What is open hole logging?

What is open hole logging?

Open-hole logging refers to logging operations that are performed on a well before the wellbore has been cased and cemented. In other words, the logging is done through the bare rock sides of the formation.

What is PEX log?

Platform Express integrated wireline logging tool is half the length of conventional triple-combo logging but twice as fast. The combination of higher logging speeds, reduced set-up and calibration time, and faster turnaround for wellsite processing boosts logging efficiency and requires significantly less rig time.

What is down hole logging?

Downhole logs are used to determine the physical, chemical, and structural properties of formations penetrated by drilling and to complement discrete core measurements. Where core recovery is incomplete, logging data may serve as a proxy for lab data for sedimentological and physical properties.

What are logging tools?

The downhole hardware needed to make a log. The term is often shortened to simply “tool.” Measurements-while-drilling (MWD) logging tools, in some cases known as logging while drilling (LWD) tools, are drill collars into which the necessary sensors and electronics have been built.

What are the three 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.

What is well logging techniques?

“Well logging, also known as wireline logging, is a method of data collection in the borehole environment which enables the determination of subsurface physical properties and reservoir parameters.

How is well logging done?

Wireline logging is performed by lowering a ‘logging tool’ – or a string of one or more instruments – on the end of a wireline into an oil well (or borehole) and recording petrophysical properties using a variety of sensors.
