The Well bore 102 is shoWn here cased With the casing 114, Which can be simply casing or a linear, cement, or cemented casing or a cemented liner or even uncased or open. After the formation has been conglomerated as shoWn in FIGS. 1A&B, the conglomerated formation 120 isproduced above itscriticaldraW doWn pressure as shoWn inFIG. 2A to produce a mixture 202. The mixture 202 includes, but isnot limited to, formation particulate of the conglomerated Zone 120. The co-production of the portion of the conglomerated Zone 120 forms a cavity or cavities 204 surrounding the Well bore 102 in the Zone 120 to form the cavitated, conglomer ated, producible Zone 206 as shoWn in FIG. 2B.

DETAILED DESCRIPTION OF THE DRAWINGS Referring noW to FIGS. 1A&B, an embodiment of a ?rst stepofthemethodandsystemofthisinvention,generally45 100, is shoWn to include a Well bore 102 into a formation 104 including a top Zone 106, a producible Zone 108 and a bottom Zone 110. The top Zone 106 and the bottom Zone 110 can be non-producible Zones or producible Zones Within the forma tion104,butarenotbeingsubjectedtotreatment.Optionally, 50 the producible Zone 108 is separated beloW by a packer or a plurality of packers 112. Ifthe Zone 106 is a producible Zone of the formation 104, then there could also be a packer or a pluralityofpackers(notshoWn)separatingtheproducibleor middleZone108fromthetopZone106.TheWellbore102is 55 shoWnheretoincludingcasing114,Wherethecasing114can be simply casing or a liner, cement, or cemented casing or a cemented liner. HoWever, the Well bore can also be uncased.

Although the embodiments of method and system of this invention can include only the ?rst three steps set forth pic torially in FIGS. 1A-3, the method and system can also include the step of consolidating or further conglomerating thecavitated,conglomeratedZone206asshoWninFIGS. 4A&B, generally 400.

FolloWing consolidation or further conglomeration, the consolidated or further conglomerated, cavitated producible Zone 404 is put or placed on production as shoWn in FIG. 5, generally 500, to produce hydrocarbons 502, Where the hydrocarbons 502 have reduced formation particulate, i.e., MSFR isincreased.
