The document describes a case study on functional testing for a well log digitization tool developed for a client in the oil and gas industry, which faced challenges in accurate classification, quality control, and user interface design. Contata Solutions implemented a two-phase testing process, addressing performance optimization and ensuring the functionality of the tool amidst the complexity of various well log types. The project highlights the need for specialized expertise and the shift from pixel-based to depth-based digitization methods.
Functional Testing for a Well Log Digitization Tool
- 1. CASE STUDY Functional Testing for a Well Log Digitization Tool OVERVIEW The client specializes in providing global geoscientific data products and services to the Oil & Gas industry. Additionally, they offer advanced, permanently-installed reservoir monitoring solutions on a global scale. The client possesses the industry's largest online well data collection, covering areas in North America, South America, Europe, Russia, and Africa. CHALLENGES US: +1-612-977-1700 www.contata.com [email protected] The client's existing setup posed several challenges, including: • Accurate classification and digitization of oil and gas well logs. • Incorporation of digitization, editing, and quality control (QC) features within a unified tool to ensure correctness and quality verification simultaneously. • Implementation of a split-screen feature to facilitate user-friendly work on multiple off-scale graphs. •Oil & Gas INDUSTRY •Functional Testing SERVICES •.NET 4.0 •WPF •MVVM TECHNOLOGY • LAS import and conversion capabilities for the internationalization of digitized oil and well logs. • Auto-trace functionality for automatic tracing of logs based on specified inputs.

US: +1-612-977-1700 www.contata.com [email protected] • Increased cost efficiency • Reduced human dependency, minimizing risk of human error • Internationalization of logs achieved through LAS converter. • Performance optimization BENEFITS US: +1-612-977-1700 www.contata.com [email protected] The application, being highly domain-specific, demanded specialized expertise due to the extensive variety of oil and gas well logs. Also, the tool's compatibility with each log type presented a significant challenge. Complex analytics and calculations were involved in the data digitization process, requiring an understanding of geological formulas to assess correctness. The digitization approach shifted from pixel-based to depth-based (curve on the raster) at a later stage, complicating the identification and verification of impacted functionality. Testing also faced challenges, including the selection of eligible logs for test data preparation to maximize coverage in minimal time. Contata carried out the testing in two phases. Phase I involved functional testing to verify various tool features developed for the client, along with multiple regression cycles to confirm fixes. Performance issues were identified and reported to the development team. Phase II encompassed a comprehensive reevaluation of the entire application from both functional and performance perspectives.
