RODSTAR-V 3.2

RODSTAR-V is a specialized engineering application for designing, simulating, and optimizing sucker-rod (rod-lift) pumping systems in oil and gas wells. It helps production engineers and artificial-lift specialists model both surface and downhole dynamics, evaluate equipment choices, and improve well performance while managing mechanical risk and power consumption.

Key capabilities:

• Build and optimize tapered rod strings; select grades and sizes to meet load, stress, and fatigue criteria.
• Simulate surface unit performance, counterbalance, and motor loading across a range of operating speeds.
• Predict downhole behavior, including pump fillage, fluid production, and gas interference effects.
• Generate and interpret diagnostic plots such as surface and downhole dynamometer cards.
• Run what-if scenarios to balance production targets with equipment life and energy use.
• Produce clear, configurable reports for design reviews and field execution.

Typical uses:

• New well rod-string design and equipment sizing.
• Troubleshooting high-failure wells using diagnostic modeling.
• Evaluating variable-speed operation and pump-off control strategies.
• Field development workflows that require consistent, auditable designs and documentation.

Benefits:

• Reduces trial-and-error in the field by validating designs before deployment.
• Extends equipment life by keeping stresses within recommended limits.
• Improves production efficiency through informed speed and counterbalance adjustments.
• Streamlines collaboration between office engineers and field teams with shareable, standardized outputs.
