Optimizing Well Integrity Surveillance and Diagnostic for Gas Lift Wells in Mature Fields - Case History in Egypt

摘要

GUPCO is one of the major companies in Egypt using Gas Lift for operating more than 500 wells across Gulf of the Suez (GoS). To ensure that wells operate as designed for their assigned life with all risks as low as reasonably practicable, GUPCO initiated an in house Well Integrity Management Policy (WIMP) with combination of well modeling to simulate the operating conditions. WIMP defines the operating standards for maintaining well integrity parameters, securing well potential availability and emphasizing on the problem prevention before happening. In addition, well modelling plays a vital role in such challenging mature fields that helps in decreasing Natural Flow Capability (NFC) physical test frequencies, especially for vast infrastructure.
