|Composite well image from log data: technology of creation and application|
|By analogy with method of the composite photo portrait, propose to create a generalized image of a certain set of wells from their log data. Superposition of individual wells is performed on the base of the correlation model, which allows to form a set of stratigraphically equivalent points. The construction of a stratigraphic model is considered as the solution of a multidimensional optimization problem. The composite well pattern allows quantifying the typical characteristics of formations and stratums and analyzing the individual deviations specific to individual areas or wells. Based on this approach, it is possible to predict the distribution of properties for the projected wells and create three-dimensional models (cubes) of properties of the studied objects.
Keywords: automatic correlation of wells, well log data, composite portrait method, composite well, forecasting section of wells, cubes of properties.
