  • Patent number: 10760236
    Abstract: The present disclosure relates to a method for real-time compensation for ground movements which would otherwise adversely affect an existing built environment. Embodiments may include providing a plurality of holes in soil for the injection of a substance that expands as a consequence of a chemical reaction. The plurality of holes may be located between a source of movement and an asset to be protected. Embodiments may also include injecting, in at least one of the plurality of holes, the substance and monitoring, in real-time, at least one of movement of the soil or the asset to be protected. Real-time monitoring may occur during an activity that is causing the ground movements. Embodiments may further include obtaining real-time monitoring data, based upon, at least in part, the monitoring.

  • Patent number: 10351770
    Abstract: Polysaccharides may be partially oxidized by oxidative opening of a monosaccharide unit while still retaining glycosidic bonds. Such polysaccharides may be further functionalized with an amine moiety at a site of oxidative opening. Polysaccharides that are partially oxidized and amine-functionalized in this manner may be combined with an aqueous liquid to form compositions suitable for stabilizing clays in clay-containing formations. Clay stabilization may promote reduced swelling of the clays in the presence of water.

  • Patent number: 6843331
    Abstract: A method and apparatus for controlling drilling mud density at a location either at the seabed (or just above the seabed) or alternatively below the seabed of wells in deep water and ultra deep water applications combines a base fluid of lesser density than the mud required at the wellhead to produce a diluted mud in the riser. By combining the appropriate quantities of drilling mud with base fluid, a riser mud density at or near the density of seawater may be achieved. A wellhead injection device for attachment to the wellhead is used for injecting the base fluid into the rising drilling mud at a location below the seabed. The riser charging lines are used to carry the low density base fluid to the injection device for injection into the drilling mud below the seabed. The cuttings are brought to the surface with the diluted mud and separated in the usual manner. The diluted mud is then passed through a centrifuge system to separate the heavier drilling mud from the lighter base fluid.

  • Patent number: 6662885
    Abstract: Disclosed is a method of producing a pressurized stream of substantially inert gas. The method comprises collecting the exhaust gases from an internal combustion engine, directing the exhaust gases into the intake of a compressor for compressing to a desired pressure, and recirculating a portion of the compressed exhaust gases back to the intake of the compressor such that the pressure of the exhaust gases within said compressor intake is maintained above atmospheric pressure. Also disclosed is an apparatus for producing a pressurized stream of substantially inert gas utilizing the described method.

  • Patent number: 6648084
    Abstract: The invention provides a head for injecting a liquid under pressure from a borehole to break up the soil, said head being mounted at the end of a drill string including a liquid feed for feeding a liquid under pressure. The head comprises a body and an outside wall, the body having at least one injection nozzle mounted therein, the nozzle having an inlet diameter equal to d and presenting an axis (x-x′), the body also having a tube. The tube presents a mean line having a first end connected to the bottom end of the liquid feed and having a second end connected to the nozzle tangentially to the axis (x-x′). The mean line is defined by at least one curved portion presenting a radius of curvature that varies continuously. The right section of the tube decreases regularly over at least half of its length from its first end to its second end.

  • Patent number: 6637522
    Abstract: An apparatus and method is provided for substantially continuously drilling and disposing of drill cuttings and dust to minimize airborne contamination while providing protection against overload using enhanced computer control. A drill stem with a bit is used to form the drill hole. A flushing mechanism utilizes vacuum or pressurized water to create a bailing fluid flow for flushing the cuttings and dust from the drill hole for disposal. A transducer monitors at least one first parameter of the bailing fluid flow, and a sensor may also monitor at least one second parameter of a flow of a driving fluid under pressure for feeding the drill stem and bit into the earth. A controller is utilized to regulate the rate of feed and/or driving of the stem and bit dependent on the levels of the parameters being monitored.

  • Publication number: 20030062199
    Abstract: A method of drilling sub-sea oil and gas production wells in which a liquid hydrocarbon substance, such as a natural gas liquid, is injected into the drilling mud supplied to the well in order to reduce the mud density. The method of the present invention enables reduction and control of the hydraulic pressure of the drilling mud while drilling production wells in deep water, thereby to require fewer casing runs which eventually yields better oil productivity.

  • Patent number: 6536540
    Abstract: A method and apparatus for controlling drilling mud density at or near the seabed of wells in deep water and ultra deep-water applications combines a base fluid of lesser density than the mud required at the wellhead to produce a diluted mud in the riser. By combining the appropriate quantities of drilling mud with base fluid, a riser mud density at or near the density of seawater may be achieved. No additional hardware is required below the surface. The riser charging lines are used to inject the low-density base fluid at or near the BOP stack on the seabed. The cuttings are brought to the surface with the diluted mud and separated in the usual manner. The diluted mud is then passed through a centrifuge system to separate the heavier drilling mud from the lighter base fluid.

  • Patent number: 6467558
    Abstract: Three air hammers are housed and arranged in a hammer case, and have bits at their respective ends. Each of the air hammers can be activated independently. In a normal excavation, the earth is excavated by activating all the air hammers. When correcting an excavating direction, only an air hammer positioned in the correct direction is activated first so that the earth in the correct direction is excavated in a predetermined amount. Next, all the air hammers are activated to excavate the earth. Thereby, a leading hammer can direct the excavation toward the correct direction, and thus the excavating direction is corrected.

  • Patent number: 6347675
    Abstract: A method for increasing the efficiency of drilling operations by using a drilling fluid material that exists as supercritical fluid or a dense gas at temperature and pressure conditions existing at a drill site. The material can be used to reduce mechanical drilling forces, to remove cuttings, or to jet erode a substrate. In one embodiment, carbon dioxide (CO2) is used as the material for drilling within wells in the earth, where the normal temperature and pressure conditions cause CO2 to exist as a supercritical fluid. Supercritical carbon dioxide (SC—CO2) is preferably used with coiled tube (CT) drilling equipment. The very low viscosity SC—CO2 provides efficient cooling of the drill head, and efficient cuttings removal. Further, the diffusivity of SC—CO2 within the pores of petroleum formations is significantly higher than that of water, making jet erosion using SC—CO2 much more effective than water jet erosion.
