Underbalanced Drilling (UBD) Flashcards
1
Q
What is Underbalanced Drilling (UBD)?
A
UBD is a drilling technique where the wellbore pressure is kept lower than the formation pressure to allow hydrocarbons to flow during drilling.
2
Q
Why is Underbalanced Drilling used?
A
UBD reduces formation damage, improves well productivity, and allows real-time reservoir evaluation while drilling.
3
Q
What UBD services does Blade provide?
A
Blade provides candidate reservoir screening, well design, engineering, and project execution services for UBD, focusing on efficiency and minimizing formation damage.
4
Q
What is candidate screening in UBD and MPD?
A
Candidate screening involves evaluating which reservoirs are suitable for UBD or MPD techniques, based on pressure conditions, formation type, and economic viability.
