Crossflow Index

Crossflow Index (CI) quntifies the ability of a well to crossflow from one zone to another. CI shares the same units as Injectivity Index (II) or Productivity index (PI),[stb/d/psi]. The equation for CI is as flows: CI = (PI*II)/(PI+II)

This equation is derived from the equation for electrical resistors in series. Resistance is the inverse of PI and II. The electrical equation V=IR is eqivalent to dP=Q/PI.

The concept of Crossflow Index as well as it's derivation were originated by Jules Guste.

Crossflow Index may also be known as Dumpfloodivity.
