摘要： A system and method of drilling and/or perforating uses a laser beam to remove material, such as to perforate the casing, cement and formation or drill a well bore. The system and method can further or alternately encompass material analysis that can be performed without removing the material from the well bore. The analysis can be performed apart from or in connection with drilling operations and/or perforating the casing, cement and formation. The analysis can be used in a feed back loop to adjust material removal, adjust material analysis, determine the location of future material removal, and for other uses.

摘要： A method for determining the location and height of a fracture in a subterranean formation using a neutron emitting logging tool. The method includes obtaining a pre-fracture data set, fracturing the formation with a slurry that includes a proppant doped with a high thermal neutron capture cross-section material, obtaining a post-fracture data set, comparing the pre-fracture data set and the post-fracture data set to determine the location of the proppant, and correlating the location of the proppant to a depth measurement of the borehole to determine the location and height of the fracture. Using the PNC tool, it is also possible to determine whether the proppant is located in the fracture, in the borehole adjacent to the fracture, or in both. The method may also include a plurality of post-fracture logging procedures used to determine various fracture and production characteristics in the formation.

摘要： Proppant placed in a subterranean fracture zone is detected with a spectral identification method in which capture gamma ray spectra are obtained during a logging run carried out with a logging tool having a neutron emitting source and at least one detector sensitive to thermal neutron capture gamma rays. Capture gamma rays from one or more high thermal neutron cross-section materials in the proppant are distinguished from capture gamma rays produced by thermal neutron capture reactions with other downhole formation and borehole constituents utilizing a spectral processing/deconvolution technique. The capture gammas rays from the high thermal neutron capture cross section material in the proppant are used to identify propped fracture zones either alone or in combination with other proppant identification methods which rely on measuring thermal neutron related count rates and/or thermal neutron capture cross-sections from neutron, compensated neutron, and/or pulsed neutron capture logging tools.

摘要： Cesium solutions are treated in a cavitation device to increase their temperature and facilitate the removal of water from them. The context is normally an oil well fluid or a mining solution. The concentrated solutions can be reused, in the case of oil well fluids, or more easily handled for recovery of the elemental cesium or cesium in the form of a salt. Thermal energy is saved by using the concentrate or the water vapor to heat various streams within the system.

摘要： Methods are provided for identifying the location and height of induced subterranean formation fractures and the presence of any associated frac-pack or gravel pack material in the vicinity of the borehole using pulsed neutron capture (PNC) logging tools. The proppant/sand used in the fracturing and packing processes is tagged with a thermal neutron absorbing material. When proppant is present, increases in detected PNC formation and/or borehole component cross-sections, combined with decreases in measured count rates, are used to determine the location of the formation fractures and the presence and percent fill of pack material in the borehole region. Changes in measured formation cross-sections relative to changes in other PNC parameters provide a relative indication of the proppant in fractures compared to that in the borehole region.

摘要： Membrane tubes or similar membrane devices are arrayed in layers so that liquid placed on their outer surfaces may be evaporated and also drain onto lower membrane devices. The entire array is subjected to moving air to enhance evaporation. The membrane devices function as filters while permeating water from industrial fluids while also providing evaporative surfaces to reduce the volume of used aqueous industrial fluids. The retentate surfaces of the membrane devices may also be on the interiors of the devices, and the permeate contacted with flowing air to evaporate the permeate. Unevaporated permeate is collected in either configuration for use as clean water, and concentrated fluid may be more easily handled, disposed or, and/or its components recycled. A cavitation device may be used to heat the aqueous industrial fluid to enhance permeation and evaporation rates with minimal scaling.

摘要： Oilfield completion, drilling and workover fluids containing iron are treated to remove the iron by passing them through a cavitation device together with an oxidizing agent. The cavitation device intimately mixes the oxidizing agent with the fluid while increasing the temperature of the fluid, thus promoting the oxidation reaction. Ferric hydrate and other solids or colloidal iron are removed in a filter capable of removing particles as small as 0.5 micron. The system may be enhanced by the addition of a bed of activated carbon capable of catalyzing the oxidation reaction.

摘要： A separating system for separating a fluid mixture incorporates a smart surface having reversibly switchable properties. A voltage is selectively applied to the smart surface to attract or repel constituents of a fluid mixture, such as oil and water produced from a hydrocarbon well. The smart surface can be used in a conditioner to increase droplet size prior to entering a conventional separator, or the smart surface and other elements of the invention can be incorporated into an otherwise conventional separator to enhance separation. In a related aspect, a concentration sensor incorporating smart surfaces senses concentration of the fluid mixture's constituents.

摘要： Subterranean formation locations/heights of tagged proppant doped with a high thermal neutron capture cross-section material are determined using data obtained from before and after frac logging passes through a well of a logging tool having near and far neutron dectors. Proppant location inaccuracies arising from changes in lithology between a zone of no interest and a proppant-containing formation zone are made, after any required normalization for a between-log change in borehole fluid, using an observed difference between the near/far detector count rate ratios in the two passes to determine a count rate differential correction to be applied to the before frac detector count rate. The corrected before frac count rate log is then overlaid with the after frac count rate log such that suppression in the after frac count rate log relative to the corrected before frac count rate log indicates the presence of proppant.
