When an ESP fails, API RP 11S2 instructs how to pull the unit to preserve evidence. This includes:

API Recommended Practice 11S2 (API RP 11S2) provides the industry standard for performance testing of Electric Submersible Pumps (ESPs). It ensures that pumps delivered to the field meet consistent performance benchmarks for head, flow rate, and power consumption GlobalSpec Purpose and Scope api rp 11s2

The document outlines specific testing protocols that manufacturers must follow to verify performance. These include pressure testing, shaft seal integrity checks, and thermal expansion cycles. By standardizing these tests, the API ensures that hardware from different vendors meets a baseline level of durability. When an ESP fails, API RP 11S2 instructs

Requirements for the accuracy of pressure transducers, flow meters, and power analyzers. These include pressure testing, shaft seal integrity checks,

Modern ESPs often run on VSDs. API RP 11S2 acknowledges that VSDs introduce harmonics that can heat motor windings. It recommends:
