Integrated Asset Management (IAM) workflows integrate subsurface reservoir models and surface production networks, allowing engineers to bring under control the rapidly expanding asset complexity due to increasing amount of captured data. While consolidation of acquired & processed data continues to improve, IAM Workflows continue to face problems with providing an integrated platform for dynamic reservoir simulation models and surface facilities.
Modern DOF systems can’t survive without comprehensive solutions that provide an all-in-one outlook for assets’ performance for management. State-of-the-art systems are required to address operational challenges, perform root-cause analysis, identify bottlenecks and understand system limitations. Furthermore, high-end modelling is must to effectively quantify the plethora of data collected over the field.
Modern IAM workflows may be classified into several types, depending on how the subsurface modelling applications talk to the surface network systems, be it in terms of automation, types of coupling or level of interface.
Flow Table Coupling
Flowing bottom-hole pressure (BHP) is used as a function of flow rate for several parameters like wellhead pressure, gas-oil ratio, pressure-volume-temperature, etc. for well models. The information is stored within tables that capture liquid rate changes with pump frequency. Simulators are designed to use each table during the well’s life span or until the event is completed. While the simulator can run instantly, accuracy is sacrificed.
Static Coupling
A prior generation of reservoir performance tables are used for this workflow, comprising of oil, gas and water production rate forecasts over the set time horizon. The following diagram shows a workflow using static coupling, and while it is less accurate than dynamic coupling it is quite popular among operators.
And this is just the tip of the iceberg!

Are you overpaying for your oil & gas SCADA system?
Would it be helpful to combine the production data from your Oil and Gas SCADA System with all the production reports, downtime events, well tests, and run tickets from your Pumpers into one centralized place from which your entire team could work?
If so, check out ElasticOps to see how hundreds of Operators (and thousands of Pumpers) are bringing their oilfield automation, oil and gas monitoring, and pumper production reports – all underneath one umbrella.
