This is further enhanced by the presence of vertical to sub-vertical natural fractures in the formation which require a sealing solution to isolate producing zones. Oil swellable packers were commonly used to provide the isolation required, however, this required oil based fluids to be circulated in the wellbore to activate the packer. The Challenge Due to fractures in the formation, it was essential to isolate multiple frac stages, to preve
