SROD 9.1: Rod Pump Design & Predictive Software
SROD is LUFKIN Industries’ intelligent rod pump design software, the industry standard for designing, predicting, and optimizing sucker rod pumping systems in vertical, deviated, and horizontal wells . It uses a proprietary wave equation algorithm that accounts for rod dynamics, viscous and drag friction, buckling tendency, and three-dimensional wellbore trajectories .
Version Context
The search results do not contain specific release notes for SROD 9.1. However, the documented release timeline shows that version 9.0.0 was released in September 2024, and version 9.2.0 was released in October 2025 . This suggests that 9.1 was likely an interim release between those versions, containing incremental improvements and bug fixes rather than the major features introduced in 9.0 and 9.2.
Core Capabilities (Consistent Across 9.x Series)
| Feature | Description |
|---|---|
| Multi-Case Generation Wizard | Automatically generates multiple well design scenarios based on user-defined criteria; compares cost, uptime, energy, and output to identify optimal configurations in minutes |
| 3D Wellbore Viewer | Upload deviation surveys to model wellbore configuration; display rod tapers, pump, anchor, and perforations; analyze drag, side loads, buckling, and dogleg severity |
| Counterbalance/CBAL Tool | Calculates required counterweight amount and correct crank location for optimal pumping unit balance |
| Rod Guide Design | Automatically determines guide placement and quantity based on real dynamic side loads and buckling tendency |
| Deviated Well Analysis | Handles 3D borehole trajectories with rod/tubing drag friction—critical because applying vertical-well methods to deviated wells causes substantial design errors |
| Extensive Equipment Database | Includes pumping units, cranks, rods, motors, and guides with frequent updates |
