Modular LCM Testing Apparatus for Vugular Formation Simulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for testing lost circulation materials (LCMs) in subterranean formations are not repeatable and fail to accurately simulate the wide range of vug sizes, particularly large vugs, making it difficult to compare the effectiveness of different LCMs.
Innovation Solution
A scalable and repeatable testing system that includes a pressurized tank with a permeability plugging apparatus (PPA) cell and an LCM cell, where an LCM slurry is pressurized and introduced into a simulated vugular formation environment, allowing for the measurement of fluid containment and plug effectiveness under controlled temperature and pressure conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If current test methods are used for testing LCMs, then testing can be performed, but the tests are not repeatable and cannot accurately model large vugs
Solution Approach 1:
The formation simulation component is divided into multiple modular elements (plates with holes, spacers) that can be stacked in different configurations. This segmentation allows the system to accurately model various vug sizes and formation characteristics while maintaining test repeatability through standardized modular components.
Solution Approach 2:
The system allows changing physical parameters such as vug size, formation permeability, and fluid properties by replacing or reconfiguring the modular formation simulation components. This enables accurate modeling of different formation conditions while maintaining consistent testing protocols for repeatability.
2Adaptability or versatility
If a fixed testing apparatus is used, then the device is simple, but it cannot accommodate the wide range of vug sizes needed to simulate vugular formations
Solution Approach 1:
The formation simulation component uses segmented modular plates and spacers that can be stacked in various combinations. This allows the system to accommodate a wide range of vug sizes from small to large by simply changing the number and arrangement of modular elements, rather than requiring completely different apparatus for each vug size.
Solution Approach 2:
The testing apparatus is designed with dynamic reconfigurability, allowing the formation simulation component to be adjusted between tests. The modular plates, spacers, and connectors enable easy reconfiguration to model different vug sizes and formation characteristics while maintaining a relatively simple base structure.

AI summary
An apparatus for testing lost circulation materials (“LCMs”) for use in a formation is disclosed. The apparatus may comprise a LCM cell that contains at least one formation simulation component. A pressurized tank may be in fluid communication with the LCM cell, and may force a sample LCM slurry into the LCM cell. An LCM receiver may also be in fluid communication with the LCM cell, and may receive the LCM slurry that flows through the LCM cell.
