While digitizing, Plan graphs contours, faults, sink holes, and well locations. Plan can be used with a variety of digitizing tablets connected to the computer through a serial port. Once a map is digitized and saved, it can later be reloaded and contours edited. Once a map has been defined, Plan presents two tables. One table gives the areas of each contour value and the second gives the volumes by the user-selected volume methods.
Users specify the top layer, delta h, to define peaks for the volume calculation.
Reserves can be calculated in Plan from user defined parameters for volume, porosity, hydrocarbon saturation, formation volume factor, and recovery factor. Users can select which volume methods to display. A report summarizing the results can be printed. This report includes the map, area and volume tables, reserve calculation if done, and information about the analysis provided by the user. Plan adds map files to compute areas and volumes for over-sized maps digitized in parts.
