Abstract

Along with the development and progress of human civilization, the need for electrical energy continues to increase. For this reason, new energy sources are needed so that energy needs can be met. Carbon dioxide (CO2) can be a new energy source obtained from industrial waste energy processing. CO2 is a type of emission that can cause the formation of greenhouse gas (GHG) emissions and contributes to global climate change. A 6% increase in emissions from 2020 results in emissions of 36.3 giga tons (Gt). One utilization of CO2 emissions that can be done is to convert CO2 emissions into electricity. The data analysis method is done by comparing the technical and economic parameters between the rankine power cycle using H2O as the working fluid and the Allam power cycle using CO2 as the working fluid. The results obtained are that the natural gas-fired Allam cycle has a net HHV and LHV efficiency of 53.17% and 58.90%, respectively. For the coal-fired Allam cycle, the net HHV and LHV efficiencies obtained were 48.88% and 51.44%, respectively. The economic analysis conducted is LCOE, IRR, and NPV. The economic analysis shows that the project is feasible in terms of electricity cost.

Abstract

The wells in Field J, using Electrical Submersible Pumps (ESP), have replaced their natural flow operations. To optimize this ESP well and pipeline network, the research focuses on adjusting the ESP pump frequency within the Pipesim simulator, increasing it to enhance oil flow rates. This study employs a quantitative approach, where field data is analyzed and input into a simulation model that replicates real-world conditions. The analysis encompasses changes in flow rates and pressures, comparing the base case to post-optimization simulations. The results indicate a substantial increase in the initial oil flow rate from 578 STB to 720 STB/d, with an increase of 142 STB/d, when the pump frequency is raised to 60 Hz. This frequency adjustment significantly boosts pump discharge pressure, providing the added energy needed to transport fluid to the surface.

Abstract

This research evaluates the performance of an existing stripper in handling H2S content in the oil stream in Sukowati Field, Bojonegoro Regency. With H2S content ranging from 2-3%, there's a risk of danger and damage to the piping system. The study aims to assess the stripper's performance, propose an optimization scenario for managing H2S content, and compare the existing stripper's performance with the optimization scenario. The research involved evaluating the stripper from October to December 2023, formulating an optimization scenario, and implementing it in January 2024. Results indicate that the % absorption ratio in the sweetening process averaged 98.99% in the existing stripper and 99.75% in the optimization scenario. The oil rate to sweetening gas ratio averaged 89.31% in the existing stripper and 88.01% in the optimization scenario. The sweetening gas injection to oil rate ratio averaged 10.7% in the existing stripper and 12.0% in the optimization scenario. The optimization scenario reduced H2S content from 24000 ppm to 60 ppm, meeting standards. Overall, optimizing the oil rate to sweetening gas injection ratio improved H2S content reduction efficiency in the stripper, with H2S content at the outlet less than 100 ppm.
