The split flow pumping system configuration may comprise one or more controllers for controlling the one or more blenders, the one or more boost pumps, the pumping system comprising one or more pumps, the component storage system, and the fluid storage system. The system may comprise one or more sensors for collecting data corresponding to the one or more pressures, flow rates, injection rates, compositions, temperatures, and densities of at least one of the first composition and the second composition, wherein the controller controls the one or more pressures, flow rates, injection rates, compositions, temperatures, and densities of at least one of the first composition and the second composition based, at least in part, on the data.

摘要： To improve or optimize a wellbore treatment operation, a target net treating pressure may be determined and the constant net treating pressure maintained to effectively enhance formation breakdown and fracture complexity as well as provide a reduction in wear and tear of equipment and completion time. The target net treating pressure may be based on one or more treatment parameters and these parameters may be adjusted during the wellbore treatment operation to maintain a constant net treating pressure at or about the target net treating pressure. The injection rate or pressure of a treatment fluid may be adjusted to maintain the constant net treating pressure. Measurements associated with the wellbore treatment operation may be compared to an operational constraint and adjustments to the wellbore treatment operation may be made based on the comparison. The wellbore treatment operation may be terminated based on a parameter falling below or exceeding a threshold.

摘要： Methods and systems wherein a first setpoint is used with a controller to translate the setpoint into a desired flow rate from a pump and used to determining an optimized command signal associated with the first setpoint with a process control system, the process control system configured to incorporate at least a first setpoint and a measurement signal to produce the optimized command signal. The optimized command signal is then stored in a memory of the computer. When the first setpoint is again desired, the optimized command signal associated with the first setpoint is read from the memory and transmitted to the pump.

摘要： Fracturing systems and methods for increasing the conductivity of a flow path between a reservoir formation and a wellbore are presented that include varying a proppant concentration of a fracturing fluid in response to a measured characteristic from the wellbore during the fracturing process. During the injection of proppant pulses into the wellbore, one or more of a pulse length, pulse height, pulse shape, or duty cycle of the proppant concentration is varied. Other systems and methods are disclosed.

摘要： A pumping system and method for blending hydraulic fracturing fluids includes a liquid additive holding tank having an outlet at a bottom of the holding tank, a first sensor at a first location in the holding tank adjacent a lower portion of the holding tank, and a second sensor at a second location in the holding tank above the first location. The pumping system further includes a liquid additive pump to deliver fluid gravity fed from the outlet of the holding tank, a chemical transfer pump to pump fluid into the holding tank in response to receiving a first signal that a fluid level of the holding tank is below the first sensor and cease to pump fluid into the holding tank in response to receiving a second signal from the second sensor indicating the fluid level is above the second sensor.

摘要： Methods and systems for controlling proppant concentration in a hydraulic fracturing slurry include measuring volumetric flow rates of fracturing fluid input to a blender and hydraulic fracturing slurry output from the blender, using these measured values to calculate a volumetric flow rate of proppant input, a slurry density and/or a slurry volume fraction, adjusting first and second valves to control rates of fluid and proppant delivery to the blender and re-measuring the volumetric flow rates and recalculating until target values of volumetric flow rate of proppant input, slurry density and/or slurry volume fraction are achieved.

摘要： Described herein are systems, apparatuses, methods and computer-readable media that monitor and evaluate the density of a slurry of materials provided to a wellbore. Such systems and methods may be used when a volume of solids used in a hydraulic fracturing process is mixed with a volume of fluid when the slurry of materials is formed according to a hydraulic fracturing rule. This slurry may then be provided to the wellbore such that a hydraulic fracturing process may be completed. Here the solids may include a specific type of sand, a proppant material, or other material. Fluids used to make the slurry may include water, chemicals, or other liquids. A density of the slurry may be identified based on measurements that identify a mass of solids and volume of fluid that are provided to form the slurry.
