Abstract
A pressure measurement system for use with a subterranean well can include a chamber positioned in the well, the chamber having an upper portion and a lower portion as positioned in the well, and a device which, in response to gravity acting on the device, selects the upper portion of the chamber for communication with a line extending to a remote location. A method of measuring pressure in a well can include introducing a chamber into the well, then selecting a vertically upper portion of the chamber, and establishing communication between the upper portion of the chamber and a line extending to a remote location.
Claims16
A pressure measurement system for use with a subterranean well, the system comprising:
- a chamber positioned in the well, and the chamber having an upper portion and a lower portion as positioned in the well;
- and
- a device which, in response to gravity acting on the device, selects the upper portion of the chamber for communication with a line extending to a remote location, wherein communication between the line and the upper portion of the chamber is established via at least one of multiple vertically distributed communication ports in response to application of increased pressure to the line.
A method of measuring pressure in a well, the method comprising:
- introducing a chamber into the well;
- then selecting a vertically upper portion of the chamber;
- and
- applying increased pressure to a line extending to a remote location, thereby establishing communication between the selected upper portion of the chamber and the line, wherein less than all of multiple vertically distributed communication ports is opened in response to applying the increased pressure to the line.
