Advanced Radial Flow Test System

Purpose of the advanced radial flow test system:

The circular radial bench is a mechanical testing apparatus designed to replicate the fluid drainage/circulation stages during drilling as faithfully as possible.

The focus is on fluids that can be damaging at the well/reservoir interface during drilling.

Objectives of Testing:

The primary objective is to accurately calculate the percentage of damage and the invasion rate of these fluids/solids inside the rocks or sands used.

Operating Conditions:

The bench is capable of reproducing pressures up to 400 bar, temperatures up to 250°C, and resistance to strong acids (HCl 15%).

Radial injection of various fluid types into rocks or sands is possible, including brines, mineral oils (Marcol 52), mud (water-based or oil-based containing solids such as carbonates or other fibrous solids, polymers, etc.), and treatments based on weak/strong acids (HCl 15%).

Injection of gases (such as nitrogen) into rocks with varying porosity, permeability, and composition is supported.

Fluid Characteristics:

The density of fluids entering the cell ranges from 0.80 to 2.2 sg (specific gravity).

Realistic Simulation:

The sequences of fluids and injection rates are consistent with those used in oilfield operations.

The bench is capable of producing a map of damage, providing a comprehensive view of the effects of fluid circulation on the materials.

Overall, the Circular Radial Bench is a versatile testing apparatus designed to simulate and study the effects of various fluids and conditions encountered during drilling. It allows for precise control over pressure, temperature, and fluid types, making it a valuable tool for understanding and mitigating potential damage to reservoir rocks or sands during drilling operations.
