System and method for fracturing and gravel packing a borehole

A method of fracturing and gravel packing a borehole in an earth formation, comprising:

• positioning a completion string in a borehole, the completion string having at least one filter assembly adapted to filter entry of particulate from an exterior of the completion string into an interior of the completion string and having at least one fracturing sub;
• sealing an annulus between the completion string and the borehole;
• flowing a gravel packing slurry around the at least one filter assembly into the annulus between the completion string and the borehole via a passage between the seal and the filter assemblies;
• fracturing the earth formation with the at least one fracturing sub;
• and
• producing fluids from the earth formation through the completion string.

A method of fracturing an earth formation, comprising:

• positioning a completion string in a borehole;
• gravel packing an annulus between the completion string and the borehole through a crossover valve having an passage to the annulus;
• and
• without removing the completion string, fracturing the earth formation in a plurality of axial positions.

A method of fracturing earth formation, comprising:

• positioning completion string in a borehole;
• gravel packing an annulus between the completion string and the borehole through a crossover valve having an passage to the annulus;
• without removing the completion string, fracturing the earth formation;
• producing fluids from the earth formation through the completion string;
• ceasing production of fluids from the earth formation;
• and
• without removing the completion string, fracturing the earth formation again.

A method of fracturing an earth formation, comprising:

• positioning a completion string in a borehole;
• gravel packing an annulus between the completion string and the borehole through a crossover valve having an passage to the annulus;
• without removing the completion string, fracturing the earth formation;
• and
• wherein fracturing the earth formation comprises introducing fracturing fluid into a fracturing sub and directing, the fluid to fracture the earth formation.
