Identify the CORRECT match for the flow regimes (Group 1) with the corresponding slopes of the pressure derivative (Group 2) used in the type curve analysis.
Show Hint
- I – P; II – Q; III – R; IV – S
- I – Q; II – S; III – R; IV – P
- I – R; II – S; III – Q; IV – P
- I – S; II – P; III – Q; IV – R
The Correct Option is C
Solution and Explanation
Step 1: Understand the flow regimes and their corresponding pressure derivative slopes.
- Spherical flow (I) has a pressure derivative slope of \( -\frac{1}{2} \), which matches with option (R). - Linear flow (II) has a pressure derivative slope of \( \frac{1}{2} \), which matches with option (S). - Bilinear flow (III) has a pressure derivative slope of \( \frac{1}{4} \), which matches with option (Q). - Boundary dominated flow (IV) has a pressure derivative slope of 1, which matches with option (P).
Step 2: Conclusion.
The correct matching of flow regimes to pressure derivative slopes is: I – R; II – S; III – Q; IV – P.
