Dynamic Fluid Loss of Fracturing Fluids

Abstract

ABSTRACT The relationship between rheology and fluid loss and the effects of shear history, temperature, cross-linker and fluid-loss additive on fluid loss of hydroxypropyl guar gels are discussed. Tests were performed under dynamic conditions using an apparatus which incorporates in-line mixing of crosslinked fluids, so that fluids whose fluid-loss properties are measured have rheological characteristics similar to those generated under field mixing conditions.
