    摘要: Well surface equipment is provided to seal around the outer surface of portions of tool sections as the tool sections are assembled or disconnected in a portion of the well surface equipment. The portion of the well surface equipment is isolated from wellhead pressure to enhance well operator control during assembly or disassembly of a tool string. Also, if a fluid path is opened up due to activation of the tool string (such as initiation of a detonating cord that is placed in the fluid path), a barrier mechanism is actuated to block fluid communication through this fluid path so that a portion of the well surface equipment can remain isolated from wellhead pressure to enable convenient retrieval and disconnection of tool sections.

    摘要: An assembly that is usable with a well includes a base pipe, a screen and at least one perforating charge. The base pipe includes at least one radial port to communicate well fluid, and the base pipe has an outer surface. The screen is mounted to the base pipe and is adapted to at least partially surround the base pipe. The radial port(s) of the base pipe are covered by the screen. The perforating charge(s) are mounted to the outer surface of the base pipe.

    摘要: An integrated sandface completion tool that can be positioned within a wellbore in a single trip and a method of providing a sandface completion in a wellbore. An embodiment of the integrated sandface completion tool includes a casing section having a casing wall, at least one explosive charge connected to the casing wall, and a screen assembly connected within the casing section forming a screen-casing annulus, the screen assembly having openings formed along a portion thereof and a port in selective communication with the screen-casing annulus. The method includes the steps of positioning the integrated completion tool in the wellbore, detonating the explosive charge and packing the screen-casing annulus with a material.
