After developing an interpretation plan, the next step is to begin assembling the complete dataset. An inventory of available seismic data of all vintages is made, including ''p'' wave seismic, shear wave seismic, well data, velocity surveys, and VSP. The data are scanned for quality and suitability. At this point, a determination can be made whether the available data can reasonably support the goals of the project.

Available well, core, test, [[paleontology]], and [http://www.merriam-webster.com/dictionary/outcrop outcrop] data are gathered and organized for integration with the seismic data. Where available, [[gravity]] and [[magnetics]] data should be tied to the seismic data to identify the location of [[basement]], salt bodies, igneous intrusives, and shale masses. Another type of data that sheds light on the geological conditions of a specific reservoir is pressure and production history data. These data can provide information on the presence and proximity of faulting and the size of fault blocks.

If digital data are available, a decision must be made whether to use a workstation or proceed with a “paper interpretation.” Generally, a workstation offers the interpreter a valuable edge achieving a “correct” interpretation where detail is important (see [[Two-dimensional geophysical workstation interpretation: generic problems and solutions]]). For much regional work, paper is often still the most used medium due to the display limitations of the workstation screen. Seismic interpretations on paper, however, can always be digitized later for computer mapping or incorporation into a workstation project.
