Abstract

In month of August, year 2021, there was an alteration in the production-sharing contract for this field. The contract previously used was Production Sharing Contract (PSC) Cost Recovery, which changed to PSC Gross Split. This contract comparison aims to synergetically evaluate the comparison of the two economic models and also to determine a more efficient and appropriate scheme to be applied to field A, as well as to analyze the parameters that can affect the economic indicators of field A. The results of the economic analysis that has been carried out show that the PSC Gross Split scheme is better than the PSC Cost Recovery scheme. For PSC Cost Recovery, the Net Present Value (NPV) obtained for 30 wells is equal to 13,848,000 US$, the average Interest Rate of Return (IRR) is 118%, the average Pay Out Time (POT) is 1.43 years, the Contractor Take is 20,740,000 US$, and the Government Take is 176,587,000 US$. Whereas for PSC Gross Split, the NPV obtained for 30 wells was US$ 37,906,000, the average IRR was 245%, the average POT was 1.30 years, the Contractor Take was US$ 52,544,000, and the Government Take was 136,402,000 US$. The sensitivity analysis that has been carried out shows that the parameters of the amount of oil production and the price of oil have a significant effect on both schemes.

Abstract

Knowledge and calculation of the nature of fluid flow in sloping reservoirs is very important in oil and gas exploration activities, because on its journey from the source rock (source rock) to migrate to the reservoir, the fluid will pass through rocks which are often non-structural in the form of slopes. in the reservoir. Therefore, calculating oil and gas flows for sloping reservoirs is very important. Slope fault theory is a new idea in searching for non-structural reservoirs, because it is increasingly difficult to find large-scale structural reservoirs. Therefore, structural-lithological reservoirs in slope areas have gradually become the focus of exploration, and on slopes are favorable places for oil and gas accumulation. To calculate fluid flow in a sloping reservoir using the derivation of the Darcy equation, the datum level is a variable that can be selected from the bottom point to the top point of the reservoir height. The problem is whether the flow velocity calculation results are the same for any point. This is to make measurements easier in oil and gas fields. This research will prove that random selection of the datum level does not change the flow velocity value of the flowing fluid. Firstly, in this article, the fluid flow velocity will be calculated using the three datum level points used. Calculations use the usual/manual method with a calculator and it is proven that the calculation results are the same. Then all points from the bottom to the top of the reservoir height will be calculated. The method that will be used uses a lot of data to prove the results are the same. Because there are quite a lot of calculations, the calculations will be calculated numerically by coding using the Fortran program. It turns out from the programming results that the fluid flow rate in a sloping reservoir has the same value using datum level data calculated from the bottom to the height of the reservoir with an increase of every 1 ft. So it is concluded that calculations using datum levels can be done anywhere in the height range of oil and gas reservoirs.

Abstract

Socialization of the utilizations and advantages of city gas is a community service that aims to make people understand the growth of the urban gas distribution sector in Indonesia and provide information to the public about LPG substitute economic energy sources. Gas network for households means distributing gas through pipes to households. The limited availability of household gas in DKI Jakarta made this socialization theme raised. The location chosen is the Tanjung Gedong area, Tomang-sub distrct, Grogol Petamburan district, West Jakarta, which in this case, the area is a densely populated area, especially family settlements. The participants who took part in this community service were housewives.  The method used is to provide socialization about the urban gas network developed by the government for household gas purposes, the socialization is carried out online with the zoom facility and some others offline in the community while still using the existing health protocol. The result of this community service activity is that the public is able to recognize and understand the existence of a gas network whose infrastructure development is being developed by the government through PT PGN Tbk. This community service makes the community clearly aware of the flow in the “jargas” development program.

Abstract

The assessment of geothermal well production capability plays a crucial role in optimizing geothermal energy generation systems. This study focuses on evaluating the performance of two geothermal wells, ZM-42 and ZM-31, located in the AAP Field, by developing output curves through wellbore simulation techniques. The analysis utilizes field production test results, well casing configuration data, and PTS (Pressure, Temperature, and Spinner) survey data to generate key parameters such as wellhead pressure, fluid flow rate, fluid temperature, enthalpy, and vapor fraction (dryness). These parameters are essential for understanding the thermal and flow characteristics of each well. Wellbore simulations were conducted using specialized software to replicate the flow behaviour of geothermal fluids within the well system. The output curves produced provide a graphical representation of the relationship between wellhead pressure and mass flow rate under various operating conditions. Validation of the simulation was done by comparing the generated curves with actual field measurements. The results show that well ZM-31 demonstrates a higher production capability compared to ZM-42. ZM-31 recorded a flow rate of 96.61 kg/s and an enthalpy of 1134.5 kJ/kg, with a vapor fraction of 0.14. In contrast, ZM-42 exhibited a lower flow rate of 85.60 kg/s, enthalpy of 1027.7 kJ/kg, and a vapor fraction of 0.11. These differences indicate superior separation efficiency and thermal performance in ZM-31. Furthermore, ZM-31’s production is dominated by a single feed zone, while ZM-42 relies on multiple contributing zones. In conclusion, based on output curve analysis and well simulation results, ZM-31 is recommended as the primary production well for further optimization in the AAP geothermal field, contributing to more efficient and reliable energy output.
