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? \begin{center} \includegraphics[width=0.7\textwidth]{05.jpeg} \end{center}

• 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:

To identify multilateral well patterns, look at the symmetry and number of branches: Forked = 2 equal splits, Branched = uneven splits, Dual Opening = two outlets at the same junction, Splayed = multiple laterals spreading like a fan.

Answer 1

The Correct Option is A

Step 1: Pattern I.
Pattern I shows a simple split of the main bore into two nearly symmetrical laterals. This shape is typical of a Forked pattern. Step 2: Pattern II.
Pattern II shows two laterals emerging at different points on the main bore, with an asymmetrical branching style. This is a Branched pattern. Step 3: Pattern III.
Pattern III shows a lateral opening into the main bore at a single connection point, but the two appear as openings in parallel directions. This matches the definition of a Dual Opening pattern. Step 4: Pattern IV.
Pattern IV shows multiple laterals diverging from the main bore, resembling a fan-out or spread configuration. This clearly represents the Splayed pattern. Step 5: Matching with given options.
From the observations: - I = Forked - II = Branched - III = Dual Opening - IV = Splayed This matches option (A). Final Answer: \[ \boxed{\text{Option (A)}} \]
