WebbWell logging, also known as borehole logging is therefore, the practice of making a detailed record (a well log) of the geologic formations penetrated by a well. The log may be based either on visual inspection of samples brought to the surface (geological logs e.g. cuttings logs, core-logging or petro-physical logging) or on physical WebbLOGitEASY's web-based soil logging and boring log software (LOGitEASY eForm) is usable both in the field and in the office for transferring field notes. Once the data is entered into the software, logs can be produced in a variety of templates, including LOGitEASY, gINT, LogPlot, and other.
