Abstract
A completions insertion and retrieval under pressure (CIRP) apparatus utilizes a snaplock connector to assemble uphole a tool string of any desired length prior to lowering the tool string into a wellbore for performing wellbore operations in the wellbore. The tool string could comprise a perforating gun string including a plurality of perforating guns interleaved with a corresponding plurality of snaplock connectors. The CIRP apparatus includes a winch housing connected to a lubricator, the lubricator being connected to a valve, the valve being connected to a connection apparatus, such as a deployment BOP or a snaplock operator, the connection apparatus being connected to a work string which extends into the wellbore. When the valve is opened and the lubricator is pressurized, a second wellbore tool, which includes a third section of a snaplock connector, is disposed in the lubricator and a first wellbore tool, which includes a first and second section of a snaplock connector, is being held by the connection apparatus. The second wellbore tool is lowered by the winch through the lubricator into contact with the first wellbore tool, and the third section is connected to the second section of the snaplock connector. The connection apparatus releases its hold on the first wellbore apparatus, the winch lowers the second wellbore apparatus into the connection apparatus, and the connection apparatus holds the second wellbore apparatus until a third wellbore apparatus is connected to the second wellbore apparatus thereby creating a tool string. As a result, the tool string of any desired length can be build uphole before lowering the the tool string downhole for performing wellbore operations during one trip into the wellbore.
