摘要： A cavitation device is used to heat and facilitation the separation of mixtures and emulsions of oil and water. Waste heat from the power source for the cavitation device may be utilized to elevate the temperature of incoming mixtures or emulsions. The heated mixture of emulsion is sent to a separation vessel where vapor may be removed and/or recovered, and where oil is removed as it separates into an identifiable layer. The separation vessel may be a flash tank.

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： Formation fluid flows in earth formations (37) opposite a perforated (40) wellbore (15) zone are measured and monitored by injecting radioactive tracers (50) into the perforations (40), blocking the perforations to retain the tracers (50) in the formation (37), monitoring the apparent decay rates (58) of the injected tracers (50), and then determining the rate at which the tracers are being carrier away by fluid movements in the formation (37). From this the flow rate (60) of the fluids in the earth formations (37) adjacent the borehole interval is inferred.

摘要： A method of radioactive well logging for use in well operations wherein hydraulic fracturing material, including radioactive isotopes, is injected from a steel-cased well bore 31 into surrounding earth formations 33. Low energy gamma ray emitting radioisotopes are selected for tagging the liquids phase of the fracturing material and high energy gamma ray emitting radioisotopes are selected for tagging the solids phase. The relative amount of low energy radioisotope material inside the well bore 31 relative to the amount outside the casing 35 is determined to minimize the interfering effects of borehole tracers in determining concentrations of the high energy tracers in the formations. The procedure includes detecting the intensity of gamma radiation from the tracers in the borehole and surrounding formations by a detector 38 in the borehole in proximity to the injection zones and obtaining data representative of the radiation intensity. The intensity data is then separated into an observed energy spectrum from which is obtained observed energy spectrum count rates of gamma radiation in an energy region associated with gamma radiation emitted by the low energy tracer material in at least two relatively low energy ranges, a first P of which is highly sensitive to photoelectric attenuation by iron in the well casing and a second M of which is a higher energy range primarily sensitive to Compton scattered gamma rays and much less sensitive to photoelectric absorption by iron.These count rates are then combined to obtain an observed photoelectric ratio, R.sub.p =(M/P), of the low energy tracer. Count rates of radiation are then obtained in all the energy ranges associated with gamma radiation emitted by the low energy tracer to obtain the total elemental concentration of the low energy tracer in the borehole and the formations. The amount of the low energy tracer in the borehole Tr(Bor) relative to the amount of said low energy tracer outside the casing is determined by a relation involving the observed photoelectric ratio Ph Tr(Obs) of low energy tracer, the total observed concentration of the low energy tracer Tr(Tot), and the low energy photoelectric ratios, Ph Tr(Bor) and Ph Tr(For), calibrated for the tracer in the borehole and in the formation, respectively.

摘要： Uranium ore zones are quantitatively evaluated using the relative photoelectric absorption of naturally occurring gamma rays in two energy bands. One band experiences significant photoelectric absorption from uranium; the other does not. The ratio of the resultant measurements provides a quantitative indication of the uranium concentration.

摘要： According to the method of the present invention a well cement having a high thermal neutron capture cross section is used when cementing the well casing in place. This, possibly together with the use of other high thermal neutron capture cross section materials in the borehole, such a highly saline borehole fluid and/or high thermal neutron capture cross section material sleeves on the well logging sonde, increases the effective depth of investigation of thermal neutron lifetime well logging instrumentation.

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.
