Jun 1, 2023 · Introduction. Geological drilling is an indispensable process for deep geothermal development, geological prospecting, and mineral exploration. The complex geological environments with high temperature, high pressure, and high terrestrial stress contribute to undesirable drilling faults, such as drillstring failures, which can compromise human safety and increase the asset cost [1], [2]. Mar 1, 2022 · The difficulty of geological drilling lies in the invisible drilling process downhole. As the drilling depth increase, the drilling bit passes through various formations that span across multiple geological ages, and these formations may have complex stress, fluid volume increase and fluid movement mechanisms causing pore pressure to vary ...

Many software options are available to create and organize geologic information within a database. One example of database software is the DHDB (drill hole database) geologic database (Fig. 9) that was developed by Highland Geo-Computing. This user-friendly access based program provides a comprehensive drill-hole database that …The samples collected in course of drilling are used to prepare geological log or litholog or strata chart. In water wells, logs are likely to give (i) the thickness of the aquifer and (ii) depth to the porous and permeable zones. Drilling time log acts as a supplement to geological log which gives penetration rate and bit behaviour.
