Abstract
A method is described for using an electro-rheological fluid as a drilling and completion fluid or as a well service or fracturing fluid. By adjusting the viscosity of the fluid through application of an electrical potential to the fluid, the fluid has enhanced flexibility and multiplicity of purpose over prior art fluids.
