Abstract
An oil and gas network comprises multiple branched flow paths, such as in multi-zonal wells and/or multibranched wells and/or networks including multiple wells, and multiple control points at different branches, wherein the multiple control points may include multiple valves and/or pumps for controlling the flow rate through respective flow paths of the multiple branched flow network. The network is modelled to model the variation of one or more flow parameter(s) in one or more flow path(s) of the network. A method for this modelling includes: generating a long-term model using a first set of data relating to measurements of the flow parameter(s) and the status of the control points over a first period of time, wherein the long-term model describes the relationship between flow rates, the status of control points, and measured flow parameters including pressure and/or temperature; generating a short-term model using a second set of data relating to measurements of the flow parameter(s) and the status of the control points over at least one second period of time, wherein the at least one second period of time is shorter than the first period of time, and wherein the short-term model…
