Deliverability Enhancement and Well Testing of Two Gas Storage Fields in Mt. Simon Formation - Case History

摘要

A pilot study was conducted in two aquifer gas storage fields completed in Mt. Simon formation located in North Central Illinois to select candidate wells for deliverability improvements. Eleven wells were selected to evaluate their responses to several different stimulation technique. HIgh pressure perforation washing, reperforating with high density charges, extreme overbalance surging (EOBS), selective injection packer acidizing (SIP), and coiled tubing acid injection were all used to reduce the near-wellbore pressure losses.
