  • Patent number: 9869157
    Abstract: Reverse circulation cementing of a liner in a wellbore extending through a subterranean formation is presented. A running tool with expansion cone, release assembly, annular isolation device, and reverse circulation assembly is run-in with a liner. The annular isolation device is set against the casing. A valve, such as a dropped-ball operated sliding sleeve valve, opens reverse circulation ports for the cementing operation. The liner annulus is cemented using reverse circulation. The expandable liner hanger is expanded into engagement with the casing. Conventional circulation is restored. The running tool is released and pulled from the hole.

  • Patent number: 9651536
    Abstract: A method and system for measuring multiple soil properties on-the-go is provided on an implement for traversing a field. An optical module is carried by the implement for collecting soil reflectance data. A pair of soil contact blades protrude from or are embedded in the optical module for collecting soil EC data and soil moisture data. A switching circuit or phase lock loop allows the same soil contact blades to feed signals to both a soil EC signal conditioning circuit and a soil moisture signal conditioning circuit. The soil moisture data can be used to calibrate the soil EC data and the soil reflectance data to compensate for effects of changing soil moisture conditions across a field. The system can also be used on a planter to control planting depth and/or seeding rate in real time based on multiple soil properties collected during planting.

  • Patent number: 8904703
    Abstract: Apparatus and method for boring into the earth near a Kudzu vine root system to apply herbicidal helium gas to the roots and eradicate the Kudzu vine. The technique uses a perforated tube with a drill bit that protrudes from one end of the tube to bore into the earth near the vine roots. Boring is stopped when all of the tube perforations are below the earth's surface. About 0.5 cubic meters of helium gas are applied to flow through the tube enabling the helium gas to flow out through the tube perforations and attack the Kudzu vine through the vine's root system.

  • Patent number: 6098448
    Abstract: An apparatus and method for discrete soil gas and saturated liquid permeability measurements with direct push emplacement systems (such as a cone penetrometer rod). A modified direct push emplacement system having at least one injection port and at least two measurement ports is first engaged to penetrate the soil to a predetermined depth. Gas or liquid is then injected into the soil at a predetermined location on the penetrometer rod. Next, a pressure response is recorded from each measurement port, which is at a known distance from the injection port (on the same penetrometer rod). This differential pressure response data allows calculation of the soil permeability directly by using a one-dimensional, spherical, steady state, porous flow model to measure the effective permeability of the soil, without substantial disturbance of the surrounding soil. The present invention minimizes false indications of reduced permeability as a result of soil compaction during the penetrometer emplacement.

  • Patent number: 5570748
    Abstract: A drill bit (10) for drilling geophysical exploratory holes using a non-rotating drill approach is disclosed. The bit (10) includes a tubular body (12) threaded at one end for engagement with a pipe stem. The elements (16a -b) of a divided conical tip (14) are hinged to a second end (20) of the bit body (12). The wall thickness of the bit body (12) gradually increases from the first end (18) to the second end (20) to create, when the divided elements (16a-b) of the tip are closed, a generally diamond-shaped cross section facilitating burrowing when forced into the soil. An O-ring (36) installed in a groove (34) about the outer circumference of the tip (14) biases divided elements (16a-b) closed until a selected tool is loaded through the interior of the bit body (12), whereupon the divided elements (16a-b) are forced to rotate radially outward. The bit (10) can then be raised and removed from the borehole as desired.

  • Patent number: 5548991
    Abstract: Relative permeability of subsurface earthen materials is measured by advancing a probe into the earthen material at a constant rate while simultaneously injecting a fluid sealant/lubricant, or vapor, or liquid, from the probe to the earthen material. The relative permeability of the earthen material is determined by measuring either changes in flow rate or pressure of the injected vapors or fluids. The prescribed method of operation of the probe seals the probe hole allowing collection of discrete vapor samples and also greatly facilitates advancement of the probe.

  • Patent number: 5503031
    Abstract: A ground water sampling device has an elongated cylindrical hollow housing positioned at a desired depth below the ground surface. The housing has an opening formed at its lower end and an inner surface with an annular groove disposed adjacent the opening. The device has an elongated screen capable of being telescopically received in the housing and capable of being deployed through the opening of the housing. The screen has an annular slot formed on its outer surface adjacent its upper end. A resilient locking collar is compressed inwardly and received in the slot of the screen when the screen is received in the housing prior to its deployment. The collar expands outwardly into the groove of the housing when the slot of screen is longitudinally aligned with the groove during deployment of the screen. The collar in its expanded position is disposed in both the slot and the groove so that the screen is locked in its deployed position.

  • Patent number: 5435176
    Abstract: A mobile hazardous waste characterization system having a top driven rotary kelly bar and drill bit in conjunction with a non-rotatable casing surrounding the kelly bar in which the casing and waste contamination sensing probes affixed thereto are supported by the top drive and are moved into and out of the site with the kelly bar and drill bit. The sensors preferably are optical soil contamination probes affixed to the casing to qualitatively and quantitatively determine soil contaminants and monitor remediation progress in situ at a subsurface soil characterization and treatment location. Soil gas sampling and a solid soil core sample removal device may be integrated with the optical contaminant sensing for accurate site characterization and simultaneous remediation thereof.

  • Patent number: 5402855
    Abstract: Low-cost, medium-curvature, deviated drainholes are drilled from a vertical cased well in soft formations, using the jet-drilling technique with a coiled-tubing. The high-velocity liquid jet is oriented at a small angle from the axis of the coiled tubing in the selected direction. The jet nozzle assembly is held by a pin in a reference groove in the tubing wall, parallel to its axis. A similar pin in a conventional sonde containing orientation sensors is also inserted in the same groove, so that the jet's spatial orientation is fully determined, with respect to the vertical and North. The jet angle with respect to the tubing axis is pre-set by mechanical or hydraulic locking devices and periodically re-adjusted, based on the sonde's spatial orientation data.

  • Patent number: 5301758
    Abstract: A method and apparatus for enlarging a straight or arcuate pilot bore hole and the insertion of tubing in the enlarged bore is disclosed, in which the pilot bore hole 10 is enlarged by advancing a larger diameter housing with a conical enlarging head by impacting of a striking body mounted within a housing against the inside of the enlarging head at the forward end of the housing. Fluid jet cutting action is also employed and the pilot hole boring device may be coupled to exert a steady pull on the housing as it is advanced through the pilot bore. The housing may thus be connected to the pilot bore drilling device, with an interposed cushioning device. The fluid jets may be created by nozzle openings in the enlarging head or in a separate device mounted forward of the enlarging head.
