Legacy Application Enhancement at Shell Canada

Our Client

Shell Canada Ltd. – a subsidiary of Dutch-based Royal Dutch Shell – is one of the largest integrated petroleum companies in Canada.

Operating since 1911, Shell Canada is a leading manufacturer and marketer of refined petroleum products, extracting and distributing natural gas and natural gas liquids from wells across the country.

The Need

Being able to accurately predict deposition levels of elemental Sulphur in natural gas wells is key to avoiding damaging and/or plugging the wellbore, limiting production, and/or total well failure.

Using a simulation model to accurately predict the behavior of wells, and identify optimal production parameters and effective treatment applications, reduces risk and boosts performance.

Shell Canada’s simulation program, the Sulphur Modelling Application (SMA), was showing its age in terms of usability, performance, and sustainability. It was also out of date, not accurately reflecting revised understandings in reservoir engineering.

Quadrus was engaged to assist in redeveloping SMA into a more modern, sustainable application.

Case Study Enterprise, Shell SD

We’re extremely pleased with the solution. Quadrus understood our business needs and had a wealth of software and technical expertise to deliver in a cost-effective way.

The Solution

Applying their combined skills, Quadrus and Shell collaborated to analyze SMA and reverse engineer its logic and formulas. A thorough code review was also performed to understand how SMA should operate and identify any implementation gaps.

Based on the analysis, the primary goal became simplifying the application’s logic using object-oriented design principles to modularize the system and isolate the calculation engine from external interfaces.

Leveraging Quadrus’ expertise, the team quickly developed an enhanced version of SMA that combined the benefits of parallel computing techniques with up-to-the-minute industry knowledge.

The Result

The new solution expands the simulator’s functionality using state-of-the-art technologies to improve calculation performance, usability, and maintainability.

Its enhanced user interface and increased flexibility make it significantly easier to operate while simultaneously improving operator decision-making abilities. It also supports additional input sources and visualizations that increase efficiency, reliability, and general effectiveness.

With the new application’s increased ease of use and flexibility – along with its significant gains in calculation speed – Shell Canada technicians are better able to match the actual performance of each well with its forecasted production figures. Reservoir Engineer Scott Nieboer explains:

“We now have a technically robust, stable solution that expands our ability to improve how we work and how we operate our wells.”
