摘要： Systems, methods, and apparatuses involve selecting an aperture geometry to filter solids from fluid from a subterranean zone, the aperture geometry selected based on a distribution of sizes of particles in the fluid from the subterranean zone. A laser can be used to form slots with the selected aperture geometry in a casing installed in a well in the subterranean zone, the aperture geometry having a size selected based on the distribution of sizes of the particles.

摘要： A method of delivering a desired relatively high optical power to a well tool in a subterranean well can include coupling to an optical waveguide an optical source which combines multiple optical frequency ranges, respective centers of the frequency ranges being separated by at least a peak shift frequency in a Raman gain spectrum for a corresponding pump wavelength generated by the optical source, and transmitting the desired optical power to the well tool via the optical waveguide positioned in the well. Another method of delivering optical power to a well tool in a subterranean well can include coupling to an optical waveguide an optical source, the optical source comprising a sufficient number of lasing elements to transmit the optical power, with the optical power being greater than a critical power for stimulated Brillouin scattering in the waveguide.

摘要： A method for wellbore perforation in which a section of the wellbore to be perforated is isolated and purged of wellbore fluid to provide a clear path for laser beam transmittal. A laser beam emitter in the purged wellbore section transmits a laser beam pulse from the laser beam emitter to a target area of a sidewall and formation lithology of the purged wellbore section, thereby altering a mechanical property of a material of the sidewall and formation lithology and producing material debris. A liquid jet pulse of a liquid is transmitted immediately following termination of the laser beam pulse to the target area, thereby removing the material debris from the target area. This cycle is then repeated until the desired perforation depth has been achieved.

摘要： An apparatus, system and method are provided for measuring state properties without requiring an internal or proximate power supply. The apparatus provides a sensing device that is responsive to fluctuations in a state property that are encountered within the test zone. Due to the fluctuations experienced by the sensing device, a sensing signal is generated and transmitted to an optical device, such as an interferometer. The sensing signal's affect on the optical device produces an interference pattern that may be detected remotely and correlated to the fluctuation experienced by the sensing device.

摘要： Systems, apparatuses, and methods for producing fluids from a wellbore wherein fluids may be communicated through an aperture in a wall of the wellbore. A laser can then be used to seal the aperture in the wall of the wellbore. The wall of the wellbore may include a casing, and the laser can be used to seal the aperture in the wall of the wellbore by fusing apertures in the casing shut. Fusing the aperture in the casing can involve heating the casing such that opposite sides of the aperture fuse together or can involve selectively laser sintering fusible powders. The wall of the wellbore can be an open hole and using a laser to seal the aperture can include sealing the aperture in side surfaces of the open hole by glazing the surface of hole extending into a subterranean formation.
