| A process for increasing the degree of extraction of oil or other volatile liquids in oil reservoirs on land or at sea, by making the formations in said reservoir vibrate as close to the natural frequency of said formations as possible, so that the binding forces between formations and oil are degraded and oil is, thus more easily recovered from the formations. Furthermore, the pressure in said reservoir is maintained by evaporating some oil and water in the reservoir, due to the fact that heating is achieved both as a consequence of said vibrations, and by the aid of electrical high frequency pulses causing the reservoir to perform like an electrode furnace. | ||||||

| Un procédé, destiné à augmenter le degré d'extraction du pétrole ou d'autres liquides volatiles dans des réservoirs de pétrole sur terre ou en mer, consiste à faire vibrer les formations présentes dans lesdits réservoirs à une fréquence aussi proche que possible de leur fréquence naturelle, de telle sorte que les forces de liaison entre les formations et le pétrole soient réduites et que celui-ci soit par conséquent extrait plus facilement desdites formations. En outre, la pression dans lesdits réservoirs est maintenue en évaporant une partie du pétrole et de l'eau contenus dans les réservoirs, puisque l'augmentation de la température est due d'une part à l'effet desdites vibrations et d'autre part à l'aide d'impulsions à haute fréquence électrique qui permettent aux réservoirs d'agir comme un four à électrodes. | ||||||

An apparatus and method for pumping oil or other fluids from the earth is disclosed as susing a submersible pump (101) which is suspended in a hole (1) drilled into the earth by means of a flexible cable (103). Encased in a flexible sheath (147) with the cable are a power cable (143) forthe pump and a flexible hose (141) to carry the oil from the pump to the surface of the earth. Control and signal wires (163) may also be encased in the sheath for connection to transducers mounted on the pump.

| 172 | Oil production intensification device and method | US14505015 | 2014-10-02 | US09896917B2 | 2018-02-20 | Olga Nikolaevna Sizonenko; Alexander Ivanovich Vovchenko; Igor Semenovich Alexandrov |
| The oil production intensification method includes injecting the reagent into the reservoir and treating the bottom zone of the well with high voltage pulse discharges with an electric discharge device continuously traveling from bottom to top in the atmosphere of such reagent. The number of pulses of such high voltage pulse discharges is set subject to the real porosity of the reservoir and the empirical dependence of the number of pulses of high voltage pulse discharges per meter of the reservoir and porosity of rocks pre-estimated with the core material. After the electric discharge device stops traveling up, the treatment with high voltage pulse discharges also stops, and the well is pressurized until the pressure stabilizes in it. Then, the bottom hole area of the well is further treated with high voltage pulses as the electric discharge device travels from top to bottom. Whereby an intensified oil production is realized, from 2 to 20 times more oil may be extracted. | ||||||

| Disclosed are methods, systems, and devices for increasing well and oil field productivity. The method comprises positioning an acoustic device in a well located within the geological formation and performing an acoustic treatment impacting a muddled zone in cycles comprising one or more manipulated waves of ultrasonic pressure on the muddied zone. The cycles comprise a Fourier transformation of a periodic function. The transformation determines a rate at which an acoustic treatment pressure of each cycle rises from zero to a maximum value. This rate is directly proportional to a force of an impact on the formation, and the greater the rate, the greater the impact. The acoustic treatment can further be detected by placing emitters and receivers in surrounding wells and calculating the signal received to determine if wells are hydrodynamically connected, such that a synergistic effect may be achieved through simultaneous treatment at several well locations. | ||||||
| 180 | Adaptive Stimulation System | US14919848 | 2015-10-22 | US20170114620A1 | 2017-04-27 | Dennis W. Gilstad; Barbara C. Gilstad |
| Adaptive stimulation systems combine impulse-generated swept-frequency stimulation vibration with cyclically-varying hydraulic pressure to provide adaptive down-hole stimulation. Swept-frequency stimulation vibration arises from cyclical shifts of the power spectral density (PSD) of each stimulator's vibration (via closed-loop control of rebound cycle time). PSD's are adjusted for resonance excitation, fracturing and/or analysis of geologic materials at varying distances from a wellbore. And closed-loop control incorporates backscatter vibration from stimulated geologic material. Stimulators can be arranged singly or in spatial arrays of multiple stimulators, each stimulator generating vibration in bursts comprising a plurality of vibration frequencies. Timed signals from a programmable controller affect directional propagation of combined vibration wave fronts from a stimulator array. As fracturing proceeds to smaller (e.g., proppant-sized) fragments having higher resonant frequencies, PSD's are up-shifted, increasing relative stimulation vibration power in higher frequencies. Progressive stimulation is thereby optimized, facilitating plain-water (or liquefied propane) fracs with self-generated proppant. | ||||||
