| Description |
The purpose of the project was
to improve the accuracy of casing collapse performance properties. This
improvement may allow an opportunity to substantially reduce tubular costs,
because the margins of actual collapse performance versus API ratings have
been found to be as high as 30-40%. The JIP conducted physical testing on
industry-wide sampling of API and proprietary casing grades and reviewed
mill production techniques for both API and proprietary grades of casing.
Data was analyzed so that participating operators may be able to reduce
tubular costs. Database was provided to API and ISO for future
standardization activity. The JIP was completed in October 2002. |
