PROCESS MODELLING OF ROCK SAMPLE HANDLING IN PETROPHYSICAL LABORATORY

Everyday procedures carried out in petrophysical laboratory can be defined as a complete cycle of business processes. Sample handling process is one of the most significant and demanding procedures. It starts with sample receiving in laboratory and then subsequently, series of analyses and measurements are carrying out resulting in petrophysical parameters. Sample handling process ends with sample storage and archiving of obtained measurement data. Process model is used for description of repeating activities. Sample handling process is presented by graphical method and use of eEPC diagram (extended Event-Driven Process Chain) which describe process based on events. Created process model jointly binds static laboratory resources (measuring instruments, computers and data), speeds up process with increasing the user’s efficiency and with improvements of data and information exchange. Besides flow of activity, model of data sample handling includes information about system components (laboratory equipment and software applications) that carry out activities. Described model, with minor modifications and adaptations, can be used in any laboratory that is dealing with samples.
