Abstract: A method for remote communication using the interpretation of thermoluminescence or photoluminescence signals uses a property of photoluminescence or of thermoluminescence when it is caused by entangled trapped electrons. In this case, stimulation of deexcitation of trapped electrons by heat or radiation occurs when the deexcitation thermal energy is approximately equal to the trap-emptying energy. Stimulation by a temperature rise of a “master” sample induces luminescence of a remote “slave” “entangled” sample, which is reproduced on lowering the temperature of the “master” sample whatever the distance and the media separating the “master” sample and the “slave” sample. This teaching and its generalization to other forms of stimulation is used by the method of interpreting the quantum reception measurements so as to determine, using a correlation method, the transmission of information or commands.

Abstract: The invention relates to products, methods and devices for remote communication or control using chromogenic materials. Several samples including at least one kind of chromogenic materials are simultaneously irradiated or radiated together by an appropriate entangled radiation, e.g, gamma, X, ultraviolet or visible radiation, provided by a cascade from an atomic source, or by the target of a linear particle accelerator or by a non-linear crystal. When the samples are separated, one of them, qualified as the master, is stimulated by a traditional method that uses infrared or white radiation or by heating, and a signal is measured that represents the partially correlated excess variation of opacity or coloration of the other sample(s), qualified as slave(s). There is no known method of interference between the master and the slaves. The slave(s) are the only ones capable of instantaneously receiving the signal from the master through all media and from any distance.

Abstract: The method for generating entangled beams of electrons, gamma-ray, X-ray, ultraviolet, visible or infrared photons comprises the following elements: an entangled photon beam generator using a BBO crystal, two branches each containing a photon-to-electron converter (photocathode), an electron amplifier (photomultiplier), an electron accelerator and a target that converts the kinetic energy of the electrons into entangled gamma-ray, X-ray, ultraviolet, visible or infrared photons. The beams obtained in each branch contain groups of gamma-ray, X-ray, ultraviolet, visible or infrared photons that are mutually entangled and entangled with the corresponding groups of the other branch. The entangled electrons may also be used as such before interaction with the target. Variants of the method are presented. One application of the method is the preparation of entangled thermoluminescent products by irradiation by means of entangled gamma-ray beams.

Abstract: The invention relates to a method and device which are intended for remote control and communication using nuclear isomers. Several samples of nuclides that can have a metastable state are irradiated together and simultaneously with cascade gamma-rays emitted from a radioactive source or a particle accelerator. According to quantum mechanics, the gamma-rays produced are entangled, and said entanglement is transferred to the nuclear isomers. When the samples are separated and one of said samples, namely the master, is stimulated using a standard gamma- or X-ray irradiation method, the other samples, namely the slaves, are also deexcited. There is no known method for interference between the masters and slaves. Only the slave(s) can receive the signal instantly from the master through any medium and over any distance. The method and device are particularly suitable for communication and control applications.

Abstract: The invention relates to a method and device for modifying the probability of deexcitation in relation to isomer nuclides, consisting in exciting samples containing nuclides having a metastable state with a half-life varying between one microsecond and 50 years. The excitation is achieved by irradiation with entangled gamma rays produced either by a radioactive isotope, which emits a gamma-ray cascade, or by collisions between accelerated particles and a target, caused by the Bremsstrahlung effect. According to Quantum Mechanics, the gamma-rays produced are entangled, and said entanglement is transferred to the nuclei of the isomer nuclides. As a result, each isomer of the radioactive product obtained has a half-life, which can vary over time and which is initially lower than the theoretical half-life thereof.

Abstract: The described method and device serve to remotely communicate or control by using photoluminescent or thermoluminescent molecules. A number of samples containing the photoluminescent or thermoluminescent molecules are irradiated simultaneously and together by gamma, X, ultraviolet or visible rays emitted in a cascading manner from an atomic source or from the target of a linear particle accelerator or of a nonlinear crystal. When the samples are separated, one of them is stimulated, i.e. the master, by a conventional method of infrared or white illumination or by heating, and the partially correlated luminescence of the other(s), i.e. the slaves, is measured. No method exists for interfering between the master and slaves. The slave(s) is/are the only one(s) that can instantaneously receive the signal of the master across all media and at all distances. The method and devices are provided, in particular, for use in communications or control applications.

Abstract: Test apparatus, and method for accurately and quickly measuring formation pressure, and permeability in oil and gas producing formations; especially low or high permeability formations. The test apparatus can be transported on a drill string, or cable. Preferably, it is employed as a component of a wireline test apparatus. The test apparatus includes, as part and parcel of the combination, an extended drawdown subassembly, or formation pressure test unit, directly associated with the tool flowline. By applying a very slow rate of pressure decrease in the tool flowline, the formation pressure and permeability can be quickly determined, generally during the first minute of testing. In high permeability and soft formations, the formation pressure is determined even if the seal is lost during the flowing period. In low permeability formations, corrections can be made for the supercharging effect using the data collected.

Abstract: A method for accurately determining the formation pressure of earth formans. Formation measurements are made with by use of a novel downhole tool which allows drilling mud to enter the tool in such a way that decompression of drilling mud is controlled so that the pressure in the borehole is allowed to fall only slightly below the formation pressure. The drawdown of mud into the tool is then stopped and the pressure is allowed to stabilize at the formation pressure. The measurement is completed in a matter of a few minutes as opposed to hours, or even days, as required by more conventional techniques.

A pressure versus time curve is generated throughout the test from which the wettability of the formation is determined by comparing how much the injection pressure varies from the static pressure to how much the extraction pressure varies from the static pressure. A wettability index can also be determined from the areas under the curve.

Abstract: A method to determine stress, pore pressure, or other properties of a geological formation by measuring acoustic characteristics of the formation. The acoustic characteristics, which may be one or more of the following group of characteristics-compressional acoustic velocity, shear acoustic velocity, compressional acoustic attenuation, and shear acoustic attenuation-depend on the net stress of the formation. The net stress in turn, depends on the pore pressure. Measurements of one or more acoustic characteristics at several depths allows determination of the net stress, which in turn allows determination of the pore pressure and other properties of the formation.

The tool features a jet charge perforator for detonation to perforate through the wall and positively establish fluidic communication with the non damaged portion of the subsurface formation to be tested. It also includes, in the combination, a mechanism for affixing and stabilizing the tool in the wellbore at the wall of the subsurface formation to be tested, inclusive of a packer assembly for isolating from wellbore fluids the opening between the subsurface formation, created by the jet perforator, and tool test components. On blasting into the wall of the subsurface formation, the pressure in the flowline is maintained at formation pressure, avoiding formation damage.

Abstract: Acoustic signals are transmitted in a direction substantially perpendicular to the borehole axis, from different levels of at least three determined generatrices of the borehole wall. Reflected acoustic signals are received from the same direction at different levels of these generatrices. A train of signals is derived from each reflected acoustic signal and at least a group of significant elements of this signal train is selected. The groups of significant elements of the signals obtained for the different generatrices are correlated. The interval between signal trains corresponding to the maximum correlation corresponds to one and the same geological formation and is representative of the dip angle of this formation.
