Abstract

Oil and gas industry is struggling to improve oil production using several methods. CO2 injection is one of the advance proven technology to enhance oil production in numerous oil field in the world.  Key parameters during CO2 injection are viscosity reduction and oil swelling which can improve oil production. CO2 injection also has high possibility to be applied in Indonesia's oil fields due to abundant CO2 sources surrounding oil fields. R field is one of reservoir candidates that appropriate for CO2 injection. It has a low pressure and low oil recovery due to low permeability (1-26,2 mD).The CO2 injection technique used in this study was huff and puff that consist of injection, shut in, and production phases. The simulation was conducted using compositional simulator. There were two parameters chosen to be analyzed, which were soaking time and injection cycle. The objective of this study is to know the CO2 huff and puff perfomance for improving oil recovery on low permeability reservoir. The result of the soaking time cases yields optimum condition in 21 days. For the case of injection cycle, the result for optimum condition is in 2 injection cycles. The recovery factor (RF) for both optimum condition reaches 22.96% from the baseline without gas injection (RF 5.82%).

Abstract

Islamic Religious Education (PAI) needs to be designed actively so that students not only understand the material but are also interested, engaged, and able to connect Islamic values with their lives. This article aims to analyze Inquiry Learning-based PAI learning strategies in increasing students' learning interest. The study uses a library research method with a qualitative-descriptive approach. Data were obtained from journal articles and scientific documents discussing PAI learning, Inquiry Learning, and learning interest. The results show that Inquiry Learning has the potential to increase learning interest through the provision of contextual stimuli, formulation of questions, information searching, discussion, testing of understanding, drawing conclusions, and reflection. Its effectiveness is influenced by teacher readiness, quality of teaching materials, use of varied media, a communicative classroom atmosphere, and mentoring for students who are still passive. With systematic planning, Inquiry Learning can make PAI learning more meaningful, participatory, and oriented towards the formation of knowledge, attitudes, and the practice of Islamic values.
