Well logging is an evaluation method in which a logging crew lowers a special tool, a sonde, into the well and then pulls it back up. As the sonde passes the formations on its way up the wellbore, it senses and measures electrical, radioactive, and acoustic (sound) properties of the rocks Well logging is actually used not just for water wells, but also for oil wells. Researchers also use well logging as a means to perform geothermal, geotechnical, and environmental studies. Well.. What is well Logging Well log is a continuous record of measurement made in bore hole respond tovariation in some physical properties of rocks through which the bore hole is drilled. Traditionally Logs are display on girded papers shown in figure. Now a days the log may be taken as films, images, and in digital format Normally data is recorded as the logging instrument is pulled up the borehole from the bottom. This process is referred to as logging the well. Since the 1930s, many types of well logs were developed: Caliper - hole diameter measurement. It was performed with a probe fitted with pads that adhere to the walls of the well and whose position is continuously recorded to the bottom of the well
. The study involves the following well logging parameters: gamma ray (GR), deep resistivity (REID), self-potential (SP), formation density (DEN), and sonic log (DT). It can be extended, with appropriate modifications of the algorithm, in. Presented by Dr. Fred Schroeder, Retired from Exxon/ExxonMobilPresented on June 20, 201 During the early days of commercial well logging, logs were primarily used qualitatively for making formation correlations; within a given field or local geological province, certain formations have distinctive characteristics that appear remarkably similar from one well to the next, providing geologists with a basis for locating the depths of various strata in the subsurface Learn to select and apply the appropriate well logging tools for a particular set of well conditions and reservoir study parameters.

Well Logging Definition. Well logging, field technique used in mineral exploration to analyze the geologic formations penetrated by a drill hole. If the hole has been drilled by using coring techniques, the core provides a visual record of the formations and rock types encountered. The description (log) of the core provides the basic data used. Well logging is the practice of recording and analyzing various kinds of data about the rock formations around a borehole during or after drilling. Also called borehole logging, this activity aims.
Determination of saturation. Water saturation is the fraction of the pore volume of the reservoir rock that is filled with water. It is generally assumed, unless otherwise known, that the pore volume not filled with water is filled with hydrocarbons. Determining water and hydrocarbon saturation is one of the basic objectives of well logging well log correlation, together with examples of lithologic interpretation and expressions of stratigraphic and structural features which can sometimes be recognized on well logs. For the past 35 years, geologists and engineers have correlated electric and radioactivity logs.. Experience soon demonstrated that the induction log had many advantages over the conventional ES log when used for logging wells drilled with water-base muds.
