Abstract
Methods are disclosed for improved sand control, fines control, load recovery and well productivity, where the compositions comprise reaction products of an amine and a phosphate-containing compound.
Claims30
A method for modifying formation properties comprising the step of:
- treating a formation with a treating composition comprising a reaction product of an amine and a phosphate-containing compound,
- where the reaction product changes a contact angle of formation surfaces, formation particulates, formation fines and/or fracturing proppants towards a neutral wettability value resulting in increased gas production and improved load recovery after fracturing.
A method for controlling sand or fines migration comprising the step of:
- pumping a fluid into a formation at a rate and a pressure sufficient to control sand and fine production or migration into the production fluids, where the fluid includes a composition comprising a reaction product of an amine and a phosphate-containing compound and where the composition increases an aggregation potential or propensity, alters a zeta potential of formation surfaces and/or fines, changes a contact angle of formation surfaces, formation particulates, formation fines and/or fracturing proppants towards a neutral wettability value resulting in increased gas production and improved load recovery after fracturing.
