Injeksi CO2 pada shale gas reservoir tidak hanya dapat memerangkap CO2, tetapi
juga dapat meningkatkan produksi shale gas yang terkandung di dalamnya. Hal ini
disebabkan oleh perbedaan kapasitas adsorpsi antara komponen gas CO2 dan gas
CH4. Ketika CO2 diinjeksi ke dalam shale gas reservoir, akan terjadi adsorpsi gas
CO2 ke dalam batuan dan menggantikan shale gas, sehingga shale gas dapat
terlepas dari batuan dan terproduksi ke permukaan. Berdasarkan hal tersebut,
injeksi CO2 ke dalam shale gas reservoir dapat menjadi solusi yang cukup
menjanjikan untuk CCUS (Carbon Capture, Utilization, and Storage) Shale Gas
Recovery. Skenario injeksi CO2 memiliki pengaruh besar terhadap keberhasilan
CCUS
Dalam skripsi ini, akan dilakukan studi mengenai strategi injeksi CO₂ dan
dampaknya terhadap reservoir shale gas, pemerangkapan CO₂, dan perolehan shale
gas yang terkandung di dalamnya. Strategi injeksi yang dianalisis meliputi injeksi
CO₂ secara terus menerus dan injeksi CO₂ selama 5 tahun dengan penutupan sumur
produksi. Selain itu, dilakukan sensitivitas laju injeksi
Injeksi CO₂ ke dalam reservoir shale gas mempengaruhi distribusi tekanan di dalam
reservoir t. Injeksi gas CO₂ memberikan support pressure ke dalam reservoir.
Selain itu, laju injeksi CO₂ ke dalam reservoir shale gas berpengaruh terhadap
produksi C₁, di mana semakin besar laju injeksi, semakin banyak pula gas
incremental C₁ yang didapatkan hingga pada titik tertentu. Namun, apabila laju
injeksi CO₂ ditambah lagi, maka akan mengurangi gas incremental C₁. Pada model
konseptual ini, strategi INJECTION dengan Injection Rate sebesar 20.000
MMscf/day menghasilkan gas incremental C₁ sebesar 11,38 Bscf dan CO₂ yang
tersimpan sebesar 4,65 Bscf. Sedangkan strategi INJECTION_OPEN dengan
Injection Rate sebesar 10.000 MMscf/day menghasilkan gas incremental C₁ sebesar
6,86 Bscf dan CO₂ yang tersimpan sebesar 11,91 Bscf

ABSTRACT
ANALYSIS OF CO2 INJECTION RATE FOR CCUS
SHALE GAS RECOVERY USING CONSEPTUAL
MODEL

The injection of CO₂ into shale gas reservoirs not only captures CO₂ gas but also
enhances the production of the shale gas contained within. This is due to the
difference in adsorption capacity between the gas components CO₂ and CH₄. When
CO₂ is injected into the shale gas reservoir, the adsorption of CO₂ gas into the rock
occurs, replacing the shale gas, allowing the shale gas to be released from the rock
and produced to the surface. Based on this, CO₂ injection into shale gas reservoirs
can be a promising solution for CCUS in shale gas recovery.
This thesis will conduct a study on CO₂ injection strategies and their impacts on
shale gas reservoirs, CO₂ sequestration, and the recovery of shale gas contained
within them. The injection strategies analyzed are continuous CO₂ injection and
CO₂ injection for 5 years with the closure of production wells. Sensitivity analysis
on the injection rate was conducted for all strategies, resulting in different
distributions of pressure and gas production.
The injection of CO2 into a shale gas reservoir significantly impacts the pressure
distribution within the reservoir, providing necessary support pressure. The rate of
CO2 injection also influences the production of methane (C1). Initially, a higher
CO2 injection rate leads to an increased amount of incremental C1 gas. However,
beyond a certain threshold, further increases in the CO2 injection rate result in a
decrease in incremental C1 production. In this conceptual model, the INJECTION
strategy, with an injection rate of 20,000 MMscf/day, yields an incremental C1
production of 11.38 Bscf and a CO2 storage of 4.65 Bscf. Conversely, the
INJECTION_OPEN strategy, with an injection rate of 10,000 MMscf/day, results
in an incremental C1 production of 6.86 Bscf and a CO2 storage of 11.91 Bscf.
