    摘要： Apparatus, in the form of a eutectic alloy plug (1) and a deployment heater (10) are provided. The plug (1) and the deployment heated (10) are provided with means (5, 13) for releasably retaining the deployment heater (10) within a cavity (4) in the plug (1). The nature of the retaining means is such that once the plug (1) is secured in a well the heater (10) can be recovered without the plug (1). An extraction heater (20), which is also receivable within the cavity (4) of the plug (1), is provided to re-melt the eutectic alloy and thus enable the extraction of the plug from a well. Various method of plugging abandoned wells are made possible by the control that the provided apparatus gives.

    摘要： A downhole actuator apparatus that selectively maintains a pressure differential between two pressure regions in a well. The apparatus includes a body defining first and second chambers. A piston is slidably disposed in the body and is selectively moveable between first and second positions. A barrier is disposed in the body to selectively separate the first and second chambers. A fluid is disposed in the first chamber between the barrier and the piston. A control system that is at least partially disposed within the body is operable to generate an output signal responsive to receipt of a predetermined input signal. The output signal is operable to create a failure of the barrier such that at least a portion of the fluid flows from the first chamber to the second chamber and the piston moves from the first position to the second position.
