Wireline logging is a term used in oil and gas sector to mean the bringing down a logging gadget joined to a wireline into an oil well to quantify the properties of the stone and the formation’s fluids

The estimations acquired are then translated and used to decide the profundities and areas where oil can be discovered. It is referred to as Wireline logging because the logging device is brought down through the oil well on the end of a wireline.

The history of Wireline logging is more than 80 years ago. Two Schlumberger brothers, Conrad and Marcel, were the first to run the principal wireline log in France at the Pechelbronn Oil Company.

Their exploratory logging endeavor was successful, and the siblings called their new method an electric survey. And in the mid-1930s in the USA the expression “well log” became a popular term.

Wireline logging devices are shaped like a cylinder. They go from a thin breadth of around one and a half inches up to around five inches. There are three fundamental types of wireline logging instruments.

Types of wireless logging instruments

The first measures the unconstrained potential. That is, the voltage difference between a terminal in the wireline logging apparatus and another cathode while the former is in the oil well and the latter at the entrance. This likewise has extra instruments to gauge the regular radiation originating from

The second sort of wireline logging apparatus has a wellspring of excitation and additionally a sensor. The detecting frameworks used as a part of this type can be attractive reverberation, inductive, electric, acoustic, or different strategies.

The third sort of hardware utilized is one that can play out some mechanical move. This kind of wireline logging apparatus can recover rock tests at different profundities to permit researchers to analyze the real development physically. It can also recover oil tests at decided profundities and convey them move down to the surface for analysis.

There are likewise contrasts in the sorts of electric log instruments utilized. They can be classified by whether they are used before the oil well is cased, and are along these lines open gap records, or after it has been cased, and in this way cased gap logs.

Electric logs are further characterized by the physical properties the device measures. It is a resistivity log when the particular resistance of the stone and liquids are measured. When a given volume of rock has its rate of pore volume measured, it is the porosity log instrument that is employed. Porosity logs use advances taking into account sound waves or atomic responses.

Benefits of wireless logging

The upsides of wireline logging are extensive. Wire logs give different arrangement parameters like Resistivity, Density, Conductivity, Gamma, and Porosity. These parameters help in characterizing the borehole development .They likewise help in identifying nearness of Hydrocarbons storage.

It permits the securing of important information at a quick rate and over a broad variety of profundities. This permits quick and precise choices to be made on boring, in light of the data got. Understanding the physical properties of an oil well is basic to legitimately overseeing it over its lifetime. Wireline logging makes that possible.
