    Zaczyny cementowe odporne na zjawisko migracji gazu
    (2011) Kremieniewski, Marcin; Stryczek, Stanisław
    The article presents the research results of cement slurries resistant to the gas migration process during the bonding of the slurries in wellbore conditions (HTHP). The research was done on slurries with density range 1.48-1.84 g/cm3, the temperature range was 25-80 degrees of Celsius and the pressure range was 3-42 MPa depending on the conditions. The research was carried out on the specially constructed device. It enables the observation of the gas migration through the slurry in simulated wellbore conditions. The research results were than correlated with the slurry's setting time. Both new and previously used additives that prevent gas migration through the bonding slurry were added during the research.
