| An improved sonic wave generating device and method transmits variable wave energy to a fluid medium that is transmitted to objects such as subsurface petroliforous formations to be treated. Reverberative pressures and wave energy are reduced by improvements to and from a positive pressure supplied feed pump which pumps the medium to the primary wave generating pump(s) includes means to maintain an increased hydrostatic or positive head to the suction inlet of the feed pump which prevents or neutralizes feed back energy waves from the wave generating device to the feed pump, along with a check valve located at the inlet to the primary pump(s) and a buffer system of conduits located between and in the outlet from the feed pump and the check valve to prevent and dampen recoiling energy waves produced by the pumps and augmenting cavitation valve system. Such apparatus and methods delivers kinetic energy resulting in stress against and into the interstices of the formation to produce virtual work strain and deformation, followed by periodic relief of the stress, thus releasing the potential energy of and within the formation to produce fatigue failure thereof. | ||||||

| 268 | Process for increasing the degree of oil extraction | US84793 | 1987-07-08 | US4884634A | 1989-12-05 | Olav Ellingsen |
| 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 frequeny pulses causing the reservoir to perform like an electrode furnace. | ||||||
| 269 | Rod string sonic stimulator and method for facilitating the flow from petroleum wells | US173248 | 1988-03-24 | US4817712A | 1989-04-04 | Albert G. Bodine |
| A close fitting piston of a material such as rubber is attached to the end of a rod string such as a sucker rod which is suspended inside a tubing string installed in an oil well. An orbiting mass oscillator is attached to the upper end of the rod string and is operated at a frequency such as to cause resonant standing wave vibration of the rod string. The piston member attached to the bottom end of the rod string is driven by the vibrational energy to in effect form an acoustical piston which is driven by the vibrational energy. This energy is coupled to the surrounding liquid and thence to the surrounding formation to effectively unclog the well and the casing string of contaminants which may be impeding the flow of effluent from the well. The piston means is made long enough so that it operates as an acoustic monopole with both ends of the piston being vibrationally in phase with the vibrational energy traveling in the surrounding liquid medium. | ||||||
| 270 | Downhole oil well vibrating system | US47267 | 1987-05-08 | US4788467A | 1988-11-29 | Eric D. Plambeck |
| A transducer assembly includes a piezoelectric transducer and a support member encasing the transducer. The transducer and the support member may have commonly disposed openings. The support member has a progressively increasing thickness at progressive positions from the opening to distribute equally the stresses at the different positions on the piezoelectric transducer. A plurality of such transducer assemblies may be disposed at spaced positions in an oil well with the support members supported on a support rail extending through the well. The support rail serves as an electrical ground. A bus bar extends through the well at positions corresponding substantially to the centers of the transducer assemblies. The bus bar is supported by electrically insulating spacer members extending from the support rail. A ring is supported at one end by the support rail and is coupled at the other end to a tubing. The tubing envelopes, the transducer assemblies, the support rail, the bus bar and the spacer members. An assembly including a housing, a piston and a spring respond to changes in the temperature and pressure of the fluid in the oil well to prevent the fluid from cavitating with increases in temperature or pressure. | ||||||
| 271 | Sonic impeller for sonic well pump | US787492 | 1985-10-15 | US4695231A | 1987-09-22 | Albert G. Bodine |
| Within a tubing string forming a conduit for a well is a rod string having sonically responsive impeller pump elements mounted thereon. The impeller pumps employ an elongated cylindrical structure which is spaced from the inner wall of the conduit to form an elongated annular liquid filled gap between the impeller and the conduit. The rod is sonically driven so that it vibrates resonantly. Valves are formed in the impeller, which in one embodiment may comprise a series of ball elements, in another, may comprise flexible reeds, these valve elements being opened and closed in response to the sonic energy to implement the pumping action, and in a third embodiment may comprise arcuate segments that are free to expand and contract radially in response to the sonic energy. The fluid annulus formed between the impeller and the conduit forms a fluid dynamic seal which effectively prevents leak-back flow past the impeller in view of the inertia provided by this annulus which effectively presents a large acoustic mass reactance to the sonic energy. Thus, such leak-back flow is prevented without the need for sealing engagement between the impeller and the conduit. | ||||||
| 272 | Sonic pressure wave pump with liquid heating and elevating mechanism | US877456 | 1986-06-23 | US4687420A | 1987-08-18 | Arthur Bentley |
| A pump for heating high viscosity oil and elevating it to a ground level from a subterranean level. The pump, which is preferrably of the type which produces and is operated by sonic pressure waves of special character, includes a ground level generator for producing pump operating forces that are transmitted to the subterranean level for reciprocally operating a subterranean heating and oil elevating unit which has a special magnetic piston reciprocal in a non-permanently magnetizable housing for generating heat and further has a reciprocal operating mechanism for intaking the heated oil and elevating it to the ground level. | ||||||
| 273 | Method of oil recovery | US764718 | 1985-08-12 | US4648449A | 1987-03-10 | William M. Harrison |
| A method of recovering petroleum fluids from an underground reservoir comprising the steps of: injecting into the reservoir a substantially water insoluble gas; generating and directing soundwaves into the reservoir to release petroleum fluids retained therein; and producing the released petroleum fluids through a well communicating with the reservoir. In an alternate embodiment of the invention, after sufficient water insoluble gas is injected forcing water in the reservoir downwardly and forming a water/oil/gas interface, water and/or oil soluble gas may be injected into the reservoir. | ||||||
| 274 | Clamping jaw device for well servicing machine | US571736 | 1984-01-18 | US4621688A | 1986-11-11 | Albert G. Bodine |
| A clamping jaw device is used to couple sonic energy generated by an orbiting mass oscillator to a pipe string for transmission down the string to a downhole work area. The clamping jaw device includes a pair of similar clamping jaws, each forming a half section of a hollow cylinder. The jaw device has a head portion, a main body portion, a neck portion joining the head portion to the main body portion and indented from the head portion and a flange at the bottom end of the main body portion. The pipe string is retained between the jaws by means of a jaw lock member which comprises a flat ring slidably mounted on the main body portion and adjustably positionable therealong, the lock member being seated against the flange at the bottom end of the main body portion to hold the jaws in a closed clamping position against the pipe string. The clamping jaws may be firmly clamped to the pipe string so that sonic energy is delivered thereto throughout the vibration cycle of the oscillator by means of hold down screws. | ||||||

| 276 | Apparatus and method for installing well casings in the ground employing resonant sonic energy in conjunction with hydraulic pulsating jet action | US599969 | 1984-04-13 | US4548281A | 1985-10-22 | Albert G. Bodine |
| A well casing to be installed in the ground is resonantly driven at a sonic frequency by means of an orbiting mass oscillator. A wedging probe member is optionally attached to the end of the casing and is driven by the vibratory energy to facilitate the penetration of the earthen material ahead of the casing. A closure wall is fitted to the bottom of the casing, this closure wall having jet nozzles formed therein. While the casing member and probe member are being vibratorily driven by the sonic energy, pulsating jets of water are emitted through the jet nozzles to aid in the cutting of the earthen formation along with the sonic vibratory energy, the sonic energy markedly enhancing the hydraulic jet action by virtue of the pulsating force it imposes on the hydraulic jets. | ||||||
| 277 | Sonic fracing process and means to carry out said process | US503595 | 1983-06-13 | US4537256A | 1985-08-27 | Franklin Beard |
| A sonic fracing process and means to enhance production of oil and gas wells, increasing formation permeability by creating sonic waves that cracks and loosens the formation interstices. The sonic waves are created by a series of directed detonations and harmonic pulsations. The explosive material is placed inside the well bore and detonated from the surface. Two methods commonly used to increase formation permeability are known as Acidizing and/or Hydraulic Fracturing. The Sonic Frac has been designed to complement these fracing processes.Three inherent benefits are derived by using the Sonic Frac Process. First, and most important, is that the fine formation fissures are cracked and "opened" to allow flow of oil or gas to migrate from pores that would otherwise not be affected by conventional fracing processes. Second the pressure pulsations, which are created by the expansion of the gas utilized in conjunction with the Sonic cause the fluid in the wall bore to oscillate through the perforated zones. Third, the head generated by the variable velocities of the sonic waves tend to dissipate and precipitate back into the formation any paraffin or asphaltum deposits which might be clogging the perforations or a main artery of permeability.The device employed includes a tubular housing, cylinders mounted in said housing, pistons in said cylinders, fuel lines connected into said cylinders and a remote controlled firing means in said cylinder, and means for timing the firing so that a series of explosions provide sonic waves in the formation. | ||||||
| 278 | Sonic method and apparatus for augmenting fluid flow from fluid-bearing strata employing sonic fracturing of such strata | US348880 | 1982-02-16 | US4471838A | 1984-09-18 | Albert G. Bodine |
| A device for fracturing earthen material includes an elongated stem member having a wedging tool attached to the distal end thereof and a sonic oscillator coupled to the top end thereof. The wedging tool has rib means formed on the outer portions thereof, these rib means in one embodiment being spaced around the circumference of the tool at approximately 90.degree. intervals. The stem is lowered into a well to be serviced to stimulate the flow of fluid (generally oil) therefrom. With the tool ribs wedged against the sides of the well, sonic energy is coupled from the sonic oscillator into the stem. This energy may be at a frequency such as to cause resonant elastic vibration of the stem. The tool is fabricated of a hard elastic material, such as steel. The sonic energy is coupled from the wedging ribs of the tool to the earthen formation surrounding the well in a non-isotropic manner, i.e., along particular lines. The sonic energy tends to fracture the earthen formation with the tool being driven down the well by virtue of the bias force applied thereto by virtue of its own weight, the weight of the stem and that of the oscillator structure. As the tool is thus driven down the well, the leading edges of the ribs provide a wedging action which gives good acoustic coupling and engenders a splitting action of the earthen formation to loosen the fluid material contained therein. | ||||||
| 279 | Mechanoacoustic transducer for use in transmitting high acoustic power densities into geological formations such as oil-saturated sandstone or shale | US371481 | 1982-04-23 | US4469175A | 1984-09-04 | Frank Massa |
| A mechanoacoustic transducer is described which comprises a plurality of circumferentially spaced contiguous vibratile plate members which are driven in phase by a rotating cylindrical cam. The cam is shaped to provide radial oscillatory displacements of the vibratile plates of sufficient amplitude to generate acoustic power density levels in liquids in the order of 100 kW or more per square foot of radiating surface of the cylindrical transducer. The transducer has a diameter of several inches, and it can be lowered into a flooded hole of such size as is usually drilled in an oil field. The mechanically-driven transducer provides an economical means for transmitting very intense low-frequency acoustic power into an oil-bearing shale or sandstone deposit for the purpose of dislodging the trapped oil and increasing the flow rate out of the sediment within which the oil is entrapped. | ||||||
| 280 | Sonic pressure wave surface operated pump with extensible pumping assembly | US396119 | 1982-07-07 | US4460320A | 1984-07-17 | Arthur P. Bentley |
| A sonic pressure wave surface operated pump is provided with a mechanism for controlled movement of a flexible production tube and pumping assembly into and out of contact with a liquid to be pumped and is provided with a sonic pressure wave generator which produces sonic pressure waves of special character in a column of liquid carried in the pump. The sonic pressure waves are transmitted through the flexible production tube by the column of liquid to the pumping assembly for operation thereof and are reflected by the pumping assembly back through the flexible production tube and carry the liquid being pumped in the same direction. | ||||||
