Claim 0:
1. A payload deployment tool for insertion within an inner channel of a casing string of a wellbore, the payload deployment tool comprising:
a housing sized to slide within the inner channel of the casing string, the housing including:
an outer surface,
a coupler,
a pressure chamber, and
a plurality of payload chambers downstream of the pressure chamber,
each of the payload chambers having an upstream opening, a downstream opening terminating about a distal end of the housing, and an upstream pressure-rupturable seal covering the upstream opening, and a downstream pressure-rupturable seal covering the downstream opening; and

a plurality of payloads each comprising a solid, dissolvable material, each of the plurality of payloads disposed in one of the plurality of payload chambers and configured to be deployed into the wellbore;
wherein each upstream pressure-rupturable seal of the plurality of payload chambers has a unique pressure rating for rupturing upon application of a unique pressure thereto, and wherein each downstream pressure-rupturable seal has an equal pressure rating for rupturing upon application of the same pressure thereto;
wherein each of the plurality of payloads is formed as a solid capsule comprising the solid, dissolvable material and a chemical marker.
