This program determines the maximum amount of overpull that can be applied to drill pipe or casing. It also gives the derated tensile strength of the pipe at the surface and at a dogleg. This program calculates the free point of a string of drill pipe or casing using actual stretch data gathered on the rig. This program is based on the Paslay-Bogy analysis for pipe buckling in inclined holes. The program calculates the air weight and usable weight for a given BHA, then designs a BHA optimized for hydraulics.
Tubular designs can be computer generated or input by user.
Tubular items in the database may be limited to a specified available quantity. Tri-axial stress analysis can be performed for both burst and collapse. Collapse bi-axial adjustment model can be selected. Real Gas Law Analysis for Internal Burst Load Modeling. Internal burst gradients can be input directly or calculated based on gas gravity.
