnel; facilitated clear communication of evaluation criteria, thereby enhancing the quality of investment proposals

• Collaborated closely with ExxonMobil SMEs to implement technical guidelines and industry best practices

• Conduct gap analyses for technical teams and make recommendations on updated processes, implementation of new technology, required training and hiring/transferring the right staff to improve the business

• Led multi-functional technical challenge workshops, convening representatives to review all major assets, including reservoir performance and technical workflows, to maximize productivity and achieve project milestones Reservoir Engineering Supervisor, Lagos, NG Mar 2011 – Jul 2017

• Managed reserves stewardship for over 50 fields; developed documentation for over 1 GOEB reserves, ensuring compliance with internal, SEC, and government (PRMS) reporting. Led quarterly & annual internal reviews and 3rd party audits

• Collaborated closely with geoscientists to build or update static and dynamic reservoir models, conduct uncertainty analyses, design simulation studies to integrate all relevant data (including 4D monitors), and generate production forecasts for the organization’s largest portfolio of simulation studies

• Supported major investment decisions including an 8-well redevelopment on a deepwater West Africa asset, resulting in

>100 MBO incremental recovery

• Partnered with Treasurers and Controllers to secure over $3B in reserves-based lending; forecasted oil production and served as the primary interface with third-party Lender’s Reserves Consultants (NSAI) on 3 projects

• Supported the execution of multiple brownfield projects, including negotiating agreements, managing contracts, and overseeing project implementation and integration into existing operations.

• Collaborated with field operations to devise comprehensive data acquisition plans, facilitating a structured approach to managing and leveraging data pertinent to reservoir surveillance and management, thereby optimizing production

• Developed depletion plan recommendations at a major asset with high-GOR production resulting in ~5% in GOR with a similar increase in oil production

• Managed annual field and wellbore utility reviews: potential for infills/downspacing, production & injection diagnostics (Decline Curve Analysis. Rate vs Time, Hall Plot, Oil Cut vs Cum Oil, etc.) for 20+ fields and 300+ wells

• Developed annual personal goals and asset KPIs to technical staff that support the business unit’s objectives Corporate Planning Analyst, Lagos, NG Feb 2009 – Feb 2011

• Orchestrated the annual forecasting and budgeting processes for the affiliate, including monthly reconciliation of asset & project performance against key corporate metrics. Worked with C-Suite and Operations executives to identify areas for improvement

• Provided technical input to financial reporting including production and reserves forecast pertinent to computing depreciation Reservoir Simulation Engineer, Houston, TX Feb 2006 – Jan 2009

• Partnered with geoscientists and other functions to build pre-development reservoir simulation models for multiple deepwater projects in West Africa, crucially supporting significant investment milestones

Worked with cross-functional teams to create development plans for deepwater fields; outcome included well count/placement, optimal completion type and length, SURF layout, drilling and start-up sequence to maximize data capture, etc. Approved plans required risk mitigation plans to address risks and uncertainties in the development decisions Reservoir Engineer – Business Development, Lagos, NG Jun 2003 – Jan 2006

• Provided reservoir engineering support to progress multiple pre-development and brownfield projects through ExxonMobil’s project value assurance process; activities included rate and reserves estimation, network modeling, economic evaluation, integration of exploration and appraisal drilling findings results (including formation evaluation and PTA/RTA) into multiple black oil reservoir modeling/simulation updates, writing and updating Field Development Plans, and advocating for approval with regulatory bodies.
