摘要： A system includes a high-pressure static mixer. The system also includes a clean fluid system that provides clean fluid to the first high-pressure static mixer at a first fluid velocity and a proppant fluid system that provides a proppant concentrate to the first high-pressure static mixer at a second fluid velocity. Additionally, the system includes a wellhead in fluid communication with the first high-pressure static mixer. The wellhead receives a mixed fluid including the clean fluid and the proppant concentrate from the first high-pressure static mixer.

摘要： Selecting a fracing-plan-to-apply to optimize a complexity index includes identifying a set of controllable input variables that defines a fracing plan. Initial values for the set of controllable input variables are defined. The initial values of the set of controllable input variables are processed to produce an initial stimulated geometry. A complexity estimator is applied to the initial stimulated geometry to produce an initial complexity index, which is evaluated to identify at least one variation from the initial values, which is processed to produce a variation stimulated geometry for each of the at least one variation from the initial values. The complexity estimator is applied to the at least one variation stimulated geometry to produce a variation complexity index for each of the at least one variation from the initial values. The fracing-plan-to-apply is selected from among the initial values and the at least one variation from the initial values.

摘要： Fracturing operations that include fluid diversion cycles may include real-time, continuous-flow pressure diagnostics to analyze and design the fluid diversion cycles of fracturing operations. The real-time, continuous-flow pressure diagnostics are injection rate step cycles that may include open low injection rate step cycles, propped low injection rate step cycles, diverted low injection rate cycles, and high injection rate cycles.

摘要： A method comprising: introducing a first fluid into a wellbore above a fracture gradient of a subterranean formation penetrated by the wellbore to create a first plurality of fractures within a first portion of the subterranean formation; introducing a second fluid comprising at least one acid component into the wellbore above the fracture gradient of the subterranean formation penetrated by the wellbore to create a second plurality of fractures within a second portion of the subterranean formation; allowing the second fluid to enter at least one natural fracture in the first or second portion of the subterranean formation allowing the acid component to dissolve at least a portion of the subterranean formation to form one or more induced fractures in fluidic communication with the natural fracture, at least some of the first plurality of fractures, and at least some of the second plurality of fractures.
