What This Document Is
This document contains the solution set for Homework Five assigned in Petroleum Reservoir Engineering I (PEGN 423) at the Colorado School of Mines, Fall 2019. The assignment focuses on water influx calculations in oil reservoirs, a critical aspect of reservoir performance forecasting. It’s intended for students to check their work and understand the correct application of reservoir engineering principles.
Why This Document Matters
This solution set is valuable for students enrolled in PEGN 423 who completed Homework Five. It provides a benchmark for understanding the concepts of water influx, Schilthuis’ equation, and steady-state/transient water drive models. It’s used after individual attempts at the homework to verify understanding and identify areas needing further review.
Common Limitations or Challenges
This document provides *solutions* to specific problems, but it does not offer detailed explanations of the underlying theory or derivations of the equations used. Students still need to understand the fundamental concepts from lectures and textbooks to fully benefit from the solutions. It does not substitute for completing the assignment independently.
What This Document Provides
The full document includes:
* Complete, worked solutions for three problems related to water influx calculations.
* Calculations for Schilthuis’ water influx constant.
* Cumulative water influx calculations using the steady-state model.
* Water influx calculations using the van Everdingen-Hurst and Carter-Tracy methods.
* Numerical results and plots illustrating the calculated water influx over time.
This preview does *not* include the detailed step-by-step calculations or the plots themselves. It only describes the content available within the complete solution set.
