In summary, the method involves (1) activating inflatable elements of the packer to isolate the formation to be tested; (2) using the rig pumps to pump seawater into the isolated formation in a controlled fashion, either as short (<1 min) pressure impulses for "slug tests" or at a constant rate for "injection tests" lasting tens of minutes; and (3) recording the pressure response in the isolated zone and at the rig floor. The pressure records can be interpreted to estimate average or "bulk" permeability of the isolated zone close to the borehole. In greater detail, the tools and methods employed were similar to those developed and applied during ODP, especially as described for Leg 139 (Shipboard Scientific Party, 1992b) and Leg 168 (Appendix of Becker and Fisher, 2000).
