Abstract
An apparatus for monitoring the pressure in a gas well at a downhole location is disclosed. The apparatus uses a capillary tube connecting a downhole monitoring assembly with a pressure gauge or gauges at the wellhead. The downhole monitoring assembly and capillary tube are located externally to the production tube so as not to block the production tube for cleaning or other uses. A passage from the interior of the production tube passes gas to the capillary tube in order to measure the pressure at the downhole end of the production tube.
Claims7
An apparatus for monitoring downhole pressure in a well, comprising:
- (a) a production tube comprising a downhole end, and further comprising an exterior and interior;
- (b) a capillary tube comprising a wellhead end and a downhole end, wherein said capillary tube is positioned to said exterior of said production tube;
- (c) a monitor tip adjacent to said exterior of said production tube, said monitor tip positioned near said downhole end of said production tube and in communication with said downhole end of said capillary tube;
- and
- (d) a pressure gauge in communication with said wellhead end of said capillary tube.
