Abstract
A wellhead system includes a wellhead including a position sensor disposed in an inner surface of the wellhead, and a wellhead component to be installed in the wellhead, the wellhead component including a position indicator disposed in an outer surface of the wellhead component, wherein the position sensor is configured to transmit a position signal in response to the wellhead component entering into a predetermined aligned position in the wellhead.
Claims18
A wellhead system, comprising:
- a wellhead comprising a position sensor disposed in an inner surface of the wellhead;
- and
- a wellhead component to be installed in the wellhead, the wellhead component comprising a position indicator disposed in an outer surface of the wellhead component and configured to contact a landing shoulder of the wellhead as the wellhead component enters into a predetermined aligned position in the wellhead;
- wherein the position sensor is configured to transmit a position signal in response to the position indicator contacting the landing shoulder of the wellhead and the wellhead component entering into a predetermined aligned position in the wellhead.
A wellhead system comprising:
- a wellhead comprising a bore;
- and
- a wellbore monitoring assembly coupled to the wellhead, wherein the wellbore monitoring assembly comprises:
- a sensor package disposed in a sensor housing, wherein the sensor package comprises a temperature sensor and a pressure sensor;
- a window disposed in a receptacle of the wellhead;
- a sealing interface disposed between the window and the receptacle of the wellhead, wherein the sealing interface comprises a primary seal between the bore of the wellhead and the surrounding environment and
- a gasket disposed between the sensor housing and an outer surface of the wellhead, wherein the gasket comprises a secondary seal between the bore of the wellhead and the surrounding environment.
A method of landing a wellhead component in a wellhead, comprising:
- disposing the wellhead component in a bore of the wellhead;
- disposing the wellhead component in a predetermined aligned position in the bore of the wellhead, whereby a position indicator disposed in an outer surface of the wellhead component contacts a landing shoulder of the wellhead as the wellhead component enters into the predetermined aligned position;
- and
- transmitting a position signal from the position sensor in response to contacting the landing shoulder of the wellhead with the position indicator and disposing the wellhead component in the predetermined aligned positioned.
