Abstract
Description
- In the resource exploration and recovery industry, various components are used to guide fluids along a selected flow path. Backup rings may be employed to guide to support a packer during deployment, and screens may be employed to guide and filter fluid flowing into a tubular. Downhole operations are often performed in harsh operating conditions such as high pressures and high temperatures. It is desirable that components such as backup rings and screens be capable of withstanding such harsh conditions.
- In certain conditions, expansion of a backup ring may be limited by downhole conditions. Screen components may become clogged. Existing backup ring geometry limits a rate and degree of expansion. Similarly, existing screen manufacturing techniques are limited in how screen openings may be formed. Accordingly, the art would appreciate downhole components that are capable of withstanding harsh operating conditions for prolonged periods.
- Disclosed is a resource exploration and recovery component including a fractal geometry.
- Also disclosed is a resource exploration and recovery system including a first system and a second system fluidically connected to the first system. The second system includes a tubular. A tool is supported by the tubular. The tool includes a fractal geometry.
