Pemex selected six problematic wells to test the Pc3 Corrosion Control System, formally called the “Silver Hawg.”

All tests took place on small wells in several fields in Eastern Mexico with production below 200 BPD. Salient issues were a strong presence of carbonates in some wells and paraffin in other ones. All of these wells required maintenance interventions every thirty to forty-five days, consisting of physical cleaning, chemical treatment, and hot oil treatments. This maintenance always required shutting in the well to perform these activities. Because of carbonates or paraffin reducing the flow of the crude in the production tubing and the shut-in of the wells for maintenance, production was severely impacted.

After installation of the Pc3 System and reactivating the wells, Pemex’s records have indicated no down-hole maintenance for the paraffin or carbonate problems as well as a substantial increase in production. This increase is due to the well’s capability to produce to its potential month after month without build-up of paraffin, asphaltenes or carbonates and maintenance shutdowns.

The improvement of the wells is as follows:

*The tools installed in the Ogarrio 850 and Escoline 82 were installed without supervision and installed at the incorrect depth, this was corrected, and production improved.

The Pc3 System to control paraffin, carbonates, and asphaltenes have successfully proven to reduce the cost of maintenance, treatments and well downtime. Additionally, the Pc3 System has also demonstrated reductions of CO2 and H2S in wells for PDVSA.
