METHOD AND APPARATUS FOR MONITORING THE CORROSIVE EFFECTS OF WELL FLUIDS

摘要

A method and an apparatus for monitoring corrosive effects of fluids downhole in an oil or gas well. A side pocket mandrel is installed in the well tubing string at a depth at which monitoring is desired. Coupons of a selected material are mounted in a carrier, which is placed in the side pocket of the mandrel. Ports and passages allow casing fluid or tubing fluid to communicate with various coupons. The carrier is then removed from the well and the coupons are inspected.
