    摘要： A water-resistant calcium sulphate based body comprises a matrix of crystalline calcium sulphate anhydrite, crystals of the matrix being connected to one another by water-resistant phosphate bonding zones, optionally also containing aluminium. The body can be produced by impregnating a porous calcium sulphate with a source of phosphate ions (optionally containing aluminium), and then calcining. Alternatively, a paste comprising calcium sulphate and a source of phosphate ions (optionally containing aluminium) is heated or compressed to form a ‘green body’ and then calcined to produce the body.

    摘要： A shaped charge includes: a charge case; an explosive disposed inside the charge case; and a liner for retaining the explosive in the charge case, wherein the liner is fabricated from a material soluble with a selected dissolving fluid (e.g., an acid, an acid matrix, an injection fluid, a completion fluid, and/or a wellbore fluid). A method for perforating in a well includes the steps of: disposing a perforating gun in the well, wherein the perforating gun comprises a shaped charge having a charge case, an explosive disposed inside the charge case, and a liner for retaining the explosive in the charge case, wherein the liner is fabricated from a material soluble with a selected dissolving fluid; detonating the shaped charge to form a perforation tunnel in a formation zone; and exposing the material comprising the liner to the selected dissolving fluid.

    摘要： A system for controlling a dynamic pressure transient in a well during operations to provide fluid communication between the wellbore and adjacent formation. A method includes determining the characteristics of an adjacent formation, selecting a perforating tool for increasing fluid communication, determining a dynamic pressure transient to enhance the quality of the fluid communication and prevent damage, selecting a wellbore fluid to achieve the desired pressure transient, and performing the fluid communication process based on the selected parameters.

    摘要： A method and apparatus for improving reservoir communication includes, in one arrangement, use of one or more chambers to create an underbalance condition and/or a fluid surge in the wellbore. In another arrangement, a tool string comprises a packer, a circulating valve, and an atmospheric chamber, in which the circulating valve, when open, is adapted to vent a lower wellbore region below the packer when the packer is set, and the atmospheric chamber is capable of being operated to create an underbalance condition below the packer. In yet another arrangement, an apparatus comprises a subsea wellhead equipment including a blow-out preventer, choke line filled with a low density fluid, and a kill line filled with a heavy fluid. The choke line is adapted to be opened to create an underbalance condition in the wellbore. In yet another arrangement, a method of creating an underbalance condition comprises controlling wellbore pressure at least in a perforating interval to achieve a target level, configuring a perforating gun to achieve a target detonation pressure in the perforating gun upon detonation, and creating an underbalance condition in the perforating interval of the wellbore when the perforating gun is shot. In yet another arrangement, a tool string for use in a wellbore extending from a well surface comprises a closure member adapted to be positioned below the well surface, and a chamber defined at least in part by the closure member. The tool string further comprises at least a port selectively openable to enable communication between the chamber and a wellbore region. The port when open creates a fluid surging to the chamber to provide a low pressure condition in the wellbore region. A tool in the tool string is adapted to perform an operation in the low pressure condition.
