What is the process of well logging?
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.
What is meant by well logging?
Well logging, also known as borehole logging is the practice of making a detailed record (a well log) of the geologic formations penetrated by a borehole.
What is well logging in geophysics?
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.
What are the types of well logs?
The standard well logs are the temperature log, the caliper log, and the resistivity log.
What is the importance of well logging?
Well logs are important to the petroleum industry because they provide numerous rock property measurements, like the reservoir conditions of pressure, temperature, and fluid content. The quality of well logs can vary significantly from one well to the other.
Why do we do well logging?
The main purpose of keeping a well log is to determine the suitability of the well for its intended use. Well logs are also used by researchers to explore the underground. There are different types of well logs depending on drilling needs.
What are the two different types of logging?
Logging is generally categorized into two categories: selective and clear-cutting. Selective logging is selective because loggers choose only wood that is highly valued, such as mahogany. Clear-cutting is not selective.
What are the different types of logging?
The Three Types of Logging Systems
- Clearcutting. Many large-scale logging companies use the clearcutting method to harvest timber.
- Shelterwood. Another common logging technique is the shelterwood system.
- Selective Cutting.
