Smart Completion System Single Trip Drilling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for completing subterranean wells require separate trips for drilling and completing the well, increasing the risk of a stuck pipe due to multiple tubular member insertions and lack of resistance to drilling torque, compression, and pressure.
Innovation Solution
A smart completion system that integrates a bottom hole assembly with components capable of withstanding torque, compression, and pressure, allowing a single trip to drill and complete the well, including a liner and differential valve tool for cementing, and a whipstock for deviated wellbore drilling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate trips are used for drilling and completing the well, then the well can be completed with proper liner and completion assembly, but the risk of stuck pipe increases and operational complexity increases
Solution Approach 1:
The patent combines the drilling operation and completion operation into a single trip. The drill string is configured to include both drilling components (drill bit) and completion components (liner, completion assembly) integrated together, allowing both functions to be performed in one operational sequence without requiring separate trips into the well.
Solution Approach 2:
The drill string is designed as a multi-functional tool that performs both drilling and completion functions. The integration of the liner and completion assembly onto the drill string enables it to serve dual purposes: creating the wellbore and then providing the completion structure, thereby reducing operational complexity and stuck pipe risk.
2Strength
If the smart completion components are designed to withstand drilling forces, then they can survive the drilling process, but the device complexity increases
Solution Approach 1:
The smart completion components are constructed using composite material structures that combine materials with different properties to achieve high strength-to-weight ratios. This allows the components to withstand the extreme forces generated during drilling (torque, compression, tension) while maintaining a manageable structural design that can be integrated into the drill string.
Solution Approach 2:
The design of the smart completion components incorporates variable geometric parameters and structural configurations that optimize their mechanical properties. By adjusting parameters such as wall thickness, cross-sectional geometry, and material distribution, the components achieve the necessary strength to survive drilling forces without requiring excessive complexity in their overall structure.

AI summary
A method for completing a subterranean well with a smart completion system includes drilling the subterranean well to a first depth with a first drill string having a first drill string tubular and a first bottom hole assembly with a first drill bit. The first drill string is retrieved and a casing is cemented within the first depth. The subterranean well is drilled to a second depth with a second drill string having a second drill string tubular, a liner, and a second bottom hole assembly that includes a smart completion and a second drill bit. The liner is set within the casing and the second drill string tubular is retrieved, retaining the liner and the second bottom hole assembly within the subterranean well. Fluid from the subterranean well is produced through the second bottom hole assembly.
