Abstract: A steering collar for deflecting a drill string in a borehole to cause the borehole to be drilled in a different direction. The steering collar surrounds a hollow drive shaft which is driven by the drill string. During normal drilling operations, the steering collar does not rotate with the drive shaft. The steering collar has three sets of pistons operated by the pressure of the drilling fluid, one set of which is pressure relieved. Drill fluid that is pumped down the drill string flows into the hollow drive shaft and through ports to activate the pistons which thereby force corresponding pads outwardly into contact with the sidewall of the borehole. Since the one set of pistons is pressure relieved, it does not force its pad against the borehole sidewall with as much pressure as the other two sets of pistons force their pads against the sidewall of the borehole.

Abstract: A method of installing a pressure transducer in a borehole to measure the fluid prepare of a geological formation. The pressure transducer is installed into the borehole at a desired depth, and then the borehole is filled with a cement grout. The fluid connection between the pressure transducer and the formation is opened by pumping a fluid through tubing to displace the cement grout. A process of hydrofracture can be employed to provide a communication path of fluid between the formation and the pressure transducer surrounded by the fractured grout. In one embodiment of the invention, a pressure transducer is cemented into the borehole along with a check and pressure relief valve. In another embodiment, the pressure transducer is installed in the tubing at a subsequent stage.

Abstract: A method of degassing a coal seam by directionally drilling a borehole in a rock formation that is adjacent the coal seam, or between two different coal seams. The borehole is then pressurized to fracture the adjacent coal seam(s) to enhance the permeability thereof and allow fluids to flow from the coal seam to the borehole and be extracted from the coal seam.

Abstract: A gas analysis system for determining the gas content of subterranean strata. A boring operation is commenced to form a borehole into or through a subterranean formation, such as a coal or shale formation to determine the gas content thereof. The drill fluid, cuttings and any desorbed gas is carried from the downhole location to surface analysing equipment in a closed system, so that the desorbed gases are not exposed to the air. The drill stem is capped or sealed at the surface, as well as the wellbore annulus to effectively seal the drill liquid, cuttings and desorbed gasses. The drill fluid, cuttings and desorbed gasses from the formation are coupled from the wellhead apparatus to the gas processing equipment via a closed system so that the constituents and volume of the gas can be determined.

Abstract: Method of consolidating sand in a subterranean formation by contacting the sand in a first location in the presence of water with a slurry in a liquid medium of cement of average particle size less than 10 microns to produce a mixture including sand, water and cement, the slurry being injected into the formation to the location. A separation step is carried out in which a liquid hydrocarbon fluid is passed into the location to displace from the location at least some of the cement from the mixture. The volume ratio of liquid hydrocarbon fluid to the volume of the slurry injected to the formation is at least 5:1. The mixture is allowed to set to give permeable consolidated sand.

Abstract: A water supply system that supplies water to a plumbing system from either a mains supply, or an auxiliary supply. In a default state, a shuttle valve is pressure balanced and couples water from the mains supply to the plumbing system via mains inlet port and outlet port, and in another state the shuttle valve is pressure unbalanced and moved so that auxiliary water is coupled to the plumbing system via an auxiliary inlet port and the outlet port of the shuttle valve. Water is drawn from an auxiliary tank and coupled to the plumbing system when two conditions exist, namely when water is demanded, as sensed by flow sensor, and when water is available from the auxiliary supply, as sensed by float system. Water pressure at the auxiliary inlet port causes the shuttle to move from the default state and couple water from the auxiliary inlet port to the outlet port and thus to the plumbing system.

Abstract: Drill stern test apparatus includes a drill string, wireline coring system and a downhole tool that is seated in the core barrel of the coring system. A valve packer within the downhole tool is inflated to seal the core barrel and allow a valve to be operated by movement of the drill string. One or more packers can be inflated to isolate the test zone in the borehole below the coring system. The apparatus is operated to allow the test zone fluid to flow upwardly in the downhole tool and be measured. Downhole tool transducers accumulate the data and transmit the same to the surface. The wireline can be pulled to relieve packer inflation pressure, release a latch and allow the downhole tool to be pulled to the surface while leaving the coring system in place.

The poly(meth)acrylate linking group has a number average molar mass in the range of 600 to 40,000 g mol?1.

Abstract: The invention is a separator designed to separate an incoming stream of liquid, gas, and some particulate matter into a separate gas stream, and a separate liquid stream containing the particulate matter. This is achieved through cyclonic action and the use of a float to operate internal valves within the cyclone. The float is mounted on a shaft which is rotated by the motion of the incoming fluid stream and this motion is used to agitate the solids in the liquid so as to prevent the outlet port from becoming jammed. The outlet port also has an auger contained therein that removes particulate matter.
