Abstract
The inflow of fluid from an oil and/or gas bearing formation into an oil and/or gas production well is cyclically moved up and down along the length of an inflow region of the well by cyclically changing the opening of one or more control valves.
Claims6
A method for controlling fluid flow into an oil and/or gas production well by means of one or more control valves which control the inflow of fluids from the reservoir formation into one or more axially spaced areas of an inflow region of the well, wherein the opening of at least one of said valves is cyclically changed in accordance with a selected pattern which influences the inflow profile along the length of the inflow region such that an area of maximum inflow is created which cyclically moves up and down along the length of said inflow region wherein the opening of at least one of the inflow control valves is cyclically varied in a substantially sinusoidal pattern.
