Fundamentals of geophysics

Reservoir geophysics

The concept of petroleum reservoir geophysics is relatively new. In the past, the role of geophysics was largely confined to exploration and, to a lesser degree, the development of discoveries. As cost-efficiency has taken over as a driving force in the economics of the oil and gas industry and as major assets near abandonment, geophysics has increasingly been recognized as a tool for improving...

Success with Geophysics: Archaeology

Ground-penetrating radar (GPR) has recently gained a wide acceptance in the archaeological community as a method to quickly and accurately locate buried archaeological features, artifacts, and important cultural and geological strata in the near-surface. The GPR method has now become one of the primary tools for geophysical feature identification primarily because of its three-dimensional abili...

Turbulence in Geophysics

Fluid in Geophysics including atmosphere and ocean, compared with the normal fluid in Hydrodynamics, its properties, such as density, pressure, temperature and velocity, all change along with altitude. That is to say, fluid in Geophysics is stratified. Therefore, the characteristics of its turbulence at different stratifications will not be the same, either. Some special characteristics, as wel...

Evolving Geophysics Through Innovation

Continuity along reflectors in seismic images is used via Curvelet representation to stabilize the convolution operator inversion. The Curvelet transform is a new multiscale transform that provides sparse representations for images that comprise smooth objects separated by piece-wise smooth discontinuities (e.g. seismic images). Our iterative Curvelet-regularized deconvolution algorithm combine...
