Abstract

This research provides the scenario of a field development plant with the primary goal of acknowledging the reservoir model of Kappa Field in determining the optimum field development scenario to increase the recovery factor. In this research, field development will be carried out by creating scenarios that differentiate certain parameters to see the differences from these scenarios. The main problem in this field is to find out the feasibility of a field that has a history of production from 1986 to 2022 or for 33 years. In addition, the main objective of this research is to determine the reservoir driving mechanism of the Pasir RH-7 layer and determine the best field development scenario to optimize production in the Kappa field. The method used in this study is the reservoir modeling method using production data and reservoir data that has been obtained from the company and then managed using the Petrel Software assisted by Eclipse and MatBal. Before developing field development scenarios, an analysis is carried out using several different methods, including analysis with the decline curve analysis method in determining the remaining recoverable reserves as the validation of Kappa Field's feasibility, identify the driving mechanism of the reservoir, and history matching between history production data with simulation results. Sensitivity analysis of the field development is also conducted through various scenarios, including adding or adjusting well perforation interval, infill well adding, five water injection wells, and four gas injection wells. Other than that, injection gas and water rates in injection wells are also being exercised during the sensitivity analysis. Simulation results show the best scenario of Kappa Field is ten infill wells and four injection wells with a water injection rate of 1000 BWPD and gas injection rate of 1 MMSCF/d, giving the optimum recovery factor result of 39.33% from oil reserves. The results of this research will have a positive impact on the development of the Kappa field in order to increase production from fields that have been producing since 1986 and stopped production in 2019.

Abstract

S-7 well is a horizontal well in the NDF Field that produces hydrocarbons from carbonate formation for over seven years using gas lift. Over time, S-7 well has experienced a significant decline in production due to reservoir pressure along with an increase in water cut. To address this issue, a well intervention was conducted to deepen the injection point by installing Retrofit Gas Lift technology, aiming to enhance the well's production to an optimal level. This research focuses on evaluating the application of Gas Lift Deepening using Retrofit Gas Lift (RGL) in Well S-7 through well modeling methods with PROSPER software and providing recommendations for an optimal Gas Lift Deepening design. The study analyzes well modeling for Well S-7 before and after RGL installation, validated using well test data to compare production performance in both scenarios. The evaluation proceeds by identifying the parameters that influence the effectiveness of the Retrofit Gas Lift (RGL), followed by designing an optimized RGL system to enhance production performance. Based on the research, the installation of the Retrofit Gas Lift (RGL) in Well S-7 resulted in an increase in the production rate of 78.58 STB/d. Sensitivity testing identified key factors influencing the production rate, including reservoir pressure, top node pressure, gas injection rate, coil tubing size, and coil tubing length. Design optimization by adjusting the top node pressure to 130 psi, coiled tubing length to 2000 ft, coiled tubing size to 1.75 in, and gas lift injection rate to 1 MMSCFD resulted in an increased flow rate of 220.86 STB/d and a drawdown of 751.77 psi.
