Chen. "Step Changes needed to Modernise T this means that the pipe is treated as a heavy cable, chain or rope lying along the wellbore. This means that axial tension and torque forces are supported by the string and contact forces are supported by the wellbore.This model assumes that the loads on the string result solely from the combined effects of gravity and frictional drag; a result of contact between the string and the wellbore. The frictional force is simply the product of the normal force acting between the string and wellbore and the coefficient of friction. The schematic in Figure 1 illustrates the forces acting on a single drillstring element.
