Stochastic managing director Leo Mullins said the collaboration with ExxonMobil had continued for more than 20 years and that many other operators had also used his company's services.

Stochastic also recently launched the world's fastest reservoir simulation, ResAssure, and integrated asset modelling solution, GasAssure, working with operators and consultants in Australia, Europe, the Middle East and Asia.

The company provides specialist modelling software and services to the upstream oil and gas industry.

It customises solutions fit for purpose, readily maintainable and designed to be extended in a cost-efficient way to tackle additional technical issues as needs arise.
