  • Patent number: 11125671
    Abstract: Fracture porosity and permeability variations with increasing effective stress, are measured and determined by laboratory testing of rock cylindrical core plugs of various types (carbonate, silico-clastic, shale, e.g.) and dimensions. The testing can be implemented for both natural and induced fractures propagating axially in the rock core plug. The testing begins with initial testing, sample preparation and obtaining measurements on an intact plug to define matrix properties in the rock core plug. A rock core plug with defined matrix properties is then after further preparation, subjected to an axial shear fracture (natural or induced) propagating through its body. Measurements are then obtained from the plug with an axial shear fracture (natural or induced) propagating through its body to determine fracture properties.

  • Patent number: 11125909
    Abstract: Embodiments of the present invention help in the processing and interpretation of seismic survey data, by correlating or otherwise comparing or associating seismic data obtained from a seismic survey with flow information obtained from a well or borehole in the surveyed area. In particular, embodiments of the present invention allow for flow data representing a flow profile along a well that is being monitored by a distributed acoustic sensor to be determined, such that regions of higher flow in the well can be determined. For example, in the production zone the well will be perforated to allow oil to enter the well, but it has not previously been possible to determine accurately where in the production zone the oil is entering the well. However, by determining a flow rate profile along the well using the DAS then this provides information as to where in the perforated production zone oil is entering the well, and hence the location of oil bearing sands.

  • Patent number: 11118243
    Abstract: The invention discloses a measurement apparatus for measuring a volume of a desired solid component in a sample volume of a solid-liquid slurry. The sample volume of the slurry is received into a receptacle and screened to separate out the desired solid component from a remainder of the slurry, whereby the solid component is retained in the receptacle to form a bed therein and the remainder is exhausted. The height of the bed is subsequently measured by a laser being adapted to emit a laser beam into the receptacle, thereby enabling a determination of a volume and/or mass of the solid component retained in the receptacle. The invention further discloses a control system for a leaching plant utilising the measurement apparatus.
