Abstract: A method, assembly and apparatus for equalizing pressure around a sealing device in a production or injection tree. The method includes coupling a circulating assembly to an oil field tree and forming an isolated region between a portion of the circulating assembly, a portion of the tree and a sealing device within the tree. Then, a circulating mechanism in the circulating assembly is adjusted to create a flow path between the interior of the circulating assembly and a location below the sealing device. When the pressure below the sealing device has substantially equalized with the pressure within the interior of the circulating assembly, the sealing device is removed through the circulating assembly. Further, remediation and production operations may be performed on wellbore tools or a subsurface formation below the tree.
