Application No. 08/758,655
DECISION ON APPEAL
This is a decision on appeal from the examiner’s final
rejection of claims 21-25, 33-37 and 41-48. Claims 27-32, 38-
40 and 50-54, the only other claims remaining in the
application, are allowed. Claims 1-20, 26 and 49 have been
canceled.
Appellants’ invention relates to a one-trip well
completion method of running in a packer and a perforating
gun, setting the packer and firing the perforating gun in a
wellbore. As discussed by appellants in the Background of the
Invention, in prior art methods wireline equipment was used to
run in and set a packer. Following the setting of the packer,
a separate trip was made into the wellbore with tubing to
convey and fire a perforating gun.
In an effort to reduce the number of trips from two to
one appellants have developed a method of conveying both the
packer and the perforating gun with the same tubing. Setting
the packer automatically releases the gun from the packer.
The packer is set and the gun is fired by using pressure,
