Abstract
An accumulator insertable into a well fishing string for delivering upward forces to stuck objects in a well having a cased portion. The accumulator has a housing with a top and a bottom, the top and bottom being attachable to a fishing string. A slippage member is positioned on the housing for engaging the cased portion of the well so that when so engaged, the accumulator is supportively connected to the cased portion against downward movement but the accumulator can move upwardly in the well. An activator connected to the slippage member is provided for engaging the slippage member against the wellbore.
