Packer releasing tool and method for releasing a packer assembly from a wellbore

A system for releasing a packer from a wellbore, comprising,

• a packer coupled to a tubing string and having a packer releasing profile with a packer uphole shoulder and a packer downhole shoulder;
• a packer releasing tool, comprising;
• a toplock assembly removably coupled to a downlock assembly;
• a toplock key movably coupled to said toplock assembly and having a toplock key profile engageable against said packer releasing profile;
• a downlock lug movably coupled to said downlock assembly and having a downlock lug profile engageable against said packer releasing profile, said packer releasing tool having an outer diameter less than an inner diameter of said tubing string such that it may pass through said tubing string;
• and
• a downhole power unit couplable to said packer releasing tool.

For releasing a packer from a wellbore, said packer coupled to a tubing string and having a packer releasing profile with a packer uphole shoulder and a packer downhole shoulder, a packer releasing tool, comprising:

• a toplock assembly removably coupled to a downlock assembly, said toplock assembly having a running profile;
• a toplock key movably coupled to said toplock assembly and having a toplock key profile engageable against said packer releasing profile, said toplock key further having an inner profile, said running profile configured to cooperatively engage said inner profile and receive said toplock key therein as said packer releasing tool is run into said wellbore;
• and
• a downlock lug movably coupled to said downlock assembly and having a downlock lug downhole stop shoulder engageable against said downhole shoulder, said downlock lug profile including a running profile configured to cooperatively receive said downlock lug therein as said packer releasing tool is run into said wellbore, said packer releasing tool having an outer diameter less than an inner diameter of said tubing string such that it may pass through said tubing string.

A method for releasing a packer from a wellbore, said packer coupled to a tubing string and having a packer releasing profile with a packer uphole shoulder and a packer downhole shoulder, comprising:

• positioning a packer releasing tool within a packer positioned in a wellbore, said packer releasing tool having a toplock assembly removably coupled to a downlock assembly;
• engaging a toplock key profile of said toplock assembly against said packer releasing profile;
• engaging a downlock lug profile of said downlock assembly against said packer releasing profile;
• and
• releasing said packer from said wellbore.
