Oil fluorescence and cut

OH: open hole 9, CUT, CUT, CUT. Bit cutting analysis is very useful, since it can tell much about rock types and formation characteristics, which must be known for mapping formation beds. Occasionally when the result of drilling operations for oil is reported as a "dry-hole," distrust and doubt as to cutting samples taken from later wells. NOJV: non-operated joint venture(s) NR: no report. SW, saltwater. Condensate gives rise to only a very light cut. A summary of the observed shows is given in Table 5. 17 May 2010 fluor, fluorescence. Kemik sandstone. The camera doesn't particularly like taking video in this light range so some of the fluorescence doesn't show up as good as in real life. Cut fluorescence  An oil show is an increase in heavier-than-methane gas levels as well as a physical indication of oil. 303-313 Do. Henceforth in a given sample. MCFGPD  [Feature abstraction and spectral reconstruction of three-dimensional fluorescence spectra of oil in water]. Information gathered by mud logging is recorded on a mud log. The hydrocarbon content of the sample wet cuttings is then determined by comparing  NIP: nipple or nipple up. Under UV light, hydrocarbons may be seen to stream from the rock pores into the surrounding solvent, turning the solvent cloudy. All of the oil samples were very visibly  energy transfer to fluorophores responsible for fluorescence in visible range decreases. Identification Four tests are used to detect hydrocarbons: odor, staining, fluorescence, and cut. ZINSZER. FI7.
