Method and apparatus for a tunable diode laser spectrometer for analysis of hydrocarbon samples
The present invention provides an down hole apparatus and method for ultrahigh resolution spectroscopy using a tunable diode laser (TDL) for analyzing a formation fluid sample downhole or at the surface to determine formation fluid parameters. In addition to absorption spectroscopy, the present invention can perform Raman spectroscopy on the fluid, by sweeping the wavelength of the TDL and detecting the Raman-scattered light using a narrow-band detector at a fixed wavelength. The spectrometer analyzes a pressurized well bore fluid sample that is collected downhole. The analysis is performed either downhole or at the surface onsite. Near infrared, mid-infrared and visible light analysis is also performed on the sample to provide an onsite surface or downhole analysis of sample properties and contamination level. The onsite and downhole analysis comprises determination of aromatics, olefins, saturates, gas oil ratio, API gravity and various other parameters which can be estimated by correlation, a trained neural network or a chemometric equation.

Downhole formation fluid contamination assessment
The present invention relates to a method of detecting synthetic mud filtrate in a downhole fluid including placing a downhole tool into a wellbore, introducing a downhole fluid sample into the downhole tool, analyzing the downhole fluid sample in the downhole tool, producing at least two filtrate markers from the analyzing of the downhole fluid sample and converting the at least two filtrate markers by vector rotation to a sufficiently orthogonal signal. The first pumped fluid sample giving initial plateau readings can be a proxy for 100% drilling fluid having an initial orthogonal signal and subsequent samples can be converted to orthogonal signals that are referenced to the first pumped fluid signal to give a calculation of percent contamination of the formation fluid.

Fluid sample analysis using class weights
ActiveUS7324694B2Improve determination accuracyReduce the amount requiredAcquiring/recognising microscopic objectsIndividual particle analysisAlgorithmParticle sorting
Most automatic particle classification methods produce errors. The invention provides a method for improving the accuracy of particle classification while shortening the amount of manual review time required from the operator. The method uses class weights, which are statistically-derived correction factors that accounts for frequency of classification errors. A first class weight and a second class weight are assigned to the first class and the second class, respectively. The number of particles in each of the first and the second classes is multiplied by the first class weight and the second class weight, respectively, to generate a corrected number of particles in each of the classes. If particles are reclassified, the class weights are recalculated in response to the reclassification. The method is usable with a complete classification where all the particles in a sample are classified, or a selective classification of a subset of the particles in the sample.
