This is a course for practising seismic interpreters tasked with creating depth maps and estimating uncertainty for volumetrics and well planning. Time is split equally between teaching and exercises which are designed to illuminate concepts and cement understanding through hands-on application. The course incidentally provides attendees with insights into seismic imaging, tips on mapping & interpretation, and several efficiency-enhancing spreadsheets to take away.

A basic understanding of geology, structural interpretation and the seismic method is required. Experience in mapping and seismic interpretation will be a significant advantage.
The Depth Conversion methods & Pitfalls course is available through the RPS Group training organisation. Members of their Nautilus Training Alliance (NTA) should contact RPS directly in order to book places or to arrange in-house training.
Oil companies, service companies who are not members of RPS’ NTA but who are interested in running the course should contact Alan Atkinson, the course creator and presenter, at Rockflow to enquire about in-house courses. Individuals may also contact Rockflow to enquire about possibilities for participating in a course.
Alan has over thirty five years of exploration, field development, and production geoscience experience with operators in West Africa, South Asia and the North Sea.
Specialising in the application of high end geophysics to structural and stratigraphic seismic interpretation, his areas of expertise are reservoir characterisation (using pre-stack inversion, AVO analysis) and velocity modelling (pre-stack depth migration and depth conversion).
He started his career working the North Sea with Phillips Petroleum and Amerada Hess in London, and subsequently moved to CNR International, working Angola and Côte d’Ivoire. He then moved to Cairn Energy, living and working in India, and becoming Chief Geophysicist during their successful Rajasthan campaign. Here, he supervised several significant seismic acquisition and processing programmes, and managed a geophysical studies team undertaking, amongst other projects, AVO modelling work and pioneering 4D studies on India’s largest onshore fields. He is now a partner in Rockflow Resources Ltd, a specialist technical and management consultancy serving the international petroleum industry, primarily advising on reserve evaluations for a variety of clients worldwide and providing services as an Expert Witness in oil and gas disputes. He is also an honorary lecturer at Imperial College London.
Alan devised the ‘Depth Conversion Methods & Pitfalls’ course in 2009 and ‘Depth Conversion Methods & Petrel Workflows’ two years later. The courses have been delivered around 60 times to audiences across the world. He is a Fellow of the Geological Society, and an active member of SEG, EAGE and PESGB.
