CO2 Utilization : CO2 EOR in Jatibarang Field
As a first step towards full scale, CO2 injection can be done using the Huff & Puff method because the CO2 requirement is much lesswhen compared to a full-scale project, so that the costs will be less, and the execution of the work is simpler.
Project Overview

Project Objective
1. To strengthen sustainability portfolio
2. To Increase oil production recovery as much as 13 % from CO2EOR

Methodology: Huff & Puff
• Investigate “miscible” CO2-EOR effect, evaluate CO2 Infectivity
into the formation and field Operation Assessment.
• Huff and Puff will also act as a risk mitigation before Full Field
application.
Expected results: Oil rate increase, water cut reduction, oilsaturation reduction, fluid property change observed.

CH4 Utilization : POME to Biomethane

Low Hanging Fruit Initiative to Tackle Climate Change & Build New Green Business
Palm oil for Renewable Gas

Palm Oil Mill Effluent (POME) is a waste-based feedstock that is collected at palm oil mills during the palm
oil production process. It has been acknowledged as a suitable feedstock for biofuels in the EU Renewable
Energy Directive (RED) II. Every ton of CPO produced generating an average of 2.43 ton of POME.
PROJECT PROFILE◼ Partner Companies◼ Project Activity◼ Biomethane prod. rate

The CF of electricity generation fromgeothermal energy is a highest andthe most stable compared to other
NRE sources.
Due to its stability and reliable
source, geothermal is used as a baseload in the grid.
Baseload energy - it's always on: GPP
