Ecuador completions use ICDs to control early water breakthrough, allow uniform drainage

摘要

PETROAMAZONAS IS making the most of its horizontal wells in Ecuador's Amazon jungle by completing these wells using inflow control devices (ICDs). Awareness of the shortcomings of horizontal wells prompted the company, with the assistance of Schlumberger, to address the issues of early water breakthrough and heterogeneity and permeability contrasts up-front. The result has been higher performance compared with a conventional completion, delay of potential early water breakthrough, no sand production and the efficient restriction of high mobile phases.
