This document discusses using coiled tubing as a velocity string to address liquid loading in gas wells. It describes how liquid loading occurs and can limit gas production. Installing coiled tubing inside the existing tubing string increases flow velocity which helps remove liquids from the wellbore. The document outlines how to select the appropriate coiled tubing size and installation depth using nodal analysis simulations. It also provides details on how to design and install the coiled tubing velocity string to optimize gas well performance and production.
