Abstract

Oil production that flows from the Platform to the FSO (Floating Storage and Offloading) "A" is derived from PT. "B" and the "C" Oil Company in the Madura Strait. The total oil production flowing from the Platform to the "A" FSO is currently around 6000 BOPD. As a result of the delivery system using the same channel, a problem arises, namely oil losses between the Platform as a delivery point and FSO "A" as a receiving point. Besides that, the water that is involved in the oil distribution process will be a deduction factor that will be used as a correction for oil shipments, the more water the less amount of oil will be received at FSO "A". The oil samples that have been taken are then observed for their characteristics, namely density, composition (%-mole), BS&W, emulsion, flash, shrinkage at PPPTMGB "Lemigas" Laboratory Jakarta. The specific gravity of samples is around 1,018. While the characteristics of the two are different from the characteristics of sea water; this difference is shown by the results of SG (1,018 vs 1,025) and the salt content of sea water is much higher than the water formation of PT "B" and PT "C". The oil samples of PT "B" and PT "C" have almost the same SG, which is 0.79. BS&W oil in both ships is quite low; this shows that the separation of oil and water on the Platform went quite well. However, BS&W samples in incoming FSO "A" are very high, at 5%; this indicates an off-set at the water-oil interface level settling time on the Platform separator so that water can be joined with the oil flow from the Platform to the FSO "A"

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

The displaccment of one fluid by anolhcr is con-trolled by the geometry of the pore space. The relativehydrodynamic conductance of each fluid at a givcn satu-ration is the relative permeability, while the pressure dif-ference between the phascs is the capillary pressure.These two functions determine the macroscopic fluidtlow behavior in hydrocarbon reservoir over the scaleof centimeters to kilometers.

Abstract

Pengembangan (swelling) minyak dan tekanan tercampur minimum (TTM) merupakan dua faktor yang penting dari mekanisme pendesakan gas karbondioksida (CO2 ) yang terjadi di reservoir untuk penerapan injeksi CO2 di lapangan dalam upaya meningkatkan perolehan minyak tahap lanjut. Dalam paper ini penentuan swelling factor dilakukan menggunakan PVT cell, dimana fluida rekombinasi diinjeksikan dan dikondisikan pada temperatur reservoir. Sedangkan penentuan TTM antara sampel minyak dengan gas CO2 dilakukan menggunakan tiga cara, yaitu persamaan empiris, secara korelasi dan percobaan laboratorium menggunakan Slimtube. Berdasarkan hasil analisa swelling test selama proses injeksi gas CO2 sampai 46,82% mol, tekanan gelembung meningkat secara bertahap dari 410 psig sampai 2200 psig dan faktor swelling meningkat dari 1.0 sampai 1.442. Penentuan TTM menggunakan persamaan empiris (2807 Psig) dan korelasi Holm & Yosendal (2750 Psig) adalah yang paling mendekati dengan hasil penentuan dari analisa laboratorium (2800 Psig). Didasarkan pada besarnya tekanan rekah formasi di Lapisan F sebesar 2200 Psig dan TTM sebesar 2800 Psig, maka dalam penerapannya di lapangan injeksi gas CO2 hanya dapat dilakukan secara pendesakan tak tercampur.
