Adaptable to highly deviated or horizontal wells but must be set in straight section.
Permit use of minimum space for subsurface controls and associated production facilities.
ESPs are quiet, safe and require a smaller surface footprint compared to other lift systems, making them the best option in offshore and environmentally sensitive areas.
High volume capabilities. ESPs can accommodate the dynamic evolution of fluid properties and flow rates during the life of the well.
Provides for increased volumes and water cuts brought on by pressure maintenance and secondary recovery operations.
Allows placing wells on production even while drilling and working over wells in the immediate vicinity.
Applicable in a range of corrosive environments. The pumps can be manufactured from high-grade, corrosion-resistant materials for applications with high-GOR fluids, high temperatures and fluids containing corrosive acid gases.
Disadvantages Of Using An ESP Packer
Will tolerate only minimal percentages of solids in production. Although special pumps with hardened materials exist, ESP run times can be severely compromised in fluids with a high percentage of sand and solids.
Costly removal operations and lost production occur when correcting downhole failures.
With lower than 400 BBLD volumes, power efficiency drops sharply; ESPs are not particularly adaptable to rates below 150 BBLD.
Need relatively large (greater than 4½-in. outside diameter) casing size for the moderate- to high-production-rate equipment.
