Wolfram Language: Improving Online Monitoring of Subsea Pipelines

Eric Smith
Organization: Wood Group Kenny

Wolfram Technology Conference 2015
Conference location

Champaign, Illinois USA

Traditional monitoring systems in the oil-gas industry are built from the ground up in Fortran, C#, and other compiled languages. The development time for advanced numerical applications are long and often not as reliable as those found in the Wolfram Language. Additionally, tolerances in the industry are decreasing and operators are demanding higher fidelity models. The Wolfram Language is being integrated with existing compiled code to give more reliable numerics, more precise models, and substantially shorter development times. This presentation will discuss how conformal mapping and NDSolve is being used to improve thermal modeling of partially buried subsea models. Using Enterprise CDF, Wood Group Kenny’s Virtuoso software is able to integrate the multiphase fluid dynamic simulation with a pseudo-3D soil model solved by NDSolve. Conformal mapping of the domain into bipolar coordinates creates a grid that efficiently resolves the high gradient areas of the domain. This eliminates the need for mesh generation, though that option is being investigated since the release of Mathematica 10. Numerical stability is an issue modelers have to be constantly wary of when configuring Virtuoso. However, when using the Wolfram Language, NDSolve dynamically changes the time step so convergence testing is unnecessary lending confidence to the model and decreasing validation efforts. The Wolfram Language is significantly reducing the numerical challenges that plagued the development cycle in the past.
