Abstract: A method for risk mitigation comprises calculating on at least one processor, a likelihood of occurrence for a risk event, a degree of disruption for the risk event and a disruption time for the risk event. Each risk event is in a list of risk events. The likelihood of occurrence is based on a frequency of risk of the risk event. The degree of disruption is based on a severity of risk of the risk event. The disruption time is based on a duration of restoring an asset to a condition prior to the risk event. A value at risk based on the likelihood of occurrence, the degree of disruption and the disruption time is determined for the risk event. A mitigation action is determined to reduce the value at risk. An indication of the mitigating action is presented on a user interface.

Abstract: A numerical procedure is disclosed to improve the prediction of heat fronts when simulating hot fluid injection in viscous hydrocarbon reservoirs. The mathematical model is composed of the conventional governing equations that describe multiphase fluid flow and energy balance. The reservoir geometry can be partitioned into a regular Cartesian grid or an irregular corner-point geometry grid. The numerical procedure uses the finite different (FD) method to solve the flow equations and the discontinuous Galerkin (DG) method to solve the energy balance equation. The proposed FD-DG method is an alternative to the traditional solution procedure that uses the FD method to solve both the flow and the energy equations. The traditional method has the deficiency that it may require excessive number of grid cells to achieve acceptable resolution of the heat fronts.

Abstract: An improved technique involves providing application workload simulation capability via a centrally located synthetic data generation service to an external party. Along these lines, a client inputs a description of an application scenario into a web form which sends a request to a central server to generate a synthetic data simulation program. The central server extracts parameters values from the request corresponding to the application scenario and finds a model in a model database based on the parameter values. From the model, the central server derives a Java program that generates synthetic data for simulating the operation load of the application scenario described by the client, and sends the Java program to the client. The client is then able to generate synthetic data using the Java program on various configurations to determine which will successfully handle the synthetic data load continuously over a given period of time.
