  • Method for drilling and casing a wellbore with a pump down cement float
    Patent number: 7757764
    Abstract: A cement float collar can be positioned downhole and used in a wellbore completion operation after drilling a wellbore with casing. The cement float collar is made for pumping downhole and into engagement with a groove formed in the casing, called the profile nipple. As such, no restriction is needed in the casing for accepting or latching the float collar and the portion of casing including the groove can be installed at the start of the drilling operation. In addition, the profile nipple can be used to engage other drilling tools and, therefore, can already be in placed when the final well depth (TD) is reached.
