What is LWD measurement?

3 Logging while drilling. Logging while drilling (LWD or Measurement while drilling (MWD), the terms are used interchangeably) is a general term to describe systems and techniques for gathering down-hole data while drilling without the requirement to remove drill pipe from the well.

What does MWD stand for in drilling?

Measurement While Drilling
This process of guiding the wellbore is known as Measurement While Drilling (MWD) or Logging While Drilling (LWD). The Operators for these tasks, commonly referred to as MWDs or LWDs, are responsible for using the complex technology which provides a second-by-second feed on the progress of the bore.

Which drilling in lathe The drill is held in the?

Explanation: The tailstock of a lathe can be used for drilling, with the aid of a drill chuck attachment. The drill chuck has a morse taper shaft which can be push into the shaft of the tailstock, locking it in position.

What is wire line logging?

Wireline logging is the process of using electric instruments to continuously measure the properties of a formation, in order to make decisions about drilling and production operations.

Why is logging done during drilling?

Logging while drilling This allows drilling engineers and geologists to quickly obtain information such as porosity, resistivity, hole direction and weight-on-bit and they can use this information to make immediate decisions about the future of the well and the direction of drilling.

What is mud pulse telemetry?

The most common method for transmitting the data in deep boreholes is the so called mud pulse telemetry. The mud pulse telemetry uses the flowing drilling mud inside the drill string as a transmitting channel, whereby the information is transmitted either in baseband or in passband as coded pressure pulses or waves.

How long does it take to become a directional driller?

To become a directional driller, you need excellent mathematical and problem-solving skills, an understanding of mechanics, and patience. Attend a program at a directional drilling school; such programs can last up to eight weeks and teach the necessary skills and responsibilities of directional drilling.
