Mr. John R. Mastandrea |
| Contracting Agency |
Naval Ocean Systems Center |
| Estimated Completion |
Complete |
| Description |
Investigation of techniques for
measuring casing wall thickness. |
| Progress |
Complete. This study concluded
that casing inspection is used when serious degradation is suspected. The technology for
using NDE methods as a diagnostic tool during normal drilling operations is available.
Development of a combined acoustic emission/hydrostatic inspection method is recommended
as a practical, low cost technique. |
