A study of test data for a number of Alberta gas wells has revealed that flow during such tests is seldom in the ″fully developed″ turbulence region. Because computer programs used to calculate pressure profiles usually assume ″fully developed″ turbulent flow, they tend to underestimate the friction factor, and as a result the pressure drop due to friction, in such wells. In order to avoid such bias, a subroutine, which generates the Moody friction factor chart, is presented and recommended for use in computer calculation.
