Tubing Hanger Assembly with Adjustable Load Nut

A method of installing a tubing hanger assembly in a wellhead, the method comprising:

• providing the tubing hanger assembly with:
• a tubing hanger body;
• a downward facing load shoulder which is axially displaceable relative to the body;
• and
• first and second inclined surfaces configured to engage each other, one of the first and second inclined surfaces having a fixed axial position relative to the body and the other of the first and second inclined surfaces having a fixed axial position relative to the load shoulder;
• wherein the first and second inclined surfaces are configured such that rotation of one of the first and second inclined surfaces relative to the other of the first and second inclined surfaces results in axial displacement of the load shoulder relative to the body;
• lowering the tubing hanger assembly into the wellhead until the load shoulder is positioned on or axially adjacent an upward facing seat located in the wellhead;
• engaging a first lockdown feature on the tubing hanger assembly with a second lockdown feature in the wellhead to thereby secure the tubing hanger to the wellhead;
• and
• rotating the first and second inclined surfaces relative to each until the distance between the first lockdown feature and the load shoulder is the same as the distance between the second lockdown feature and the seat;
• wherein a force required to rotate the first and second inclined surfaces relative to each other is generated by a force member located in the tubing hanger assembly.
