Borehole logging is the practice of making a detailed record (a well log) of the geological formations penetrated by a borehole. The log may be based either on visual inspection of samples brought to the surface (geological logs) or on physical measurements made by instruments lowered into the hole (geophysical logs). Some types of geophysical well logs can be done during any phase of a well’s history: drilling, completing, producing, or abandoning. Well logging is performed in boreholes drilled for the oil and gas, groundwater, mineral and geothermal exploration, as well as part of environmental and geotechnical studies. Borehole logging solutions provides logging recovered cores that shall be examined by the naked eye and further examination of cores such as: litho logy, dip and strike, type of weathering, RQD, core recovery ,lugeon value etc.
