Biography
Andrea Crook, Chief Geophysicist at OptiSeis Solutions Ltd., graduated from the University of Manitoba in 2002 with a B. Sc. in Geophysics. She began her career as a seismic processor at Shell Canada and later moved into the Geophysical Operations group where she honed her survey design skills and worked on many experimental seismic acquisition projects. Building on the knowledge she gained at Shell, in 2008 she joined RPS Boyd PetroSearch and consulted on a variety of seismic programs. In 2011, Andrea co-founded OptiSeis Solutions Ltd., a geophysical acquisition software and survey design company focused on developing innovative acquisition solutions for acquiring high resolution seismic data. She is responsible for seismic acquisition design and sub-surface modeling of Canadian and international seismic surveys as well as seismic acquisition software development.
Description
Seismic acquisition has changed significantly in the past ten years. Recording systems have switched from cabled to cable-less/nodal systems, vibroseis is beginning to replace explosives even in areas with rugged terrain, and high trace density surveys are becoming commonplace.
In this course, we will examine seismic acquisition innovations that are providing remarkable improvements in data quality but that are relatively new in Canada. These include equipment innovations such as low frequency geophones and smaller vibroseis trucks with lower environmental footprint, as well as high-density acquisition methods including slip sweep, simultaneous source, and compressive sensing. The course will cover the benefits of implementing these technologies as well as important considerations for survey design, field acquisition, data processing, and archiving when utilizing these methods. Some Canadian case studies will be reviewed to highlight the feasibility of applying these innovations.
