Abstract
This article provides a summary and assessment of well intervention activities, including perforation (add-perf/re-perf), acid treatment (acidizing), water/gas shut-off (WSO/GSO), hydraulic fracturing (HF), and electric submersible pump installation (ESP) at oil and gas production projects that the Petrovietnam Exploration and Production Corporation (PVEP) has participated in investment, operation, and optimization during the period of 2017 - 2021. Based on this, the effectiveness of well interventions in increasing production and reservoir recovery is evaluated. Additionally, the article analyzes lessons learned and proposes directions for optimizing well interventions for the next phase.
