Seismic interpreter

Seismic interpreters use a variety of technical, computational and scientific modelling techniques to produce geophysical and geological data that can be used to analyse the hydrocarbon content of rock structures.

The number of opportunities within the profession and the resulting competition for vacancies is affected by fluctuations in the world oil market.

Seismic interpreter job description: Typical employers | Qualifications and training | Key skills | Useful links | Find jobs and courses

Seismic interpreters assess the amount of oil and gas contained within rock structures, the ease of which it can be extracted and the likelihood of encountering any hazards or problems in the process.

Key tasks include:

producing and interpreting computer-generated 2D and 3D models;
using sound waves to produce geological structure maps;
gathering data about the earth’s surface from acoustic readings, surveys and satellites;
producing maps and cross sections of the earth’s structure;
recording and analysing numerical and scientific data;
using specialist computer modelling applications to replicate seismic responses and hydrocarbon production;
predicting likely changes and movements in rock structures;
collecting information about rock volume and quality that can be used to measure the likely yield of oil or gas;
writing scientific papers and reports;
advising, liaising and consulting with colleagues, clients, consultants, researchers, external bodies and other professionals.

Typical employers of seismic interpreters

major oil extraction, exploration and production companies
public sector organisations
British Geological Survey
educational establishments
research and development organisations
Natural Environment Research Council (NERC)

Seismic interpretation is a specialist area of employment with only a small number of vacancies occurring each year. Opportunities are advertised via the Internet, by careers services, specialist recruitment agencies, in national newspapers and in relevant publications such as Geoscientist and the Petroleum Exploration Society of Great Britain (PESGB) Newsletter.

Qualifications and training required

A strong academic background, together with good technical, IT and mathematical skills is essential for all candidates. As a minimum it is necessary to possess a good degree in an appropriate subject (geophysics, geology, geotechnology, physical or applied sciences and mathematics).

A relevant postgraduate qualification in geosciences, petroleum geology etc. is beneficial, and may be a requirement for some opportunities. Pre-entry work experience can be difficult to obtain, but is helpful for entry into the profession.
