METHOD AND APPARATUS FOR TESTING SWELLABLE MATERIALS The invention provides a method and apparatus (50) for use in testing the swell characteristics of swellable components (34) used in downhole exploration or production equipment, such as swellable packers. A method of measuring a test piece (30) using a testing apparatus with a fluid chamber (54) and a transducer (70) is described. Measured data can be compared with data measured from a sample section of a tool to determine a relationship between swell characteristics. The determined relationships can then be used to calculate or predict swelling characteristics of swellable components, for example particular packer designs, in specific fluid samples. |
