abstract = "The purpose of this book is to offer a mathematically well-defined unified framework to model sedimentary terrains. The core of this framework, named ‘GeoChron’, consists of a curvilinear coordinate system (u,v,t) which superimposes on the rectilinear coordinate system (x,y,z) commonly used to locate particles of sediment in the subsurface. For each particle of sediment observed today at location (x,y,z), coordinate (t) represents the geologicaltime (‘Chron’ in GeoChron) at which this particle was deposited whilst (u,v) represent the paleo-geographical coordinates (‘Geol’ in GeoChron) of this particle when it was deposited.

The u (x,y,z), v (x,y,z) and t (x,y,z) functions link the geological space (x,y,z), as it is observed today, to the depositional-space (u,v,t) and the ‘uvt-transform®’ thus defined plays a central role in using GeoChron to model the subsurface. In the (u,v,t) space, the image of each horizon is a horizontal plane where seismic attributes are easier to interpret and where reservoir properties are more accurately modeled.

The first part of this book is dedicated to a theoretical presentation of the GeoChron model. The second part presents applications of this model such as seismic interpretation, fault property modeling, fractured reservoirs characterization, geometrical uncertainties, property modeling, paleo-bathymetry estimation and permeability upscaling. To make this book ‘self sufficient’, the third part consists of annexes presenting the notions of tensors, differential geometry and Discrete Smooth Interpolation (DSI).",
