Abstract: A fracture model for a hydraulic fracture in a wellbore can be updated and calibrated. Information about a microseismic event can be received from a sensor that is monitoring a subterranean formation. The information can be received subsequent to a fracking fluid being introduced into the formation. An observed geometry of a hydraulic fracture can be determined based on the information and a predicted geometry of the fracture can be determined based on properties of the fracking fluid and a fracture model. The fracture model can be updated using the information about the microseismic event where it is determined that an uncertainty value of the observed geometry does not exceed a pre-set maximum. The uncertainty value can be based on the predicted geometry of the hydraulic fracture.

Abstract: In some embodiments, an apparatus and a system, as well as a method and article, may operate to determine a change in fracture volume in a geological formation over a selected time period. Further activities may include determining injected fluid loss as an amount of lost fluid over the selected time period, based on the change in fracture volume, selecting a fluid loss model as a selected model based on the amount of lost fluid, and operating a controlled device based on the selected model. Additional apparatus, systems, and methods are disclosed.

Abstract: Uncertainty in microseismic monitoring sensor data can be reduced. A computing device can receive information about at least one sensor that is monitoring a subterranean formation, including a location, after a fracturing fluid is introduced into the formation. The computing device can also receive information about a microseismic event and determine a seismic ray bath between a location of the event and the at least one sensor, and an uncertainty value of the location based on information about the formation and the information about the event. The computing device can determine a total uncertainty value associated with the locations of a plurality of microseismic events, including the microseismic event. The computing device can determine a solution to an objective function based on the total uncertainty value and a number of sensors. The computing device can determine a new location of the at least one sensor based on the solution.

Abstract: An example method for optimized rotation of a drill string coupled to a drill bit and disposed within a borehole may comprise determining an angular velocity of at least part of the drill string. An angular velocity threshold to avoid static friction may also be determined. Additionally, a minimum input torque to apply to the drill string to maintain the angular velocity at or above the angular velocity threshold may be determined. The method may further include generating a control signal to a top drive motor based, at least in part, on the minimum input torque.
