Deepsea Yantai
N/A Planning LL with Wellesley
Carmen (35/10-10S) – Surface section
What was planned:
To run the 18 3/8″ WH and do the cement job with a stab-in stinger in two separate runs.
What was learned:
When using an Inner String to perform cement job, Inner string can be run below the Wellhead Housing Running Tools using a telescoping Joint to space out between the bottom of the Running Tool and the Stab in Receptacle inside the Float Joint. This eliminates the Risk of Stabbing the Stinger through the Top of the Wellhead Housing in open water and possibly damaging the 18.75 Wellhead Gasket profile. Saves on Rig Tripping Times.
