Abstract: A rotary blowout preventer has a first and a second fluid circuit. Each of the fluid circuits are defined into and out of a stationary body and between the stationary body, a rotating body, and two seals. The first fluid circuit is physically independent from the second fluid circuit although they share a seal interface. A fluid is introduced into the first fluid circuit at a pressure responsive to the well bore pressure. A fluid is introduced into the second fluid circuit at a pressure responsive to and lower than the pressure of the fluid in the first circuit. Adjustable orifices are connected to the outlet of the first and second fluid circuits to control such pressures within the circuits. Such pressures affect the wear rates of the seals. The system can therefore control the wear rate of one seal relative to another seal. A thrust bearing is added to share the load placed upon the upper bearings. The thrust bearing is connected between the top end of a packer sleeve and the stationary body.

Abstract: A conventional land drilling rig is interconnected to the substructure for an oilfield pad location. The interconnected drilling rig is placed on top of matting. The matting has embedded rollers to facilitate movement of the drilling rig as a “convoy” across the mat from one wellhead to another wellhead. The buildings in the mud tank system may also be interconnected and move in a separate convoy but in tandem with the first convoy.

Abstract: A variety of types of wood matter may be used as a starter material. The starter material is processed into wood pieces in the range of about twenty mesh to six inches to form a base product. The base product is installed in windrows along the beach. A fence may be installed between the windrow(s) and the water.

Abstract: The invention relates to a method and an apparatus for use in surveying boreholes. The method of the invention comprises the following steps: providing an instrument package in a leading end of a drillstring, the instrument package comprising first and second single-axis sensors mounted for rotation with the drillstring about the rotational axis of the drillstring, the first sensor being an accelerometer and the second sensor being a magnetic fluxgate or a rate gyro; rotating the drillstring; deriving from the first sensor the inclination angle of the drillstring at the instrument package; and deriving from the second sensor the azimuth angle of the drillstring at the instrument package.

Abstract: A borehole drilling and survey assembly includes a drill string of magnetic material, a non-magnetic drill collar, and a non-magnetic rotary drilling system including a drill bit. A near-bit survey instrument is located in the rotary drilling system at a fixed distance from the junction of the drill string and the drill collar. A second survey instrument is located in the drill collar at a fixed distance from said junction. The survey instruments measure the local values of the component of the earth's magnetic along the borehole axis, and these values are processed to remove the magnetic effects of the drillstring. The survey instruments optionally also measure gravity vector components to enable borehole heading to be derived.

Abstract: A torsional shock absorber dampens rotary shock loading on a well drill string. An outer housing has drive splines on an inner surface. A mandrel is located within the outer housing and has drive splines on an outer surface that fit between the drive splines on the inner surface of the housing. Dampening bars are positioned longitudinally between the splines of the outer housing and the splines of the mandrel to absorb shock from non-uniform torsional loading at the drive interface between the outer housing and the mandrel. A balancing piston is located within the tool to compensate for pressure difference between drilling fluid pressure and lubricant contained within the shock absorber. A thrust bearing assembly is provided to accept axial thrust loads from the outer housing and transfers the load to the splined mandrel. A retainer transfers tensile loads from the housing to the mandrel through the thrust bearing.

Abstract: A device for producing a jet of water has a portable handheld water reservoir to be filled with warm or cold water manually by the user, a battery powered handheld air or water pump to create water pressure for the generation of water jet which is delivered through a handheld nozzle system, a thin flexible disposable nozzle protector for sanitary protection of the non-disposable nozzle and nozzle tip, and an optional new medicine dispenser on the nozzle system.

Abstract: A breathing filter with a nose mask, strap(s), and a filter member. The strap(s) are elastic, and serve to hold the nose mask over the user's nose. The filter member is a plug-in device allowing removal of the filter member and replacement of the filter member cartridge or the filter material.

Abstract: The present invention is a propagation resistivity system that utilizes one or more transmitter coil antennas, or “transmitters” and at least two receiver coil antennas, or “receivers”. The system uses a wellbore resistivity tool which may be embodied as a MWD tool or as a wireline tool. Two or more transmitters may be spaced equally on either side of two or more spaced-apart receivers. Two or more frequencies are transmitted and received simultaneously. Multiple frequencies may be transmitted from each transmitter or from separate transmitters at the same time. Multiple frequencies are simultaneously received and analyzed by the receiver electronics, thereby reducing the measurement time for multiple frequency measurements. In one embodiment each of two transmitters transmits simultaneously. One transmitter operates on a high frequency. The second transmitter operates at a lower frequency.

Abstract: A drilling tool has a bent sub or a defined “High Side”. An instrument housing which includes a magnetometer is secured to the directional drilling tool. The magnetometer measures the magnetic field vector in the plane perpendicular to the tool axis. Prior to running the directional drilling tool and the instrument housing into the well, a magnetic source is positioned next to the instrument housing at a position near the magnetometer. The magnetic source is made and positioned such that its magnetic field at the magnetometer points to the chalk line of the high side of a bent sub. The net magnetic field generated from the source is obtained by the difference in magnetic field measurements before and while the magnetic source is applied The azimuthal angle between the net magnetic field vector and the x-axis of the magnetometer or other direction sensor reference point used for tool face calculation is obtained by a computer.

A vacuum is produced within the temperature controlled package.

Abstract: A method for producing a vacuum, which includes feeding an ejecting vaporous medium into the gas ejector, evacuating an ejected gaseous medium by the ejecting vaporous medium, mixing of the vaporous and gaseous mediums and forming a mixture of the two, evacuating this mixture by a liquid-gas ejector whose nozzle is fed by a liquid ejecting medium, condensing the vaporous ejecting medium and its dissolving in the liquid ejecting medium in the liquid-gas ejector, forming a liquid-gas mixture and subsequent separating the liquid-gas mixture into compressed gas and a liquid phase which is used further as the liquid ejecting medium of the liquid-gas ejector. Substances which are reciprocally soluble in each other or mixtures of such substances are used as the vaporous and liquid ejecting mediums.

Abstract: In the field of jet technology a nozzle of a liquid-gas jet apparatus for feed of an active liquid medium has a central channel and a peripheral annular channel and the total surface area of the outlet cross-section of the nozzle channels is determined from the following formula: S=S&mgr;(1+{square root over ((Skc/S&mgr;)3)}), where S—is the total surface area of the outlet cross-section of the nozzle; S&mgr;—is the surface area of the outlet cross-section of the central channel of the nozzle; and Skc—is the surface area of the minimal cross-section of the mixing chamber. A liquid-gas jet apparatus with the above-mentioned features has a higher efficiency and an improved reliability.
