A system and method for improving the flow characteristics of gaseous slug-laden liquid hydrocarbon wells, particularly from horizontal, of similar boreholes. The invention provides a system and method which essentially homogenizes the liquid and the gas, utilizing a unique flow tube arrangement and a sequence of steps by first breaking up and separating the slugged gas from the liquid at a first location, and then gathering it into holding location - - i.e., an annulus section - - where it is re-introduced in controlled amounts into the liquid downstream of the first location. The gas is re-introduced into the liquid flow in such pre- determined and controlled quantities as to promote better pressure and flow characteristics of the hydrocarbon liquid product. Various alternative gas/liquid separation devices are incorporated into the system of the invention, which devices may be located either in a vertical wellbore or a horizontal wellbore, depending upon the particular well characteristics. Optionally, an electric submersible pump may be incorporated where needed to assist the mixed production flow toward surface. A compressor may optionally be provided in the gaseous holding location, where needed. An apparatus for homogenizing production fluid from an oil well having one or more horizontal bores is also disclosed. |
