Geophysical data processor
A geophysical data processor uses the most modern and sophisticated sonic, electronic, electrical, seismic, or gravity-measuring instruments to convert raw geophysical data (usually large volumes of seismic data) into a user friendly format. The converted data is then analysed by interpreters in order to determine sub-surface geology. Often, this data is used to identify potential oil-bearing rock layers.
Processors work in teams, often on many different projects simultaneously. The processing sequence is tailored to individual projects depending on geology, data acquisition techniques, time and financial constraints.
Frequent client interaction is essential as is the ability to develop expertise in state-of-the-art software.
Typical activities include:
A relevant physics, mathematics or applied science degree may increase your chances:
A 2:1 or higher is usually sought by employers, although, at times when demand for processors is high, it may be possible to obtain a graduate position with a 2:2. In addition to a relevant degree, good A-levels (or equivalent) are also required as is a high level of numeracy and computer literacy.
Entry with an HND only is not possible - the necessary scientific background can be obtained only through study to degree level.
A postgraduate qualification in a relevant course (such as a Masters degree in geophysics or petroleum geology) may improve employment prospects and enhance starting salaries.
Much of the information generated within this field is subject to data and software privacy restrictions and so finding work experience opportunities can be difficult. Gaining an awareness of the industry as a whole, from reading broadsheet newspapers and industry publications or through joining relevant societies, can help in interviews and will show a prospective employer you are a serious candidate.
Candidates need to show evidence of the following:
A driving licence and evidence of good health may be required for some postings.
This is generally considered a competitive industry, although there can be dramatic fluctuations in the employment market according to changes in the price of oil. Opportunities for employment tend to be greater during periods when oil prices are high, when it is economically viable to seek out new oil reservoirs. Oil Careers is a useful resource for those wishing to enter the industry.

The volume of seismic data typically processed today is so vast it takes huge 'supercomputers' days, even weeks, to run the most advanced processing programs. Geophysical data processors have to get to grips with using unique software and programming languages whilst understanding the fundamental geophysical and mathematical principles upon which the software is based. Undertaking technical training is therefore integral to the role.
Most companies have in-house training centres where new employees will typically spend the first few weeks of their employment. After this, they join a processing team where they continue to receive on-the-job training and instruction from more experienced team members. Short visits back to the training centre for revision and software updates will occur regularly.
In addition to technical training, most employers also place an emphasis on personal and professional development. Recognising that a well-trained workforce generally results in stronger teams and better working relationships between clients and colleagues, employees are usually given access to a range of courses, including project management, time-management, communication, teamwork, supervisory and management skills.
Seismic data processing companies are striving to obtain prestigious quality assurance accreditation. An integral part of this is that all employees are aware of clearly defined best practice procedures. External quality auditors can interview anyone in the building, therefore, it is vital that all employees are aware of what procedures apply to them and, more importantly, keep themselves up to date through relevant training opportunities.
The natural progression for a geophysical data processor is to the role of project leader, usually achievable after two to three years. In this position you would be in charge of a project and have the responsibility of supervising less experienced members of the team. Regular client interaction is also an integral part of the role. Eventually, a processor may be placed in charge of a whole team of processors and be responsible for the quality and timing of a number of projects.
Once a processor has gained a year or two of experience, opportunities may arise to work in processing centres abroad or with data acquisition crews, which are normally offshore. Field work is generously rewarded, but it is not a lifestyle that suits everyone.
Alternatively, a processor may be able to sidestep to another department within the processing centre where they work, e.g. data interpretation or dealing with more specialised and sophisticated processing techniques.
Further opportunities exist in:
Oil companies often use independent consultants to liaise with processing companies on their behalf. These consultants have typically had long careers in the oil industry and can, therefore, demand high fees. It takes many years' experience to be able to define and supervise data processing to the standards required. The work carries a lot of responsibility but is well paid.
An alternative career path option is the finance industry, where a comprehensive knowledge of the oil exploration industry and good head for figures may be sought after.
The main employers are a small number of specialised oil and gas sector service companies, who tend to work on a global scale. These companies are often involved in data acquisition and data interpretation as well as data processing. Typically, they will have processing centres, or dedicated processing facilities in client offices, in a number of different cities worldwide. However, opportunities also exist with public sector and governmental agencies e.g. the United Kingdom Hydrographic Office (UKHO) .
Each processing centre has to bid for work by responding to calls for tender from the local oil company offices (work is won on the basis of price, processing speed and unique processing software). This results in large workload fluctuations. Many companies resolve this problem by offering temporary overseas contracts to personnel in overstaffed processing centres.
Specialist recruitment agencies commonly handle vacancies. Vacancies may also be listed in the oil and gas sector press.
PETEX is a biennial conference and exhibition held in London and organised by the Petroleum Exploration Society of Great Britain (PESGB) . Data processing companies always have a strong presence and attending this event is a good opportunity to meet potential employers under one roof, as well as obtain literature and learn more about the industry.
The Geological Society runs careers information days which cover the full range of geoscience careers and are usually attended by a number of key industry employers. Its website also has a section on careers and posts job vacancies.
