Introduction Geologic logging involves keeping detailed records during the drilling of boreholes, the installation of monitoring wells, and the excavation of test pits, and entering the geologic de­ scriptions of the soil and rock samples recovered on a standardized form.Geologists describe rock extracted by drills to understand the geology below the surface. Logging of sedimentary or volcanic rocks above ground is also used to study past environmental changes or accurately record sampling locations. Some types of logging include: Rock core logging (or rock chip logging) for mining and exploration companies.The time domain drilling data is sampled even when the well is not drilling and these data are useless or even harmful for building the ROP model. Further, since drilling data in the depth domain is more convenient in drilling engineering, a re-sampling method is adopted to convert the data from time domain to depth domain.The examination of the drilling mechanism revealed that the drilling energy is dissipated in different drilling stages, as shown in Fig. 1 and Eq. (1), and the following effects were produced by the energy: (1) rock breakage, which is the desired result (Poletto, 2005); (2) other effects due to heat.In addition, the development of radial cracks involves …Exploration drilling. Prospecting and exploration drilling is the first phase in the life cycle of a mine, followed by development, extraction and finally closure and reclamation. These activities involve searching for mineral deposits using a variety of geological methods which often occur simultaneously and can take 2–8 years to complete.Geological principles state that if a fragment of rock is included, that is entirely surrounded by rock, it must be older than the surrounding rock. This is because it had to be present for the rock to form around it.

Synthesis of geological aero geophysical & remotely sensed information data, creation of data base for further study.
