Summary Field drill-off test results are compared with data from laboratory simulations. A simple theory for analyzing drill-off tests is developed. The weight-on-bit (WOB) decay with time is close to exponential, but large threshold WOB's, resulting from poor weight transmission downhoie, are sometimes observed in field tests.
