The Petroleum Engineering & Management Corp software program “PEMCoDcl” is a stand-alone program used to quickly evaluate oil and gas properties and combine results for a large number of wells. The program is designed to plot production data, make forecasts and compute economics using decline curves and other methods. In addition, curves may be digitized directly on the graph. The production data and forecast may be used independently or in conjunction with economics. All the data for a given project can be edited and updated on the screen similar to a spreadsheet.  When updated, the program provides a quick up-to-date reference for engineers and others. Property numbers lists are used to group the wells. Both producing and injection wells, and both daily and monthly volumes are handled. Copies of graphs and tables may be printed directly with the program for ready insertion into engineering or other reports.

To begin, production data files are placed in a project folder. A file entitled 'PrLst-ALL", is generated each time the program is run.  This file contains a list of all the production data files in the project folder and all property lists and totals that may have previously been created. When a property is selected from the file list window it is plotted as shown in the decline curve window. A forecast for each well in the active list may be generated by clicking the button entitled 'Auto Computer Fcst'. In some cases, for example inclining production or zero production for the last date in the production file, etc, a forecast  is not automatically generated. In these cases a forecast is made by selecting a product option (oil, gas, or wtr) and one of the other available options (equation, computer generate, dgtz, etc.) in the decline curve window.
