Top 10 Questions for Casing Running Machine Tender Interview

1. Explain the different types of casing running machines and their applications?

• Conventional Casing Running Machine: Used to run casing in vertical wells, features a rotating table, and slips to hold the casing in place
• Mechanized Casing Running Machine: Automated system that handles casing handling, stabbing, and running operations, increasing efficiency
• Casing Pusher: Pushes casing into the wellbore using hydraulic pressure, suitable for horizontal wells where conventional methods are challenging
• Continuous Casing Running Machine: Continuously feeds casing into the wellbore without stopping, minimizing connection time and Risiken

2. Describe the operational procedure for running casing using a casing running machine?

General Procedure

• Prepare the machine and ensure it’s properly aligned with the wellhead
• Install the casing slips and ensure they are securely tightened
• Stab the casing into the wellhead and connect it to the machine
• Initiate casing running by controlling the speed and torque of the machine
• Monitor the operation and make adjustments as needed to prevent bending or damage to the casing

Specific Considerations

• Adjusting running speed according to casing size, well depth, and formation conditions
• Monitoring hydraulic pressure to ensure proper lubrication and prevent stuck casing
• Maintaining proper torque to prevent thread damage or casing overtightening

3. What are the safety precautions you take when operating a casing running machine?

• Wear appropriate safety gear (hard hat, gloves, etc.)
• Ensure proper machine setup and alignment before operation
• Keep hands and body away from moving parts and pinch points
• Maintain a safe distance from the wellhead and casing
• Communicate clearly with colleagues and follow hand signals
• Monitor operational parameters (pressure, torque, speed) and adjust as needed
• Immediately stop operation if any unsafe condition or equipment malfunction is detected

4. How do you troubleshoot common problems encountered while running casing?

• Stuck Casing: Check lubrication, apply pressure, or use mechanical tools (e.g., jars, slips)
• Excessive Torque: Reduce running speed, check thread condition, or adjust machine settings
• Hydraulic Leaks: Locate and tighten fittings, check hoses, or replace seals
• Machine Malfunctions: Troubleshoot electrical or mechanical issues, consult manufacturer’s guidelines
• Casing Damage: Inspect casing for bends, breaks, or other defects, consult with drilling team for corrective actions

5. What are the essential maintenance tasks to ensure the optimal performance of a casing running machine?

• Regular lubrication of moving parts (e.g., gears, bearings, chains)
• Inspection and tightening of bolts and connections
• Testing of hydraulic systems and pressure relief valves
• Electrical inspections and grounding checks
• Cleaning and greasing of exposed surfaces to prevent corrosion
• Following manufacturer’s recommended maintenance schedule

6. How do you coordinate with the drilling team to ensure a successful casing running operation?

• Review casing running plan and discuss specific requirements
• Communicate casing depth, connection points, and running speed
• Collaborate on troubleshooting and contingency plans in case of unexpected issues
• Provide updates on casing running progress and any deviations from the plan
• Listen to the drilling team’s feedback and adjust operations accordingly

7. What are the key performance indicators (KPIs) you monitor to evaluate the efficiency of casing running operations?

• Casing running time (total and per joint)
• Connection time (make up and break out)
• Number of stuck casing incidents
• Casing integrity (damage or leaks)
• Machine uptime and maintenance costs

8. How do you keep up with the latest advancements and best practices in casing running technology?

• Attend industry conferences and workshops
• Review technical publications and articles
• Consult with equipment manufacturers and service providers
• Seek feedback and exchange knowledge with experienced colleagues
• Stay informed about new technologies and their potential applications

9. What is your understanding of the role of torque monitoring during casing running?

• Monitoring torque helps ensure proper thread engagement and prevents overtightening or undertightening
• Excessive torque can lead to thread damage or casing deformation
• Insufficient torque can result in loose connections or leaks
• By monitoring torque, the operator can adjust running speed or torque settings to achieve optimal thread makeup

10. Explain the importance of proper handling and storage of casing to prevent damage or premature wear.

• Proper handling techniques minimize scratches, dents, or bends that could affect casing integrity
• Storage in designated areas prevents exposure to weather elements (e.g., rust, corrosion)
• Using racks or cradles supports casing and prevents deformation
• Protecting casing ends with caps prevents damage or contamination
• Following manufacturer’s guidelines ensures longevity and optimal performance of casing
