Abstract
Composition and methods using the compositions are disclosed, where the compositions include heterocyclic aromatic amines, substituted heterocyclic aromatic amines, poly vinyl heterocyclic aromatic amines, co-polymers of vinyl heterocyclic aromatic amine and non amine polymerizable monomers (ethylenically unsaturated mononers and diene monomers), or mixtures or combinations thereof in the absence of phosphate esters, optionally ethoxylated alcohols, and optionally, which form alter self-aggregating properties and/or aggregation propensities of the particles, surfaces, and/or materials.
Claims23
A method comprising the step of:
- contacting particles, surfaces and/or materials with a coating composition including from about 50 wt. % to about 80 wt. % of heterocyclic aromatic amines, substituted heterocyclic aromatic amines, or mixtures or combinations thereof and from about 10 wt. % to about 30 wt. % of a carrier in the absence of phosphate esters and phosphate ester-amine reaction products, where the coating composition forms a complete or partial coating on the particles, surfaces and/or materials altering self-aggregating properties and/or aggregation propensities of the particles, surfaces, and/or materials and where the coatings deforms under pressure.
A method for controlling sand or fines migration comprising the step of:
- pumping a fluid into a formation at a rate and a pressure into a formation to control sand and fine production or migration into the production fluids, where the fluid includes an aggregating composition comprising from about 50 wt. % to about 80 wt. % of one aryl amine or a plurality of aryl amines, one substituted aryl amine or a plurality of substituted aryl amines, and/or mixtures or combinations thereof and from about 10 wt. % to about 30 wt. % of a carrier in the absence of phosphate esters and phosphate ester-amine reaction products and where the composition forms a deformable partial or complete coating on formation surfaces and/or fines increases an aggregation potential or propensity and/or alters a zeta potential of the formation surfaces and/or fines.
A method for controlling sand or fines migration comprising the step of:
- depositing a coated particulate solid material treated with a treating composition comprising from about 50 wt. % to about 80 wt. % of one aryl amine or a plurality of aryl amines, one substituted aryl amine or a plurality of substituted aryl amines, and/or mixtures or combinations thereof and from about 10 wt. % to about 30 wt. % of a carrier in the absence of phosphate esters and phosphate ester-amine reaction products under conditions sufficient for the treating composition to form a partial or complete deformable coating on surfaces of particulate solid material adjacent screen-type sand and fines control devices so that the sand and/or fines are attracted to the coated particles and do not encounter or foul the screen of the screen-type device.
A composition comprising a particulate material including a surface having a partial or complete deformable coating deposited thereon, where the coating comprises from about 50 wt. % to about 80 wt. % of one aryl amine or a plurality of aryl amines, one substituted aryl amine or a plurality of substituted aryl amines, and/or mixtures or combinations thereof and from about 10 wt. % to about 30 wt. % of a carrier in the absence of phosphate esters and phosphate ester-amine reaction products and where the coated particulate material has improved self-aggregating properties.
A substrate comprising surfaces partially or completed coated with a coating composition comprising from about 50 wt. % to about 80 wt. % of one aryl amine or a plurality of aryl amines, one substituted aryl amine or a plurality of substituted aryl amines and from about 10 wt. % to about 30 wt. % of a carrier in the absence of phosphate esters and phosphate ester-amine reaction products, 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.
