Practical utilization of actual treatment data is easy and can be utilized during or after the job. The advantage of using actual field data is that the user gains a better understanding of the well’s response to stimulation, helping facilitate the optimization of future treatments.
STIMPRO features advanced software technology and a multi-tasking architecture that provides the user with a responsive and flexible interface. The results can be displayed while the model runs in the background, giving the ability to produce reports and plots as the job is being executed. In addition to the skin evolution generated by the STIMPRO acidizing models, the software also has the unique capacity to continually monitor and characterize the ever-changing skin factor while the job is being executed.
There are three main operating modes in STIMPRO:
Acidizing Design mode allows engineers to quickly and efficiently generate a treatment schedule based on what the reservoir requires. After helping the engineer choose the appropriate fluids and acids for the type of damage that exists in the reservoir, STIMPRO will generate a pump schedule based on the reservoir penetration depth specified.
Acidizing Analysis mode is used before, during, and after the job once the treatment schedule has been determined. It is intended for detailed pre-treatment design and also for real-data analysis and history matching. The real-data analysis may be either in real-time, or post-job with previously acquired treatment data.
Production Analysis mode is used to predict or history match the production behavior of wells with or without matrix acid treatments wells. In this mode, STIMPRO passes the information from its acidizing model to the reservoir simulator where the effects of changing skin on well productivity are modeled. This is essential for evaluating success of past treatments and relevant economics of future treatments.
