Job Description

Within the Geology team, you will interpret surface and subsurface data to build 3D geological models and to generate, mature and evaluate natural hydrogen prospects, primarily in onshore settings (mountain belts and foreland basins / fold & thrust belts). Your interpretations will directly shape Mantle8's exploration decisions.

You will be involved across the entire exploration chain, from screening to prospect generation (alongside geophysicists and geochemists) through to maturation, working at both the regional and the play scale. As seismic data is sometimes scarce or only historical, the ability to deliver results with limited data is essential.

Your Mission

Interpret and integrate seismic, geological and subsurface data to generate H₂ prospects in fold & thrust belt settings — firmly grounded in real data, not generic models.

Fold & Thrust Belt — structural mapping, onshore settings

2D/3D Seismic — structural & stratigraphic interpretation, from regional to play scale

H₂ Prospects — target generation & maturation through to drilling

Multidisciplinary teams — Geology

• Geophysics
• Geochemistry
• Drilling

Key Responsibilities

Subsurface interpretation & characterization

• Interpret and integrate seismic, geological and subsurface data to characterize structural and reservoir geology (fold & thrust belt, onshore), at both regional and play scale
• Perform 2D/3D seismic interpretation — structural and stratigraphic — and map H₂ prospects
• Collect, compile and analyze legacy O&G and/or mining data (surface and subsurface), including in data-scarce settings

Prospect generation & maturation

• Contribute to the screening, generation and maturation of natural hydrogen prospects, through to the definition of drilling targets
• Generate leads through advanced interpretation techniques and new datasets
• Build integrated subsurface models within multidisciplinary teams, working closely with geophysicists and geochemists

Communication & decision support

• Communicate technical results and recommendations to support project evaluations
• Take part in prospect reviews and exploration decision-making

What We Offer

• The exploration of a new energy — natural H₂, a genuine scientific frontier
• Real data across a variety of onshore basins (fold & thrust)
• A central technical role within the Geology vertical
• Grenoble — a scientific environment and an alpine setting
• A passionate, international and multidisciplinary team with a startup culture
• Direct impact on exploration decisions

Requirements

Essential

• Master's degree in applied geosciences (e.g. reservoir engineer / geologist)
• 5 years + of experience in the O&G industry / geosciences
• Proficiency in 2D/3D structural & stratigraphic seismic interpretation, from regional to play scale
• Experience in fold & thrust belt settings (onshore)
• Ability to work with limited data and to source / compile data (legacy, fieldwork)
• Autonomy and analytical rigor, while collaborating effectively within a multidisciplinary team

Nice to have

• An all-rounder profile: structural geology + seismic interpretation + 3D modeling
• Software: Move, Petrel
• O&G experience in an early-stage exploration context
