... of these gravel packs are pumped with no positive pump pressure as the positive u-tube pressure of the additional hydrostatic weight of the slurry in the work string is higher than the overall friction pressure in the system. This effect can have a significant impact on the job execution in several ways...

... pumping pressure due to internal friction which increases fuel consumption and emissions. Smaller tubing and higher internal friction can limit the annular velocity that can be achieved, leading to less effective hole cleaning. In many cases friction reducers are added to the circulating system to reduce...

Added uncertainties including string friction, debris buildup, and depth of OCD will result in variability in forces required to initiate shift ( Kenison et al, 2012 ). As a result, any added weight observed at the depth of the OCD is assumed...
