This paper presents the production history of gravel packed wells which have experienced the deposition and removal of mainly strontium sulphate (SrSO4) scale. A scale prediction program is used to analyse the scale tendencies under both equilibrium and kinetic controlled conditions. The flow and scale characteristics of gravel packed and naturally completed wells are compared.
