Would you like to increase ESP runlife? I think the answer for most operators would be a resounding ‘yes’, especially in a low oil price environment. The goal with ESPs (or, for that matter, any other artificial lift method) is runlife extension. Driving extended runlife significantly reduces artificial lift cost and Lease Operating Expense (LOE). This article will provide an overview of what we need to do differently to increase the runlife and reliability of ESPs. On unconventional wells, it’s typical to see dismal runlife as shown in Figure 1. Would you be happy with this kind of runlife statistics – an average runlife of 142 days.
