Abstract
A method for in-situ determination of a wellbore formation pressure through a layer of cement, the method includes detecting an output pressure signal from a pressure sensor disposed in a housing in the cement outside a wellbore casing; detecting a first temperature signal from a first temperature sensor disposed in the housing; and calculating a temperature compensated output pressure signal based on the output pressure signal and the first temperature signal.
