| Description |
Synthetic-based drilling muds (SBMs)
have been developed to provide the desirable operating qualities of
oil-based muds with the lower toxicity of water-based muds. The objective of
this project was to evaluate the fall velocity distributions that would
result from an accidental release of SBMs in offshore waters. The
investigation focused on determining how fall velocity distributions for
SBMs used in Gulf of Mexico operations are affected by release conditions.
The project was organized into four tasks. Task 1 identified the SBM formulations now in use and collected data on SBM spills to date. Task 2 used limited modeling based on existing models to estimate fall velocities based on jet conditions and the SBM properties. Task 3 experimentally measured fall velocities produced in two idealized cases and Task 4 was the final report. |
