Latest Patents
Schafer's latest patents include the "Reclosable Multi Zone Isolation Tool and Method for Use Thereof." This apparatus is designed to isolate a first zone from a second zone in a subterranean wellbore. The invention features an outer tubular and an inner tubular that creates an annular flow path, allowing for fluid communication with the first zone. The inner tubular also defines a central flow path that connects to the second zone. A sleeve with at least one seal is positioned in the annular flow path and can move axially between a closed position, where the seal engages the inner tubular, and an open position, where the seal engages the outer tubular. A mandrel within the inner tubular is coupled to the sleeve and can shift the sleeve between these positions in response to pressure changes within the central flow path.
