Bernt Ståle HollundStavanger, 14 June 2010   II Sammendrag En form for kunstig løft som har vært benyttet i mange tiår er “Electrical Submerged Pumps”(ESP). ESP ble først benyttet i 1926, siden har teknologien utviklet seg langsomt og dagensdesign har mange likheter med det srcinale systemet. ESP blir benyttet i stadige tøfferereservoar forhold, med hensyn på temperatur, viskositet, GOR etc. Dette er en stor utfordringfor levetiden til ESP. Derfor er det nødvendig å forbedre eksisterende teknologi for å kunnebenytte pumpene på en kostnadseffektiv måte.Denne rapporten inneholder anbefalinger for ESP design og tilstandsovervåking for Peregrinofeltet. Disse anbefalingene er basert på en oversikt av ESP feil-orsaker utført i en database vednavn ESP-RIFTS. Den anbefalte design løsningen består av en ESP med; faste impellere,tandem tetningsseksjon, oppgraderte tekniske spesifikasjoner med vekt på materialer, ogbenyttelse av avstandsprober for vibrasjonsovervåking. I tillegg er en livssykluskostnadsanalyse utført som identifiserte utskiftnings operasjoner av ESP som den mest kritiskekostnadsdriveren for Peregrino.   III Abstract One form for artificial lift that has been used for decades is Electric Submersible Pumps(ESP). Since the birth of ESP in 1926 has the technology evolved slowly and ESP used todayhas a lot of similarities with the srcinal system. Operators are utilizing ESP in more andmore challenging reservoirs with respect to temperature, viscosity, GOR, etc. This is a majorchallenge for ESP run life, so it is necessary to improve the existing technology to gain profitfrom producing oil with ESP.This report includes recommendations for ESP design and surveillance for the Peregrino field.These proposals are based on a survey of ESP failures conducted in the database ESP-RIFTS.The proposed ESP design includes; use of compression pumps with tandem seals, upgradedtechnical specifications with concern to materials, and utilization of proximity probes forvibration measurement. In addition is a LCC analysis performed, that identified work-overcosts as the most critical cost drivers for Peregrino.
