The determination of this variable is critical for the success of the operation. The most accurate method to obtain the value of MMP is slim-tube tests. Nevertheless, slim-tube test and other experimental technics are expensive and time-consuming. Based on this problem, it is common to find so many publications discussing mathematical correlations for the value of MMP since correlations require few input variables. Many existing CO 2 MMP correlations are constructed based on the slim-tube tests. Many of them are intended to calculate the MMP for lower-temperature reservoirs compared to the typical reservoir temperature in Abu Dhabi. Hence, Alshuaibi et al. (2019) establish a new correlation to determine CO 2 MMP for high-temperature reservoirs. However, the published correlation including the coefficients is not matched with the result. This study will be focused on proposing new coefficients for Alshuaibi et al. (2019) correlation and establishing a new correlation based on the 17 complete slim-tube data. Eureqa-Formulize will be used as the software to construct the new correlation considering the machine learning method may not be reliable due to the few data. Furthermore, this correlation will be improved by using two methods. These methods will use combined two data sets and will be processed according to each method.
