Boundary Effects Analysis
Analysis of boundary effects on wellbore pressure. Compares infinite acting reservoir with single linear fault and perpendicular sealing faults.
Constant Pressure Boundary
Analysis of constant pressure boundary effects. Compares sealing boundaries with constant pressure boundaries (aquifer support).
Radial Flow Analysis
Infinite acting radial flow analysis using line source solution and vertical well models. Calculates dimensionless pressure for pressure transient interpretation.
Skin Factor Effect
Demonstrates the effect of skin factor on wellbore pressure. Positive skin indicates damage, negative skin indicates stimulation.
