ABSTRACT:
A connection between coiled tubing and a connector includes a plurality of dimples formed by a tubing, each dimple is disposed within a respective pocket formed in a connector to form at least two rows of dimple-pocket connections, wherein the fit of the dimples within the pockets of the rows graduates from tighter to looser along the length of the connection. The connection may further include a seal member positioned between the tubing and the connector positioned between at least two of the rows of dimple-pocket connections formed. A method of connecting coiled tubing to a connector includes the steps of graduating the dimple-pocket connections from tighter to looser along the length of the connection.
