About Halliburton

Halliburton Company is an American multinational corporation and the world’s second largest oil service company and responsible for most of the world’s largest fracking operations. The company helps customers maximize value throughout the lifecycle of the reservoir – from locating hydrocarbons and managing geological data, to drilling and formation evaluation, well construction and completion, and optimizing production throughout the life of the asset.

The Challenges

    Decision Space Nexus, provided by Landmark Graphics, is a next-generation reservoir simulation software suite. The Nexus development team did not fully embrace Agile development until they moved to a more structured Scrum environment. One of the most important lessons that the team learned on its own was the importance of having an automated regression test suite to exercise functionality under the graphical user interface (GUI)


Before any commitment was finalized, the development regression suite was run. In addition to the development regression suite, the team relied on a customer regression suite, a manual smoke test, and additional exploratory testing. The developer regression suite safety net paid off well for the team and they had general confidence in their check-ins. Despite the successful check-ins, the developer tests did not discover issues that were showing up in the more complicated customer models. To make matters worse, the massive challenge with the customer regression suite was that it took almost a week of computation time on a high-end cluster to determine if the tests passed or failed

In addition, slight perturbations in either data or algorithmic code or even running on a marginally different processing environment could produce inconsistent output results. Besides taking a long time to run, the problems discovered with the more complex customer data were also challenging to debug



The Solutions

  • Engineered and built custom TestArchitect technology to support for these custom controls.
  • Ported over 1000+ WinRunner test scripts from previous automation implementations on OpenWells Core.suite.
  • Focused on provided both reusability, low levels of maintenance and high degrees of test case design transparency.
  • Once the basic set of technology was implemented into TestArchitect, LogiGear began the process of reviewing, porting and implementing tests inside
    TestArchitect.

The Results

For the Classic OpenWells application, LogiGear was able to automate 1,095 test cases and find 241 bugs through the use of that automation. Both in build acceptance testing and subsequent test runs outside of the BAT. For the Rocket Project, LogiGear was able to automate 904 test cases, which resulted in 81 bugs that would have not been found otherwise through manual testing.

Halliburton was tasked with providing more releases to its OpenWells customers. They had been using WinRunner test automation for many years, and found it increasingly hard to scale especially when coupled with its lack of technology support for new OpenWells technology implementations. LogiGear was asked to provide a toolset and test design method using LogiGear’s product TestArchitect

You and the team are putting in a lot of extra effort running these two full OpenWells Classic regressions tests along with keeping up on new Rocket Test Case development ... and Halliburton has taken notice and appreciates this. I especially appreciate the way you have stepped in and taken over leadership of your team and the extra hours and effort you are putting in. Keep up the good work.
