(petroleum engineering)

Formation fracturing pressure can be estimated using the following equation (Hubbert, 1957):
25, the formation fracturing pressure gradient (computed using Equation 13) equals to 0.
During pipe trip-in, large hole diameter provides bigger passage area for the mud, therefore, the piston-cylinder action acting opposite to the formation is minimized and the formation fracturing can be avoided as shown in Figure 6 (Hole size).
