Well integrity measurement at St.Gallen field site by
temperature profiling within cased well bore sections
%X After shutting-in the well in 2013 it was planned to carry out an indirect well integrity check
on the accessible cased hole section “St.Gallen GT-1” well by simple means and a relatively
low budget through temperature profiling of the well within the easy accessible cased well
sections.
As a secondary goal, it was also aimed for determining – as a first ever indication throughout
the deeper subsurface of Northeastern Switzerland – the geothermal gradient for the
evaluated part of the well from the resulting data.
It was also an objective of these measures to provide a template for the plausibility check of
other well integrity tests with a pragmatic approach of a low-budget solution.
