METHODS FOR COMPOSITIONAL ANALYSIS OF DOWNHOLE FLUIDS USING DATA FROM NMR AND OTHER TOOLS

摘要

Methods and apparatuses are provided for analyzing a composition of a hydrocarboncontaining fluid. The methods include using a nuclear magnetic resonance (NMR) tool to conduct an NMR measurement on the hydrocarbon-containing fluid to obtain NMR data. A non-NMR tool, such as an optical tool, is used to conduct additional measurements on the hydrocarbon-containing fluid and to obtain non-NMR data on the fluid. An indication of the composition of the fluid can be determined by using the NMR data and the non-NMR data in an inversion process.
