RODSTAR offers both vertical and horizontal well operators a powerful tool to design optimized pump configurations and simulate future pump performance. The advanced calculation engine in RODSTAR guides you through a series of steps to collect configuration data about your pump design. After the inputs have been collected, it performs complex calculations that model the performance of the design. This performance is documented in a comprehensive report that grades the design's attributes and provides itemized design improvement recommendations.

  • Input Steps

    RODSTAR offers both vertical and horizontal well operators a powerful tool to design optimized pump configurations and simulate future pump performance. The advanced calculation engine in RODSTAR guides you through a series of steps to collect configuration data about your pump design. After the inputs have been collected, it performs complex calculations that model the performance of the design. This performance is documented in a comprehensive report that grades the design's attributes and provides itemized design improvement recommendations.

    • Step One > Well Information:

      RODSTAR collects vital well details such as Well Name, Pump Condition, Tubing Pressures, Pump Depth, and Fluid Profile.

    • Step Two > Set Production Targets:

      While traditional design software has used Strokes Per Minute (SPM) to guide designs, RODSTAR allows you to specify the Barrels of Fluid Per Day (BFPD) as the design target for your design. This reduces the “trial and error” work required to design an optimized pumping unit. Additionally, RODSTAR allows you to use standard inflow performance algorithms (i.e. Vogel, Fetkovich) to derive design targets.

    • Step Three > Design the Plunger:

      RODSTAR will automatically select the correct plunger size based on the tubing size that you specify.

    • Step Four > Building the Rod String:

      RODSTAR helps you design the perfect rodstring. The manual configuration screen allows you to specify the individual components of the rodstring, based on what rods you have available. Manual design is helpful for optimizing a well with existing equipment. The auto-design functions will craft the perfect rodstring for you. RODSTAR’s advanced modeling can design steel, fiberglass, or carbon fiber rodstrings. Auto-calculation is helpful for new pump designs.

    • Step Five > Deviated Wells:

      RODSTAR can help design both deviated and horizontal wells. For deviated wells, RODSTAR allows you to specify your own rod-guides or you can have RODSTAR design the correct rod-guide and taper combinations. RODSTAR calculates and graphs rodstring, allowing you to precisely visualize the geometry of the rodstring.

    • Step Six > The Perfect Pump:

      RODSTAR has a database of over 40,000 pumping units. This vast database is used to search for the optimal pumping unit for a design. Conversely, RODSTAR can help you build the optimal design around an existing pumping unit. RODSTAR can simulate any pumping unit, including long stroke (Rotaflex) or hydraulic units.

    • Step Seven > Optimize Energy Usage:

      RODSTAR’s motor selection starts with the cost of electricity. This cost is used to guide its calculations toward the optimal energy usage profile. This profile can include non-standard process variables such as whether utility credits are received for generated power and electric motor speed variation.

  • Simulation Outputs
    • System Design Score:

      RODSTAR provides a summary of the design by assigning a grade from A+ to F. It then breaks down the designs performance into categories and assigns 1 to 100 scores for each category.

      These categories include:

      • Balanced Gearbox Loading: Is the size of the Gearbox sufficient to handle the weight of the rodstring?
      • Maximum Rod Loading: Are the rods being stressed passed their allowed performance profile?
      • System Efficiency: Is the system wasting energy?
      • Bottom Minimum Stress: Are sinker bars properly distributed along the rodstring?
    • Calculations:

      RODSTAR, at its heart, is a complex and precise calculator. The most advanced Rod Pump calculator in the industry. The calculations report provides the input/output values of the dozens of variables and coefficients that RODSTAR uses to simulate well performance.

    • Equipment Cost:

      RODSTAR analyzes the position of rod guides along the rod string, determines side loads, then provides recommendations for how rod guides should be positioned along the rodstring in order to increase optimization.

    • Dynamometer Cards:

      RODSTAR, at its heart, is a complex and precise calculator. It is the most advanced Rod Pump calculator in the industry. The calculations report provides the input/output values of the dozens of variables and coefficients that RODSTAR uses to simulate well performance.

    • Rod Velocity:

      RODSTAR’s simulations can predict if and when a design can expect “fluid pound” by using polished rod and plunger velocity plots.

    • Deviation Survey:

      For deviated wells, RODSTAR calculates the side load for each taper in the rodstring. This provides precise data on how guides should be positioned along the rod string.

    • Rod Guide Analysis:

      RODSTAR analyzes the position of rod guides along the rod string, determines side loads, then provides recommendations for how rod guides should be positioned along the rodstring in order to increase optimization.
