Patent ID: 7249633

Claim:
A release tool to attach wiled tubing to a bottom hole assembly in a well bore, comprising: a fishing neck housing functionally associated with the bottom hole assembly; a release tool mandrel attached to the coiled tubing and adapted to move axially with respect to the fishing neck housing upon the application of an upward force on the coiled tubing; and a reset mechanism, the reset mechanism functionally associating the fishing neck housing and the release tool mandrel such that a predetermined combination of a first upward force may be applied for a corresponding first amount of time to the release tool mandrel without releasing the bottom hole assembly, and such that the after the application of the predetermined combination of the first upward force for the first amount of time, the application of a second upward force wilt release the bottom hole assembly from the coiled tubing, the reset mechanism having a a first chamber, a second chamber, and a biasing means adapted to apply a biasing force, wherein a pressure fluid is adapted to flow from the second chamber to the first chamber after the first predetermined upward force is applied by the coiled tubing, the biasing means adapted to move the release tool mandrel downwardly within the fishing neck housing to reset the release tool when the upward force is reduced below a downward force of the biasing means, wherein the biasing means moves the mandrel downwardly within the fishing neck housing when the upward force is reduced below the force of the biasing means, the downward force from the biasing means forcing pressure fluid from the first chamber to the second chamber, in which rate the pressure fluid flows from the first chamber to the second chamber is controlled by a resetting check valve.
