Swab arid surge pressures, caused by moving the drillstring axially, can be calculated by a method similar to that used for calculating annular circulating pressures (Section 7). The greatest problem is determining fluid flow-rate in the annul us when the pipe is open-ended since the distribution of flow between pipebore and annulus cannot be found by ...
