摘要： A method for real-time monitoring of fracture extension during a fracturing treatment of a producing subterranean formation. A radioactive tracer injector is coupled to and spaced from a gamma ray detector by a distance approximately equal to a distance from a point of injection during fracturing to a boundary between the desired interval to be fractured and an adjacent formation which it is desired not to fracture. A programmed central processing unit positioned at a surface location receives spectral signals generated by the gamma ray detector during the fracturing treatment and generates a fracture penetration signal and a fracture injection pump control signal that stops a fracture injection pump whenever the fracture extension signal indicates the presence of radioactive tracer material within the producing subterranean formation at the depth location of the gamma ray detector. The programmed central processing unit distinguishes between the presence of radioactive tracer material within the formation versus radioactive tracer material within the borehole itself.

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： A downhole oil and water separator for an oil well includes a water-selective membrane disposed in a production flowpath of the well. The water-selective membrane is operable to selectively pass water from the production flowpath to a disposal zone to increase the concentration of oil in the production flowpath at the surface.

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： Improved vertical resolution from pulse neutron logs is obtained by the disclosed process; a pulse of fast neutrons is emitted from a source and counts are taken at near and far dectors. This is done repetitively so that the interval between neutron bursts is conveniently divided into a number of gates, the preferred form being six contiguous gates. The count rate especially in gates 3-6 is obtained and is processed in a modified form to thereby enhance vertical resolution. While before vertical resolution was dependent in part in spacing of the detectors and source, improved vertical resolution is obtained to thereby locate thin beds which would otherwise be obscured.

摘要： In logging operations in a well borehole where difficulties arise in retrieval of the logging apparatus, drilling through the logging tool is sometimes necessary. This disclosure sets forth a radioactive source material which permits this remedial step. The radioactive source material is either a short half life radioactive isotope or is in fluid form. In fluid form, it is purged out of the sonde by means of a motor controller triggered into operation to operate a piston and cylinder pump arrangement. The outlet from the cylinder is through a flow line and check valve. The purged radioactive source material is then flushed to the bottom of the well borehole and is ideally forced into a selected formation for disposal, thereby safely removing the radioactive materials from the sonde to permit destruction of the sonde.

摘要： Methods are disclosed herein for determining the point of entry of water cut into a cased well borehole. A well logging sonde is moved past a perforated interval in a cased well borehole. The borehole environment is irradiated with 14 MeV neutrons from a neutron source and measurement of movement of oxygen activated borehole fluid past two gamma ray detectors spaced from the neutron source is combined with the speed of movement of the logging sonde to derive a signal representative of the entry location and flow rate of the oxygen activated fluid. At least one borehole fluid sample is taken in the interval between the point of neutron irradiation and the detection of oxygen activation gamma rays to resolve any ambiguity in the total flow rate of borehole fluid in the interval.

摘要： Naturally occurring gamma radiations from earth formations in the vicinity of a well borehole are detected and spectrally separated into six energy regions or bands. Borehole compensation techniques are applied to the gamma ray spectra and the attenuation coefficient .eta. is determined as a result thereof. The attenuation coefficient is used along with predetermined borehole, casing and cement parameters to derive a measure of the density of the earth formations.
