Let's say I have an oil reservoir being waterflooded with a matrix of weakly consolidated sand. Now let's say I make the drawdown pressure too high and I sand up my wellbore and wreck my near wellbore permeability (possibly fines migration as well?). If I clean out my wellbore with coil, is there any frac I can pump that would bypass the damage of the sand invasion and keep the sand from invading my wellbore. I imagine the tail end of the frac would have a quick incremental ramp up of frac sand size to form a "gravel pack" behind pipe.
