Abstract
Abstract A method for diverting resins and other treating fluids used for sand control in wells drilled through unconsolidated subterranean formations is provided. Explosives placed in the wellbore in proximity to the treating solutions are actuated to divert the solutions through all perforations in the casing of the well and allow sand-free production of fluids through the well.

Claims Analysis
Total Claims: 24
Claim 1
Independent Claim
97 words
A method for treating a well having perforated casing to prevent solids movement through the perforations and into the wellbore comprising: (a) positioning a quantity of liquid resin solution such that the solution occupies the interval of the casing having perforations; (b) positioning an explosive in proximity with the liquid resin solution; (c) detonating the explosive; (d) displacing the liquid resin solution remaining in the wellbore after step (c) through the perforations with a displacing fluid; and (e) injecting a chemical solution through the perforations to cause the resin to polymerize to form a consolidated permeable matrix.
Claim 2
Independent Claim
97 words
A method for treating a well having perforated casing to prevent solids movement through the perforations and into the wellbore comprising: (a) positioning a quantity of liquid resin solution such that the solution occupies the interval of the casing having perforations; (b) positioning an explosive in proximity with the liquid resin solution; (c) detonating the explosive; (d) displacing the liquid resin solution remaining in the wellbore after step (c) through the perforations with a displacing fluid; and (e) injecting a chemical solution through the perforations to cause the resin to polymerize to form a consolidated permeable matrix.
Claim 3
Dependent Claim
23 words
The method of claim 1 wherein the resin is selected from the group of resins consisting of furan, phenolic-furfuryl, phenolic, phenol-formaldehyde and epoxy.
Claim 4
Dependent Claim
19 words
The method of claim 1 wherein the explosive is in the form of a cord comprising an explosive material.
Claim 5
Dependent Claim
33 words
The method of claim 1 wherein an explosive is actuated two or more times in proximity with the liquid resin solution while the resin solution occupies the interval of the casing having perforations.
Claim 6
Dependent Claim
33 words
The method of claim 1 wherein an explosive and a gas generator are actuated in proximity with the liquid resin solution while the resin solution occupies the interval of the casing having perforations.
Claim 7
Dependent Claim
32 words
The method of claim 1 wherein an explosive is placed in proximity with the displacing fluid of step (d) and actuated while the fluid occupies the interval of the casing having perforations.
Claim 8
Dependent Claim
34 words
The method of claim 1 wherein an explosive and a gas generator are actuated in proximity with the displacing fluid of step (d) while the fluid occupies the interval of the casing having perforations.
Claim 9
Dependent Claim
34 words
The method of claim 1 wherein an explosive charge is placed in proximity with the chemical solution of step (e) and actuated while the chemical solution occupies the interval of the casing having perforations.
Claim 10
Dependent Claim
36 words
The method of claim 1 wherein an explosive and a gas generator are placed in proximity with the chemical solution of step (e) and actuated while the solution occupies the interval of the casing having perforations.
Claim 11
Dependent Claim
33 words
The method of claim 1 further comprising actuating a perforating gun to form additional perforations in the casing after step (c) and before step (d) and subsequently repeating steps (a), (b) and (c).
Claim 12
Dependent Claim
27 words
The method of claim 1 further comprising adding a particulate diverting agent to the chemical solution of step (e) before the solution is placed in the well.
Claim 13
Dependent Claim
19 words
The method of claim 1 wherein the near-wellbore region is pre-packed with sand or other particles before step (a).
Claim 14
Independent Claim
128 words
A method for treating a well having perforated casing to prevent solids movement through the perforations and into the wellbore comprising: (a) positioning a quantity of liquid resin solution such that the solution occupies the interval of the casing having perforations, the resin solution comprising a chemical to cause the resin to polymerize; (b) positioning an explosive in proximity with the liquid resin solution; (c) detonating the explosive; (d) displacing the liquid resin solution remaining in the wellbore after step (c) through the perforations with a displacing fluid and injecting the displacing fluid through the perforations to reduce the saturation of resin solution in the formation, the displacing fluid being immiscible with the resin solution; and (f) allowing the resin to polymerize to form a consolidated permeable matrix.
Claim 15
Independent Claim
128 words
A method for treating a well having perforated casing to prevent solids movement through the perforations and into the wellbore comprising: (a) positioning a quantity of liquid resin solution such that the solution occupies the interval of the casing having perforations, the resin solution comprising a chemical to cause the resin to polymerize; (b) positioning an explosive in proximity with the liquid resin solution; (c) detonating the explosive; (d) displacing the liquid resin solution remaining in the wellbore after step (c) through the perforations with a displacing fluid and injecting the displacing fluid through the perforations to reduce the saturation of resin solution in the formation, the displacing fluid being immiscible with the resin solution; and (f) allowing the resin to polymerize to form a consolidated permeable matrix.
