It has long been the goal of the petroleum industry to use a hydraulic fracture simulator to provide on-site real-time hydraulic fracturing analysis. Now with the development of real-time fracture simulators and the power of portable computers this is a reality. This paper describes the use of a computer modeling system to accomplish this goal. A brief background of the theory behind real-data real-time fracture modeling as well as a description of the computer interfaces, data acquisition, and overall hardware requirements are presented. Case examples are included which show the benefits as well as the limitations of real-time fracture monitoring and analysis. Some suggestions on valuable data collection procedures are also discussed.
