Abstract: In accordance with presently disclosed embodiments, a hybrid drive system that uses multiple sources of mechanical energy to drive a pump is provided. The hybrid drive system may include a first mover for generating first mechanical energy, a pump, a drivetrain for providing first mechanical energy from the first mover to the pump, and a second mover within the drivetrain to generate and provide second mechanical energy to the pump. The multiple sources of mechanical energy may provide flexibility with respect to system design and allow for alternative sources of fuel and energy to be used to drive pumping systems. This may reduce the total diesel fuel consumption necessary to perform a well stimulation operation as well as provide for configurations in which diesel engines may be excluded from the pumping process in favor of alternative energy sources that typically do not have sufficient torque capacity to power a pump.

Abstract: In accordance with presently disclosed embodiments, a method and computer system for scheduling and timing the movements of a plurality of bulk material containers into position to output bulk materials directly into a blender inlet are provided. The disclosed sequencing techniques may include planning a sequence and timing of bulk material container movement and usage during operations at a job site. The planned sequence and timing of these operations may be developed to reliably provide the correct material type and quantity to a blender at a desired time to meet a treatment design profile. In addition, the disclosed system and method may monitor the real time operations on location to track how closely the movements of bulk material containers conform to the schedule developed for the well treatment.

Abstract: Methods and apparatus are disclosed for mixing proppant and other solids with one or more fracturing fluids to form a fracturing slurry, and for delivering the fracturing slurry to a wellbore. In the example systems as described herein, the proppant is mixed with the fracturing fluids through an assembly that limits the number of pumps that are required to move the relatively abrasive proppant]containing fluids. Additionally, in the example systems, the proppant is mixed within enclosed structures, thereby minimizing the escape of dust and other particulates into the surrounding atmosphere and onto the equipment at the well site.

Abstract: In accordance with presently disclosed embodiments, systems and methods for efficiently managing bulk material are provided. The disclosure is directed to systems and methods for efficiently combining additives into bulk material being transferred about a job site. The systems may include a support structure used to receive one or more portable containers of bulk material, and a mulling device disposed beneath the support structure to provide bulk material treatment capabilities. Specifically, the mulling device may facilitate mixing of coatings or other additives with bulk material that is released from the portable containers, as well as transfer of the mixture to an outlet location.

Abstract: A job plan may be developed far in advance of actual execution of any one or more specified well servicing operations. To account for all the factors, parameters or conditions that occur at an actual well site a revised job plan may be generated that accounts for the actual site equipment available, environmental factors, one or more costs, available power source, optimal operation of equipment and any other factors. Any one or more of the factors may be weighted according to a particular physical location or other factors of the job plan. Correlating the collected, known, and actual information about equipment and a physical location allows for the generation of an optimized revised job plan that provides better utilization of equipment, including power sources, and control of costs.

Abstract: In accordance with embodiments of the present disclosure, systems and methods for reconfiguring a vertical storage silo used to store proppant (or other dry material) so that the storage silo may be used in a desired orientation at a worksite are provided. The disclosed embodiments may include a vertical storage silo assembly used to selectively deliver material from one of two different outlet orientations. The silo assembly may offer two distinct orientations for an outlet chute relative to a transportation chassis used to transport and erect the vertical silo. The silo assembly may include a storage silo and a base for supporting the storage silo in a vertical orientation, the storage silo being removably coupled to the base. The storage silo may also be rotatable relative to the base to transition or reposition the outlet chute between a right-hand orientation and a left-hand orientation relative to the base.

Abstract: A damper is provided for a well system. The well system utilizes a pressure pulse generator in the wellbore to generate a pressure pulse through fluid, such as treatment fluid, in the wellbore. The damper is received in the wellbore to damp transmission of the pressure pulse through the fluid while also allowing fluid to flow through the wellbore between a terranean surface and a location adjacent the pressure pulse generator. In certain instances, the damper allows flow of fluid past the damper while damping transmission of the pressure pulse through the fluid.

Abstract: A system is configured to fracture a formation surrounding a subterranean wellbore. In one example, the system includes a tool string configured to be deployed in the wellbore, and an acoustic pulse generator connected to the tool string and configured to transmit acoustic pressure pulses into the formation. The acoustic pulse generator is configured to generate acoustic pressure pulses with a magnitude of at least 1000 pounds per square inch.

Abstract: An apparatus for laser drilling including a laser beam emitter disposed within a housing having at least one laser beam outlet and at least one purge fluid outlet. At least one actuated nozzle is disposed within the housing for providing a purge fluid through the purge fluid outlet and having functional control for synchronized programmable activation patterns. Laser beam control is provided for directing a laser beam over a target surface.

Abstract: A method for wellbore perforation in which a section of the wellbore to be perforated is isolated and purged of wellbore fluid to provide a clear path for laser beam transmittal. A laser beam emitter in the purged wellbore section transmits a laser beam pulse from the laser beam emitter to a target area of a sidewall and formation lithology of the purged wellbore section, thereby altering a mechanical property of a material of the sidewall and formation lithology and producing material debris. A liquid jet pulse of a liquid is transmitted immediately following termination of the laser beam pulse to the target area, thereby removing the material debris from the target area. This cycle is then repeated until the desired perforation depth has been achieved.

Abstract: Methods, systems, and devices related to downhole wellbore operations such as drilling and completing wells in an earth formation that include a laser device. The method includes lasing a rock and detecting an optical response of the lased rock. It can be determined from the optical response whether the lased rock is responding as specified (e.g. spalling, melting, etc.) If the lased rock is not responding as specified, one or more laser parameters are adjusted to achieve the specified response. Spalling is determined by the detection of sparks, or other light that erratically changes in intensity over time, by an optical detector. The detection of steady light may indicate other types of rock removal mechanisms, such as melt or dissociation.
