LSP
LSP
No electric parts in hole. Higher efficiency (surface motor). Long lifetime. Withstands
high temperatures. Attractive costs.
Depths limited to 200 m. Delicate handling (installation/removal). Definition of enclosing
tubing coating and bearing materials.
ESP
ESP
High submersion depths. Long lifetime. High flowrates in limited casing TD's (250 m3/hr in
9"5/8). Withstands high temperatures. Solution gas handling (in hole separator). Worldwide
service factilities.
Lower efficiency. Electric insulation
shortcomings. Higher costs.
HTP
HTP
Very long lifetime. No electric parts in hole.
Withstands very high temperatures.
Low efficiency (additional energy conversion item). Large diameters (OD's) required. Packer anchoring problems. High costs. Limited manufacturing/service facilities.
