Claim 16:
17. A method of installing a fluid flow regime modifier, comprising providing at least one fluid flow regime modifier within production tubing of a wellbore and at least partially within a fluid column of the production tubing, the production tubing including sections of tubing and a coupling between adjacent sections of tubing, the coupling including sockets at each end that receive ends of the adjacent sections of the production tubing defining a joint between the adjacent sections of the production tubing, the at least one fluid flow regime modifier including one or more fluid flow modifying features positioned in the coupling and between the ends of the adjacent sections and comprising an extension extending across the coupling or protrusions extending beyond a reduced internal diameter of the coupling between the adjacent sections of tubing and into the fluid column, the one or more fluid modifying features configured to reduce fluid fallback and impart a turbulent flow regime to at least a portion of the fluid column at the joint between the sections of the tubing and within the coupling.
