Title: Coiled tubing apparatus
Inventor: BROWNE PAUL L
IPC: E21B17/20
Filed: 1996-05-31
Abstract: The  apparatus  and method for  injecting coiled tubing downhole includes a connector member disposed on the end of the coiled tubing and supporting a downhole tool. A packer member is releasably connected to the connector member. The packer member includes a pack-off element and slips for releasably engaging the outer pipe string through which the coiled tubing is being injected. Seals are provided on the packer member for engaging the outer circumferential surface of the coiled tubing.          A fluid passageway extends through the connector member for communicating the packer member with the coiled tubing.  Fluid pressure is applied through the flow bore of the coiled tubing.          The fluid pressure is applied through the fluid passageway to actuate an actuator member in the packer member to set the pack-off element and slips. Thus, upon actuating the packer member, the annulus formed by the coiled tubing and outer pipe string is closed.   Fluid is then applied from the surface into the annulus to support and stiffen the coiled tubing as the injector applies additional force to further inject the coiled tubing downhole.  Upon the setting of the packer member, the packer member is also released from the connector member so that the connector member and downhole tool disposed on the end of the coiled tubing may be further injected downhole.  The connector member includes a dual check valve in the fluid passageway which allows fluid passage to actuate the packer member and closes the fluid passage after the connector member is disconnected from the packer member.   The connector member may also include a valve member which allows circulation down the flow bore of the coiled tubing.   The packer member includes a valve for the passage of well fluids between the packer member and coiled tubing.

Title: Remote smart filtering communication management system
Inventor: LIN TA-SHENG
IPC: H04L12/56
Filed: 1995-10-12
Abstract: Network traffic from a central device across a communication link to a remote device is controlled based upon central traffic management resources in the central device. The central traffic management resources are coupled to a communication link and monitor data packets received across the communication link to learn characteristics of the remote network. Based on the learned characteristics, traffic management messages are generated in the central traffic management resources. These messages are forwarded to an interface device on the remote network, where traffic on the communication link is controlled in response to the traffic management messages. Thus, the remote interface is configured automatically by central traffic management resources running in the central device without human intervention at the remote network. The traffic management messages manage traffic across a communication link of two packets to be forwarded from the remote interface across the communication link. Second, traffic management messages identify types of packets to be composed by the remote interface for communication to users of the remote network. Thus, packages originating on the remote network are filtered so that only necessary packets are forwarded to the central site. Similarly, packets which normally originate from the central site are "spoofed" at the remote site in response to management messages generated at the central site. The central traffic management resources execute a transport protocol for the traffic management messages which are independent of a network address for the remote interface.
