Drilling engineering services were used to reduce well costs and improve drilling performance in Webb County by applying statistical modeling and optimizing drilling practices. By evaluating bit selection, drilling fluids, and steerable systems, IPT identified lower-risk, cost-effective approaches. The result was improved cycle time consistency, reduced lost time incidents, and overall lower cost per well.
The Challenge
- High drilling costs across unconventional wells in the Eagle Ford
- Frequent lost time incidents impacting overall cycle time
- Uncertainty around optimal rig types, bit selection, and drilling fluid practices
- High failure rates associated with certain steerable systems
- Inefficient drilling practices leading to increased operational risk
Our Approach
Data-Driven Performance Analysis
Applied statistical modeling across multiple wells to evaluate drilling performance drivers, including lost time, rig types, and operational practices.
Lessons Learned Integration
Leveraged insights from over 6,000 wells and 400 disposal wells to identify proven strategies for cost reduction and efficiency improvement.
Bit Selection Optimization
Analyzed and selected drill bits based on formation performance and operational reliability to improve drilling consistency.
Drilling Fluid Evaluation
Reviewed fluid systems and eliminated unnecessary practices such as weighted sweeps that added cost without measurable benefit.
Steerable System Comparison
Evaluated rotary steerable systems versus motor steerable systems to balance penetration rate with reliability and failure risk.
These improvements were implemented through a structured Drilling engineering workflow supported by broader Reservoir engineering insights and real-world field data.
Results
- Reduced overall drilling costs per well and across the program
- Lower lost time incidents, improving average well cycle times
- Decreased BHA failure rates, minimizing costly fishing operations
- Improved risk-adjusted performance despite slightly lower penetration rates
- Optimized drilling strategy using two BHA configurations:
- Drill-out BHA designed for rapid drilling to KOP
- Curve and lateral BHA designed for reliability and consistency
- Motor steerable systems delivered lower cost outcomes despite being slightly slower
Why It Matters
Small inefficiencies in drilling operations compound quickly across multi-well programs. By focusing on reliability, risk reduction, and data-backed decision making, operators can:
- Lower total cost per well without sacrificing performance
- Reduce operational uncertainty and non-productive time
- Improve consistency across drilling campaigns
- Make better trade-offs between speed and reliability
This case demonstrates how integrated Project management and field execution combined with technical expertise can drive measurable financial outcomes.
Drilling engineering services involve the design, optimization, and execution of drilling programs. These services focus on improving efficiency, reducing risk, and lowering costs through technical analysis and field experience.
They reduce costs by optimizing drilling parameters, selecting the right equipment, and minimizing failure risks. This includes improving bit selection, refining drilling fluid systems, and choosing the most reliable steerable technologies.
Motor steerable systems may have lower penetration rates, but they typically offer higher reliability and lower failure rates. This reduces non-productive time and overall well costs.
Drilling performance optimization uses data analysis and operational insights to improve efficiency. It focuses on reducing lost time, improving cycle time, and selecting the most effective drilling methods.
Data is critical. Statistical modeling and lessons learned from previous wells allow operators to make informed decisions that reduce risk and improve outcomes.
Yes. These drilling efficiency improvement strategies are applicable across unconventional plays and other subsurface environments where cost and performance optimization are critical.
