AN INTEGRATED APPROACH TO ASSESSING OIL DISPLACEMENT EFFICIENCY BY WATER IN FRACTURED-POROUS CARBONATE RESERVOIRS
Main Article Content
Abstract
This paper presents an integrated methodology for the quantitative assessment of Oil Displacement Efficiency by Water (ODEW) in fractured-porous carbonate reservoirs using a multivariate statistical analysis. We examine the geological-physical and engineering parameters crucial for defining the efficacy of waterflooding processes in both reefal and depression-type carbonate formations. The study proposes advanced regression models that correlate ODEW with parameters such as porosity, areal and vertical sweep efficiency, heterogeneity, and initial water saturation. Statistical analysis was conducted using a database encompassing 21 fields in the Bukhara-Khiva region, resulting in the construction of correlation matrices and subsequent verification of the models against field data from the Severny Urtabulak and Kukdumalak assets. Our findings establish that the sweep efficiency factor exerts the most significant influence on the resultant ODEW value. The derived dependencies provide a predictive tool for estimating oil displacement performance and can be utilized to optimize Pressure Maintenance Systems (PMS) in reservoirs exhibiting dual-porosity characteristics.
