摘要

It could be argued today that oil companies would be betterrndescribed as water companies. Total worldwide oil productionrnaverages some 75 million barrels per day and, while estimatesrnvary, this is associated with the production of 300 –rn400 million barrels of water per day. These values ofrnapproximately 5 – 6 barrels of water for every barrel of oil arernquite conservative. In the United States, where many fieldsrnare depleted, the ratio of water-to-oil production is closer torn9 to 1. In some areas around the world, fields remain onrnproduction when the ratio is as high as 50 to 1.rnWater production is a harbinger of problems in an oil well.rnIt can cause scaling problems in susceptible wells, inducernfines migration or sandface failure, increase corrosion ofrntubulars, and kill wells by hydrostatic loading, amongst otherrnthings. Thus, while water production is an inevitablernconsequence of oil production, it is usually desirable to deferrnits onset, or its rise, for as long as possible.rnNumerous strategies, both mechanical and chemical, havernbeen employed over the years in attempts to achieve this.rnSimple shut-off techniques, using cement, mechanical plugsrnand cross-linked gels have been widely used. Exotic concepts,rnlike relative permeability modification (RPM), have also beenrnapplied with varying degrees of success.rnThis paper is a continuation of a previous one, whichrnreviewed the traditional techniques and proposed some newrnmethodologies and technologies that can be used in the designrnof RPM treatments, in particular.1 Additional new insightsrnoffered in this paper include the extension of matrix RPMrntreatments to more extreme well conditions, such as heavyrn(viscous) oil and low pH environments. It also introduces thernconcept and reviews several case histories of the usage ofrnRPM systems to perform hydraulic fracturing treatments tornsimultaneously stimulate oil and control water. Thisrnconformance-fracture technique could significantly impact therndevelopment strategies of many fields worldwide.
