ESCOBAR, Freddy Humberto; PALOMINO, Angela María  e  GHISAYS-RUIZ, Alfredo. An approximation of behind-casing hydraulic conductivity between layers from transient pressure analysis. Dyna rev.fac.nac.minas [online]. 2019, vol.86, n.210, pp.108-114. ISSN 0012-7353.  https://doi.org/10.15446/dyna.v86n210.76739.

Flow behind the casing has normally been identified and quantified using production logging tools. Very few applications of pressure transient analysis, which is much cheaper, have been devoted to determining compromised cemented zones. In this work, a methodology for a well test interpretation for determining conductivity behind the casing is developed. It provided good results with synthetic examples.
