ABSTRACT:
Gas and oil well swabs, particularly a dynamic seal for maintaining gas-tight contact between the moving swab and the well casing. The seal includes a reinforcing tube and a flexible annulus having an upper throat portion complementally engaging the exterior of the reinforcing tube and a lower bell-shaped skirt portion, engageable with the well casing. The lower bell-shaped skirt portion of the seal defines an expansion chamber for the well gas, which lifts the swab.
