| The present Invention relates to a device and a method for perforating downhole casings. The method comprises the steps of arranging a device (1) comprising a pipe section (3) on a drill string, running the device (1) into a bore hole to a desired location in the well, dropping a ball (7) down through the drill string down to the device (1), where the ball (7) rests in a ball seat (5), thus blocking fluid communication between the inside and the outside of the device (1), whereby the pressure on the Inside of the d rill string and the device (1) is pumped up to a first pressure level and a first sequence of pressure rises and pressure reliefs is carried through within a first pressure level Interval, whereby a firing system (4), arranged to react to said first sequence of pressure rises and pressure reliefs, triggers a charge or group of charges (2), whereby the charge or group of charges (2) punches one or more holes through a surrounding casing wall, driving the pressure on the inside of the drill string further up to a second level causing a rupture disc (8), arranged in an opening (10) in the pipe wall to the pipe section (3) somewhere above the ball seat (5), to burst and establishing a fluid communication between the inside and outside of the drill string through the opening in the pipe wall of the pipe section (3), and to start a circulation In the well by pumping a fluid down through the drill string and out through the opening which is created when the rupture disc (8) bursts. | ||||||

| The present invention relates to a stimulation method comprising the steps of arranging a fluid-activated gun in a well through a well head and/or a blowout preventer, dividing the well into a first and a second part, the first part being closer to the well head and/or blowout preventer than the second part, pressurising the first part of the well with a hot fluid, the hot fluid having a temperature which is higher than the temperature of the formation at a downhole point of injection, activating the fluid-activated gun, thereby converting energy from the pressurised hot fluid into mechanical waves, directing said mechanical waves into the formation, and injecting the hot fluid into the formation simultaneous to activation of the fluid-activated gun by means of the hot fluid. Furthermore, the present invention relates to a stimulation system for stimulation of oil production in an oil field. | ||||||

| A carrier tube for use in a wellbore perforating gun has inner and outer layers selected from materials of different, comparative physical properties. The inner layer has a higher compressive strength, and the outer layer has a higher yield strength. The inner layer enables the tube to withstand wellbore compressive pressures, which may, depending upon the material selected, include relatively high pressures, while the outer layer contains any fragments of the inner layer that result upon detonation of the gun. It is emphasized that this abstract is provided to comply with the rules requiring an abstract which will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims. | ||||||

Apparatus and methods for controlling and communicating with one or more tools in a downhole tool string including a tractor, an auxiliary tractor tool, a logging tool, a safety sub, a release mechanism, a unit containing sensors for monitoring downhole conditions, a setting tool, and a perforating gun. Control and communication are accomplished by sending signals from the surface to control switches in the control units on the tool, with redundant switches for safety, to state machines in the respective control units, each state machine returning a signal verifying switch status to the surface. The state machine need not return a signal including a unique identifier.
