Drill Pipe Failure Analysis
1. Following the (fast approaching) energy crisis, what is the rate of increase in the number of deep wells (say, a well drilled, at least below 15,000 ft for the purpose of exploring for and producing of oil and/or gas); and what is the respective yearly average depth of these wells (before and after Paris Agreement, 12Dec2015) in the context of statistical trends in the drilling of oil and gas wells?
2. Do we still have a relatively good shallow prospects to be drilled?
3. As on date, what would be the percentage of the total budget used in planning for the drilling of a deep well to that for the building of a plant?
4. What is the common budget for the ultra-deep wells, as on date?
5. How exactly is a good workable drilling plan developed?
6. Is there an easy way to figure out, the way the drill pipe gets attacked by corrosion and erosion resulting from the complex alternating loads acting on the drill pipe, including tension, compression, torsion, bending and vibration (in the context of investigating the failure of drill pipe, associated with oil and gas fields)?
7. Can failure of a drill pipe occur at any instances, apart from, @ joint threads; internal surface defects; corrosion pits; and thickened transition areas?
8. Are the failures of drill pipe, remain only associated with, perforation, cracking and fracture?
9. Whether, the predominant failures of drill pipes, remain associated with fatigue or fatigue-induced mechanical defects?
10. Can we expect plastic deformation in the absence of over-load, associated with the ductile fracture of drill pipe?
11. If the location and time of drill pipe failures remain random and if such drill pipe failures have multiple causes and origins, then, how precisely, will be able to assess the failure patterns involving stress concentration, strength reduction, crack initiation, crack propagation through wall thickness, drill pipe perforation and fracture?
Particularly, how about the assessment of ‘crack initiation mechanism’ (friction heat, mechanical damage & corrosion pits) and crack expansion mechanisms (fatigue cracking, corrosion cracking & sulfide stress corrosion)?
12. Is there any other sensitive/critical factor towards failure analysis of drill pipe, apart from material performance, failure characteristics, corrosion characteristics and stress analysis?
The development of a good and workable drilling plan involves a comprehensive process that integrates various technical, economic, and environmental considerations. Here are key steps in developing a drilling plan:
1. Geological and Geophysical Analysis:
- Conduct a thorough analysis of geological and geophysical data to understand the subsurface conditions, identify potential reservoirs, and assess the overall geologic setting.
2. Reservoir Engineering:
- Utilize reservoir engineering techniques to estimate reservoir parameters such as porosity, permeability, and fluid properties. This information is crucial for optimizing well placement and designing an effective drilling strategy.
3. Drilling Risk Assessment:
- Evaluate drilling risks, including potential challenges such as high-pressure zones, wellbore stability issues, and geological uncertainties. This helps in developing contingency plans to mitigate risks during drilling operations.
4. Well Design and Engineering:
- Develop a well design that considers the target depth, drilling fluid properties, and the type of drilling equipment to be used. Engineering aspects like casing design, cementing plans, and well trajectory are critical components.
5. Environmental Impact Assessment:
- Assess the environmental impact of drilling activities, considering factors like water usage, waste management, and adherence to regulatory requirements. Develop plans to minimize environmental impact and ensure compliance.
6. Cost Estimation and Economic Analysis:
- Estimate the overall cost of the drilling project, including drilling equipment, personnel, and operational expenses. Conduct an economic analysis to evaluate the project's financial viability.
7. Health, Safety, and Environmental (HSE) Considerations:
- Integrate health, safety, and environmental considerations into the drilling plan to ensure the well-being of personnel and minimize the impact on the surrounding environment.
8. Regulatory Compliance:
- Ensure compliance with local and international regulations governing drilling activities. Obtain necessary permits and approvals before commencing drilling operations.
9. Project Management and Timelines:
- Develop a project management plan with clear timelines for each phase of the drilling project. This includes drilling, testing, completion, and production phases.
10. Continuous Monitoring and Optimization:
- Implement a monitoring system to track drilling progress and adjust the plan as needed. Continuous optimization based on real-time data helps improve efficiency and mitigate unforeseen challenges.
The success of a drilling plan relies on the collaborative efforts of geologists, engineers, environmental experts, and project managers to address the multidisciplinary aspects involved in drilling operations."
