Cellar Spanning Platform for Drilling Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional well site platforms for hydrocarbon extraction face limitations due to limited access and the need to work adjacent to open pits or cellars, which hinder efficient interaction with well heads, particularly in Cellar Tech containment cellars with inwardly facing lips.
Innovation Solution
A surface rig platform system comprising a central platform, side platforms, wheel risers, and box beams that span across the cellar, allowing vehicles to access well heads by crossing the cellar, with perforated plates for fluid and gas migration and adjustable wheel risers for vehicle movement, enabling improved access and operation in Cellar Tech containment cellars.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional well sites are located flush with or above ground, then accessibility to well heads is improved, but safety and containment are worsened
Solution Approach 1:
The platform extends vertically across the cellar opening, creating a three-dimensional structure that allows vehicles to access well heads from above while maintaining containment. This vertical dimension resolves the contradiction by enabling both accessibility (vehicles can drive onto the platform) and safety (well heads remain contained within the cellar structure).
Solution Approach 2:
The platform acts as an intermediary structure between the surface and the cellar. It provides a stable working surface that mediates between the need for vehicle access and the requirement for containment, allowing operations to proceed without direct exposure to the open cellar pit.
2Reliability
If well heads are located in open pits or cellars, then safety and containment are improved, but access and operational efficiency are worsened
Solution Approach 1:
By creating a vertical platform structure that spans the cellar opening, the invention adds a vertical dimension to the operational space. This allows multiple well heads to be accessed simultaneously from different positions on the platform, improving operational efficiency while maintaining the safety benefits of contained cellar locations.
Solution Approach 2:
The platform is divided into multiple levels and sections that can be configured to accommodate different well head positions. This segmentation allows efficient access to multiple well heads without requiring a single large open area, thereby maintaining containment while improving productivity.
3Reliability
If Cellar Tech containment cellars with inwardly facing lips are used, then containment and safety are improved, but vehicle access and positioning are worsened
Solution Approach 1:
The platform creates a vertical working surface that extends over the cellar opening, allowing vehicles to position themselves on the platform rather than attempting to navigate the inwardly facing lips at ground level. This vertical dimension bypasses the access difficulty created by the lip structure while maintaining containment.
Solution Approach 2:
The platform serves as an intermediary working surface between the vehicle and the well head. Instead of vehicles directly interacting with the challenging lip structure, they operate on the stable platform surface, which mediates the interaction and simplifies positioning while maintaining safety containment.

AI summary
A system and method for enabling drilling equipment to access and work with well heads located in a cellar type arrangement. Modules are combined together with wheel risers to form various shaped platforms for spanning across the roof of cellars for hydrocarbon extraction. The various shaped platforms provide support adjacent the well head for work over rigs and surface rigs to drive adjacent the well heads located in the cellar.
