Abstract
A method and apparatus for estimating the true temperature of connate fluid within a subterranean geological formation is provided herein. The method includes generating a flow of connate fluid, measuring the temperature of the flow over time until the measured temperature reaches a limiting value termed the stabilized temperature. Multiple events of temperature sampling events can be conducted at different flow rates of the connate fluid. The stabilized temperature values can then be ascendingly organized based on the value of their respective flow rates. The limiting value reached by the stabilized temperatures is taken to be substantially equal to the actual temperature of the connate fluid residing within the subterranean formation.
Claims12
A method of estimating subterranean formation connate fluid temperature comprising;
- (a) sampling connate fluid flow temperature for a period of time;
- (b) establishing a stabilized temperature value of the connate fluid flow of step (a);
- (c) repeating steps (a) and (b) and obtaining a stabilized temperature value for each corresponding connate fluid flow;
- and
- (d) estimating the temperature of connate fluid residing in the formation based on the relationship between the stabilized temperatures obtained for each flow of connate fluid and the flowrate for each connate fluid flow.
