Publication number: 20230167717Abstract: A method of modelling one of a plurality of hydrocarbon production wells, wherein each production well is associated with at least one control point in a flow path associated therewith. The method comprises: (i) generating a first model capable of describing for any one of the first plurality of production wells a relationship between flow parameters, well parameters and/or an associated status of the at least one control point, wherein the first model is parameterised by a set of first parameters representative of properties common to all of the first plurality of production wells. The model can be applied to estimate well parameters, flow parameters and/or the status of control points. In addition, the resultant models can be used to optimise production of the production well.Type: ApplicationFiled: April 8, 2021Publication date: June 1, 2023Applicant: SOLUTION SEEKER ASInventors: Vidar GUNNERUD, Anders SANDNES, Bjarne GRIMSTAD

Well testing apparatus and methods for measuring the properties and performance of oil and gas wells
Patent number: 9612360Abstract: To determine properties of multiple oil and gas wells, oscillations at different test frequencies are applied to the flow rate and/or pressure of multiple wells. Measurements of flow rate and/or pressure and temperature in flows downstream of a production header of the multiple wells are then obtained. Such measurements from the flows of the multiple wells are subjected to a frequency analysis of the pressure, flow rate and/or temperature measurements to determine pressure, flow rate and/or temperature variations induced by the applied oscillations. Properties of the different wells of the multiple wells based on the results of the frequency analysis are thus determined.Type: GrantFiled: November 16, 2012Date of Patent: April 4, 2017Assignees: NORWEGIAN UNIVERSITY OF SCIENCE AND TECHNOLOGY (NTNU), SINTEF TTO ASInventors: Federico Zenith, Johannes Tjønnas, Ingrid Schjølberg, Bjarne Foss, Vidar Gunnerud -
