The EAGE Interactive Online Short Courses bring carefully selected courses of experienced instructors from industry and academia online to give participants the possibility to follow the latest education in geoscience and engineering remotely. The courses are designed to be easily digested over the course of two or three days. Participants will have the possibility to interact live with the instructor and ask questions.
To help you save on registration fees and better organize your learning path, we are offering Education Packages for all Interactive Online Short Courses and Online EETs. The packages are valid for a period of 12 months, choose between packages of 3, 5 and 10 credits.
This course presents an integrated approach to modern land 3D seismic survey design as it has a key role in the seismic value chain going from acquisition to processing, imaging and inversion & characterization. It will describe the main technology advances in land seismic acquisition: high-channel count single sensor (point receiver), simultaneous source high-productivity vibroseis, broadband and wireless nodal systems. New acquisition technology has in turn inspired progress in processing, imaging and inversion & characterization. Seismic survey designs have changed accordingly, wide azimuth high-density surveys are now the norm in many environments. And the survey design workflow now includes single sensor, single source, simultaneous source, broadband, symmetric sampling, crossspreads, spatial continuity and more powerful 5D interpolation methods. It has also become more integrated, with requirements from processing, imaging and inversion & characterization feeding back to the design and hence acquisition.
The purpose of this course is to understand:
• The main parameters related to land survey design;
• The generic land seismic survey design workflow;
• The impact of the new acquisition technology on survey design;
• How design and acquisition affects processing, imaging and inversion and
characterization.
Acquisition geophysicists who are naturally involved in survey design but also processing geophysicists and interpreters who wish to understand how acquisition programmes can be tailored to tackle their problems. The course may also be beneficial to geoscience (geophysics and geology) students.
Participants are assumed to have basic knowledge of seismic acquisition and processing techniques.
Paul Ras, with more than 20 years industry experience principally with Schlumberger, Paul Ras has worked in land seismic acquisition, survey evaluation & design, data processing, inversion & reservoir characterization. He is currently a geophysical consultant based in the Netherlands, teaching and consulting for Schlumberger NExT and working with geophysics startups. Paul began his career at TNO Institute of Applied Geoscience and Delft Geophysical in the Netherlands, working in software development and as a seismologist on field crews. He then worked in various roles for Geco-Prakla, on crews and in the survey evaluation and design group. After a three year secondment at Saudi Aramco followed by starting up WesternGeco’s data processing center in Saudi Arabia, he moved to inversion and reservoir services working for Schlumberger’s DCS segment based in Cairo. Then came various technical and project management roles mainly involving new technology like the land UniQ acquisition system, land demultiple processing and seismic guided drilling. From 2013 until 2015 he worked as a land area geophysicist for WesternGeco based in the UK. Paul is a graduate in Applied Geophysics from Delft University of Technology in the Netherlands.
