Abstract

Carbon Capture and Storage (CCS) is used at Sleipner Field due to the implementation of a carbon emission tax off the coast of Norway. This project causes the fluid at the Utsira Formation as a reservoir to be replaced by CO2, so the elastic property of the reservoir rock will change. Because of that, the 3D seismic survey was carried out in 1994 (baseline) and re-acquisition in 2001 (monitor) to observe CO2 distribution and changes in rock properties. This study aims to monitor the distribution of CO2 as well as changes in reservoir rock's acoustic and elastic parameters. This research performed the cross-equalization, 4D Seismic Inversion model-based, and rock physics modeling process. From data processing, obtained information that CO2 spreads laterally, then moves to the northeast and does not penetrate the overburden. Also, we get the NRMS value of 0.443068 and the cross-correlation value of 0.907426. 4D Inversion results reveal a change in the reflector at the reservoir zone, as indicated by the velocity pushdown caused for a decrease in seismic velocity owing to CO2. In addition, rock physics modeling provides that changes occur in bulk modulus, Vp, Vs, density, and AI. From the process, there are differences in AI values where the Inversion results show a decrease in AI values of 2.9%, while rock physics modeling shows a 12% reduction.

Abstract

Sleipner is the world's first commercial Carbon Capture and Storage (CCS) project, located off the coast of Norway, with the goal of reducing carbon emissions by capturing CO2 and storing it in a utsira saline aquifer sandstone reservoir capable of storing up to 600 billion tonnes of CO2. The CO2 injection in these projects increases year after year, so the CO2 development must be monitored to see the distribution pattern and its implications for the reservoir zone. The purpose of this research is to calculate and model the CO2 distribution resulting from acoustic impedance inversion using 4-dimensional inversion, to calculate the repeatability from seismic data between baseline and monitor using the Normalized Root Mean Square attribute. In the processing, baseline and monitor data must be matched in the overburden zone using a cross-equalization process so that the inversion process. The results revealed a correlation between the two seismic data sets (baseline and monitor) with the classification of Reasonable Repeatability, and CO2 distribution in a securely stored reservoir that spreads laterally and does not leak.

Abstract

Desa Cikakak di Sukabumi, Jawa Barat merupakan salah satu wilayah yang rawan gempa bumi dan tsunami. Untuk meminimalisir dampak bencana kepada masyarakat desa, dibutuhkan upaya pelatihan yang disebut IOWave23 agar mereka siap dan siaga jika terjadi kedaruratan. Pelatihan semacam ini perlu dilakukan secara berkala sebagaimana arahan Intergovernmental Oceanographic Commission (IOC), The United Nations Educational, Scientific and Cultural Organization) UNESCO. Terakhir diadakan 3 tahun lalu pada 2020 maka pelatihan harus disegerakan mengingat waktu ideal antar pelatihan adalah 2 tahun. Berkaca dari sejumlah bencana serupa di berbagai wilayah rawan di Indonesia maka kegiatan Pengabdian kepada Masyarakat (PkM) kali ini menjadi sangat penting karena memiliki tujuan utama memberikan pemahaman dan latihan langsung di lapangan terkait hal-hal yang harus dikuasai oleh masyarakat di wilayah rawan jika gempa bumi disertai tsuanmi melanda. Masyarakat terdampak perlu memahami hal-hal yang harus dilakukan saat terjadi bencana begitu juga setelahnya. Kegiatan utama pada PkM ini adalah drilling bencana beserta tindakan kesiapsiagaannya yang melibatkan ahli dan praktisi berpengalaman dari berbagai instansi seperti BMKG dan BPBD daerah. Target yang ingin dicapai dari program pelatihan ini peningkatan pengetahuan masyarakat Desa Cikakak mengenai kebencanaan gempa bumi dan tsunami, dan kesiapsiagaan menghadapinya.
