Integration of ANFIS, NN and GA to determine core porosity and permeability from conventional well log data

New estimation methodologies for well logging problems via a combination of fuzzy Kalman filter and different smoothers

“…There are many methods in the literature for improvement of the estimations of the elements , and , such as Guy Ruckebusch, 1982 and1983 [2, 14] and Murray, 1987 [4]. Most of the recent activities in the field of well logging were similar to the article [15].A smoother based on the fuzzy adaptive Kalman filter was introduced in [16] for estimation of well-log data problems. Although the suggested filter can estimate, the well-log data, but there is still a large amount of noise on in the data.…”

The application of fuzzy adaptive Kalman filtering and smoother Kalman for well logging tool

“…Although, in [2] to applied adaptive Kalman filter, the gamma value is required, whereas the technique is presented in a paper this requirement resolved. In [8] integration of ANFIS, NN and GA for modeling perturbation of well log data to determined core porosity and permeability from conventional well log data is used. Most of the recent activities in field of well logging are similar to [8].…”
