Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods lack the ability to quantitatively assess the impact of stabilizing additives on the settling rate of destabilized solids in oil-based fluids, such as asphaltenes and polynuclear aromatics, making it difficult to determine the optimal dosage for field applications, which can lead to equipment fouling and reduced production efficiency.
Innovation Solution
A method involving preparing samples of oil-based fluids with and without a stabilizing additive, measuring the settling rate using turbidity or nephelometry, and quantifying the difference in settling rates to evaluate the additive's performance, allowing for adjustments in additive dosage based on the results.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If stabilizing additive is added to oil-based fluid, then the settling rate of destabilized solids is reduced and equipment fouling is prevented, but the cost of operation increases due to additive application
Solution Approach 1:
The patent implements a feedback mechanism by measuring the settling rate of destabilized solids in the oil-based fluid and using this measurement to adjust the dosage of stabilizing additive. The method continuously monitors the concentration of destabilized solids and modifies the additive application rate accordingly, ensuring optimal fouling prevention while minimizing unnecessary additive usage and associated costs.
Solution Approach 2:
The patent changes the dosage parameter of the stabilizing additive based on measured settling rates. By adjusting the additive concentration in response to observed settling behavior, the system optimizes the balance between preventing equipment fouling and controlling operational costs, avoiding both under-dosage and over-dosage scenarios.
2Stability of the object's composition
If stabilizing additive is added to oil-based fluid, then the stability of the fluid is improved, but the complexity of the process increases due to the need for quantitative assessment
Solution Approach 1:
The patent replaces complex manual assessment procedures with automated optical measurement systems. By using light scattering or absorption techniques to measure the settling rate and concentration of destabilized solids, the system achieves accurate fluid stability assessment without requiring complex mechanical or manual evaluation methods, thereby simplifying the overall process while maintaining high measurement accuracy.
Solution Approach 2:
The patent introduces an intermediary measurement system that indirectly assesses fluid stability by measuring the settling rate of destabilized solids. Rather than directly measuring complex fluid stability parameters, the system uses the settling behavior of solids as an intermediary indicator, simplifying the assessment process while providing reliable information for controlling additive dosage.
3Reliability
If the dosage of stabilizing additive is increased, then the settling rate of destabilized solids is further reduced, but the energy consumption increases
Solution Approach 1:
The patent uses feedback control to adjust additive dosage based on measured settling rates. By continuously monitoring the actual performance of the stabilizing additive and modifying the dosage in response, the system avoids excessive additive application that would waste energy, while ensuring sufficient dosage to prevent equipment fouling and maintain optimal fluid stability.

Function Achieved in This Case
This method enables a quantitative assessment of the stabilizing additive's impact on the settling rate of destabilized solids, facilitating better decision-making for additive application and improving operational efficiency by preventing fouling and reducing energy consumption.
Implementation Method 1
measuring the difference in the settling rate of the flocculated destabilized solids in each sample to evaluate the performance of the stabilizing additive
Implementation Method 2
The method may further include implementing a change to the amount of stabilizing additive applied to the oil-based fluid based upon quantifying the difference between settling rate of the flocculated destabilized solids in the sample of the oil-based fluid having a field dosage amount of stabilizing additive and the settling rate of the flocculated destabilized solids in the sample of the oil-based fluid having no stabilizing additive. In another form, the settling rate is measured using a turbidity meter or nephelometer located in the field.

AI summary
The impact of a stabilizing additive for treating oil-based fluids having destabilized solids, such as asphaltenes and polynuclear aromatics, may be quantitatively assessed, by determining the settling rate of flocculated destabilized solids in samples of untreated oil-based fluids and oil-based fluids treated with the stabilizing additive through the use of a turbidity meter or nephelometer while the field and quantifying the difference between the two settling rates to determine if a change in the amount of stabilizing additive applied to the oil-based fluid is necessary.
