Rod Data

Row Quantity

Allows the user to select the number of tapers making up the rod string.

Row Type

The user can select between Branded, Measured, or Create Measured. Selecting Branded allows them to select from a list of manufacturers, associated grades and diameters from the rod library. Selecting measured will allow the user to select a rod from a list of measured rods previously defined by the user of their associated company. Selecting Create Measured allows the user to define a measured rod to be used in the current simulation, and stored for future use.

Rod Type

The user can select between “Sucker Rod”, “Sinker Bar”, “Fiberglass”, and “Continuous”. The options for Manufacturer are populated based on the selection for “Rod Type”.

Manufacturer

The user can select between from a list of Manufacturers that have available rods based on the “Rod Type” selection.

Grade

The user can select between from a list of available grades for the selected manufacturer.

Diameter

The user can select between from a list of available diameters based on the manufacturer and grade selected.

Stress Calculation

The stress calculation method is populated based on a default, but the user can change it.

Guided

If the rod taper associated with a row is guided, they check the box.

Guide Type

The user can select from a list of branded guides from the “Guide Type” selection window.

Guides Per Rod

Users enter the number of guides per rod for each taper.

Friction Coefficient

The friction coefficient is populated with a default based on the rod and guides, but is editable.

Length

The user enters the length of each of the rod tapers, the bottom taper length is calculated based on the above taper lengths and the PSN depth.

Polished Rod Diameter

The user selects the polished rod diameter from a list.

Steel Rod Service Factor

A stress load derating factor based on fluid conditions.

Calculate Guides Per Rod

Selecting will calculate the optimal number of guides per rod so that the maximum recommended side force per guide is not exceeded, and the distance between guides does not exceed the critical buckling length for the specified taper.

Include Buoyant Guide Weight

Selecting will include the weight and buoyancy of the rod guides in the simulation calculations.

Design Assistance

Selecting allows the user to define general parameters of a rod string to automatically populate the input table, rather than manually creating a rod string.

Rod Material

The user can select between steel, continuous or fiberglass as the primary rod string material.

Rod Type

Like rod input table, the user can select from branded, measured, or can create a measured rod.

Manufacturer

The user can select between from a list of Manufacturers that have available rods based on the “Rod Type” selection.

Rod Grade Design

The user can select between from a list of available grades for the selected manufacturer.

Maximum Rod Diameter

Rod diameter of the top taper.

Minimum Rod Diameter

Rod diameter of the bottom taper.

Include Steel Below

If the user selects Fiberglass for the rod material, the include steel below selection will appear. Selecting allows the user to define steel rod tapers below the fiberglass taper.

Include Sinker Bars/Rods

Selecting allows the user to define a sinker rod or sinker bar taper below the already define rod tapers.

Sinker Type

The user can select between sinker bars and sinker rods; sinker rods are sucker rods used in a sinker application, that is when the diameter of the taper is larger than the diameter of the above taper.

Sinker Manufacturer

The user can select between from a list of manufacturers that have available sinker bars/rods for the sinker type selected.

Sinker Bar/Rod Grade

The user can select from a list of available grades for the selected sinker type and manufacturer.

Sinker Rod/Bar Diameter

The user selects from a list of available diameters for the type, manufacturer and grade selected.

Segment Length

The user enters the length of the sinker taper.

Create

Clicking on create will generate a rod string based on the design assistance inputs, and populate the rod table.
