Methods for stabilizing water sensitive clays and migrating fines in subterranean formations

A method comprising:

• injecting, into a subterranean formation under fracturing conditions, one or more first fracturing fluid compositions comprising:
• a first base fluid;
• one or more first synthetic and/or natural hydratable polymers;
• one or more first crosslinking agents;
• and
• an effective amount of a clay stabilizing composition;
• injecting, into a subterranean formation under fracturing conditions, one or more second fracturing fluid compositions comprising:
• a second base fluid;
• one or more second synthetic and/or natural hydratable polymers;
• one or more second crosslinking agents;
• one or more proppants;
• and
• an effective amount of the clay stabilizing composition,
• wherein:
• the clay stabilizing composition comprising:
• one or more tri-functional primary amine compounds comprising one or more compounds of Formula I:
• HC(RNR1R2)(R′NR3R4)(R″NR5R6) (I);
• and
• one or more salts comprising one or more compounds of Formula II:
• HC(RN+R1R2R7)(R′N+R3R4R8)(R″N+R5R6R9)Xn (II),
• the R, R′, and R″ groups comprising the same or different hydrocarbyl linking groups including between 1 and 8 carbon atoms, and when the R, R′, and R″ groups including between 2 and 8 carbon atoms, then one or more carbon atoms may be replaced by acetate groups, or carbonyl groups,
• the R1-6 groups comprising the same or different hydrogen atoms or hydrocarbyl groups including between 1 and 6 carbon atoms, and when the R1-6 groups including between 2 and 6 carbon atoms, then one or more carbon atoms may be replaced by oxygen atoms, acetate groups, or carbonyl groups,
• the R7-9 groups are (a) absent and their associated nitrogen atoms do not bear a charge, (b) the same or different comprising a hydrogen atom and their associated nitrogen atoms bear a charge, or (c) the same or different comprising a hydrocarbyl group including between 1 and 24 carbon atoms and their associated nitrogen atoms bear a charge;
• provided that at least one of the R7-9 groups comprising a hydrogen atom or a hydrocarbyl group, and when the R7-9 groups including between 2 and 24 carbon atoms, then one or more carbon atoms may be replaced by oxygen atoms, acetate groups, or carbonyl groups;
• the X groups are the same or different counterions derived from an organic acid, an alkylating agent, a quaternizing agent, or mixtures thereof;
• n is an integer having a value of 1, 2 or 3;
• provided that each of the compounds of Formula (II) is neutral;
• the clay stabilizing composition stabilizes clay, reduces clay swelling, and reduces fines migration during fracturing.
