International Classification:

H04L 12/58
A63F 13/87
G06F 3/0488

Abstract:

Systems and methods are provided for detecting a gesture made via a display of a first computing device during display of a message comprising first media content, determining that the gesture triggers a second graphical user interface to respond to the message by opening a camera view to capture a second media content, and based on determining that the gesture triggers the second graphical user interface, causing the second graphical user interface to display on the display of the first computing device comprising the camera view. The systems and methods further provide for detecting capture of the second media content via the second graphical user interface comprising the camera view and sending a reply message comprising the second media content in response to the first message.

International Classification:

G01V 1/28
G01V 1/30

Abstract:

A method for locating a microseismic event in a subsurface formation, in some embodiments, comprises: receiving a microseismic signal at a detector; obtaining a velocity model representative of the subsurface formation, the velocity model comprising multiple velocity layers; estimating, for each of the multiple velocity layers in the subsurface formation, a microseismic event location and a microseismic event origin time; and selecting one of the estimated locations and times using a parameter of the microseismic signal received at the detector.

International Classification:

G01V 1/30

Abstract:

Systems, methods, and mediums may implement obtaining baseline traces of a baseline seismic survey and monitor traces of a monitor seismic survey; employing a computer to align the monitor traces to corresponding baseline traces using an error function having a phase-based component, thereby obtaining an aligned monitor survey; generating with the computer a comparison of the aligned monitor survey to the baseline seismic survey; and using the comparison of the aligned monitor survey to the baseline seismic survey to determine a change in the subterranean hydrocarbon producing reservoir.
