  • Analysis of gas flow yields recommendations for best cementing practices

    Ray T. Oskarsen, John W. Wright and Danny Walzel

    Although flow after cementing is common, usually it occurs from the surface casing at shallow depths. However, a well control incident that occurred on a shallow-water platform demonstrates that flow after cementing can take place for deeper casing strings. In this case, the 95⁄8-in. casing had been set and cemented following the cement program typically used in the area. The well began flowing while the crew was installing the slips, 4 hr and 45 min. after cement displacement. The shut-in casing pressure (SICP) rapidly built above the maximum allowable annular shut-in pressure, prompting an extensive mitigation operation until the well was controlled.
