Performance study: water coning in Amassak field - Ain Aminas.

Abstract

Water coning is one of the major problems during oil production, which is the movement of the oil-water interface towards the well boundaries forming a cone. By choosing five producing wells AMA73, AMA75, AMA69, HBDA1 and HBDA6, this study analyses the performance of the Amassak field to understand and mitigate the effects of this phenomenon. This research aims to display the impacts of water cut on the oil production rates using Prosper software, diagnose the water coning with Chan plot, and evaluate production and mitigation techniques. The results indicate that implementing short-radius wells (HBDA6 water cut reduced from 60.98% to 0%) and maintaining oil production rates near critical thresholds can delay water breakthrough time and minimize the economic impact.
