Well intervention
Well intervention is essential for optimizing and maintaining the performance of oil, gas, and geothermal wells. These operations involve a range of techniques and technologies designed to enhance well productivity, address issues, and manage well integrity without requiring a full workover. Our well intervention services utilize advanced equipment and methodologies to ensure effective and efficient interventions.
Key Well Intervention Techniques:
Coiled Tubing Operations: Coiled tubing operations involve the use of a continuous, flexible metal pipe that can be spooled onto a reel and deployed into the wellbore. This method allows for a variety of well intervention activities, including:
- Well Cleanouts: Removal of debris, scale, and sand to restore well productivity and improve flow rates.
- Nitrogen Lifting: Injection of nitrogen gas to enhance fluid lifting and increase production rates.
- Concentric Coiled Tubing: Utilizes dual tubing for simultaneous fluid injection and production, providing enhanced performance in complex well conditions.
Wireline Operations: Wireline operations use a cable to perform various downhole tasks, including:
- Formation Evaluation Logging: Measures downhole properties like resistivity, porosity, and density to assess reservoir characteristics.
- Production Logging: Monitors fluid flow profiles, temperatures, and pressures to optimize well performance and diagnose issues.
- Perforating: Deploys shaped charges to create openings in the casing and formation, initiating or enhancing production.
- Sampling: Collects fluid samples for analysis, aiding in reservoir characterization and production optimization.
- Well Intervention: Involves mechanical services such as setting or retrieving downhole equipment, cleanouts, and scale removal.
Slickline Operations: Slickline operations use a single, solid wire to perform mechanical tasks without electrical power:
- Setting and Retrieving Tools: Deploys and retrieves tools like plugs, valves, and gauges for well testing and production optimization.
- Well Intervention: Handles well cleanouts, scale removal, and other remedial treatments.
- Plug and Abandonment: Sets plugs to isolate zones or permanently seal wells, ensuring safety and regulatory compliance.
Surface Well Testing: Surface well testing evaluates well productivity and performance by measuring flow rates, pressures, and fluid properties at the surface. The process includes:
- Preparation and Planning: Reviewing well data and selecting appropriate equipment.
- Equipment Setup: Mobilizing and installing flowlines, separators, chokes, and gauges.
- Flowback: Removing completion fluids and debris from the wellbore.
- Well Testing: Measuring and recording production parameters.
- Data Analysis: Evaluating well performance and reservoir characteristics.
- Reporting: Providing comprehensive reports with analysis and recommendations for future actions.
Benefits of Well Intervention:
- Enhanced Production: Improves well output and efficiency through targeted interventions.
- Reduced Downtime: Allows for quick, effective solutions without the need for a full workover.
- Cost-Effective: Minimizes operational costs while maximizing well performance.
- Versatility: Accommodates a wide range of tasks and well conditions, from routine maintenance to complex interventions.
