Abstract
This paper reports part of an ongoing program to study the flow in a geothermal well. In this paper we look at the fluid processes that occur in the liner of the well and are particularly interested in the pressure losses that are associated with the slotted (perforated) liner. A data bank of well measurements has been analyzed to give a representative value of the liner roughness and a laboratory experiment was built to investigate the complex nature of the flow in the liner and annulus. Finally a computer simulation was developed which allowed an investigation of the effect of some of the variables on the fluid flow. These studies are reported together with some discussion and recommendations of values for liner roughness to use in wellbore simulations.
