Abstract

Minyak dan gas bumi merupakan hasil endapan selama bertahun-tahun dari senyawa organik yang pernah hidup. Pengelolaan minyak dan gas bumi memerlukan beberapa proses, salah satunya yaitu melalui interpretasi data sumur dan data seismik untuk memahami struktur geologi bawah permukaan. Metode yang sering digunakan sebelumnya dalam memahami struktur geologi bawah permukaan, yaitu dengan melakukan analisis integrasi data well log dan data seismik 2D. Pada penelitian ini pendekatan metode yang dilakukan, yaitu dengan mengembangkan model penampang dengan membuat integrasi antara data well log dan data seismik 3D untuk menghasilkan penampang fasies pada daerah penelitian. Pemanfatan data seismik 3D dalam mengidentifikasi fasies dapat menunjukkan distribusi fasies secara vertikal dan horizontal untuk identifikasi lingkungan pengendapan dan menjadi informasi penting dalam karakterisasi reservoir sehingga memudahkan peneliti dalam pengambilan keputusan pengembangan kelola sumber daya lapangan. Penggunaan metode integrasi data seismik 3D dan data well log pada penelitian ini menghasilkan model penampang fasies yang dianalisis untuk identifikasi lingkungan pengemdapan dan terbukti dapat menunjukkan sebaran litofasies pada bawah permukaan lapangan minyak dan gas bumi. Model penampang fasies pada lokasi penelitian di kawasan laut utara Belanda menurut penelitian ini menunjukkan sebaran fasies Shalestone terdapat di sisi timur lapangan penelitian yang mengindikasikan arah pengendapan ke timur, sedangkan untuk fasies Sandstone terlihat menebal dari sisi timur ke barat lapangan penelitian. Lingkungan pengendapan Blok F3 Laut Utara Belanda adalah marine, dengan fasies offshore transition mid shelf. Model penampang fasies yang didapatkan menunjukkan bahwa pengembangan dapat dilakukan lebih lanjut dengan berfokus pada sisi barat lapangan penelitian.

Oil and natural gas are the result of years of sedimentation from organic compounds that once lived. Oil and natural gas management requires several processes, one of which is through the interpretation of well data and seismic data to understand the subsurface geological structure. The method that is often used previously in understanding the subsurface geological structure is by conducting an integrated analysis of well log data and 2D seismic data. In this study, the method approach used was to develop a cross-section model by integrating well log data and 3D seismic data to produce a facies cross-section in the research area. The use of 3D seismic data in analyzing facies can show the distribution of facies vertical and horizontal to identify the depositional environment and become important information in reservoir characterization, making it easier for researchers to make decisions about developing field resource management. The use of the 3D seismic data integration method and well log data in this study resulted in a facies cross-section model that was analyzed to identify the depositional environment and was proven to be able to show the distribution of lithofacies in the subsurface of oil and gas fields. The fasies cross-section model at the research location in the North Sea area of the Netherlands according to this study shows that the distribution of Shalestone facies is on the east side of the research field wgich indicates the direction of deposition to the east, while the Sandstone facies is seen to thicken from the east to the west side of the research field. The depositional environment of Blok F3 of the Dutch North Sea is marine, with offshore transition mid-shelf facies. The facies cross-section model obtained shows that further development can be carried out by focusing on the west side of the research field.
