Understanding the Basics of Well Intervention

In the oil and gas industry, well intervention operations are essential for maintaining and optimizing production from oil and gas wells.

DefinitionWell intervention refers to activities conducted on oil or gas wells to increase or restore production, improve well integrity, or perform maintenance and repair tasks.
Types of Well InterventionWireline Intervention: Uses a cable to deploy tools and equipment into the wellbore for services such as logging, perforating, or setting plugs and packers.
Coiled Tubing Intervention: Involves injecting a continuous length of tubing into the well to perform services like cleanouts, milling, or acidizing.
Snubbing Intervention: Utilizes a hydraulic unit to insert and extract pipe strings under pressure, enabling operations in live wells without shutting in production.
Hydraulic Workover (HWO): Involves rigging up a workover rig to perform more extensive interventions like completions, sidetracking, or wellbore remediation.
BenefitsIncrease Production: Stimulate reservoirs, remove obstructions, or repair damaged equipment to enhance production rates.
Enhance Well Integrity: Address integrity issues, isolate zones, or plug and abandon wells to prevent environmental contamination or wellbore instability.
Perform Maintenance: Conduct routine maintenance tasks, such as cleaning, tubing replacements, or equipment inspections, to ensure optimal well performance.
Improve Reservoir Management: Gather data through logging or testing, install monitoring equipment, or implement reservoir stimulation techniques for enhanced recovery.
