FAQ
What does the Bowen Casing Spear Calculator do?
The Bowen Casing Spear Calculator determines the overall load rating and mode of failure for the spear, mandrel, grapple, and casing in an application. It models the entire system, incorporating feedback from field experience, lab testing, and FEA models for comprehensive analysis.
How accurate are the calculations provided by Bowen Casing Spear Calculator?
Calculated values are theoretical yield strengths and are considered accurate to within +/-20%. These calculations assume the worst-case scenario based on API tolerance and straight, steady pulling of a fully engaged round fish.
Does the Bowen Casing Spear Calculator consider API tolerances?
Yes, the app considers the catch range for the Grapple as well as API tolerances per API Specification 5CT. It always takes the worst-case scenario as the maximum pull value, which results in the lowest contact between the Grapple and Mandrel Helix.
What assumptions are made by the Bowen Casing Spear Calculator?
Important assumptions include considering the grapple's catch range and API tolerances, always taking the worst-case scenario for maximum pull, and that ratings are only valid if the fish is within the grapple's catching range. Casing ID is calculated based on OD and Weight if those are manual inputs.
What factors can reduce the strength calculated by Bowen Casing Spear Calculator?
Irregularities in the fish ID/OD, damage to the grapple or mandrel, or jarring can substantially reduce the calculated strength. The ratings are based solely on the Grapple range and are presented without any safety factor.
Is the Bowen Casing Spear Calculator available on multiple devices?
The Bowen Casing Spear Calculator is available for iPhone, iPad, and iPod. It was released on August 3, 2019, and last updated on December 8, 2022, with version 1.1.
What is the age rating for the Bowen Casing Spear Calculator?
The Bowen Casing Spear Calculator has an age rating of 12+. This indicates it is suitable for users aged 12 and older.
Does the Bowen Casing Spear Calculator have ads?
No, the Bowen Casing Spear Calculator does not contain advertisements. It is a free application without any in-app purchases or ads.
