    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: A method for drilling a well. The method may include detecting stick-slip vibrations at a frequency via a downhole sensor. The method may further include determining a reflection coefficient of a drill bit for the frequency based on at least one of a rotational speed of the drill bit or a torque of the drill bit. The method may also include determining a reflection coefficient of a top drive for the frequency based on at least one of a rotational speed of the top drive or a torque produced by the top drive. The method may further include adjusting a control system in electronic communication with the top drive based on the reflection coefficient of the drill bit for the frequency and the reflection coefficient of the top drive for the frequency.

    Abstract: The disclosure provides a solution for monitoring stick-slip vibrations without using any surface torque measurements. Instead, the disclosure provides a method to monitor stick-slip vibrations based on rotational speed. A stick-slip monitor, a top drive controller and a method of operating a drill string are provided herein that use rotational speed for monitoring stick-slip vibrations. In one example, the method of operating a drill string includes: (1) performing a frequency domain analysis of an RPM signal associated with a top drive that is used to rotate a drill string, and (2) determining a presence of torsional oscillations of the drill string based on the frequency domain analysis of the RPM signal.

    Abstract: In some aspects, the present disclosure includes systems and methods for determining and delivering diverting material to dominant fractures in a stage of a subterranean formation. The method includes creating or extending a plurality of fractures in a stage of a subterranean formation; pumping fracturing fluid to the plurality of fractures; identifying dominant fractures among the plurality of fractures; determining a desired amount of diverters to deliver to the dominant fractures; and pumping the determined amount of diverters to the dominant fractures so as to redistribute the flow of fracturing fluid between the plurality of fractures.
