| Abstract Scope |
Dissolvable magnesium in frac plugs must maintain integrity for the duration of the operation and dissolve fully thereafter. Lab generated dissolution estimates are often much shorter than what is measured in the field. This study compared standard water bath corrosion testing to autoclaves with and without a nitrogen purge at 95°C 1 wt% KCl. The water bath test dissolution rate fell within the range of the unpurged autoclave. There was a substantial decrease in the dissolution rate of the autoclave where the nitrogen was used for purging entrapped air. The reduced dissolution rate of the material in the purged autoclave appears to be representative of the deoxygenated downhole environment. The possible reasons of the dissolution rate reduction of magnesium in the deoxygenated environment will be explained and modelled in the paper. The study will demonstrate to industry that testing needs re-envisioned and faster dissolving materials used in field. |
