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.
Claims8
A well barrier for the separation of two liquids in a gas or oil well, comprising:
- (1) a fixing device;
- (2) a first set of laths coupled to said fixing device projecting slantingly away from said fixing device in a first direction;
- and
- (3) a second set of laths coupled to said fixing device projecting slantingly away from said fixing device in a second direction;
- wherein said first set of laths and said second set of laths are positioned in an overlapping relationship.
A method of placing a well barrier at a predetermined location within a well, comprising:
- (1) placing a pipe within said well
- (2) guiding said well barrier within said pipe to said predetermined location within said well by forcing said well barrier through said pipe using a plug;
