摘要

"Tool to determine the amount of a carbon isotope in a fluid and method for providing real time data indicative of the composition of a fluid hydrocarbon.Method and apparatus for providing real time data indicative of the composition and formation fluids during drilling.The method includes the steps of: (a) providing a reference fluid that has a known composition in a cell reference; (b) to capture a sample of training; (c) providing at least one beam.Laser; (E) to pass a beam through the reference fluid.To measure the beam of reference measurement before and after it passes through the reference fluid; (f) through a beam through the sample.To measure the beam before and after it passes through the sample, and calculating a first concentration of isotope from these measurements.The measurements may provide information concerning the carbon isotopic composition of individual compounds in the mixture of hydrocarbon gas, with the individual components including methane, ethane,Propane, isobutane and normal butane pentane, isopentane, and normal.
