Apparatus and method for determining measures of the permeability of HC-bearing formations using fluorescence

摘要: Formation drilling cuttings are centrifuged and a sediment sample is extracted heated to burn off surface hydrocarbons. A non-fluorescing diluant added the sediment. The then subjected UV excitation. Depending upon permeability of sediment, speed at which emitted fluorescence brightens found vary. time brightness emission measured. time/brightness relationship proportional can be used calculate relative index for comparison other know parameters determine presence hydrocarbon likelihood being able produce from wellbore.
