ABSTRACT:
A downhole retrieving tool, in which a tubular member has a tubing string connector end and a conical retrieving dish on the tubular member spaced from and opening towards the tubing string connector end. Stabilizers are spaced around the tubular member at the tubing string connector end. A retrievable whipstock comprises a concave, with a recess formed in the concave between upper and lower conical walls. The upper side wall intersects the face of the concave to form an anchor point. A method for retrieving a downhole tool, such as a whipstock, in a well, in which a retrieving tool having a retrieving dish is lowered into a well, inserted into the recess to engage an anchor point, and removed from the well. Fluid may be injected through circumferentially spaced fluid passageways communicating with the bore of the tubular member to remove unwanted material from the recess.
