Abstract
A well configuration and method of increasing production from a hydrocarbon well having pre-existing production tube. A composite velocity string having an outer diameter smaller than the inner diameter of the production tube is installed in the production tube so that an annular gap is formed between the outer surface of the velocity string and the inner surface of the production tube. Production from the well is increased because the coefficient of fluid flow friction through the composite velocity string, and the amount of heat loss through the composite velocity string, are reduced compared to a steel velocity string. Installation efficiency is also increased because the composite velocity string is much lighter than a steel velocity string.
