Abstract

Different flow region will form in the reservoir when the gas condensate fluid flows with a bottom hole pressure below the dew point pressure. This flow region can be identified by the pressure build-up test analysis. This analysis can be done well on reservoir with homogeneous system and becomes more complex on reservoir with heterogeneous system. The purpose of this study is to find informations and characteristics about carbonate reservoir with gas condensate. Reservoir parameters that can be obtained are initial reservoir pressure (pi), permeability (k), skin factor (s), reservoir boundary (boundary), drainage area, and average reservoir pressure ( pr ). "JD-1" exploratory well penetrated the carbonate formation with the gas condensate hydrocarbon content. The well test analysis conducted is pressure analysis with pressure build-up testing and theanalysis results show a reservoir with a two-layer model, permeability value of 154 md, skin 13.8, initial pressure 3286.3 psia, and average reservoir pressure of 3285.7 psia.

Abstract

The purpose of calculating the Original Oil In Place (OOIP) is to know the potential of reservoir to be produced. Calculation of OOIP in field Y based on determining the type of drive mechanism at the beginningfollowed by calculation the value of Underground Withdrawal and parameters of fluid expansion. All parameters then used to draw the graphic using Havlena and Odeh Method. The value of OOIP is 354,766 MMSTB.Along with the time and production activity, the OOIP will be reduced. Therefore it is important to forecast the production itself. Constant Decline is determined using Trial Error and X2 Chisquare Test Method with value of constant decline b = 0 and decline rate 0,01855. This means that the type of decline curve is exponential curve. This type of decline curve is used to forecast the production until q economic limit. As a result, the value of Estimated Ultimated Recovery is 296,0386 MMSTB, Recovery Factor 83,4461%, and Remaining Reserve 51,9415 MMSTB. Keyword: Original Oil In Place, Decline Curve Analysis, material balance straight line, Recovery Factor, Remaining Reserve

Abstract

The Petroleum Industry does not only consist of exploration and exploitation activities, but there are other activities that are also important, namely lifting activities. The lifting activity is one of the transfer/ shipping activities from upstream (Producer) to downstream (Buyer). One of the lifting activities is the calculation of the amount of oil/condensate, which is a calculation of the calculation and reporting of oil/condensate that is applied in managing the distribution of oil/condensate production from the block station to the point of sale. The importance of this calculation system is due to the amount of lifting that will be reported to the state. This needs to be done well to avoid the wrong amount of value. ASTM (American Society for Testing and Materials) is an international organization that develops and publishes technical standards for various materials, products, systems and services. The lifting job based on the conditions established by ASTM can minimize the possibility of errors in calculation of QAS (Quantity Accounting System), in this case specifically for fluid level measurements in tanks, temperature measurements, methods and techniques for measuring the number of samples, proving job, laboratory analysis (such as Density, BS&W, etc), and the methods that must be used (Flow Meter or Meter Tank Gauging) for QAS input. This paper is made using reference activities that happen in lifting points in Riau Province, North Sumatra Province, and Aceh Province. It is expected to provide more understanding of the necessary of applying the ASTM provisions to lifting activities.

Abstract

A good reservoir management is needed to maintain the availability and quality of geothermal production fluid. When producing geothermal fluids, there are some changes in reservoir parameters such as declining of reservoir pressure and temperature, chemical composition of geothermal fluids, and states of fluid that would affect the quality of reservoir by mixing, boiling, or cooling processes that may be happened because of those changes. It is becoming a concern on reservoir management. In this case, chemical concentrations of fluids monitoring is one of methods that can perform to reach a well reservoir management of geothermal field. With chemical monitoring process, current reservoir condition and processes that occurred during exploitation can be defined. In ELS-02 by monitoring and analyzing its enthalpy changes, chloride concentration changes, and NCG concentration changes and supported by its calcium, sulphate, and carbonate concentration profile, two processes could be defined: mixing with surface cooler water and reinjection breakthrough. Other than that, casing leak that causing surface water enter the well could be detected.  These become a sign to reservoir engineer to prepare for problems that may occur in near time term relating to well problem such as scaling and long time problem like massive cooling or drying of reservoir. After all, further development scenario of Elsa field can be made to improve its performance in producing fluids and heats.
