2018 Innovations in Seismic Acquisition (CSEG)

Overview 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 […]

Seismic Acquisition Innovation, CSEG Virtual Learning Series (VLS)

By Andrea Crook, P.Geoph. Abstract 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, new seismic sources are being developed, and high trace density surveys are changing the way seismic data is acquired, […]

CSEG Technical Achievement Award Citation for Andrea Crook

Andrea’s approach to survey design epitomizes the acquisition best practices experts have been promoting since at least the 1970s, namely, design better surveys based on the geophysics, collaborate with all participants (interpreters, processors, field crews) to achieve project goals, and share knowledge on what geophysics can and can’t do. Andrea has been developing and testing […]

Seismic Acquisition Innovations

By Andrea Crook, P.Geoph. Over the past 10 years, land seismic acquisition has changed significantly. Nodal/cable-less systems have broadly replaced cabled systems, vibroseis sources have replaced explosive sources even in areas with difficult terrain, and high-density seismic programs are becoming commonplace. This article, based on the Chief Geophysicists Forum presentation “Top 5 Innovations in Geophysical […]

Land Seismic Acquisition Testing Strategies and Results – Southern Chad, Africa 2013-2015

By Andrea Crook, P.Geoph., Paul Stephenson, and Chaminda Sandanayake Over the past four years, Glencore has acquired four 3D seismic surveys covering 1200 km2, 216 2D seismic lines covering 4500 km and twenty-three seismic acquisition tests in Chad (Figure 1). Seismic acquisition testing provided tremendous benefit by improving subsurface imaging, increasing operational efficiency and reducing […]

Optimal Restriction Modeling

By Keith Millis, Case Caulfield, and Andrea Crook, P.Geoph. Restrictions to seismic acquisition increasingly limit the positioning of both sources and receivers at theoretically prescribed locations. Designing and subsequently repositioning station locations with respect to those restrictions has become an important and time-conscience aspect of both land and marine seismic programs. Historically, deviations from theoretical […]
