Abstract
Measuring the in situ temperature of a formation traversed by a borehole comprising lowering to a predetermined position in the borehole a tool that comprises a central conduit having an inlet an dbeing provided with a temperature sensor in contact with the fluid, means for analysing the fluid, and means for discharging fluid; allowing only formation fluid to pass through the central conduit; analysing the formation fluid; and measuring the temperature when the formation fluid is substantially uncontaminated.
Claims4
A method of measuring the in situ static temperature of a formation traversed by a borehole, which method comprises the steps of
- a) lowering to a predetermined position in the borehole a tool that comprises a central conduit having an inlet and being provided with a temperature sensor in contact with the fluid, means for analysing the fluid, and means for discharging fluid;
- b) making an exclusive fluid communication between the formation and the inlet of the central conduit;
- c) allowing formation fluid to pass through the central conduit;
- d) analysing the formation fluid;
- and
- e) measuring the temperature when the formation fluid is substantially uncontaminated.
