Abstract: The present disclosure provides systems, tools, and methods for enhancing a measurement of a fluid in a borehole, pipe, conduit and/or the like. The systems, tools, and methods may involve an electromagnetic measurement tool that includes a transmitting antenna configured to transmit electromagnetic energy, a receiving antenna configured to receive the electromagnetic energy, and a metamaterial element comprising a negative refractive index. The metamaterial element may focus the electromagnetic energy. The electromagnetic system may comprise one or more antennas that are disposed adjacent to or in contact with the fluid, electromagnetic energy may be transmitted via the transmitting antenna, and the electromagnetic energymay be received with the receiving antenna to measure a property of the fluid.

Abstract: Fracture monitoring and characterisation of a subterranean fracturing process is described. Hydraulic fracturing conditions intended to induce tensile crack opening or compressional crack closure of a fracture responsible for a microseismic event in the Earth formation are selected and a hydraulic fracturing operation is performed using the selected conditions to cause tensile crack opening or compressional crack closure of the fracture responsible for a microseismic event in the Earth formation. Induced motion data from the microseismic event is received using a plurality of receivers, and the received data is analysed to track the development of the fracture responsible for the microseismic event and/or to track a proppant distribution within the fracture.

Abstract: A computer-implemented method for determining elastic properties for a heterogeneous anisotropic geological formation is described herein. The method includes grouping sonic velocity data from a borehole section (or borehole sections) into a number of clusters (e.g., one or more clusters). The sonic velocity data is grouped into clusters using petrophysical log data from the borehole section. The method also includes inverting the sonic velocity data for the clusters to determine elastic properties for each cluster. In some cases, the elastic properties for the clusters are combined to determine a relationship between the elastic properties and formation heterogeneity.

Abstract: Braking systems and methods are provided for a drum winch system having a winch drum having an outer surface and a winch drum braking system. The winch drum braking system has a first brake having a first brake lining, located adjacent to the winch drum, and a first three-ring ratchet linkage system connected to the first brake lining. The first three-ring ratchet linkage system is rotatable and adapted to move the first brake lining to a first position or a second position with respect to the outer surface of the winch drum. In the first position, the first brake lining contacts the outer surface of the winch drum to apply break force thereon, and, in the second position, the first brake lining is separated from the winch drum.

Abstract: Systems and methods are provided for determining a property, e.g., density, of a geological formation based on Einstein's theory of gravitation. A gravitational potential difference is determined between two positions of the geological formation by measuring a frequency shift of radiation travelling from a source to an absorber of a differential gravimeter. The differential gravimeter can be a part of a downhole tool. The gravitational potential difference determined can be used to determine the property of the geological formation.
