    摘要: Tracking fluid displacement along a wellbore using real time temperature measurements. A method of tracking fluid displacement along a wellbore includes the steps of: monitoring temperature in real time in the wellbore; and observing in real time a variation in temperature gradient between fluid compositions in the wellbore. Another method of tracking fluid displacement along a wellbore includes the steps of: monitoring temperature along the wellbore; and observing a variation in temperature gradient due to a chemical reaction in the wellbore. Another method includes the step of causing a variation in temperature gradient in the fluid while the fluid flows in the wellbore.

    摘要: A pressure communication assembly external to casing with various forms of connectivity to a pressure source. A well system includes a casing string positioned in the well, with a bore extending longitudinally through the casing string; a chamber attached to the casing string and positioned external to the casing string bore; and a device which provides fluid communication between an interior of the chamber and a pressure source external to the casing. A method of monitoring pressure in a well includes the steps of: installing a casing string in the well with a chamber positioned external to a through bore of the casing string, and the chamber being isolated from the well external to the casing string; and then actuating a device to thereby provide fluid communication between the chamber and the well external to the casing string.
