Combined results for NPV and maximum encountered pore pressure difference as a function of FWD, flowrate and fault permeability. Both the highest and lowest injection temperature are considered. The horizontal lines show the pore pressure for failure-criterion exceedance assuming friction coefficients of 0.15, 0.17, 0.19 and 0.12, 0.14, 0.16 for the injection temperature of 303.15 K and 313.15 K respectively
