Abstract
Methods of treating a subterranean formation with treatment fluids containing novel fluid loss control additives comprising alkylpolyglucoside derivatives for treatment fluids are disclosed. In certain embodiments, the methods comprise providing a treatment fluid comprising an emulsion comprising an oleaginous phase and a non-oleaginous phase, a fluid loss control additive comprising an alkylpolyglucoside derivative; introducing the treatment fluid into a wellbore. Fluid loss control additives, drilling fluids, and systems suitable for use therewith are also provided.
Claims19
A method comprising:
- providing a treatment fluid comprising
- an emulsion comprising an oleaginous phase and a non-oleaginous phase, and
- a fluid loss control additive comprising an alkylpolyglucoside derivative, wherein the alkylpolyglucoside derivative comprises a surfactant having two amphiphilic molecules chemically linked to a spacer compound;
- and
- forming one or more micelles within the treatment fluid by adsorbing the fluid loss control additive thereby reducing a fluid loss amount of the treatment fluid;
- and
- introducing the treatment fluid into a wellbore, wherein at least a portion of the wellbore has a temperature of 250° F. or greater.
A method of drilling a wellbore comprising:
- providing a drilling fluid comprising
- an emulsion comprising an external oleaginous phase and an internal non-oleaginous phase, and
- a fluid loss control additive comprising an alkylpolyglucoside derivative, wherein the alkylpolyglucoside derivative comprises a surfactant having two amphiphilic molecules chemically linked to a spacer compound;
- forming one or more micelles within the treatment fluid by adsorbing the fluid loss control additive thereby reducing a fluid loss amount of the treatment fluid;
- pumping the drilling fluid through a drill string and a drill bit disposed in at least a portion of the wellbore;
- and
- using the drilling fluid to drill at least a portion of the wellbore, wherein at least a portion of the wellbore has a temperature of 250° F. or greater.
