VERTICAL-HORIZONTAL PERMEABILITY RELATIONSHIPS IN STRESS AND NON STRESS SENSITIVE RESERVOIRS

VERTICAL-HORIZONTAL PERMEABILITY RELATIONSHIPS IN STRESS AND NON STRESS SENSITIVE RESERVOIRS

Abstract:
Understanding the permeability behavior of reservoir rocks is crucial for successful hydrocarbon exploration and production. This study focuses on investigating the vertical-horizontal permeability relationships in stress and non-stress sensitive reservoirs. The permeability anisotropy, characterized by the variation in flow properties along different directions, plays a significant role in reservoir performance and fluid flow patterns.

In stress-sensitive reservoirs, such as those subjected to tectonic forces or hydraulic fracturing, the permeability is known to be influenced by stress-induced changes in rock fabric and fractures. This study examines the impact of stress on the permeability anisotropy and aims to quantify the degree of anisotropy under different stress conditions. Various laboratory techniques, including core analysis and rock mechanics experiments, are employed to measure and compare the vertical and horizontal permeability values.

Furthermore, the study also investigates the permeability behavior in non-stress sensitive reservoirs, where the stress regime remains relatively stable over time. By analyzing core samples from these reservoirs, the research aims to identify the inherent permeability anisotropy and understand the geological factors that control it. This knowledge can provide valuable insights into the reservoir connectivity and the preferred pathways for fluid migration.

The findings of this study contribute to the broader understanding of permeability anisotropy in both stress and non-stress sensitive reservoirs. The quantification of vertical-horizontal permeability relationships can help optimize reservoir management strategies, such as well placement and hydraulic fracturing design, to maximize hydrocarbon recovery. Moreover, the results can aid in the development of accurate reservoir simulation models, leading to improved predictions of fluid flow behavior and more reliable production forecasts.
