Abstract
An aqueous drag reducer having the components of water, a hydrocarbon soluble rheology modifier and an ultra-high molecular weight polymer. This aqueous drag reducer is also soluble in hydrocarbons.
Claims12
An aqueous drag reducer comprising:
- water;
- an amine oxide rheology modifier that is soluble in hydrocarbons;
- and
- a polymer that is soluble in the hydrocarbons and has a molecular weight greater than one million.
1 more element
A method comprising:
- producing a suspension medium;
- incorporating a polymer having a molecular weight greater than one million to the suspension medium to produce a suspension;
- and
- adding a hydrocarbon soluble amine oxide rheology modifier to the suspension to produce an aqueous drag reducer.
1 more element
A method comprising:
- mixing water and a surfactant to produce a suspension medium;
- incorporating a polymer having a molecular weight greater than five million, to the suspension medium to produce a suspension;
- adding an amine oxide rheology modifier that is soluble in a refined hydrocarbon to the suspension to produce an aqueous drag reducer;
- and
- injecting the aqueous drag reducer into the refined hydrocarbon pipeline.
