Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current barite recovery systems in drilling operations are costly, complex, and environmentally challenging due to the need for multiple pumps, tanks, and extensive piping, which can lead to mud spillage and increased operational expenses.
Innovation Solution
A simplified barite recovery system that uses a single pump to feed drilling mud to a decanter centrifuge and a barite recovery hopper, eliminating the need for additional pumps and tanks, and incorporating a hopper bypass gate to manage flow during both weighted and unweighted mud treatments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If multiple pumps, tanks, and extensive piping are used in barite recovery systems, then barite separation functionality is achieved, but system complexity and cost increase
Solution Approach 1:
The patent combines the barite recovery hopper and decanter centrifuge into a single integrated unit, eliminating the need for separate tanks, pumps, and piping that would otherwise be required. The hopper is positioned directly on the centrifuge, creating a compact system that maintains full barite separation functionality while dramatically reducing complexity.
Solution Approach 2:
The integrated hopper-centrifuge system performs multiple functions: it serves as both the receiving hopper for drilling mud and the separation device. The system can handle both weighted and unweighted mud treatments through the bypass gate mechanism, providing versatility without requiring additional equipment.
2Object-affected harmful factors
If extensive piping and multiple tanks are used, then mud circulation is maintained, but mud spillage risk increases
Solution Approach 1:
The patent extracts and eliminates the extensive piping infrastructure that connects separate tanks and equipment. By integrating the hopper directly onto the centrifuge, the system removes multiple pipe connections, flanges, and joints that would be potential leak points, thereby reducing mud spillage risk.
Solution Approach 2:
By merging the hopper and centrifuge into a single unit, the patent eliminates the piping that would connect these two components. The direct integration removes potential leak points and simplifies the fluid path, reducing the harmful effect of mud spillage.
3Productivity
If additional pumps and tanks are installed, then barite recovery capability is enhanced, but operational cost increases
Solution Approach 1:
The patent merges the hopper and centrifuge functions into one integrated unit, eliminating the need for additional pumps to circulate mud between separate tanks and equipment. The system maintains full barite recovery capability while reducing operational expenses associated with multiple pumps and tanks.
4Device complexity
If a simplified system with single pump is used, then operational cost decreases, but barite separation effectiveness may be compromised
Solution Approach 1:
The integrated hopper-centrifuge design maintains effective barite separation by ensuring proper positioning and integration of the centrifugal separation mechanism. The system preserves the essential separation functionality while achieving simplicity through integration, rather than through inadequate equipment.
Solution Approach 2:
The bypass gate acts as an intermediary mechanism that allows the system to handle different types of mud (weighted and unweighted) effectively. This single-component solution maintains separation effectiveness across different operating conditions without requiring additional equipment.

AI summary
A method for treating drilling mud includes directing a first flow portion of a flow of drilling mud to a decanter centrifuge, directing a second flow portion of the flow of drilling mud to a solids particle recovery hopper, and separating an underflow from the first flow portion with the decanter centrifuge, wherein the underflow includes first solids particles having a first density. The underflow is directed to the solids particle recovery hopper, the underflow is mixed with the second flow portion in the solids particle recovery hopper, and a flow of the mixed underflow and second flow portion is directed from the solids particle recovery hopper to an active mud tank.
