Abstract
A method for treating solid materials is disclosed, where the treating compositions coats surfaces or portions of surfaces of the solid materials changing an aggregation or agglomeration propensity of the materials. Treated solid materials are also disclosed. The methods and treated materials are ideally suited for oil field applications.
Claims59
A method for changing an aggregation potential or propensity of a particulate solid material comprising the step of:
- contacting the particulate solid material with a composition including an amine and a phosphate ester under conditions sufficient for the amine and phosphate ester to react forming a partial or complete coating on surfaces of particulate solid material.

A composition comprising a particulate material including a surface having a partial or complete coating deposited thereon, where the coating comprises a reaction product of a phosphate ester and an amine and where the coated particles having improved self-aggregating properties.
A substrate comprising surfaces partially or completed coated with a reaction product of an amine and a phosphate ester, where the coating is deformable and where the substrate is ideally suited for filtering fines and/or other particulate materials form a fluid, especially fluids used in oil/gas well drilling, completion, production, fracturing, propping, other production enhancing processes or other related applications.
A proppant comprising a particulate solid material surfaces partially or completed coated with a reaction product of an amine and a phosphate ester, where the coating is deformable and is designed to be forced into cavities of a fractured formation and prop the cavities open preventing them from collapsing.
