摘要： A technique usable with a subterranean well includes deploying a first optical sensor downhole in the subterranean well. The technique includes observing an intensity of backscattered light from the first optical sensor to measure a distribution of a characteristic along a portion of the well. The technique includes deploying a second sensor downhole to measure the characteristic at discreet points within the portion. The second sensor is separate from this first sensor and includes at least one interferometric sensor.

摘要： Methods and apparatuses for investigating formations surrounding a borehole involve acquiring a fluorescent signal over a portion of the borehole and analyzing the signal to detect the presence of crude oil. Analyzing the signal to detect the presence of crude oil may involve distinguishing mineral fluorescence from oil fluorescence. The signal may be analyzed further to distinguish characteristics of the crude oil, such as its grade (light, medium or heavy), and to indicate a physical property correlated with the fluorescence, such as the presence of laminations or formation permeability. In some embodiments, fluorescence signals from illuminating the portion of the borehole with at least two different wavelengths of light are analyzed.

摘要： A method and apparatus is provided for determining OBM filtrate fraction in a downhole fluid sample. One embodiment of the method is used when there is significant difference between the coloration of formation fluid and the coloration of OBM filtrate. Another is used when there is little or no difference between the coloration of formation fluid and the coloration of OBM filtrate. Another determines GOR of formation fluid corrected for OBM filtrate contamination. Another determines OD of formation fluid corrected for OBM filtrate contamination. Another determines conditions that would render optical density measurements invalid and sample capture premature. Another predicts the reduction of filtrate fraction for a specific extended pumping time. Another initiates sample capture when computed contamination fraction exhibits stable asymptotic convergence.
