Rodstar will inspect the rod to determine if the breakage was due to workmanship or material defect.įor breakage determined to have occurred due to defect, Rodstar will, at the company’s discretion, either repair or replace the product for a Handling Fee of $30.00 (US).įor breakage deemed to be the result of anything other than defect, at the company’s discretion, will be repaired or replaced for a specific fee. Our artificial lift experts use pump-tracking software (RODSTAR, SROD) and decades of practical experience to calculate optimum rod string design and help. This warranty does not cover fire, theft, loss, intentional and/or accidental breakage, modification or customization of the finished rod. It does not cover direct, indirect, consequential, incidental, accidental, negligence, normal wear and tear, or any other type of damage resulting from the use of the product. This warranty is limited to repair or replacement of the rod at our discretion. The rod must be registered with Rodstar within 30 days of purchase for any warranty claim to be considered. These increases power consumption but reduces the required pumping unit gearbox size.Rodstar rods are covered by a Limited Lifetime Warranty against defects in workmanship and materials for the life of the original registered owner. On the other hand, a smaller pump demands a faster pumping speed or longer stroke to make the desired production. Also, a large pumping unit must be used and this will increase capital cost. However, a large pump will increase rod loading and gearbox torque. If electricity cost is high, it can be lowered by using a larger pump and a slower pumping speed. In most cases production rate is of highest priority, followed by rod loading, gearbox loading, and energy cost. However, because of the data, expertise, and time required to achieve this goal with conventional rod pump design software, most system designs are far from ideal. Ideally, the designed system will give the highest present value profit after tax, considering capital and operating costs. In an effort to select the best system design for a well, the designer is mostly concerned with the following parameters: When designing a rod pumping system one must specify the equipment, strokes per minute, and stroke length required to get the desired production at the lowest possible cost. It is estimated that with RODSTAR the average user can obtain working rod pumping system designs ten times faster than with conventional non-expert computer programs. One of RODSTAR's unique capabilities is modeling pumping systems for shallow, high rate wells. It also calculates energy consumption, electricity cost per barrel of produced fluid, and can model low or high slip prime movers.

The program ensures that the fiberglass rods are not in compression and avoids designs with excessive rod stretch.

When designing a fiberglass rod string RODSTAR calculates the length of the bottom steel section and selects the appropriate diameter and length of the fiberglass portion. When designing a steel rod string, RODSTAR "decides" what rod taper is needed and automatically calculates the length of each section for equal stress loading. RODSTAR can automatically design steel or fiberglass rod strings. A context sensitive expert help system warns the user of rods that need slim hole couplings, pump sizes that are too big for the tubing, pumping speeds that are too high, or designs that may result in severe under travel. RODSTAR includes a large pumping unit data base and is completely menu driven. Although expert users can enter their own designs, taking advantage of the program's expert capabilities minimizes the time and expertise required to design rod pumping systems.

Unlike conventional rod pump system design programs that rely on a trial and error approach, RODSTAR can automatically calculate the strokes per minute (spm), plunger size, and rod siring design to obtain the "target" production entered by the user. RODSTAR can simulate steel or fiberglass rods and any pumping unit geometry including long stroke non-beam pumping units. RODSTAR combines expert rod pumping knowledge with state-of-the-art wave equation and pumping unit modeling algorithms.

A "smart" predictive computer simulator of rod pumping systems called RODSTAR has been developed.
