Title: Method and apparatus for permanent measurement of wellbore formation pressure from an in-situ cemented location
Inventor: OIVIND GODAGER
IPC: E21B49/00
Filed: 2016-01-08
Abstract: The method for in-situ determination of a wellbore formation pressure through a layer of cement comprises: detecting an output pressure signal from a pressure sensor 6; detecting a first temperature signal from a first temperature sensor (51, figure 3); and calculating a temperature compensated output pressure signal based on the output pressure signal and the first temperature signal. Formation pressure acts on the pressure sensor via a porous string 12 that extends from the housing into the cement 22 and circumferentially about a wellbore casing 16 so that the porous string is in hydrostatic connectivity with formation fluid in the cement. The pressure sensor and first temperature sensor are disposed in a housing 5, which is in the cement outside the wellbore casing. Ideally the porous string has a higher porosity and hydrostatic connectivity than the cement and transfers fluid pressure to the pressure sensor via a pressure permeable filter port 3 on the housing and first and second oil-filled chambers 8,94 within the housing. The second oil-filled chamber ideally isolates the pressure sensor from the first oil-filled chamber.
