Problem
Conventional cuttings treatment systems for drilling rigs are oversized, cumbersome, and inefficient, obstructing access and space usage, and lack the capability for onsite processing and refinement of drill cuttings.
Innovation Solution
A modular cuttings processing unit that includes a utility interface, a breaker mill module for grinding cuttings into a finer composition, a cuttings tank module for creating a slurry through agitation, and a pump module for pumping the slurry, allowing for onsite processing and minimizing the rig's footprint.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If conventional rock washers are used to collect and transport cuttings, then cuttings can be disposed of, but the equipment becomes oversized and obstructs access and space usage
Solution Approach 1:
The system is divided into separate functional modules: a shale shaker for cuttings separation, a hopper for collection, and a pump for slurry disposal. Each module performs a specific function, allowing the system to be compact while maintaining full cuttings disposal capability. The modular design eliminates the need for a single large conventional rock washer.
2Ease of manufacture
If conventional cuttings treatment systems are used, then cuttings can be managed, but the systems are cumbersome and inefficient
Solution Approach 1:
The system combines cuttings separation, collection, and disposal functions into an integrated modular unit. The shale shaker separates cuttings from drilling fluid, the hopper collects the cuttings, and the pump efficiently transports the slurry. This merged system eliminates the inefficiencies of separate conventional equipment while improving overall processing productivity.
3Area of stationary object
If modular cuttings processing units are used to reduce footprint, then access and space utilization improve, but system complexity increases
Solution Approach 1:
The system is segmented into standardized modular components (shale shaker, hopper, pump assembly) that can be independently manufactured, assembled, and maintained. Each module has a defined function and interface, which simplifies the overall system architecture despite the modular design. This segmentation reduces complexity compared to a monolithic system by allowing independent optimization of each component.
