1. A method, comprising:

  • establishing fluid connectivity between a wellbore and a first target zone, and between the wellbore and a second target zone, wherein the first target zone and second target zone comprise zones for treatment within a subterranean formation intersected by a wellbore, wherein the second target zone is above the first target zone;

    positioning a coiled tubing into the wellbore;

    performing a first treatment step on the first target zone, wherein the first treatment step comprises contacting a treated zone with a treatment fluid;

    performing a second treatment step on the first target zone, wherein the second treatment step comprises introducing a diversion agent comprising a degradable material to the treated zone;

    performing the first treatment step on the second target zone;

    degrading the diversion agent after the performing the first treatment step on the second target zone; and

    measuring a wellbore parameter wherein measuring comprises measuring microseismic activity.
