Chapter 1 Flashcards
1
Q
What’s the full form of MWD?
A
Measurement while drilling
2
Q
LWD/MWD advantages include?
A
- Data is obtained in situations where wireline aqustion is difficult
- Acquiring data prior to the hole washing out
- Real time data is obtained for steering of a well
3
Q
GR is usually displayed with which of the following logs in the same track?
A
Calliper log
4
Q
In which porosity category given below would the empirically derived sonic porosity be much more realistic than given by Wyllie-time- average equation?
A
Porosity greater than 30%
5
Q
What is logging while drilling?
A
It is a technique that measure formations while being drilled. LWD tools provide deviation and logging options in high angle wells.

A
- GR
- Density
- Neutron
- Sonic
- Resistivity
7
Q
What does NMR stand for?
A
Nuclear magnetic resonance
8
Q
What is MWD?
A
Technology that provide information on directional surveys and other drilling related information in real time during drilling.
