Abstract: Methods including the step of producing a bulk fluid from a subterranean formation, the bulk fluid comprising at least water and a hydrocarbon. The bulk fluid is then sampled to form at least one sampled fluid. Next, constituent parameters of the sampled fluid are determined using the hydrophilic-lipophilic deviation (HLD) model. The constituent parameters include the salinity (S) of the sampled fluid, the salinity constant (b); the equivalent alkane carbon number for the hydrocarbon in the sampled fluid (EACN); T is temperature of the sampled fluid; the characteristic curvature for an ionic surfactant composition (cc) or for a nonionic surfactant composition (ccn); the surfactant temperature constant for the ionic surfactant composition (αT) or for a nonionic surfactant composition (cT). Also determining an optimal surfactant or optimal surfactant blend to achieve an oil-water separation morphological phase distribution of the sampled fluid.

Abstract: Reducing or eliminating stick-slip and vibrations downhole may include controlling top drive torque in order to adjust drill bit angular speed in a manner that prevents, eliminates, or reduces stick-slip and vibration. Control methods and systems may include solving one or more optimization problems including an objective function. The objective function may be subject to conditions including a physical model of the drilling system. The objective function may be minimized without reference to a model, but instead by reference to estimated stick-slip frequency based upon a drill bit angular speed profile. In addition, actual downhole measurements for use in control methods and systems, such as drill bit angular speed, may be estimated using an observer.

Abstract: A method for controlling one or more frac pumps of a fracturing spread. The method comprises adjusting a total pump rate of one or more target pumps of the frac pumps to achieve a total rate setpoint for the frac pumps. The method comprises activating one or more trim pumps for an additional pump rate to compensate for a total rate dip occurring when the total pump rate of the one or more target pumps is adjusted.

Abstract: A method for preventing a power blackout of a fracturing spread configured to hydraulically fracture a subsurface formation. The method comprises determining an available capacity of one or more power units that supply power to one or more electric pumps of the fracturing spread. The method comprises determining an actual power usage of the one or more electric pumps. The method comprises determining if the fracturing spread is at risk of the power blackout based on the available capacity and the actual power usage. The method comprises determining one or more actions to mitigate the power blackout; and executing the one or more actions to mitigate the power blackout.

Abstract: A method comprises generating, via a pulse generator, a first pressure pulse in a fluid in a pipe and detecting, via a transducer, a first reflected pressure pulse based on the first pressure pulse, wherein the first pressure pulse is reflected by a pipe feature to generate the first reflected pressure pulse. The method comprises generating, with the pulse generator, a second pressure pulse at a later time relative to generating the first pressure pulse, wherein timing of generating of the second pressure pulse is such that the second pressure pulse is superposed with the first reflected pressure pulse such that an amplitude of the second pressure pulse is greater than an amplitude of the first pressure pulse. The method comprises detecting, via the transducer, a second reflected pressure pulse based on the second pressure pulse, and detecting a pipe feature based on the second reflected pressure pulse.

Abstract: During drilling operations various drilling mud properties may be measured and predicted. Uncertainties in the measured or predicted values may also be calculated. The estimated uncertainties may then be used to optimize mud sampling interval and/or control a mud mixer. A decision making algorithm may be performed to optimize a surface mud sampling interval such that the uncertainties are maintained within a bounded region with minimal number of sampling times.

Abstract: A system for optimizing a stimulation operation includes an interface to equipment and sensors for performing the stimulation operation. The interface supplies control signals to the equipment and obtains measurement signals from the sensors. The system further includes a short-term optimizer that derives a current job state based at least in part on the measurement signals, and that further adjusts the control signals to optimize a short-term cost function. The short-term cost function includes a difference between the current job state and a desired job state derived from optimized values of a set of decision variables. The system further includes a long-term optimizer module that determines the optimized values based on a long-term cost function, the long-term cost function accounting for at least a long-term reward and a final state cost.
