摘要： A method for the anodic electrochemical synthesis of ammonia gas. The method comprises providing an electrolyte between an anode and a cathode, providing nitrogen and hydrogen gases to the cathode, oxidizing negatively charged nitrogen-containing species and negatively charged hydrogen-containing species present in the electrolyte at the anode to form adsorbed nitrogen species and adsorbed hydrogen species, respectively, and reacting the adsorbed nitrogen species with the adsorbed hydrogen species to form ammonia. Nitrogen and hydrogen gases may be provided through a porous cathode substrate. The negatively charged nitrogen-containing species in the electrolyte may be produced by reducing nitrogen gas at the cathode and/or by supplying a nitrogen-containing salt, such as lithium nitride, into the molten salt electrolyte. Similarly, the negatively charged hydrogen-containing species in the electrolyte may be produced by reducing hydrogen gas at the cathode and/or by supplying a hydrogen-containing salt, such as lithium hydride, into the molten salt electrolyte.

摘要： Methods and apparatus are provided for continuously powering tools downhole for extended periods of time, such as for the life of the producing well. Batteries may power the downhole tools, but traditionally, the batteries may last up to 2 years, and in some cases, up to 5 years may be reached with an optimized data sampling rate and power management scheme. After that time, operations may be halted temporarily for replacing the batteries. According to embodiments of the present invention, in contrast, rechargeable batteries may be utilized downhole to provide power to operate the tools, and rather than halting operations and retrieving the rechargeable batteries to the surface for recharging, reserve batteries may be used for recharging the rechargeable batteries. In many cases, these well tools may be designed to operate for a long period of time (e.g., around 10-20 years), depending on the life of the producing well.

摘要： A method of monitoring the wear of drill bits for drilling wells in earth formations, several embodiments of an improved drill bit for drilling a well in an earth formation, and methods of manufacture. In one embodiment, the bit is assembled by forming the bit, including a bit body and a plurality of cutting components; introducing a wear detector into the bit; and providing a module to monitor the wear detector and generate an indication of bit wear. The wear detector may be one or more electrical circuits that may experience a change in resistance or conductivity due to wear of the bit. The module may determine wear by detecting an open circuit. The wear detector may be introduced during or after formation of the bit. The bit wear may be displayed for an operator.

摘要： A spindle assembly for supporting a drill bit for repair. The spindle assembly includes a plurality of stepped segments of ever-decreasing diameter above a base, each segment sized to be received in a bore of a service cap inserted in the shank of a bit to be repaired. An end-cap for carrying an electronics module includes an end-cap body comprising a bore of similar diameter to the service cap bore diameter, but having one or more lugs protruding radially thereinto to prevent a spindle segment from entering the end cap bore so that the drill bit cannot be supported on the spindle.
