    摘要: Novel carbon-plus-nitrogen corrosion-resistant ferrous and austenitic alloys, apparatus incorporating an inventive alloy, and methods of making and using the apparatus are described. The corrosion-resistant ferrous and austenitic alloys comprise no greater than about 4 wt. % nickel, are characterized by a strength greater than about 700 MPa (100 ksi), and, when being essentially free of molybdenum (

    摘要: Downhole devices including degradable materials and methods of using such devices to control downhole operations are disclosed. A method for controlling a downhole operation includes providing a device that includes a degradable material downhole; and degrading the degradable material to activate the device. Activation of the device may result in a displacement or flow (actuators) that may be used to control or monitor (sensor) a downhole oilfield operation. A downhole device for use in a well penetrating a formation includes, in part or in whole, a degradable material.
