... of the start and end time of FDI during each frac stage, its magnitude, and duration. Another important parameter is observing smoothness of FDI variations with time. The paper offers specific recommendations for additional measurement and computational steps that can be used for determination of the volume...

... intervention. However, traditional ball-activated frac sleeves have graduated ball seat sizes for each additional zone, and therefore, each ball seat creates its own backpressure within the system. With the number of frac stages increasing, the ball seat sizes become smaller, leading to an increase...
