Sparse 3D, what’s in a name?

Jack Bouska

…Recent technical innovation associated with sparse 3D design has resulted in acquisition costs that are substantially lower than both traditional 3D and comparable 2D seismic acquisition expenditures. The Sparse 3D cost/sq. km. price breakthrough has allowed Amoco Canada to pursue Devonian play trends into operationally difficult, heliportable, foothills terrain by…

Deep Sea Gas Hydrates: The Energy of the Future? Deep Sea Studies off Vancouver Island

Roy D. Hyndman

…New clean energy sources and global climate change are subjects of much recent discussion. Naturally occurring gas hydrates containing methane may play an important role in both subjects. Hydrates are solid ice-like substances consisting of rigid water molecule cages stabilized by enclosed gas molecules, notably those of hydrocarbons. Gas hydrate…

Methodology for Seismic Inversion, A Western Canadian Reef Example

John V. Pendrel and Paul Van Riel

…Abstract Modern seismic inversion methods model both wavelet amplitude and phase effects and offer the opportunity for improved resolution and presentation of data in a form immediately recognizable to both geophysicists and geologists. This has re-focused our attention to the problem of non-uniqueness. Since the bandwidth of the seismic data…

Multivariate Geostatistics

Brian Russell and Dan Hampson

…1.0 Introduction Multivariate geostatistics is a broad term that encompasses all geostatistical methods that utilize more than one variable to predict some physical property of the earth. Bivariate geostatistics is obviously the simplest subset of the multivariate techniques and thus the standard technique of cokriging could be called multivariate geostatistics.…

Whither Seismic Imaging?

Samuel Gray

…Abstract Seismic imaging has evolved to the point where, with sufficient knowledge of the propagation velocities, we can now obtain accurate images, before stack in three dimensions, of almost arbitrarily complicated geologic structures, and we can do this at reasonable cost. That is not to say that we can close…
