3-D seismic data have become the key tool used in the oil and gas industry to understand the subsurface. In addition to providing excellent structual images, the dense sampling of a 3-D survey can sometimes make it possible to map resewoir quality and the distribution ofoil and gas. The aim of this book is to help geophysicists and geologists new to the technique to interpret 3-D data while avoiding common pitfalls
Topics covered include basic structural interpretation and map-making; the use of 3-D visualisation methods; interpretation of seismic amplitudes, including theirrelation to rock and fluid propertiesi and the generation and use of AVo and acoustic impedance datasets. Also included is the increasingly important neld of timelapse seismic mapping, which allows the interpreter to ftace the movement of fluids within the reservoir during production. The discussion of the acquisition and processing of 3-D seismic data is rntended to promote an understanding of important data quality issues. Extensive mathematics has been avoided, but enough detail is included on the effects ofchanging rock and fluid properties to allow readers to make their own calculations
The authors ofJ-D Seismic Interpretation are professional geophysicists with many years, experience in the oil industry. They are still actively inter?rcting 3-D seismic data and arc thercfore able to summarise the current best practice. The book will be indispensable for geoscientists leaming to use 3-D seismic data, particularly $aduate students of geophysics and petroleum geology, and new enftants into the oil and gas industy.
If you want to find oil and gas accumulations, or produce them efficiently once found, then you need to understand subsurface geology. At its simplest, this means mapping subsurface structure to find structures where oil and gas may be trapped, or mapping faults that may be barriers to oil flow in a producing field. It would be good to have a map of the quality of the reservoir as well (e.g. its thickness and porosity), partly to estimate the volume of oil that may be present in a given trap, and partly to plan how best io get the oil or gas out of the $ound. It would be better still to see where oil and gas are actually present in the subsurface, reducing the risk of drilling an unsuccessful exploration well, or even following the way that oil flows through the reservoir during production to make sure we don’t leave any more of it than we can help behind in the ground. Ideally, we would like to get all this information cheaply, which in the offshore case means using as few boreholes as possible
