General Information About the Review
The «SIAM Welltest» complex IT system was tested at the premises of "Gazprom Neft Science and Technology Center" in April 2019.
Experts
The reviewers were two experts from the department of scientific and methodological support for development and professional growth of Gazpromneft STC LLC: V.A. Mazhar and V.S. Kotezhekov.
Testing Stages
The system was tested in two stages. First, an analysis of filtration model accuracy was conducted in comparison with «Ecrin Saphir». In the second stage, the available functionality for modeling and interpretation of pressure transient analysis was analyzed.
First Stage Results: Filtration Model Accuracy
During the first stage, good convergence of indicators relative to the standard sample was achieved:
"Analyzing the process of model curve loading, a quite convenient and clear interface of the «SIAM Welltest» complex IT system can be mentioned. It should be noted that the functions of this complex IT system approximate those of «Ecrin Saphir». The diagnostic models of filtration, and the determined reservoir and skin zone characteristics, are fairly close to the standard."
Second Stage Results: Strengths and Weaknesses of the Functionality
When analyzing the functionality of the application, some advantages as well as areas for improvement were identified. Functions such as the ability to model well interference and auto hydraulic-fractures were noted as distinctive characteristics. As for drawbacks, the absence of numerical and nonlinear modeling was noted. The inability to integrate «SIAM WellTest» with «Ecrin Saphir» was described as one of the main disadvantages:
"The inability to integrate «SIAM WellTest» with «Ecrin Saphir» work files, such as opening/saving files, should also be noted. This fact complicates the possible integration of «SIAM WellTest» into Gazprom Neft's industrial processes."
Review Outcomes
As a result of the tests conducted, a number of positive qualities of the «SIAM WellTest» software product were noted. The application developers were also assigned a number of tasks related to improving the interface, functionality, and compatibility with other products noted in this review.
