Abstract
A method of mapping micro-fractures of a fracture network comprising: introducing a capsule or coated capsule or containment into the fracture network, where in the capsules or containment comprise an explosive substance and a plurality of micro-proppant; allowing initiation of the explosive substance of some or all of the plurality of the capsules to occur, wherein initiation of the explosive substance causes detonation of the explosive substance, and wherein the detonation produces one or more micro-seismic events; and causing or allowing at least a portion of the micro-proppant to enter one or more of the micro-fractures.
Claims22
A method of mapping micro-fractures of a fracture network comprising:
- introducing a capsule into the fracture network, wherein the capsule comprises an explosive substance, a core, a coating, an intermediate layer, and a plurality of micro-proppant;
- wherein the intermediate layer is positioned between the core and the micro-proppant or the core and the coating;
- wherein the intermediate layer comprises an initiator for initiating the explosive substance;
- wherein the intiator comprises a water-sensitive explosive material that reacts with water to initiate the explosive substance;
- allowing initiation of the explosive substance to occur, wherein initiation of the explosive substance causes detonation of the explosive substance, and wherein the detonation produces one or more micro-seismic events;
- and
- causing or allowing at least a portion of the micro-proppant to enter one or more of the micro-fractures.
A method of mapping micro-fractures of a fracture network comprising:
- introducing a coated capsule into the fracture network, wherein the coated capsule comprises an explosive substance, a core, an intermediate layer, and a plurality of micro-proppant;
- wherein the intermediate layer is positioned between the core and the micro-proppant or the core and the coating;
- wherein the intermediate layer comprises an initiator for initiating the explosive substance;
- wherein the initiator comprises a water-sensitive explosive material that reacts with water to initiate the explosive substance;
- allowing initiation of the explosive substance to occur, wherein initiation of the explosive substance causes detonation of the explosive substance, and wherein the detonation produces one or more micro-seismic events;
- and
- causing or allowing at least a portion of the micro-proppant to enter one or more of the micro-fractures.
A method of mapping micro-fractures of a fracture network comprising:
- introducing a containment of an explosive substance, a core, a coating, an intermediate layer;
- and a plurality of micro-proppant into the fracture network;
- wherein the intermediate layer is positioned between the core and the micro-proppant or the core and the coating;
- wherein the intermediate layer comprises an initiator for initiating the explosive substance;
- wherein the initiator comprises a water-sensitive explosive material that reacts with water to initiate the explosive substance;
- allowing initiation of the explosive substance to occur, wherein initiation of the explosive substance causes detonation of the explosive substance, and wherein the detonation produces one or more micro-seismic events;
- and
- causing or allowing at least a portion of the micro-proppant to enter one or more of the micro-fractures.
A capsule for mapping micro-fractures of a fracture network comprising:
- an explosive substance;
- a core;
- a coating;
- a plurality of micro-proppant;
- and
- an intermediate layer positioned between the core and the micro-proppant or the core and the coating;
- wherein the intermediate layer comprises an initiator for initiating the explosive substance;
- and wherein the initiator comprises a water-sensitive explosive material that reacts with water to initiate the explosive substance.
