* * * * * * * * * * * * * * How do the packers swell? When the packers are exposed to drilling fluids, produced oil or water, or injected fluids, the elastomer begins to swell. The fluids are adsorbed into the elastomer resulting in a volume increase. With the oil swell compound the elastomer adsorbs the oil. With the water swell compound the Super Absorbent Polymer reacts with the water and swells. There are three primary controlling factors in the rate of swell and the maximum volume expansion; Temperature, expansion fluid composition, and the elastomer compound. * How do the packers swell?
