Abstract
Non-toxic, biodegradable base fluids are disclosed for use in making downhole fluids, where the base fluids include blends of paraffins, olefins, naphthenes, esters, and oxygenates, having low viscosities, having a pale-yellow color, having a flashpoint of >80° C. (175° F.) and have a pour point of about 19° F. Methods for making and using fluids include the base fluids of this invention are also disclosed
Claims21
A base fluid composition for use in downhole fluids comprising blends of paraffins, isoparaffins, olefins, naphthenes, esters, and/or oxygenates, where the composition has low viscosity, a pale-yellow color, a flashpoint of >80° C. (175° F.), a pour point of about 19° F., is non-toxic, and biodegradable.
A fluid composition for use in downhole applications comprising:
- a base fluid comprising blends of paraffins, olefins, naphthenes, esters, and oxygenates, having low viscosities, having a pale-yellow color, having a flashpoint of >80° C. (175° F.) and have a pour point of about 19° F.
A method for making a downhold fluid comprising:
- adding an additive package to a base fluid comprising a blend of paraffins, olefins, naphthenes, esters, and/or oxygenates, where the base fluid has a low viscosity, a pale-yellow color, a flashpoint of >80° C. (175° F.), a pour point of about 19° F. is non-toxic, and biodegradable.
