Patent ID: 7228905

Claim:
A method of performing wellbore operations comprising: treating the wellbore with a composition comprising: (a) a zeolite having a mean particle size less than or equal to 100 microns, the zeolite being represented by the formula: M a/n [(AlO 2 ) a (SiO 2 ) b ]• x H 2 O where M represents one or more cations selected from the group consisting of Na, K, Mg, Ca, Sr, Li, Ba, NH 4 , CH 3 NH 3 , (CH 3 ) 3 NH, (CH 3 ) 4 N, Ga, Ge and P; n represents the cation valence; b:a ratio is in a range from greater than or equal to 1 and less than or equal to 5; and x represents number of moles of water entrained into the zeolite framework, (b) an activator in an amount of greater than or equal to 5% and less than or equal to 50%, by total weight of zeolite and activator, (c) an organic acid or salt thereof in an amount of greater than or equal to 0.1% and less than or equal to 5.0% by weight of zeolite, and (d) a carrier fluid; and allowing the composition to set in the wellbore.
