Abstract
A subsea tree for use with a well includes a master block that has a flow hub located at the top of the subsea tree, a flow bore in fluid communication with the well, a swab valve, and a master valve. A choke block is coupled to a side of the subsea tree and includes a choke in a flow passage of the choke block. The swab valve is selectively closed so that fluid flowing through the master block is directed through the choke in the choke block. A method for operating the subsea tree, includes directing flow of a first fluid into the flow bore of the subsea tree, through the choke of the choke block, and then into the flow bore of the subsea tree. The method includes reversing flow of a direction of a second fluid through the subsea tree.
