摘要： A method for purging of, and debris removal from, a hole created with laser energy in which a swirling purge gas stream is provided in a hole containing debris to be removed, imparting a swirl to the debris and lifting the debris from a bottom of the hole. In accordance with one embodiment, the purge gas is swirled in a purge gas nozzle providing purge gas into the hole. In accordance with another embodiment of this invention, the purge gas is swirled directly in the hole.

摘要： A tool comprising a tool body (26) and tool electronics located within the tool body, wherein the tool electronics (916) are operable to sense a tool component characteristic indicative of tool performance such as temperature, acceleration, pressure, rotation, strain or vibration. At least some of the tool electronics are operable, at least for one week, when exposed to temperatures of at least 200 Celsius. The tool electronics may be integrated circuits formed on a silicon carbide substrate (602, 702) or a silicon on sapphire substrate (602, 702). One illustrative embodiment of the tool is a drill bit for employment in a high temperature drill well.

摘要： A method of reducing CO
2 emission from a wellsite diesel engine includes the steps of: providing the wellsite diesel engine operatively coupled to a wellsite apparatus for transmission of power from the wellsite diesel engine to the wellsite apparatus; and injecting at least one component of natural gas into the wellsite diesel engine, thereby combusting the natural gas component in the wellsite diesel engine. A system for supplying power to a wellsite apparatus includes a wellsite diesel engine operatively coupled to the wellsite apparatus for transmission of power to the wellsite apparatus; a diesel fuel supply; a natural gas component fuel supply which supplies at least one component of natural gas; and each of the diesel and natural gas component fuel supplies being connected to the wellsite diesel engine for combustion therein of a mixture of diesel fuel and the natural gas component.
