| 202 | Method and assembly for recovering oil using elastic vibration energy | US13266491 | 2010-04-16 | US09004165B2 | 2015-04-14 | Anna Vladimirovna Abramova; Vadim Muratovich Bayazitov; Andrei Andreevich Pechkov |
| A method and assembly for recovering oil using elastic vibration energy involves placing a downhole apparatus in a well, which downhole apparatus is connected to aboveground power supply units and contains an ultrasonic transducer that provides for the generation of high frequency elastic vibrations, exciting elastic vibrations of different frequencies and then repeatedly applying the elastic vibrations to the oil formation, wherein both high and low frequency vibrations are applied to the formation. The low frequency vibrations are generated with the aid of an electric pulse device which is connected to an aboveground power supply and includes the following electrically interconnected components: a charger, a unit of energy storage capacitors, a discharge unit with electrodes, and two switching devices. The method and assembly make it possible to recover oil from depths of over 2000 meters and to act effectively on the formation being treated. | ||||||
| 203 | DRILLING CONTROL AND INFORMATION SYSTEM | US14389482 | 2013-04-03 | US20150053483A1 | 2015-02-26 | Robert Eugene Mebane, III |
| A drilling control and information system comprising: a rig site network (102) including a drilling equipment controller (112) and a drilling parameter sensor (116); a downhole sensor (118) communicatively coupled to the rig site network; a data center (104) communicatively coupled to the rig site network; a remote access site (106) communicatively coupled to the data center; and a pressure management application (300) communicatively coupled to the rig site network, wherein the pressure management application receives pressure data from the drilling parameter sensor and the downhole sensor and issues an operating instruction to the drilling equipment controller. | ||||||
| 204 | Tunable hydraulic stimulator | US14248360 | 2014-04-09 | US08939200B1 | 2015-01-27 | Dennis W. Gilstad; Barbara C. Gilstad |
| Selected designs for reciprocating pumps and down-hole well-stimulation equipment reflect disparate applications of identical technical principles (relating to, e.g., the vibration spectrum of an impulse). In certain of these designs, the vibration spectrum is controlled, suppressed and/or damped using tunable components to limit destructive excitation of resonances; in others the vibration spectrum is tuned at its source for maximum resonance excitation. For example, tunable fluid ends control valve-generated vibration to increase fluid-end reliability. By down-shifting the frequency domain of each valve-closing impulse shock, initial excitation of fluid end resonances is minimized. Subsequent damping and/or selective attenuation of vibration likely to excite one or more predetermined (and frequently localized) fluid end resonances represents further optimal use of fluid end vibration-control resources. Vibration generation in stimulators, in contrast, includes techniques for production of desired frequency bands (vibration spectra) and amplitudes (vibration energy) near explosively-formed perforations in a wellbore. | ||||||
| 205 | METHOD AND SYSTEM FOR IMPACT PRESSURE GENERATION | US14366648 | 2012-12-19 | US20150000917A1 | 2015-01-01 | Jim-Viktor Paulsen |
| A method is described for the recovery of hydrocarbon from a reservoir. The method includes arranging a chamber in fluid communication with the reservoir via at least one conduit, and having the chamber comprising first and second wall parts movable relative to each other. An impact pressure is provided in the fluid to propagate to the reservoir via the conduit, where the impact pressure is generated by a collision process between an object arranged outside of the fluid and the first wall parts for the first wall part to impact on the fluid in the chamber. Further, the chamber is arranged to avoid a build-up of gas-inclusions where the first wall part impacts on the fluid. This may be obtained by arranging the conduit in or adjacent to the zone where the gas-inclusions naturally gather by influence of the gravitational forces, or by placing the first wall part impacting on the fluid away from this zone. The invention further relates to a system for the generation of impact pressure. | ||||||

| 209 | Hydraulic Pulse Valve With Improved Pulse Control | US13950063 | 2013-07-24 | US20130306319A1 | 2013-11-21 | Jack J. Kolle |
| Hydraulic pulses are produced each time that a pulse valve interrupts the flow of a pressurized fluid through a conduit. The pulse valve includes an elongate housing having an inlet configured to couple to the conduit to receive the pressurized fluid, and an outlet configured to couple to one or more tools. In the housing, a valve assembly includes a poppet reciprocating between open and closed positions, and a poppet seat, in which the poppet closes to at least partially block the flow of pressurized fluid through the valve. A pilot within the poppet moves between disparate positions to modify fluid paths within the valve. When the valve is open, a relatively lower pressure is produced by a Venturi effect as the fluid flows through a throat in the poppet seat, to provide a differential pressure used to move the pilot and poppet. An optional bypass reduces the pulse amplitude. | ||||||
| 210 | Enhancing well fluid recovery | US11852619 | 2007-09-10 | US08584747B2 | 2013-11-19 | David Eslinger |

| 211 | Injection of liquid into boreholes, with suckback pulsing | US13120271 | 2009-09-24 | US08567505B2 | 2013-10-29 | Brett Charles Davidson |
| When injecting liquids into the ground, imposing pulses on the injected liquid is effective to increase penetration and saturation of the ground. Imposing suckback onto the pulses is effective to make the liquid in the ground behave as a coherent unitary body, surging out and back each pulse, and to super-saturate the ground. The tool includes a suckback-chamber, which is timed to open to the ground formation just as the pulse-valve closes. A biasser (e.g a spring) drives the chamber open and sucks in some of the liquid from the ground. The chamber is then emptied, back to the ground, by the rising pressure as the pulsing tool is recharged. The suckback-chamber can be added to any type of pulsing tool. | ||||||

| A method of deep acid stimulation for a zone to be treated in an underground formation using an acidizing tool, the method including the steps of introducing the acidizing tool into the well bore, introducing the acid formulation onto the well bore wall at the treatment zone and introducing ultrasound energy into the underground formation at the treatment zone. The subsequent acid penetration depth is deeper than the initial acid penetration depth. A method of stress fracturing a portion of an underground formation includes the steps of introducing the acidizing tool into a well bore and introducing the acid formulation and the ultrasound energy at the focused treatment point. The weakened acidized spots in combination with the stress on the underground formation causes oriented stress-induced fractures to form that are fluidly coupled with the well bore.

| 218 | USING MICROSEISMIC ACTIVITY TO FACILITATE HYDROCARBON PRODUCTION IN TIGHT SAND AND SHALE RESERVOIRS | US13441888 | 2012-04-08 | US20130075086A1 | 2013-03-28 | Frank PRESS |
| Naturally occurring microseismic events are monitored and utilized to synergistically augment a hydraulic fracturing process. Such events generally originate from the tidal dilational stress that makes it easier for fractures to open and slip. If the hydraulic fracturing process can be scheduled to occur coincident with elevated levels of naturally occurring microseismic activity, the efficiency of hydraulic fracturing can be increased. Accordingly, the resources consumed and the byproducts produced by the hydraulic fracturing process will be reduced as will be other elements of environmental damage. In like manner, where hydraulic fracturing cannot be used, the natural dilational stress may be synergistically enhanced with induced hydraulic pressures that are below the pressures required for conventional hydraulic fracturing. These periods of elevated microseismic activity may also be predicted based on natural cyclic phenomena, such as peak earth tides, which are known to be correlated with periods of higher microseismic activity. | ||||||
