Nalco Champion’s research centre specifically formulated a new product suite for paraffin inhibition that would stand up to colder climates while achieving a high level of performance. The chemistries are not only stable to -40°F – they also show improved performance as compared to the current paraffin inhibitor offering. Nalco Champion recommended PARA13115A for a field trial, starting the trial at 750 ppm (the same injection rate as the incumbent chemistry), then further optimizing the rate down to 500 ppm. The well selected for the trial was a low GOR rod pump well located near Fort Lupton, CO and the chemistry was to be applied in the same fashion as the incumbent, via continuous injection down the backside of the well. The success of the treatments was to be measured by monitoring the differential pressures across the tubing string and the flowline leading to the separator.
