Abstract: A modular tubular system is assembled of a tool handling section and a tubular section. The tool handling section may be made of a material that is suitable for handling by conventional tubular handling tools, such as conventional steel. The tubular section may be made of a different material with desired properties for special applications in a well, such as aluminum, titanium, nickel, or stainless steel alloys, or composite materials.

Abstract: A downhole gas-liquid separator (10) separates a gas from liquid in a well, with the liquid being pumped to the surface. The separator includes an outer tubular housing (12) and an inner flow tube (41) for passing the liquid phase to the surface after separation. In one embodiment, a spiral gas separator (32) imparts a helical flow to assist in separation of the gas from the well fluids. Gas from the separation chamber flows upwardly through a gas riser (25) to a downcomer (28), and then downwardly through the downcomer (28) to one or more gas vents (16) in the outer tubular housing (12). The gas riser and downcomer act as a liquid trap to exclude liquids in the annulus surrounding the tool to enter through the gas vents (16).
