Abstract

Carbondioxide (CO2) injection is a very effective and proven technology for enhanced
oil recovery (EOR). Minimum miscibility pressure (MMP) and oil swelling are two
important factors of the CO2 gas displacement mechanism that occurs in the reservoir
when CO2 injection is applied to enhance oil recovery. In this study, MMP
determination between crude oil samples and CO2 gas has been conducted using
three methods, i.e., empirical equation, correlations method, and laboratory
experiment using slimtube. The determination of the swelling factor was conducted
using a PVT cell, where recombined fluid is injected at the reservoir temperature. The
MMP value from the empirical equation (2810 psig) is relatively close to the MMP
value from the laboratory experiment (2807 psig), with a difference of 3 psig. The
swelling test results show that the bubble point pressure and the swelling factor
increase from 410 psig to 2200 psig and from 1.0 to 1.442, respectively, as the CO2
gas injection reaches 46.82% mole. Since the fracture pressure of the KMJ Layer in the
HKY Field is 2200 psig and the MMP is 2807 psig, only immiscible CO2 flooding can be
applied in the field because the CO2 MMP is higher than the fracture pressure
