RodSim
RodSim Overview
Design and simulate rod pump systems in the cloud
RodSim is PetroBench's rod pump simulation application. Design rod strings, analyze stress and fatigue, compare configurations, and export reports, all from your browser.
Features
Cloud Simulations
Run simulations from any browser with results in seconds. No software to install.
Design Comparison
Compare up to five rod pump designs side-by-side.
3D Wellbore Viewer
Visualize wellbore geometry, stress zones, and rod loading in 3D.
Legacy Import
Import RodStar and SRod files directly.
How It Works
Configure Your Well
Enter directional survey, tubing, and casing data, or import from your well database.
Design Rod String
Select rod tapers, grades, and lengths. Configure pump and pumping unit.
Run Simulation
Execute simulation to calculate loads, stresses, and production estimates.
Analyze and Compare
Review results, clone simulations to test alternatives, and compare designs.
What RodSim Calculates
| Output | Description |
|---|---|
| Rod Stress | Stress at every point along the rod string |
| Pump Fillage | Percentage of pump barrel filled with fluid |
| Polished Rod Load | Surface load and torque requirements |
| Fatigue Life | Estimated rod life based on modified Goodman |
| Buckling | Rod buckling tendency and critical loads |
Getting Started
Directional Surveys
Import and manage wellbore trajectory data in PetroBench. Upload directional survey files, visualize well paths, and use survey data in rod pump simulations.
Creating a Simulation
Create a new RodSim rod pump simulation in PetroBench. Select a well, choose equipment, and configure operating parameters to start your analysis.
