Sažetak
Effect of polymer swelling that was considered to be a problem, gives today a possibility, to complete wells that are a problem one for conventional packer setting and sealing. Polymers (rubbers) can swell in hydrocarbons or water based fluids as well. Several ways of application have been accepted. Mainly they are connected with open hole and sand screen completions in unconsolidated formations. The ability of changing the volume to more than several hundred percent, can help to avoid packer failure. When defining swelling packer elements it is important to determine their mechanical properties, swelling speed in various fluids, and stability (ageing tests). To implement home made products it was necessary to provide laboratory testing equipment for such purpose. The developed apparatus enables use of different fluids, temperature change up to known reservoir temperature, and pressure differential that element can withstand.
