Popis: Summary Gas migration has been a significant problem in cementing wells drilled in the Praire du Chien formation. Several types of gas-migration cementing systems have been used successfully during the past several years, but only recently has an analytical method been developed to help quantify the nature of gas-migration potential on an individual well basis. Once the probable limits of the gas flow have been established, it is possible to match an appropriate gas-migration-control cementing system for a specific set of well parameters. An important aspect of this process is computer analysis that establishes the probability of gas migration for a given set of well conditions and then selects an effective strategy for designing the cementing program for that particular set of conditions. This paper presents case histories illustrating applications of gas-migration-control cement systems with particular emphasis on the job design process.
