Method for determining oil content of an underground formation using cuttings

摘要: Methods are disclosed for evaluating wet cutting from a well borehole to determine the hydrocarbon content of earth formations penetrated by borehole. The cuttings be measured mixed with polar solvent which has both hydrophilic and properties. solution is filtered then its emission (fluorescence) spectrum irradiating it ultraviolet radiation excitation at wavelengths most petroleum compounds fluoresce. sample determined comparing fluorescence known samples.
