In the past few years there have been a number of software programs developed to process open hole wireline log data on personal computers. The majority require a thorough knowledge of program documentation to obtain the maximum benefit. When this is combined with the overall reluctance among many users to read documentation, the end result is a less than optimum utilization of processing power. The Microsoft Windows* operating environment for IBM compatible computers was created with the user's needs in the forefront by utilizing the concept of a "visual interface". Programs run under this environment can be executed with a minimum of keystrokes by using a mouse and pull down menus. All options are generally displayed to the user, and a minimum of program knowledge is required to execute an application in this system. To date, though, little use has been made of the Microsoft Windows operating environment in the log analysis software arena. To take advantage of the speed and ease of use, a popular minicomputer-based field log analysis program has been modified to function in the Windows environment. The Quick Log Analysis (QLA)" program is designed to accept the full range of wireline inputs available on the market. The Windows shell allows the user to run the program with a minimum of effort and a minimum of documentation. In addition, the Windows environment allows the user to integrate log graphics, cross-plots, reports, and text into a single document. The end result is a user-friendly log analysis program with powerful capabilities.
