Abstract: Fluid loss to the permeable fracture face
reduces the overall efficiency of a fracturing fluid. A
thorough understanding of the filtration characteristics of
fluids used for hydraulic fracturing is essential for
realistic design and successful execution of hydraulic
fracturing treatment. The objective of the current study is
to relate the filtration characteristics and therefore, the
time dependence of the fluid loss to various rock and fluid
properties, and treatment parameters. This paper presents
dimensionless correlation for determining the cumulative
volume of filtrate invasion into the rock matrix during
dynamic filtration of a fracturing fluid. The correlation is
developed based on dimensional analysis. The dimensionless
groups considered include the rock and fluid properties such
as permeability, porosity, viscosity, power law exponent,
and consistency index. These groups also include flow
parameters such as fluid velocity and shear rate.
Predictions from the correlation developed in this work are
compared with the experimental fluid loss measurements.
