Question

Four different multilateral well patterns (Forked, Branched, Dual opening and Splayed) are shown in the figure. Which ONE of the following options correctly identifies the multilateral well patterns?

• A. I – Forked; II – Branched; III – Dual Opening; IV – Splayed
• B. I – Dual Opening; II – Branched; III – Forked; IV – Splayed
• C. I – Dual Opening; II – Splayed; III – Forked; IV – Branched
• D. I – Branched; II – Dual Opening; III – Splayed; IV – Forked

Hint:

Understanding multilateral wellbore designs is key for reservoir management. Different wellbore configurations are used depending on the reservoir's characteristics and the desired production rate.

Answer 1

The Correct Option is B

In multilateral well patterns, the shape and orientation of the wellbore branches are critical for identifying the type of well pattern.
- Pattern I is a Dual Opening well, characterized by two openings from the main wellbore.
- Pattern II is a Branched well, where multiple branches extend from the main wellbore in a uniform direction.
- Pattern III is a Forked well, with a central main wellbore that divides into two forks.
- Pattern IV is a Splayed well, where multiple branches extend from the main wellbore at different angles, resembling a splayed shape. Thus, the correct identification of the well patterns is: \[ I – {Dual Opening}; II – {Branched}; III – {Forked}; IV – {Splayed} \] This corresponds to option (B).
