Abstract
A chronostratigraphic database comprising a plurality of discrete data points, wherein each data point comprises an x, y, z and T value, wherein x, y, and z are Cartesian coordinates describing a position and T is a geologic time event relative to said position; a method to produce a chronostratigraphic database and to utilize the database; and a modeling system wherein the database includes data formatted and arranged for use with a computer-implemented method or web-based method for controlling serving of an advertisement or public service message using its relevancy to a request.
Claims20
A chronostratigraphic modeling system comprising a database comprising a plurality of surface data points, each comprising well-log data, wherein each of the surface data points are associated with a plurality of discrete subsurface data points representative of the depth of a corresponding data point from the surface and optionally one or more additional attributes associated therewith, each depth data point including an age correlation attribute tag (T) representing a numerical geologic age of the stratum at a depth identified by the particular data point, the numerical geological age correlation being based on a plurality of data points obtained from a plurality of individual well logs across a portion of a basin, one or more basins, or a combination thereof, wherein the database is computer searchable upon a user request by the numerical geologic age attribute in combination with one or more spatial coordinates, and optionally in combination with one or more of said additional attributes.
A chronostratigraphic modeling method, comprising:
- receiving a request from a user and searching a computer searchable database by a numerical geologic age attribute in combination with spatial coordinates, and optionally in combination with one or more additional attributes, and displaying the selected data points in an isochron selected from points, lines, grids, surfaces, volumes, or a combination thereof,
- the computer searchable database comprising a plurality of surface data points each comprising well-log data, wherein each of the surface data points are associated with a plurality of discrete subsurface data points representative of the depth of a corresponding data point from the surface and optionally one or more additional attributes associated therewith, each depth data point including an age correlation attribute tag (T) representing a numerical geologic age of the strata at a depth identified by the particular data point, the numerical geological age correlation being based on a plurality of data points obtained from a plurality of individual well logs across a portion of a basin, one or more basins, or a combination thereof.
A method to produce a chronostratigraphic database comprising:
- a) scanning a plurality of well logs to create raster images;
- b) digitizing the raster images to create digitized well log data;
- c) normalizing the digitized well log data to remove outlier data or errors in the data recording process;
- d) scaling the normalized digitized well log data according to markers across multiple digitized well logs;
- e) correlating the normalized digitized well log data to identify numeric geologic age markers in each depositional stratum;
- f) tagging each data point with an age correlation attribute (T) representing a numerical geologic age of a particular stratum at a depth identified by the particular data point, the numerical geological age correlation being based on a plurality of data points obtained from a plurality of individual well logs across a portion of a basin, one or more basins, or a combination thereof;
- and
- g) storing the digital data in a computer searchable database format to form the chronostratigraphic database.
