− | Data to the development geologist means many things. First, it means well data, including, but not limited to, well locations, header information (such as operator, year, total depth, status, elevation, and API gravity), deviation surveys, formation tops, fault cuts, results of drill stem tests and production tests, core data, and a host of calculated values such as isochore, true vertical depth, true stratigraphic thickness, and so on. Equal in importance is log information, including curves or traces, logging parameters such as mud type and resistivity, and analysis parameters such as formation water resistivity or cementation and saturation exponents. In some projects, surface geology is of great importance, consisting of bed attitudes and surface expression of contacts and faults. Seismic data can be critical, including time cross sections with interpreted horizons that need to be tied to the well control using an accurate interval velocity model. The geologist may also deal with periodic or cumulative production data by well, lease, or field. Also, the interpretation process generates new data elements, including zone average [[porosity]], net pay, and hydrocarbon pore feet. | + | Data to the development geologist means many things.

− | An enhancement to the menu approach is the graphical user interface, which combines text menus with graphical objects or icons to represent choices. Inherent with this method is consistency of design, so that the same type of function, such as editing, is always presented in the same place and the same way in all applications using the interface. These applications are also designed to share data, both text and graphics, among themselves. Also featured are standard methods for moving about within the data using scroll bars and consistent keyboard commands. Because of the graphical approach, even text-oriented applications such word processing present a what-you-see-is-what-you-get (WYSIWYG) display, incorporating font selections, character sizes, and even integrated graphics such as symbols and pictures. | + | An enhancement to the menu approach is the graphical user interface, which combines text menus with graphical objects or icons to represent choices.
