Solid propellants provide cost-effective stimulation in marginal wells

摘要

Bottom line. Many oil and gas wells can be stimulated effectively with a progressively burning, solid propellant that produces multiple fractures. The process is an economic alternative to hydraulic fracturing and other stimulation methods. Ashley Oil, Inc., treated five marginal Trenton limestone oil wells in Illinois, recovering about 10,000 bbo of incremental oil to date, with production still averaging 300% of pre-treatment rates a year or more later. Individual treatments typically paid out in two weeks or less. In another application, Royal Drilling and Producing experienced sustained injectivity improvements from injection well treatments.
