Field Data Acquisition: Lead and support geophysical surveys using in-house survey equipment such as ERI, GPR, EM and HVSR.
Site Investigation: Assist in the design of survey programmes to identify subsurface risks like voids, utilities, or varying bedrock depth and integrate findings with geotechnical and geoenvironmental teams planning intrusive investigations.
Support the design of third party onshore surveys such as MASW, 2D reflection and refraction, wireline and cross-hole seismic, providing field supervision.
Support the design of third party near-shore marine surveys such as SBP, Magnetometer, 2D reflection and refraction, providing field supervision (offshore certification and training provided).
Data Processing and interpretation: Utilise industry-standard software (e.g. Res2DInv, Geolitix) to process raw field data into actionable models.
Assist with the interpretation of 2D and 3D seismic datasets (IHS Kingdom). Conduct structural analysis and fault mapping using geophysical, borehole, and field data and integrate with other datasets to support subsurface evaluations.
Develop an understanding of the underlying requirements of our clients, and how we can meet those requirements.
Reporting: Technical writing of factual and interpretive reports, ensuring high-quality visualisations and clear recommendations.
Safety & Logistics: Manage field equipment maintenance and uphold strict Health & Safety standards on-site.
