COMPACT LUBRICATOR AND HEADER SYSTEM

A plunger lift lubricator assembly includes a lubricator and a header. The lubricator has a lubricator body defining a longitudinal inner bore, and an upper lubricator assembly comprising an anvil, spring cap, and a spring. The header is disposed immediately adjacent and parallel to the lubricator body, defines a longitudinal bore in fluid communication with the lubricator inner bore, and defines a header exit port with attachment means to external fluid handling equipment. The lubricator assembly has a horizontal dimension from the lubricator inner bore centre line to header exit port attachment means, which is the same as a horizontal dimension of a flow-tee of a wellhead. The lubricator can be installed in the wellhead by removing the flow-tee and replacing it with the lubricator assembly, without further modifying the wellhead to fit the lubricator assembly, and connecting the header exit port to the external fluid handling equipment.
