Hydrostatic fields, also called hydrostatic force-fields, were a type of energy membranes developed by the Gungans of Naboo. They were created with plasma from Naboo's porous crust and bubble wort extract. With those membranes, the Gungans created habitation bubbles that not only kept water out and contained breathable atmospheres, but also allowed individuals to pass through at special portal zones.
