Abstract
A gas seal testing method for ensuring proper sealing function of wellhead sealing component such as a tubing hanger, a casing hanger, or a wellhead test plug may comprise detecting gas pressure in a gas seal testing port in the wellhead sealing component, the wellhead sealing component being inserted inside a wellhead and including at least one outer seal member extending around a side surface of the wellhead sealing component and purposed for forming a seal between the wellhead sealing component and the wellhead.
Claims13
A gas seal testing method for ensuring proper sealing function of a wellhead sealing component, the method comprising:
- providing a gas seal testing port in the wellhead sealing component;
- detecting gas pressure in the gas seal testing port provided in the wellhead sealing component, the wellhead sealing component being inserted inside a wellhead and including at least one outer seal member extending around a side surface of the wellhead sealing component and purposed for forming a seal between the wellhead sealing component and the wellhead,
- wherein the gas seal testing port extends between a top surface of the wellhead sealing component and the side surface of the wellhead sealing component to provide a top opening and a side opening in the wellhead sealing component with a continuous passage therebetween,
- wherein the wellhead sealing component is comprises a tubing hanger, a casing hanger, or a wellhead test plug,
- wherein the wellhead sealing component is separate from and removably insertable into the wellhead, and
- wherein detecting gas pressure comprising introducing gas through the top opening, restricting gas flow through the side opening, and measuring resulting gas pressure via a pressure gauge inserted in the top opening to determine proper or improper sealing function.
A wellhead sealing component, comprising:
- a gas seal testing port in a main body of the wellhead sealing component,
- at least one outer seal member extending around a side surface of the main body and purposed for forming a seal between the wellhead sealing component and a wellhead into which the wellhead sealing component is inserted,
- wherein the gas seal testing port extends between a top surface of the main body and the side surface of the main body to provide a top opening and a side opening in the main body with a continuous passage therebetween,
- wherein the wellhead sealing component comprises a tubing hanger, a casing hanger, or a wellhead test plug,
- wherein the wellhead sealing component is separate from and removably insertable into the wellhead,
- wherein the gas seal testing port enables the wellhead sealing component to be tested for ensuring proper sealing function therein by introducing gas through the top opening, restricting gas flow through the side opening, and measuring resulting gas pressure via a pressure gauge inserted in the top opening to determine proper or improper sealing function.
