Abstract: A system for assisted performance of repetitive functions within a service engagement provides platform for storage and execution of processes and corresponding data. The platform includes libraries for storage of application packages, assets and artifacts. Application packages, assets and artifacts from within the library can be associated with engagements to provide models of the engagement and perform functions necessary in the course of the engagement. The assets and artifacts can be repetitively used by various application packages and other assets in order to achieve the various objectives of those application packages.

Abstract: The invention utilizes 3-D and 4-D seismic surveys as a means of deriving information useful in petroleum exploration and reservoir management. The methods use both single seismic surveys (3-D) and multiple seismic surveys separated in time (4-D) of a region of interest to determine large scale migration pathways within sedimentary basins, and fine scale drainage structure and oil-water-gas regions within individual petroleum producing reservoirs. Such structure is identified using pattern recognition tools which define the regions of interest. The 4-D seismic data sets may be used for data completion for large scale structure where time intervals between surveys do not allow for dynamic evolution. The 4-D seismic data sets also may be used to find variations over time of small scale structure within individual reservoirs which may be used to identify petroleum drainage pathways, oil-water-gas regions and, hence, attractive drilling targets.
