The instructor will show how to use this tool and its applications in exploration geophysics and explain all methods and options available. Areal extent estimation offers valuable data for designing a 3D/2D surveys. Areal extent is also important for designing processing flow for 3D seismic surveys. Discuss how it helps the processor/interpreter in QC processing of 3D data, and the interpreter can use the areal extent to QC processed 3D seismic data interpreted structure maps. Discuss the use of linear vs. nonlinear ray tracing. Show how the velocity gradient impacts linear to nonlinear ray tracing. Demonstrate how to select parameters for parametrically modeling a structure, carry out ray tracing and subsequently generate migrated and un-migrated structure maps, dip, and strike maps. The instructor will explain how to use existing structure data from interpreted maps or well data as x, y, z coordinates in excel worksheet for input to ray tracing, and generate migrated and un-migrated maps, 3D dip maps, strike maps and curvature maps. The instructor will lead the participants in saving graphics images generated during ray tracing and show how to export saved images and individual maps from saved SurferTM files to Powerpoint presentation and to a Word document for writing reports.

The instructor will show how to use this tool and its applications in exploration geophysics and explain all methods and options available. This tool helps in understanding the seismic data acquisition footprints with the use of modeling, analysis, and removal of unwanted footprints. Discuss how it helps the processor/interpreter in QC processing of 3D data for AVO. Using this tool, the participants will model the acquisition footprints, scale factors and AVO. Subsequently, using this model data carryout a step by step analysis with each method for footprint removal and AVO extraction in this tool resulting in comparison of extracted AVO and the actual AVO response. The instructor will show how to prepare seismic data for input as Excel worksheet. Participants will also perform a preliminary AVO modeling and analysis with results presented in Excel Worksheets, and work with optional use of scaling factors such as, spherical divergence, reflection transmission losses, and attenuation. Participants will save screen images as graphics files, export the saved images to Powerpoint presentation and to a word document for writing reports.

This is a tool for organizing Worksheets generated with Mathcad and Excel and other Worksheets generated with other applications. The instructor will review each of the following Databases: (1) SurveyDesign; (2) DataProcessing; (3) AVO; (4) Attributes; (5) InterpretationTools1; (6) InterpretationTools2; (7) Well Logging; (8) PetroPhysics; (9) Geology; (10); Engineering; (11) User Applications. The instructor will briefly review the Mathcad worksheets (72) and Excel Workbooks (98) included in the GPGToolBox. Mathcad worksheets and Excel workbooks cover topics in 2D ray tracing modeling for flat layers, AVO modeling (using Zoeppritz), 4D reservoir monitoring, Thin sands thickness estimation, frequency absorption, and many other topics in most of the 11 sections listed above. Some of the Mathcad worksheets and Excel workbooks are duplicated under Engineering, and a few other sections as place holders. The instructor will demonstrate and lead the Participants in deleting, editing, and adding files into the database for GPHToolBox for convenient and quick access to the workbooks or worksheets entered into the database.
