Abstract

This experimental research focuses on investigating the tracer characteristic curves for fracture-cave structures in a carbonate oil and gas reservoir. Fractures and caves are critical geological features that significantly impact fluid flow and hydrocarbon distribution within carbonate reservoirs, making their understanding crucial for optimizing oil and gas production. The study involves laboratory experiments using specially designed models to simulate the complex reservoir conditions. Tracers were injected into the model to track fluid movement through the fracture-cave network. The collected data were used to construct tracer characteristic curves, providing insights into flow behavior, connectivity, and storage within the reservoir. The findings have significant implications for reservoir management, well placement, and enhanced oil recovery techniques, ultimately leading to more efficient hydrocarbon production and improved recovery rates.
