Abstract
Apparatus and methods to analyze downhole fluids are described herein. A disclosed example method involves obtaining a sample of a downhole fluid, and depressurizing at least a portion of the sample. Additionally, a disclosed example method involves ionizing at least the portion of the sample, and analyzing the ionized portion of the sample to determine a parameter of the downhole fluid.
Claims30
A method of analyzing a downhole fluid, the method comprising:
- conveying a testing tool in a wellbore, the testing tool having an inlet, a depressurizer, an ionizer, and a fluid measurement unit;
- obtaining a sample of the downhole fluid via the inlet;
- depressurizing at least a portion of the sample via the depressurizer;
- measuring a depressurizing pressure of the at least portion of the sample;
- ionizing the at least portion of the sample via the ionizer;
- performing an analysis of the ionized portion of the sample;
- and
- determining a parameter of the downhole fluid from the measured depressurizing pressure and the analysis of the ionized portion of the sample.
