Abstract

"This thesis presents a correlation analysis of the spatial distribution and permeability of magnesite dissolution and focuses on its overall rate and average porosity. Magnesite dissolution is affected by several aspects.

A reservoir's large spatial distribution can make capturing the magnesite dissolution difficult, so in this study, a variogram was built in Petrel using a percentage variation of magnesite and sand. The variogram also handles different major and minor directions in anisotropy. After building the magnesite model, simulation of magnesite dissolution was achieved in Cruch Flow to get the magnesite dissolution rate and average porosity.

For correlation analysis, a regression model was used to build a linear relationship in the correlation analysis. Areas of study included major anisotropy, permeability, minor anisotropy, and percentage of magnesite with dissolution rate and average porosity. The mean of all data was calculated with 95% confidence intervals, and the original data were judged at almost normal value. Finally, correlation analysis included all independent variance with dissolution rate and average porosity.

From all analysis, can find the most important parameter is the percentage of magnesite and sand, next is the major and minor anisotropy, and permeability of magnesite and sand weakest. For a percentage of magnesite has positive correlation with overall rate and average porosity, major anisotropy and permeability have a positive correlation with overall rate and negative correlation with porosity, minor anisotropy has both negative correlation with rate and porosity"--Abstract, page iii.
