Roxar rolls-out new Tempest simulator

A new release of fluid flow simulator includes dual porosity computations for naturally fractured reservoirs.

Roxar has announced a new release of its Tempest reservoir simulation package. Tempest 6.2 now includes a novel technique for simulating fluid flow in naturally fractured reservoirs. The new single grid, dual porosity technique halves run times compared to conventional dual porosity models. A new ‘tensor permeability’ option is now used to describe complex heterogeneous reservoir systems, especially when dips do not conform to grid coordinates.

Tempest now runs on both 64 bit Linux and Windows 64-bit as well as Unix. The state-of-the-art simulator engine is coded in C++ with a Java-based user interface. Tempest models a range of physical processes within a single application including black oil, compositional, dual porosity, steam, coal bed methane and polymer injection. Tempest can also act as a companion package to Roxar’s flagship Irap RMS modeling suite, reducing workflow complexity.


Roxar CEO, Sandy Esslemont said, ‘As industry focuses on reservoir management and production optimization, the need for a modern, fast, easy-to-use simulator that scales to the users’ needs, has become a critical success factor. Our proven track-record with high-profile customers such as Lukoil and our commitment to support means that Roxar’s clients will achieve greater understanding of their reservoirs and maximize reservoir performance for years to come.’ Reservoir engineers can also take advantage of Irap’s new engineering-focused capabilities such as fault-seal analysis and fracture modeling techniques, bridging the gap between geological and reservoir engineering workflows.
