Abstract: A method that is usable with a well includes changing a connection between a first coiled tubing segment and a second coiled tubing segment while an upper end of the first coiled tubing section is out of the well and a portion of the first coiled tubing segment is deployed in the well. After the connection is changed, the method includes deploying the remainder of the first coiled tubing segment into the well or retrieving the portion of the first coiled tubing segment from the well.

Abstract: A technique facilitates joining of coiled tubing sections. A framework has one or more movable stands with features designed to grip and manipulate an end of a coiled tubing section. The ability to hold and selectively move an end of a coiled tubing section or the ends of both coiled tubing sections enables an operator to easily prepare the coiled tubing ends and to couple the coiled tubing ends with a coiled tubing connector.

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.

Abstract: An apparatus for connecting a first and a second section of tubing is provided. It comprise a body having a bore therethrough, a first end, a stiff section, and an exterior surface adapted for connection to the first and second sections of tubing. A first tapered section may be provided on the first end of the body, and the first end of the body may be adapted to be disposed within the first section of coiled tubing. A second tapered section may be provided on the second end of the body, and the second end of the body may be adapted to be disposed within the second section of coiled tubing. The first and second tapered sections may be provided with outer and inner tapered surfaces. By connecting two coiled tubings using a connector as disclosed herein, the result is cost savings through an improved joint between two coiled tubings that will withstand bending forces applied proximate the joint in a manner believed to be superior to joints formed by previous coiled tubing connectors.

Abstract: A technique that is usable with a well includes providing a sequencing valve to in a first state to communicate a first flow through a first port of the valve and in a second state close fluid communication through the first port. The technique includes communicating a second flow through an orifice of the sequencing valve during the second state of the valve and using a pressure drop across the orifice the bias the sequencing valve to remain in the second state.
