Abstract: A method of integrated modeling using multiple subsurface models includes receiving multiple sets of input values associated with a hydrocarbon formation of the Earth. The method also includes receiving a network model that includes one or more assets configured to distribute a flow of hydrocarbons from the hydrocarbon formation to a processing facility. The method further includes generating the multiple subsurface models based on the multiple sets of input values, wherein each subsurface model comprises a set of input values of the multiple sets of input values, and wherein each subsurface model represents a production of the flow of hydrocarbons from the hydrocarbon formation. The method also includes applying the multiple subsurface models to the network model to generate an integrated model comprising multiple production rates of hydrocarbons via the one or more assets over time. The method further includes identifying at least one asset to adjust based on the integrated model.

Abstract: A method of modeling effects of operational procedures during startup of a fluid production or injection system at a field includes determining initial conditions of the field at a first time based on field measurements of the field. The method also includes simulating startups of the fluid production or injection system based on the initial conditions. The method further includes determining operational procedures for starting up the fluid production or injection system based on the simulated startups. The method also includes determining whether a startup command has been received. The method further includes sending instructions to startup the fluid production or injection system using the operational procedures when the startup command is received.

Abstract: A system includes a distributed control system and a subsea tree that includes subsea tree chokes and a subsea control module communicatively coupled to flow control valves. The distributed control system communicatively couples to the subsea control module, is located at a surface level, and includes processors that send a first instruction to the flow control valves to adjust hydrocarbon production flow when water or gas cut is above a threshold. The processors also send a second instruction to the subsea tree chokes to adjust the flow of the production when a quality of commingling of the production flow with additional production flows is less than a threshold, an arrival pressure is less than a threshold, or an arrival flow rate is less than a threshold. The processors further continue the production of the fluids with current settings when a production rate is above a production rate threshold.
