Abstract
Many of the existing wells in underground storage formations are about to exceed their primary life time. It is therefore of great safety, technical and commercial interest whether existing wells can be further used and if so, how long in the future and under which operating conditions.
SEW is a user friendly software that supports the process of safety evaluation of wells. This software takes into account the pressure from rock formations acting on the casings, the corrosion potential of rock formations and process media involved as well as the influence of cavern roof subsidence. It allows simulation of the impact of casing failures on subsequent casings and it checks the collapse resistance, the internal pressure resistivity of tubulars and the axial load on tubing and anchor pipes.
Different loading case scenarios can be defined and investigated. The measurement data of casing inspections can be imported and used in the future as a new baseline for the calculation of casing degradation caused by corrosion.
