S.M.A.R.T.S. Stimulation Monitoring and Reservoir Testing Software™ Fracturing Stimulation Mode Hydraulic Fracturing Monitoring and Analysis
Smarts32 is utilized by treaters and operators as their primary on-site monitoring system. The package not only allows them to view their raw input parameters, but a number of modeled parameters as well. Smarts32 is their digital window to the stimulation process. The user can take any of the raw input and modeled parameters and display them singularly or in combination with others, via custom graphs or custom digital text windows. Smarts32 allows the treater and operators to react to problems more quickly and allows engineering decisions to be made rapidly due to its quality of data gathering and presentation. Smarts32 can be run on simple laptop systems as well as systems that support multiple video outputs. It provides many of the calculated and modeling capabilities during the stimulation process. A few are listed below.
Design versus actual staging information and surface and downhole job totals.
Hydrostatic calculations and friction profiles based on fluid front tracking.
Bottomhole pressure (BHP) modeling for non-energized as well as energized fluids.
Position of top and tail of all stages within the treating string.
Energized fluid (foam) modeling for N2, CO2, and binary systems with surface and downhole foam modeled parameters presentation.
Fracture net pressure profiling.
Optional real-time fracture geometry presentation (Smarts32 versions 3.17cIP2 and above).
Pre-frac testing modes available at anytime during the monitoring phase (see Pre Frac category).
Numerous report generations of the monitored and modeled parameters.
The treater is provided a unique screen just for their use.
From this window, all Smarts32 capabilities can be activated via menu and special speed button selections. The lower right quadrant plot can be toggled to any of the canned and custom screens that the user desires to see. Many other full screen displays are available such as the wellbore screen, which displays surface and downhole parameters along with treating string displacement information.
If the job is energized or a foam job, this screen will automatically add gas related parameters for viewing.
A number of standard text and plots exist. A few are presented below. An example of a simultaneous parameter plot is presented below.
The following is a job totals window.
The following is an example of a custom text screen that the user created concerning averages.
The following is a custom plot screen that the user created with foam information.
The following is an example of a window in which the user can view all the raw channels as they are received.
A full screen window can be created for all of the text and plot screens. These screens are also sizable. The following is a staging screen that compares design versus actual volumes. The lighter grey bar is the designed stages volume. The overlaying color bar is the actual. The bar graphs to the far right present a fluid and solids comparison for the current stage. If one is ahead of the other, that parameter is ahead of design objectives for that stage.
Some of the job reports are as follows. Some of these can be user generated during the actual monitoring or replay session. These reports are automatically dropped into ASCII files for easy viewing with editors and import.
Next is an example of an all stages report.
Below is an example of an end of stage report.
Presented below, are some of the other end of job reports, some specific to foam.
Presented below is an example of a datalist file that Smarts32 generated during monitoring. The user defines the derived channels and their order to be printed to the file. The user also defines how often a row of new data is to be printed to the file. This allows the user to create an ASCII file on the file of just the operator’s desired parameters.
All user actions and user comments are also recorded to a comment report file. It is as follows.
This comment report is tagged with the received clock time from the input stream as well as the P.C. clock time.
Last of all is an example of a real-time fracture geometry screen that will be available in Smarts32 versions 3.17cIP2 and above by late fall 2009. Many other features exist that are more fully discussed within the user manual.
