Hydrocarbon fluid production wells and similar process flowstreams have a spiral baffle-type separator interposed in a surface flowline for separating fluids of different densities, such as gas from oil or gas from oil and from water, for example. Particulate solids may also be separated from the fl ...

Oil and gas are separated downhole in a free flowing well and are transmitted separately to the surface. Liquid oil is transmitted through an elongated tubing which extends into a liquid column in the bottom of the well and is anchored in a liquid production tubing string to form an annular flow spa ...
