The well system thereto comprises a plurality of entrance points at the earth surface and a system of underground wellbores which provide a subsurface connection between said entry points so that production of oil and/or gas can continue via at least one of said entrance points whilst equipment is moved into, through and/or from the well system via another entrance point.
