2017 SPE Canada Unconventional Resources Conference

Last week, February 15-16, 2017, I attended the 2017 SPE Canada Unconventional Resources Conference, and I presented SEP 185029 “Depth-of-Investigation and Volume-of-Investigation Calculated from Fracture-Injection/Falloff Test (DFIT) Data.” The conference seemed well attended, and although I was suffering from a bought of the flu, I was able to complete the presentation without exposing too many colleagues to Influenza A.

DFITpro programming has been proceeding, but I ran into some problems that Microsoft Azure engineers are trying to help me resolve. I added the user database to the software to allow users to log into the site and view the DFIT analysis workspace and example problems. As these things always seem to go, it worked perfectly on my local development environment, but when I deployed the solution to the cloud, the database deployment failed. I am working with Microsoft Azure engineers, and we will find a solution to the user database issue soon.

The good news is that I am continuing with the development of the DFITpro user workspace. I’m attaching a screenshot below that shows the work environment for DFITpro once a user has logged into the site. Over the next week or so, I’ll be adding the example problems so registered users can start to see how the data, input screens, and graphics work. Hopefully, user data analysis will be available soon after the example problems are posted.

Once a user is able to log into DFITpro.com, a menu will be displayed at the top of the workspace with options for DFITpro / Multifrac ProD / Wellbore FloD (see Figure 1). DFITpro is, of course, the DFIT analysis module, and when DFITpro is selected, the bottom image (Figure 2) shows the workspace. On the left side of the browser window are selections for particular tasks to be completed, and a menu of available data sets will be displayed for users that have analyzed multiple data sets and saved the data in the cloud. Across the top of the browser workspace window are tabs for the steps in an analysis, and tabs are selected and completed left-to-right in the DFIT analysis workflow.

Other options include Multifrac ProD, which is a multifractured horizontal well diagnostic and flow module for the analysis of production data, and Wellbore FloD, which is the wellbore flow model for calculating flowing bottomhole pressures from surface production measurements. Multifrac ProD and Wellbore FloD will be added after the DFITpro module is complete, but all three modules will provide a fairly robust cloud-based analysis tool for multifractured horizontal wells.

Thank you for being patient as DFITpro.com has been developed. With the removal of a few more bugs, visits to DFITpro.com will much more productive as users are able to upload and analyze data.
