... of positive benefit. The inverted shroud installation was expected to improve gas separation efficiency, leading to a reduction in the frequency of No Flow Events (NFEs), which were impacting production rates. The shrouded ESP performance on the first candidate well showed no NFEs with a significant increase...

... – typically production rates drop 50-80% of initial rates after the first year. The primary reasons for such reservoir behavior: transient inflow effect, no pressure maintained and fracture deterioration. Producing a wide and flexible range of production rates with high efficiency is a significant challenge...

... oil and gas operators to install one initial ESP at the completion of the well which lasts until production rates have declined to the conversion point of a lower rate form of artificial lift. This has significant cost savings implications both for capital and operational budgets, by avoiding...

... optimization to achieve an improvement in ESP performance. Unconventional horizontal wells have the complexity of depth, temperature, fluid composition, and rapidly declining production rates. Most artificial lift systems struggle and inadequately cope with inconsistent slug flows from a horizontal wellbore...
