Through the analysis o f dam age m echan ism to hydraulic
fractures in gas-condensate reservoirs, we a re presen ting a
m ode l that pred icts the fractured we ll pe rfo rm ance in gascondensate
rese rvo irs,l and quan tify ing the effec ts of
perm eab ility reduc tion. Furtherm o re, we present fracture
treatment design for condensate reservoirs. The distinguish ing
feature pr im arily affec ts the requ ired frac ture leng th to offset
