    摘要: A leak detection method tests a tubing collar of wellbore tubing. The leak detection method can include the steps of introducing tracer gas under pressure to a tubing collar, introducing water to the tubing collar, detecting the tracer gas from a sample obtained outside the tubing collar, controlling a water system, a gas system, and the gas analysis system, flowing the tracer gas under pressure to the tubing collar and then the water to the tubing collar sequentially and allow the sample to flow to a gas analyzer, initially pressurizing the tubing collar with the tracer gas to a first pressure, pressurized the tracer gas to a second pressure, obtaining the sample from outside the tubing collar, and analyzing the sample for the tracer gas by the gas analyzer, and providing an alert that indicates a leak is present in the tubing collar.

    摘要: The invention concerns a tracer material for tracing fluid flows from a hydrocarbon reservoir. The tracer material comprises a plurality of separate agglomerates. The agglomerates comprise clusters of particles. The particles carry a tracer composition. A retaining material at least partially overlies the tracer composition. The retaining material retards the release of the tracer material so that the tracer is released at a more constant rate over a longer period than in the absence of the retaining material.

    摘要: The present invention relates an Integral analysis method of inter-well tracer tests, which integrates and performs continuous feedback to each of the major stage (design, operation and interpretation) allowing quantitative interpretation of these tests. It is presented as a tool to investigate the behavior of injection fluids for recovery of hydrocarbons, as well as for the dynamic characterization of reservoirs. The main advantage of this invention is that it allows a greater certainty in the tracer response and a marked improvement in the sensitivity and quantitative analysis of the test results, since the curves fit both with mathematical models and numerical models. Another outstanding attraction of this invention is the reduction in the costs of testing such applications.
