...) to eliminate the strong pump interference and determines the speed through power spectrum peak detection. The principle of ANC is explained in detail. Computer simulation and laboratory tests have demonstrated the feasibility of a signal processor thus constructed. turbodrill computer simulation...

... using rescaled range (R/S) analysis in conjunction with power spectrum analysis, similar to the methodology of Hewett et al. The R/S analysis yields a fractal dimension that can be used to model the reservoir parameters. Both vertical and horizontal well log data can be characterized as fractional...
