ABSTRACT:
A configurable wellhead system is used to efficiently accomplish well completion, re-completion or workover. The configurable wellhead system includes a permanent fracturing spool that is mounted to a casing head of the well and provides a high pressure seal around a top of a casing of the well. The permanent fracturing spool provides full-bore direct access to the casing without the use of a pressure isolation mandrel. A tubing head is mounted to a top of the permanent fracturing spool to complete the configurable wellhead system. A fracturing spool plug secured in a seal bore of the permanent fracturing spool permits equipment mounted above the permanent fracturing spool to be removed without killing the well or inserting a wireline casing plug.
