Manager

CNX•Canonsburg, PA

About The Position

The Reservoir Engineer will help convert subsurface understanding into free cash flow generation from Marcellus and Utica unconventional shale assets as part of the Reservoir and Asset Management team. The role includes reservoir analysis and well performance evaluation, development of type curves and decline models, interpretation of DCA/RTA/PTA/DFIT, spacing and completion optimization, economic evaluation, field development planning, and support for the annual SEC-compliant reserves process. The engineer works closely with geology, land, operations, midstream, finance, and corporate reserves. The position may be filled at the Senior Engineer, Advisor, or Manager level depending on qualifications and experience. Higher levels involve broader technical leadership; the Manager level also leads and develops the reservoir engineering team. The role supports integrated development planning for Marcellus and Utica assets, including inventory life, development pacing, portfolio optimization, and capital ranking. It integrates geological, geophysical, petrophysical, operational, and financial data into reservoir models, reserves assessments, and production forecasts. The successful candidate is flexible, detail-oriented, ambitious, self-starting, and prepared to work with a large and diverse asset base. CNX provides equal employment opportunities to employees and applicants in accordance with applicable federal, state, and local laws. The company prohibits unlawful employee harassment based on protected characteristics.

Responsibilities

Perform decline curve analysis, rate transient analysis, pressure transient analysis, DFIT interpretation, and other reservoir engineering evaluations; translate findings into spacing, completion stage design, and production management guidance.
Perform economic analysis, sensitivities, and capital ranking, including quality control.
Develop, maintain, and apply type curves, decline models, and economic evaluations consistent with forecast methodology, reserves controls, and technical standards.
Support integrated development planning for Marcellus and Utica assets, including inventory life, development pacing, portfolio optimization, and capital ranking.
Collaborate with multidisciplinary teams to integrate geologic, geophysical, and petrophysical data into reservoir models.
Analyze pressure-dependent permeability effects on ultimate recovery and optimize drawdown strategy based on the pricing environment.
Evaluate parent/child interaction and frac-hit impacts and recommend mitigation strategies, lateral spacing, and landing targets.
Integrate geological, geophysical, operational, and financial data into reserves and resource assessments.
Develop and update reservoir models and use simulation and analytics to support production forecasting, reserve estimation, and decision-making.
Support the annual SEC-compliant reserves process, including year-end reserves reporting, third-party audit communication, quarterly reconciliations, and reserves-based lending engineering reviews; align reserves classifications with SEC regulations, SPE-PRMS, and internal governance standards.
Benchmark well and asset performance against internal metrics and peer operators.
Use public and private data with the broader team to identify land acquisition targets and provide technical diligence on A&D opportunities, inventory quality, and commercial fit.
Work with field operations teams to optimize well completions and production strategies.
Use data analytics platforms such as Spotfire to analyze large datasets and identify trends, correlations, and opportunities to improve well performance.
Provide technical guidance and mentorship to less experienced engineers and geoscientists.
Stay current with industry advancements, best practices, and emerging technologies relevant to reservoir engineering.
At the Manager level, lead and develop the reservoir engineering team.
