Abstract: A Distributed Framework Intertask Communication Method and Apparatus providing a method for communicating between applications using an extensible communication protocol with an intuitive user interface allowing the user to easily visualize and control the connectivity between applications. The user transmits an interest object associated with an event from a first application to a server. The server then retransmits that interest object to a second application. When the second application practices that event, information concerning the practice of that event is transmitted directly from the second application to the first application without routing that event information through the server.

Abstract: An operator sitting at a workstation views, on a display, a multitude of seismic traces having one or more horizons indicated therein by a plurality of sets of events (such as peaks or troughs or zero crossings) on the seismic traces. The operator uses a mouse to draw a line from left to right across a plurality of seismic traces being displayed on the workstation display screen. At this point, the line does not lie on the events (such as the peaks) of the seismic traces. Therefore, the line does not yet represent a horizon in an earth formation. The operator presses a key on the keyboard of the workstation. In response to the pressing of this key, the workstation processor executes a "snapper software" in accordance with the present invention.

Abstract: Formation tops correlation is interpreted between sampled log curves by a weighted combination of covariance, the ratio of standard deviation, and the ratio of summed amplitude. This covariance function is computed and evaluated appropriately for the geologic environment over a sliding analysis window. Correlations are determined for any number of wells and any number of events in each well. Geologic rules are used to establish a parameter for the algorithm operation and for the analysis of the resulting function. The geologic rules include bounding guide horizons, sequence rules, and a covariance cutoff parameter. Bounding horizons are picked from pre-existing seismic or geologic interpretations and from map grids. The rule set includes onlap, truncated, conformable, and unstructured sequence definitions. Additional geologic complexity such as crossover, repeat sections, and inverted sections are accommodated by the rule set.

Abstract: A processing system stores a special software known as the Cubemath software. The Cubemath software allows the processing system to process, analyze, and interpret a second set of seismic data relative to a first set of seismic data obtained from either a repeat seismic operation or a single seismic two processing method operation. A first set of 3D seismic data is collected at a particular location on the surface of the earth at time "t1", and a second set of 3D seismic data is collected at that same particular location on the surface of the earth (at a different time "t2" when the repeat seismic operation is being performed).
