While classifying GTD, the process of segmentation aimed at
taking On-line decisions in drilling, a forecast of the beginning
or end of an interval, following and prediction of a working
period of a drilling bit, evaluation of wear of drilling tools,
prevention of emergency situations, breaking of equipment
and others [1].
The results of the proposed segmentation provide us a
geological situation through a well depth. The proposed
methods assume interactive interpretation of segmentation and
compression of GTD and a possibility of additional verifying
repetitions and variations. This is connected with division of
GTD into segments, their verification by the identified models
applying two, essentially different methods:
