Interactive Test of Well Damage Simulator (WDS)

Explore, experiment, and learn with the Well Damage Simulator’s test of functionality. This interactive experience serves as a gateway to understanding the broader aspects of well operations and the complex balance required to maintain well integrity and productivity. Enjoy your journey through the virtual drilling of Well X-15 and see firsthand the effects of your decisions on its output!

Welcome to the Interactive Test Functionality of WDS


Dive into the world of drilling operations with our Well Damage Simulator (WDS). This page is designed as an interactive test functionality segment of WDS, providing a simplified but insightful environment for users to explore key aspects of drilling dynamics without the complexity of full operational parameters.

The Scenario: Virtual Drilling Operation at Well X-15


Embark on a virtual drilling experience with Well X-15, a completely fictional vertical well drilled to a depth of 3,015 meters using water-based mud while over-balanced drilling. The undamaged formation, characterized by Productivity Index of 26, porosityof 15% and 83 mD permeability, and a reservoir pressure of 5161 psi, sets the stage for your interactive exploration.  

Learning Objective


This interactive test functionality of WDS is intended to give you a practical understanding of how specific changes in drilling fluid properties and pressure management can affect well performance. While the full capabilities of WDS include many more variables, this page offers a focused environment to understand the basic principles and impact of formation damage on well productivity.

Control and Experimentation


In the real-world drilling operations, engineers have control over numerous parameters to optimize the drilling process and minimize the impact on the formation. In this simplified version of WDS, you will focus on two critical aspects:

Solid Percentage in Drilling Fluid: Adjust the concentration of solid particles in the mud, which can influence the blockage of pore spaces and potentially affect the formation’s permeability.

Pressure Difference: Manage the differential between the bottomhole pressure and the reservoir pressure. This balance is essential to ensure effective drilling while preventing excessive fluid invasion into the formation.

Interactive Simulation Outputs


After setting your desired parameters and initiating the simulation with the “Run Simulation” button, you will see:

Skin Factor vs Time: A graph depicting how the skin factor evolves over time, providing insights into the level of formation damage caused by mud invasion into the formation.

Productivity Index vs Time: A chart showing the productivity index, which measures the well’s ability to produce fluids under the conditions you’ve set.
