Abstract

Field experience shows that, when two or more oils have different densities mixtures and transported throughthe pipeline at the same time, the mixtures will form a new characteristics of oils that different than oilsinitially, then the volume of the oil mixture is delivered from the SP ( Gathering Station), as the transferpoint, the volume will be different on the tank received. Differences between the sending and receiving ofthese so-called oil losses. One factor is the shrinkage volume of oil that caused the process of mixing two ormore of oils which have different characteristics in the pipeline or tank .Laboratory testing use to calculateshrinkage of oil, but the other use the American Petroleum Institute method.In a case study conducted in theoil field X in South Sumatra there are some groups that have different characteristics of petroleum, andfrom laboratory experiments and mathematical calculations showed that the shrinkage in the Group 1 isequal to 0.115% or 2.386 BOPD, shrinkage in the Group 2 is equal to 0131% or 3.931 BOPD. The amountof shrinkage in Group 3 of 0.476% which is equivalent to 6.748 BOPD and for Group 4 seen that shrinkageof this group amounted to 0.189% or 2.082 BOPD and shrinkage for Group 5 amounted to 5% or 38.507BOPD. While the total shrinkage in the network system from upstream to downstream (group 1- 5) isapproximately 0.257%, or approximately 54.37 BPOD

Abstract

CO2 gas injection is once of recommended Enhanced Oil Recovery (EOR) methods by injecting CO2 through reservoir pore after reached its residual saturation, since CO2 dissolved easily in oil phase due to oil extraction as confirmed by many other researcher in pertaining field study. An integrated system is urgently required for assessing CO2-EOR feasibility study, covering multi disciplinary aspects as follows: geology, geophysics, reservoir, production, process and economic. Hence those systems must be reliable in suggesting final decision for feasibility study of CO2-EOR operation program, applicable either for pilot scale or full scale. This paper will proposing integrated system evaluation, which has following features:  (1) Estimate fraction of dissolved CO2,(2) Estimate viscosity reduction, (3) Estimate future of oil productivity index resulted, (4) Estimate forecast of incremental oil recovery, (6) Estimate surface facilities equipment design, (7) Evaluate economical aspects, and (8) Generate final decision for feasibility of CO2-EOR operation program. Finally, as the main objective of this program, those system will present a picture of essential reason why we need to promote or reject CO2-EOR plan program, also some recommendations will presented in case of CO2-EOR plan does not perform from what it is supposed to be.
