Abstract: Methods and systems are presented in this disclosure for evaluating whether to apply fluid flowback during a fracture closure stage of a hydraulic fracturing operation of a reservoir formation. Information collected prior to the fracture closure stage of the hydraulic fracturing operation can be first gathered. Based on the collected information, it can be determined whether to perform fluid flowback during the fracture closure stage following a treatment stage of the fracturing operation. Based on the determination, a rate of the fluid flowback can be adjusted and optimized in real-time during the fracture closure stage.

Abstract: Methods and systems for controlling the downhole position and velocity of a work string using a downhole position and velocity controller may be configured or otherwise programmed to account for force compensation. For example, the work string may undergo significant length changes like thermal expansion and elongation or contraction due to inertial forces, self-weight, and wellbore pressure. Also, the downhole conditions (e.g., temperature, internal forces, self-weight, and wellbore pressure) can cause the work string to be overloaded and become damaged if fast or sudden manipulations occur. The dynamic model implemented with the downhole position and velocity controller may be configured to account for the downhole forces experienced by the work string due to downhole conditions to provide the position and velocity movements that should occur at the surface to achieve the desired position and velocity movements downhole.

Abstract: A drilling system includes a top drive having a motor with a rotating shaft and an adjustable torque. The drilling system also includes a connector that couples the rotating shaft to a drillstring. The drillstring system also includes a controller that provides torque commands to the motor, wherein the torque commands are based at least in part on a dynamics model and operate to dampen vibrations due to torsional wave propagation along the drillstring.

Abstract: Uncertainty of microseismic monitoring results can be reduced to improve hydraulic fracture modeling. A computing device can use a fracture model to determine a predicted geometry of a hydraulic fracture in a subterranean formation based on properties of a fracturing fluid that is introduced into the subterranean formation. An uncertainty index of the predicted geometry of the hydraulic fracture can be determined based on an uncertainty value of the predicted geometry and a trend of uncertainty values. When the injection flow rate of the fracturing fluid is less than a maximum flow rate, it can be increased from an initial injection flow rate to an increased injection flow rate in response to determining the uncertainty index exceeds a pre-set maximum.
