The core sampling procedure must be carried out properly in order to produce cores of good quality. A good core sample will have an effect on the accuracy of the data that will be used. The core sampling method consists of Drill-string Coring and Wireline Coring. Enhanced Oil Recovery (EOR) study is a laboratory study to measure compatibility and amount of recovery. In that laboratory study, core samples from the reservoir are required to be carried out by the Enhanced Oil Recovery (EOR) study. Because the cost of taking the original core samples from the reservoir is quite expensive, usually the core samples used in this study are often called artificial core. A good candidate for an artificial core is a core that has similar characteristics and properties to the condition of the reservoir. The candidate quality of core samples is very important because the sample will represent the properties of the reservoir. By evaluating physical properties of the rock such as porosity, permeability, rock mineralogy, and the distribution of physical properties in the core sample, the best quality of the core sample will be obtained where the sample can represent the reservoir in the research area that Enhanced Oil Recovery (EOR) study will be conducted.
