Name one application of borehole imaging.
Structural interpretation.
Which file format is normally used to deliver borehole image array data?
DLIS
Which direction we drill in?
parallel to Shmax
What are the two types of QC done?
Correlation Qc and Inclinometry Qc
What does a sinusoid on a borehole image usually represent?
A dipping geological feature (bed, fracture, etc.).
Best WL tool for washouts?
Quantageo
What do dark features and bright fractures indicate on a borehole image?
Dark features indicate conductive fractures.
* Bright features indicate resistive fractures.
Which plugin helps in thin-bed analysis
sand count
What is dynamic normalization?
converting static image into dynamic image
An engineer wants the highest-resolution image while drilling in WBM. Which LWD tool should be selected?
MicroScope-HD
Why is UBI considered mud-independent?
Because it uses acoustic waves rather than electrical current.
What is the purpose of button harmonization?
Processing step to detect the faulty buttons
What is the difference between FMI & FMI-HD
It’s electronics
If we have FMI , MDT , TCombo
What is the preferred sequence for logging?
Tcombo , FMI , MDT
If the well is drilled with oil-based mud and maximum coverage is required, which tool would you choose?
QuantaGeo.
Why does QuantaGeo achieve higher coverage than FMI?
Can acquire data during both downlogging and uplogging.
