Abstract: A comprehensive system for managing inventory, delivery and quality control of reusable downhole setting tools. Component parts are laser engraved with scannable unique identification codes for part trackability and traceability purposes. Tools can be function-tested before being shipped to a well site or other remote location to confirm operational integrity. Tested tools arriving at a well site or other remote location can be scanned and used in wellbore operations. Previously used tools can be packaged at the well site or other remote location, scanned for trackability/traceability purposes, and returned to a shop or other facility for rebuilding and/or refurbishment. The rebuilt and/or refurbished tools can be tested for operational integrity. The process can be repeated.

Abstract: A riserless marine package enables post-BOP utilization of both drill centers simultaneously using an offset riser system to significantly reduce turnaround time between drilling and casing operations and reduce associated costs. A sealing system of the riserless marine package, disposed above the subsea BOP, separates the drilling mud below the sealing system from the seawater above. Drillstrings and casing strings are run through the seawater and transit through the sealing device of the riserless marine package. The rig may assemble and operate a drillstring from the first drilling position and assemble and operate a casing or liner string in the second drilling position. Upon reaching total depth using the offset riser, the rig may trip the drillstring until the BHA clears the subsea BOP. Once the BHA clears the subsea BOP, the rig may then move to insert a casing string hanging from the second drilling position into the well.
