Wireline set baffle and method of setting thereof

A apparatus for use in a well casing, said apparatus comprising:

• a baffle;
• a running tool engaged with said baffle and adapted for positioning said baffle at a predetermined location in said well casing;
• a lock ring disposed adjacent to said baffle and adapted for engaging said casing at said predetermined location when said lock ring is in a casing engaging position;
• and
• a lock ring retainer for initially retaining said lock ring in a retracted position.

A apparatus for use in a well casing, said apparatus comprising:

• a baffle;
• a setting tool engaged with said baffle and adapted for positioning said baffle at a predetermined location in said well casing;
• a lock ring disposed adjacent to said baffle and adapted for engaging said casing at said predetermined location when said lock ring is in a casing engaging position;
• and
• shearing means for initially retaining said lock ring in a retracted position and adapted for shearing in response to actuation of said setting tool such that said lock ring is freed to move to said engaging position.

An apparatus for use in a well casing, said apparatus comprising:

• a baffle;
• a setting tool engaged with said baffle and adapted for releasing said baffle at a predetermined location in said well casing;
• engaging means for engaging the casing at the predetermined location, said engaging means being characterized by collet fingers extending from said baffle for engaging a recess defined between adjacent casing sections forming a portion of said well casing;
• and
• retaining means for retaining said collet fingers in a retracted position and releasing said collet fingers to a casing joint engaging position when the apparatus is in said predetermined location in said well casing, said retaining means comprising:
• a cover engaging and holding said collet fingers in said retracted position;
• and
• releasing means for disengaging said cover from said collet fingers so that said collet fingers are free to engage said recess.

An apparatus for use in a well casing, said apparatus comprising:

• a baffle comprising a plurality of outwardly biased collet fingers extending therefrom, said collet fingers being adapted for engaging the casing at a predetermined location when said collet fingers are in a casing engaging position;
• and
• a setting tool engaged with said baffle and adapted for positioning said baffle at said predetermined location, said setting tool comprising retaining means for retaining said collet fingers in said retracted position and releasing said collet fingers to said engaging position, said retaining means comprising:
• a cover engaging and holding said collet fingers in said retracted position;
• and
• releasing means for disengaging said cover from said collet fingers.
