Abstract

Shale gas is a shale rock that has low permeability, so it requires the right way to explore it. Hydraulic fracturing is one of the methods used to increase well productivity by injecting fluid into fractures with high pressure. Linear regression analysis is one of the statistical methods used to establish a relationship between one independent variable X or more and a response variable Y. The purpose of this study was to determine the significant factor parameters for the success of hydraulic fracturing in shale gas. The method used in this study is simulation research using the CMG GEM simulator for reservoir simulation modeling and running sensitivity analysis using CMOST as much as 80 data than performing multiple linear regression analysis with SPSS (Statistical Product for Service Solutions). There are six parameters used for the sensitivity analysis of factors that are significant for the success of hydraulic fracturing, namely fracture half­ length, matrix porosity, young elastic modulus, natural fracture porosity, Poisson ratio, and Langmuir pressure. The results of the T-test which were carried out partially sequentially showed that variable Xl (fracture half-length) had an effect with a significant value of 0.985 > 0.05, variable X3 (young elastic modulus) had a significant value of 0.734, variable X4 (natural fracture porosity), and variable X6 (Langmuir pressure) significant value of 0.088. In addition to the results of the F hypothesis, there is a simultaneous (together) Fcount value of 11,231. While the value of R Square (R2) is 0.480 if it is a percentage, the result is 48%. It can be concluded that the six independent variables affect the dependent variable by 48%. The remaining percentage of about 52% is influenced by other independent variables, which are not examined in this study.
