Borehole Geophysical Techniques

Abstract

In arid lands water resources investigations, it is important to maximize the amount of data that is obtained from the drilling of test or exploratory wells. A key means of obtaining detailed data on the groundwater system being investigated is through borehole geophysical logging. Valuable hydrogeological data can be obtained from both newly drilled and existing wells. Borehole geophysical logging techniques allow for the continuous in situ measurement of the petrophysical properties and composition of the penetrated rock, sediment, and formation fluids. Borehole geophysical logging has long been a critical tool in the oil and gas industry because of the wealth of data that it can cost-effectively provide.
