During wellhead operations especially running casing hanger of conventional/stack wellhead, the containment (well control BOP) will be broken?
No, our casing hanger is designed based on the casing head size, and could be contained by CHH, so such operation of running casing hanger will not break the BOP.
Do you have running and retrieving tool for wear bushing and test plug?
Yep, we offer a test plug-wear bushing combination running and retrieving tool to running wear bushing, but for test plug, we do not have running and retrieving tool for itself and generally our client could use drill pipe (commonly NC 50 connection) to running the test plug.
How do you deal with the situation where the mandrel casing hanger does not sit well at proper position? Do you have any Plan B or emergency equipment in your supply scope?
Yes, as per client’s requirement, we will supply a slip casing hanger to address this issue. Slip casing hanger could be used to fix the casing and the casing need be cut as per the specified height to go into the bottom of THS. We have the secondary seal of BT, SF TYPE to seal casing.
In THS, when tubing hanger sits well, how do we judge the tie down screws work well to fix the tubing hanger well?
We could measure the length between the out surface of tubing head and the end of lock-down screw. The length should not exceed 60mm. It will explain that the lock-down screw goes into a proper position and will fix the tubing hanger well. And when lock-down screw is tightened at site, please kindly do it symmetrically to make the tubing hanger fixed in a balanced way.
How many seals are in your neck of tubing hanger? And do you have any running and retrieving tool for tubing hanger?
About the quantity of seals in the tubing hanger neck, it depends on the height of tubing hanger neck and client’s requirements. For the r/r tool of tubing hanger, we offer a (EUE/VAM TOP, or the others) connection on the top of tubing hanger, it could be run by a tubing with correspondence connection. There is no special tool.
