Kinetics of swellable packers under downhole conditions

Swellable packers have been widely employed in various oil-field applications. Examples include zonal-isolation, water shut-off, and multi-stage fracturing. Key factors required for these applications are how fast the packer can seal the borehole as well as how fast a certain amount of contact pressure can build up. These factors, which are generally measured from full-scale packer tests, can be estimated through numerical simulations together with lab-scale experiments. In this work, we have developed a three-dimensional continuum level model and simulation capability to study the behavior of swellable packers affected by various downhole conditions. Such conditions include the borehole type, i.e., permeable or non-permeable borehole, and downhole uncertainties, i.e., variations of borehole size and borehole temperature, which are studied systematically through numerical simulations.
