Automatic Surveillance System for Large Gas Fields With Multifrequency Measurements

摘要

This paper presents the results of an automatic surveillance system implemented by PEMEX for one of Mexico’s largest gas fields. Activo Integral Burgos (AIB) is a typical example of large gas field where production declined due to gas- loading backpressure and reduced permeability in the target formation. The fast decline of the gas wells during their first year of production drove a change from reactive into proactive management tactic to monitor the field and to select candidates for workovers. However, the large number of wells in AIB (approximately 2000 active wells) and the fact 95% of data is manually captured made the implementation of automatic surveillance particularly challenging.
