A process for forming a particle carrier system includes supplying a particle carrier, the particle carrier having a surface and modifying the particle carrier surface to include a first ionic functional group. The process also includes chemically binding the first ionic functional group on the particle carrier surface to a first ionic molecule.

Methods and treatments fluids for treating a wellbore. One example method introduces the treatment fluid into the wellbore. The treatment fluid comprises an aqueous fluid, an aminopolycarboxylic acid, a nanoparticle dispersed, and an organic solvent. The treatment fluid has a pH in a range between about 5 to about 9. The method further includes contacting a rock surface in the subterranean formation; wherein at least a portion of the rock surface is coated with a hydrocarbon. The treatment fluid removes a portion of the hydrocarbon from the rock surface and alters the rock surface to be water-wet.

A spherical organic nano boron crosslinker with a PAMAM core and a preparation method thereof, and a gel fracturing fluid. A chemical structure of the spherical organic nano boron crosslinker is shown as follows: ##STR00001##
In the formula, n=0, 1, 2 or 3; and ##STR00002##

The invention is directed to delayed gelation agents comprising a degradable polymeric cage containing therein one or more gelation agents. The cage degrades in situ, e.g, in an oil reservoir, thus releasing the gelation agent(s), which can then crosslink second polymers in situ to form a gel.
