A possible option to remove the bottleneck was to install an additional fourth skid (of the same duty) with the obvious constraints of space, weight and money. After an in depth feasibility study, Sulzer Pumps was able to upgrade the injection sets to provide 21 % additional flow utilizing the same drive system. The cost of the retrofit was one fifth of the cost of the new skid option and provided the predicted generation of additional oil revenue from approximately 250,000 USD per day.
