Well Intervention, Workover & Rigless Operations Training Course

Course Overview

Learning Objectives

• Analyze the role of well intervention and workover in managing mature fields, production decline, and well integrity on Day 1.
• Identify the common reasons for well interventions, including production decline, water and gas breakthrough, sand production, scale, wax, asphaltenes, and mechanical failures.
• Apply well performance diagnostics, including production data analysis, well tests, production logging, and nodal analysis, to select intervention candidates.
• Apply well integrity principles, including well barrier philosophy, barrier verification, and annular pressure management, to intervention planning.
• Compare rigless intervention methods, including slickline, electric line, coiled tubing, and hydraulic workover and snubbing units, with rig-based workovers.
• Plan logging, perforating, and re-perforating operations to evaluate and restore well productivity.
• Evaluate stimulation, scale and deposit removal, and sand control interventions and their selection criteria.
• Plan zonal isolation and water and gas shut-off interventions using plugs, packers, cement squeezes, and chemical treatments.
• Plan artificial lift interventions, including gas lift valve change-outs and electric submersible pump replacements, and fishing and milling operations.
• Select appropriate well kill methods and pressure control equipment for different intervention operations.
• Develop intervention programs, risk assessments, and simultaneous operations plans that protect people, the environment, and well integrity.
• Evaluate intervention economics and conduct post-job evaluations to capture lessons learned and improve future interventions by the end of Day 5.
