The Tylan Plot (or Tylan Bucket Method) is used to monitor hole cleaning during drilling operations.

During drilling, cuttings of the drilled formation are removed from the hole by pumping fluid through the drillstring, and back up the annulus. It is important that all of these cuttings are removed so they do not impede future operations. The Tylan method involves measuring the rate of cuttings coming over the shakers, once total depth (TD) has been reached and the TD clean up commences. The cuttings are measured by weight and collected over a set period of time (usually 1 minute). A bucket or similar device is used to collect the cuttings, and then they are weighed.

The results are plotted with time, and a trend can be established to determine how clean the well is. The cleanliness of the well is usually judged visually by the wellsite manager and mud engineer. The Tylan method provides a quantitative means of judging the cleanup trend. See example plot below.
