Abstract: A well logging instrument has a fluid chamber at its lower end and a plurality of controlled flow orifices leading from the chamber to the exterior of the instrument. A piston within the chamber, having a spring at its upper end, forces a friction-reduction agent from the chamber through the flow-controlled orifices into the earth borehole to facilitate the movement of the well logging instrument through the borehole. The upper portion of the fluid chamber, above the piston, is also ported to the fluid within the borehole to equalize the pressure across the piston. In an alternative embodiment of the invention, the acceleration of the borehole instrument creates a velocity signal which is compared with the velocity of the logging cable at the earth's surface and upon a sufficient difference in velocity, the friction-reduction agent is caused to be ported into the earth borehole.

Abstract: The vertical or both vertical and horizontal conformance of a steam drive process is improved and steam override reduced by penetrating the zone between one injector and one producer, with one or more infill wells in fluid communication with the bottom half or less of the formation, and producing petroleum from the infill well after steam channeling has occurred at the production well. After the water cut of the fluids being produced from the infill well reaches 95 percent, the infill well is converted from a producer to an injector and steam is injected into the infill well and fluids are recovered from the production well. When one infill well is employed in a more or less aligned arrangement between injection and production wells, the vertical conformance is improved. When one or more infill wells are positioned in an offset or nonaligned arrangement relative to each injector and producer, conformance in both the horizontal and vertical planes is improved.

Abstract: The vertical conformance of a steam drive process is improved and steam override reduced by penetrating the zone between one injector and one producer, with an infill well located between the injector and producer which is in fluid communication with no more than the bottom half of the formation. Steam is injected into the injection well in the first phase with production of fluids from the upper 1/3 or less of the formation via the production well. A separate flow path in communication with the bottom 1/3 or less of the formation is provided in the producing well, and is used during the first phase for push-pull treatment of the formation with solvent and steam or hot water.

Abstract: The vertical conformance of a steam drive process is improved and steam override reduced by penetrating the recovery zone between one injection well and one producing well, with at least one infill well which is in fluid communication with no more than the bottom half of the formation. Steam or a mixture of steam and hydrocarbon is injected into the injection well and fluids including oil are recovered from the producing well until live steam production occurs at the producing well. Petroleum production is then begun at the infill well and continued until the water cut of the fluids being produced from the infill well reaches 95 percent. The infill well is converted from a producer to an injector and hot water or cold water followed by hot water is injected into thelower portion of the formation via the infill well and fluids are produced from the production well. By this means, oil is recovered from the lower portions of the formation between the infill well and the production well.

Abstract: The vertical conformance of a steam drive process is improved and steam override reduced by penetrating the zone between one injection well and one producing well, with an infill well which is in fluid communication with the bottom half or less of the formation, and producing petroleum from the infill well after steam channeling has occurred at the production well; then converting the infill well from a producer to an injector and injecting steam into the lower portion of the formation via the infill well and recovering fluids from the production well. Two separate communication paths are established, one between the surface and the upper half or less of the formation, and one between the bottom half or less of the formation in the producing well, or in the infill well, or injection well, or combination of two or more thereof.

Abstract: A hydraulic rotary percussive drill which is adapted to operate as a drill for installing rock bolts in mines is described. The drill is configured so that the shank (which holds the drill steel and bit) forms a right angle with the impact mechanism, thereby reducing the height of the drill and providing longer lengths of drill steel feed in a confined environment. A hydraulic spring force coupler transfers the impact energy from the impact mechanism to the shank, steel and bit and shapes the energy so as to provide force pulses of such length as to couple efficiently the percussive energy to the rock being drilled while reducing the strain in the steel and bit. A rotation mechanism may be mounted in the same leg of the right angle as the shank, steel and bit to rotate the steel and bit independently from the percussive action.

Abstract: A process for excavating and constructing a tunnel, and an excavating device are disclosed. This process is directed to excavating and constructing a tunnel under a railway or a road on a banking or on level land in the direction transverse to the railway or road. In this process, pits are dug on the opposite sides of the railway, and then an excavator digs into the wall of a pit on one side so as to go out of the wall of the other pit through the ground left therebetween. In this respect, a hollow casing unit of a box shape is coupled to the rear end of the excavator equipped with a screw conveyor. As the excavator advances or digs forwards a given distance, another casing unit is in turn coupled to the rear end of the preceding casing unit, and then such a step is repeated, until the excavator goes out of the wall of another pit. In this manner, the excavator further digs into the wall of one pit in the position adjacent to the preceding run of casing units.

Abstract: Flowable solids are continuously and accurately weighed during transport to a collection or discharge point. A counterweight pivoted conveyor carries a rotating disc at its discharge end, one face of which frictionally engages a relatively stationary comparatively small diameter wheel having a plane of rotation at right angles to the plane of the disc. The disc rises and falls with the pivotal conveyor in response to varying amounts of material on the conveyor, thereby changing the effective radius of the disc relative to the wheel. The wheel activates a counter once during each rotation thereof to register a unit of weight in the counter. The structure is useful in agriculture or industry.
