  • Patent number: 10408956
    Abstract: A microseismic array includes a series of sensors that are arranged in combinations of various sensor formations that collectively provide an improved radial anti-azimuthal aliasing function for microseismic mapping a wellbore. The sensors may be organized into one or more formations that resemble arms that extend radially outward from a central region around the wellbore, patches distributed in a field around the wellbore, ovals that are centered around the wellbore and concentric rings within the sensor ovals.

  • Patent number: 9443336
    Abstract: A method of proportional highlighting of data is provided. A graph presented on a display includes a first axis, a second axis, and a first value marker that indicates a value determined from data selected for presentation. The first axis includes a minimum value and a maximum value. The second axis includes a plurality of category values. An indicator identifying a subset of the data is received. A proportional value is determined for the first value marker based on the received indicator. A second value marker indicating the proportional value is presented on the graph overlaid on the first value marker when the determined proportional value is between the minimum value and the maximum value. A scale adjustment marker is presented on the graph without adjusting the first axis when the determined proportional value is not between the minimum value and the maximum value.
