Xodus Delivers Gas Modelling Suite for Australia's APLNG Project to Origin

Xodus Group announced Thursday that it has delivered a new Integrated Production Modelling simulation suite for Origin Energy to run complex scheduling scenarios for the Australia Pacific liquefied natural gas (LNG) project in Queensland, Australia.

Simulation experts in Xodus’ Perth operation carried out detailed modelling of both the compression facilities and the high pressure pipeline network. The work provides Origin, the upstream operator of Australia Pacific LNG, with the power to run detailed and fully automated operating scenarios through an intuitive user interface to accurately simulate the gas delivery network to maximize operating efficiency and manage delivery risks.

The team used AspenTech’s HYSYS steady-state linked with Microsoft Excel software to simulate several aspects of the project demonstrating novel and world leading simulation capabilities. A further scope of work involved the use of HYSYS dynamics to produce a hi-fidelity mimic of Origin’s centrifugal compressor control system to fully verify its design prior to installation. The value of both contracts was approximately $219,210 (AUD 300,000).

Andy Jones, general manager of Xodus in Australia said: “Xodus has a long history of building digital oilfield solutions for global clients; however the Australia Pacific LNG project required a forensic, in-depth knowledge of the inner workings of the simulation software in order to produce a bespoke solution. We used specialist programming techniques to achieve a complex model unlike anything that has been produced before. It allows Origin to run very detailed operating case scenarios to optimize operating conditions, balancing project critical factors such as power usage versus line pack availability.”

Xodus provides independent, integrated thinking to solve complex challenges. From field development planning to supporting asset integrity, operations and maintenance, the team works as trusted advisors at every stage of the asset lifecycle. The Perth based team is focused on helping clients to achieve operational excellence on new and existing assets.
