Abstract:
1. A method for detecting crude oil or gas in a drilling sample, comprising: extracting a drilling sample from a first drilling hole in a ground; introducing the˜drilling sample into a sample solution containing nano particles; illuminating the sample solution comprising the drilling sample and the nano particles by a laser beam in the vicinity of the first drilling hole; collecting light scattered by the drilling sample and the nano particles in the sample solution; obtaining a Raman spectrum from the light scattered by the drilling sample and the nano particles in the sample solution; identifying, in the Raman spectrum, a spectral signature associated with a substance around a predetermined Raman shift; determining crude oil or gas content in the drilling sample based on the spectral signature of the substance in the Raman spectrum; and in response to the crude oil or gas content determined in the drilling, adjusting drilling depths or locations of one or more drilling holes in real time.
