Latest Patents
One of Derrick's latest patents is a rotating control device designed for drilling systems. This innovative device employs a rotating control mechanism that forms a dynamic seal between the housing and the exterior of the string, effectively isolating the wellbore annulus under both positive and negative differential pressure. The design includes a sleeve that is rotatively disposed within the housing and is supported by a thrust bearing assembly. Additionally, the device features seal retainers that are coupled to the sleeve, each containing a resilient element that adjusts its sealing position based on the differential pressure across it.
Another notable patent addresses the mitigation of swab and surge piston effects in wellbores. This method involves selectively managing fluid communication between sections of a wellbore on either side of a well tool string. By detecting threshold movements of the well tool string, the system can increase or decrease fluid communication, thereby stabilizing pressure variations that may occur during drilling operations.
