Well logging, also known as borehole logging is the practice of making a detailed record of the geologic formations penetrated by a borehole. The log may be based either on visual inspection of samples brought to the surface or on physical measurements made by instruments lowered into the hole. Some types of geophysical well logs can be done during any phase of a well's . Lithologging of drill core of boreholes is an important stage in mineral exploration and it is done in reconnoitery, exploratory and evaluation stages of drilling to characterise the lithology. What is lithologing? Lithologging is systematic, depth wise enumeration of details of Core/Sludge samples or rock exposure in cross sections. Objective of lithologging: The basic objective [ ].
GAMMA LOG Records the natural-gamma radiation emitted from rocks penetrated by the borehole. The gamma log often is used to define lithology and correlate geologic units between boreholes.

Unique borehole logging tool provides immediate and fool-proof uranium analysis within the borehole by using neutron activation to measure U PFN used in discovering Australia's most recent uranium mine – Beverley – and the Four Mile mine development in South Australia and is in daily use at many uranium mines in the USA. OPEN HOLE WIRELINE LOGGING Self Learning Module This document is part of a self learning programme designed for new petroleum engineers with limited experience of logging operations. Experienced engineers not directly involved with logging operations but who would like to learn more about the subject may also find the module useful.

Both well logging and borehole geophysics are assuming greater importance in mineral exploration and development as targets become deeper, as drilling costs increase, and as solution mining becomes necessary. Borehole logging is a basic tool in the exploration for and delineation of uranium deposits.
The radioactivity associated with the uranium can be used for the quantitative evaluation of the uranium content of rocks intercepted by the borehole.
Selected Papers on Applications of Nuclear Techniques in Minerals Exploration, Mining and Process ControlPages Borehole Logging for Uranium by Measurement of Natural γ-RadiationCited by: It is the first book to cover modern borehole imaging, measurement of fluid flow, in-situ mineralogical logging, logging while drilling, full-wave acoustic logging and electromagnetic wave resistivity, all of which have gained in importance since the first edition and none of which are explored in detail in any other by: Gamma logging for uranium exploration and mining is an established technique for producing a rapid and cost effective depth based profile in a borehole of uranium ore grade.
The most common measurement systems involve a scintillation system where gamma photons are converted to light energy enabling digital count rate conversion.
A well location sketch. Technical Information During the drilling of a borehole, specific technical information about the unconsolidated material and rock encountered should be recorded on the drilling log sheet. The following minimum technical information should be recorded: Depth that sample was collected or encountered;File Size: 2MB.

A logging manual that is a combination of a description of borehole geophysical and petroleum logging devices and methods of using them is presented.
Geophysical and petrophysical logging are usually used in the context of making a measurement and a record of a borehole in the earth.
present technical status of nuclear borehole logging techniques, to find out the well established applications and the development trends. This report contains a summary report giving a comprehensive overview of the techniques and applications, and a collection of research papers describing work done in individual institutes.
Summary. Gamma-ray logging has evolved from a qualitative estimation of the variation of natural radioactivity with depth in a borehole, using a Geiger-Müller detector, to a sophisticated quantitative logging technique which yields information on the identification and amount of the radioelements present, as well as data on the likely geologic history of mobilisation of these Cited by: 6.
The resources in a large syngenetic deposit of low-grade uranium (U) ore with thorium at Kvanefjeld, South Greenland, were evaluated by spectrometric gamma-ray logging of 23 boreholes, 46 mm in diameter and m by: 4.
Geohysical well logging. Geophysical well logging (borehole logging,) is a set of borehole investigation methods that are based on special logging tools. First developed in the beginning of the 20th century, well logging comprises today several tens of methods that involve measurements of natural or induced physical fields in the borehole.
Types of Logging Well Logging. Mud logging, also known as hydrocarbon well logging, is the creation of a detailed record (well log) of a borehole by examining the bits of rock or sediment brought to the surface by the circulating drilling medium (most commonly mud).
Mud logging is usually performed by a third-party mud logging Size: KB. Well logging analysis: methods and interpretation 1.

Basic Well Log Analysis for Geologists (AAPG Methods in Exploration 3) George B. Asquith, Charles R. Gibson Basic Well Log Analysis is a general introduction to common openhole logging measurements, both wire line and MWD/LWD, and the interpretation of those measurements to determine the traditional analytical goals of porosity, fluid.
Borehole thermal methods have been applied in geothermal exploration, but have seldom been used in mineral exploration. However, this method has potential usefulness in exploration and in geoenvironmental investigations (Ovnatanov and Tamrazyan, ; Brown and others, ; Zielinski and others, ; Houseman and others, ).Borehole investigation.
