Abstract: A system and method of measuring pressure in highly deviated or horizontal wellbores. In a described example, a pressure measurement system includes an apparatus which has a tube wrapped helically about a tubular mandrel. The tube is connected to a line extending to a remote location. A predetermined fluid is displaced through the line and the tube, so that fluid pressure in a well at the apparatus may be measured at the remote location.

Abstract: A system is provided for measuring both the temperature and pressure of fluid in a borehole utilizing a single small diameter tube extending from the surface to the desired downhole test location in a borehole. Downhole fluid pressure is transmitted through the small diameter tube, while a sheathed thermocouple or fibre optic line extending along the flow path of the tube is used for transmitting downhole fluid temperature information to the surface. A continuous surface read-out of both pressure and temperature is thus possible, and the temperature read-out may be used to both monitor downhole fluid temperature and increase the accuracy of the fluid pressure measurement system.
