ABSTRACT:
A well barrier for separating two liquids in a gas or oil well. The well barrier includes opposing sets of laths which project slantingly away from a centrally positioned fixing device. A set of upper and lower canvas materials may be affixed to each of the sets of laths to provide enhanced sealing effect. Preferably, the laths are also positioned in an overlapping relationship to thereby minimize the overall length of the well barrier while also maintaining the required functionality.
