Latest Patents
One of David's latest patents is the "Re-closable coil activated frack sleeve." This invention features a bottom hole assembly designed for performing borehole treatments. It includes multiple ported valve housings with an assembly of shifting sleeves. The first sleeve is shifted uphole to open the port in the housing and locks in the open position. A second sleeve is then shifted in the same direction to close the ports, featuring profiles that allow it to be moved back down to reopen the housing ports after closing them.
Another significant patent is the "Positive locating feature of OptiPort." This system and method for treating a portion of a wellbore includes a bottom hole assembly connected to a work string. The assembly features a packing element that can move between unset and set positions, along with a locator device that can be retracted or expanded. The locator device engages a profile in a ported tubular within the wellbore, preventing further movement of the assembly and indicating its location. This allows for effective treatment of the wellbore through a port in the ported tubular.
