| Abstract: | The Kalman filter is used in the Natural Gamma spectrum well logs. The concentrations of thorium, uranium and potassium are estimated from the five energy windows datas influenced by the statistical ebb-and-flows. As the stratigraphic change is unknown , the Gauss Markov process is used to destribe the change. The real measurement well logging datas are treated and the results show the effectivity of the method. |
