... Abstract Some measure of completion quality is often used to determine the success of the completion operations performed on petroleum wells. Some of the parameters used to determine the quality of the completion are productivity index (J), skin factor (S), productivity ratio (J actual /J ideal...

... for fracture designs in medium permeability formations. These equations are critical to optimize fracture designs and are different for primary depletion and formations under waterflooding processes. This paper presents two new models to calculate the dimensionless productivity index, J D , of finite...

...]. This field has produced oil with an increasing water cut for 25 years. It is swept; its average water cut now amounts to 98 %. Areally, the reservoir is made up of two distinct but communicating formations; i.e., a highly fractured dolomite--productivity index, J = 1 m3/(kPa.d) [50 bbl/(psi-D)]--and almost...
