HYDROCARBON PRODUCTION USING MULTILATERAL WELL BORES

A system for producing a field having several reservoirs (10, 12, 14) and an aquifer (16) is described. Branch well bores (30) are drilled from the main well bore (2) towards the different reservoirs. One of the branches may contain a downhole separator for separating oil and water, the water being...

Summary:A system for producing a field having several reservoirs (10, 12, 14) and an aquifer (16) is described. Branch well bores (30) are drilled from the main well bore (2) towards the different reservoirs. One of the branches may contain a downhole separator for separating oil and water, the water being re-injected either into aquifer (16) or into the aquifer associated wrath the different reservoirs; another of the branches may contain a downhole separator for separating oil and gas, the gas being re-injected into the gas cap associated with the different reservoirs; another of the branches may contain a downhole storage device for storing chemicals for treatment against corrosion, scale, paraffin wax, hydrogen sulfide etc.; another of the branches may contain a unit for cracking and catalyzing the production fluids. Downhole flow control devices such as chokes may be located in the branch well bores the production of the different reservoirs being commingled in the main well bore.
