Whipstock Packer Assembly With Remote Downhole Activation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional whipstock assemblies for multilateral sidetracks require tedious handling on the rig floor and involve mechanical or hydraulic connections, posing risks and inefficiencies in setting packer assemblies.
Innovation Solution
A downhole tool incorporating a Downhole Power Unit (DPU) that remotely activates the packer assembly, eliminating the need for hydraulic connections and mechanical manipulation, allowing for orientation and setting of the whipstock assembly without premature packer assembly activation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional whipstock assemblies are used with mechanical or hydraulic connections, then the packer assembly can be set, but rig floor handling risks increase and operational efficiency decreases
Solution Approach 1:
The patent replaces mechanical and hydraulic connection systems with a downhole power unit that uses electrical or electronic signaling to activate the packer assembly. This substitution eliminates the need for complex mechanical manipulations and hydraulic connections on the rig floor, thereby reducing handling risks while maintaining operational efficiency through automated downhole activation.
Solution Approach 2:
The downhole power unit acts as an intermediary between the surface control system and the packer assembly. It receives activation signals from the surface and translates them into mechanical action to set the packer, eliminating the need for direct mechanical or hydraulic connections through the whipstock assembly and reducing rig floor handling complexity.
2Ease of operation
If hydraulic connections are used to set the packer assembly, then the packer can be activated, but the process becomes more complex and time-consuming
Solution Approach 1:
The patent replaces the hydraulic connection system with an electrical/electronic activation mechanism integrated into the downhole power unit. This substitution simplifies the activation process by using electrical signals instead of complex hydraulic routing, reducing device complexity while improving ease of operation through more straightforward control mechanisms.
3Reliability
If mechanical manipulation is required to set the packer assembly, then the packer can be deployed, but handling risks and time requirements increase
Solution Approach 1:
The patent replaces manual mechanical manipulation with automated downhole power unit activation. The mechanical action to set the packer is triggered automatically by electrical or electronic signals from the surface, eliminating the need for time-consuming and risky manual handling operations while maintaining reliable packer deployment.
Solution Approach 2:
The downhole power unit is pre-positioned and prepared within the whipstock assembly before reaching the target location. Upon receiving activation signals, it immediately executes the packer setting action without requiring time-consuming mechanical manipulation, thereby reducing handling time and risks while ensuring reliable deployment.
