Senior Geophysicist - Onshore & Offshore
Our client, EGS is a multi‐national organisation operating in Europe, America, Asia and Australia. EGS provides a wide range of marine surveying services to the telecommunications, renewables, oil & gas, charting and marine infrastructure sectors.
Due to an increase in demand for EGS services based out of Australia, we are seeking an experienced geophysicist to work at the Western Australian branch for both onshore and offshore responsibilities.
The Role
Based at the EGS branch in Fremantle, the successful candidate will work on projects based in Australia and globally, both onshore (office‐based) and offshore surveying. The estimated workload is:
Onshore
Mainly based in Fremantle with additional land‐based project work in Australia & overseas: approximately 60% of the time.
Offshore & Inshore
Northwestern Australia, Australia & international: approximately 40% of the job – 90 to 120 days per year, with additional leave accrued while offshore.
The senior geophysicist should be a specialist in 2D multichannel seismic for offshore surveys, with expertise in acquisition, processing and interpretation of marine 2D multichannel seismic data, particularly in support of the growing offshore wind farm market in Australia. The successful candidate will lead the multichannel seismic component of our geophysical site surveys and work alongside a global team of experts.
The office environment is relaxed, with flexible start/end times and partial working from home possible. The working week is 38 hours.
Key Responsibilities
* Equipment setup & offshore acquisition: Lead setup, calibration and offshore acquisition of 2D multichannel seismic data using airgun or sparker sources and multichannel 2D streamers.
* Seismic data processing: Process seismic reflection/refraction datasets. Proficiency with both prestack and poststack workflows is required.
* Seismic interpretation: Perform detailed interpretation of seismic data and integrate with other geophysical and geotechnical datasets to support engineering design, not reservoir exploration.
* Reporting: Write comprehensive reports summarizing findings, interpretations and recommendations.
* Offshore work: Involvement in field work – preparation, mobilisation, calibration and oversight of multichannel seismic surveys, with an average of around 90 days offshore work per year.
* Office‐based work: Full‐time role based in the Fremantle office when not offshore or on leave, involving project planning, data processing and reporting.
The Candidate
Qualifications and experience:
* Offshore data acquisition: Proven experience with equipment setup, calibration and execution of offshore 2D multichannel seismic systems.
* Seismic data processing: Expertise in processing 2D multichannel seismic data, including both prestack and poststack workflows.
* Seismic interpretation: Strong ability to interpret marine seismic data, providing logical geological insights.
* Technical reporting: Excellent skills in writing technical reports and presenting seismic data findings clearly and concisely.
* Preferred skills: Experience with side‐scan sonar, subbottom profilers (single‐channel, zero‐offset), magnetic gradiometers (particularly for UXO surveys); familiarity with geotechnical surveys (CPT, vibrocore, piston core, boreholes); ability to integrate geophysical and geotechnical datasets.
As part of the global EGS Group, you will contribute to surveys supporting offshore wind farms, oil and gas, telecommunications, defense and nearshore construction projects. The majority of the work is in offshore and nearshore marine environments.
This is a unique opportunity to specialise in marine 2D multichannel seismic while gaining exposure to a variety of geophysical and geotechnical techniques.
EGS values a positive workplace with flexible working conditions built on trust and accountability. The company operates year‐on‐year growth and welcomes innovation with new technologies such as AI, autonomy and advanced communications.
