Subsurface interpretation that turns legacy data into drillable decisions
2D/3D
Legacy and modern seismic volumes handled
PhD-led
Senior technical review on every interpretation
Overview
Most Nigerian operators are sitting on more subsurface data than they have interpreted. Our geoscience practice exists to close that gap: reprocessing, reinterpreting and integrating legacy 2D and 3D volumes, well logs and core data into a coherent subsurface picture.
Interpretation work is led by senior geoscientists and independently reviewed before issue. Where the data does not support a conclusion, we say so. An honest uncertainty range is more valuable to a drilling decision than a confident map that cannot be defended.
We also deliver surface geoscience: geological mapping, site investigation and survey control for infrastructure, mining and environmental scopes.
Capabilities
Disciplines within g&g services
Each of these can be contracted individually or combined into an integrated scope.
Geological Services
Regional and prospect-scale geological studies, sedimentology, biostratigraphy coordination, petrophysical evaluation and integrated basin analysis.
Geophysical Services
Seismic data conditioning, attribute analysis, inversion support, potential field studies and near-surface geophysics for site investigation.
Reservoir Studies
Static and dynamic reservoir characterisation, volumetric estimation, uncertainty analysis and development concept screening.
Seismic Interpretation
Structural and stratigraphic interpretation, fault framework building, horizon mapping, depth conversion and prospect risking.
Geological Mapping
Field mapping programmes, outcrop studies and GIS-based geological map production for exploration and mining clients.
Surveying
Topographic, cadastral and site survey, GPS control establishment, pipeline route survey and as-built verification.
Asset Evaluation & Field Development Planning
Full-field evaluation, development concept selection, well count and phasing, production profiling and field development plans that stand up to partner and regulator scrutiny.
Geo-Referencing & Navigation Consulting
Coordinate reference system definition and audit, datum transformation, survey QC and navigation support for seismic and drilling operations.
Data Vectorisation, Digitisation & Transcription
Recovery of legacy subsurface data: scanned log vectorisation, composite log digitisation, tape transcription and structured technical data archiving.
Mining Support
Mineral exploration targeting, resource evaluation support and geotechnical input for solid minerals operators and investors.
