Khusna, Esti Ma'rufatul (2019) Analisis Variasi Tren Porositas dari Pseudoporosity Cube Berdasarkan Seismic Velocity dan Porosity Property Modeling pada Lapangan Est. Sarjana thesis, Universitas Brawijaya.
Abstract
Penelitian tren porositas ini dilaksanakan di Lapangan Est, yang merupakan salah satu lapangan gas di Area Mahakam. Penelitian ini bermaksud untuk membuat suatu pseudoporosity cube yang berguna untuk mendekati nilai porositas asli dari log. Metode yang digunakan dalam pembuatan pseudoporosity cube terdiri dari dua macam, yakni berdasarkan seismic velocity dan property modeling. Berdasarkan hasil yang dibuat, diketahui bahwa dari kedua model tersebut telah mendekati porositas asli dari log berdasarkan beberapa quality control yang telah dilakukan dengan standar deviasi perbedaan porositas log dengan model adalah berkisar 0,001 hingga 0,2. Kedepannya, kedua pseudoporosity cube tersebut dapat saling mendukung untuk merepresentasikan porositas semu di Lapangan Est. Berdasarkan pseudoporosity cube juga diketahui bahwa semakin besar nilai porositas model menunjukkan semakin besar nilai saturasi hidrokarbon dengan nilai koefisien korelasinya berkisar 80% hingga 93%. Selain itu, untuk menentukan area potensial Lapangan Est dapat dianalisis dengan menggunakan peta hydrocarbon pore volume/area. Area potensial dari Lapangan Est ditunjukkan dengan ketebalan reservoir hidrokarbon yang tinggi dan jumlah sumur produksi yang masih sedikit.
English Abstract
The porosity trend research was carried out at Est Field, which is one of the gas fields in the Mahakam Area. This study aims to create pseudoporosity cubes to approach the original porosity value. The method used for pseudoporosity cube building consists of two kinds, which are by seismic velocity and property modeling. Based on the results, it is known that these two models have approached the original porosity of the log by several quality controls that have been carried out with the deviation standard of the log porosity and the model is around 0.001 to 0.2. Going forward, these two pseudoporosity cubes can support each other to represent pseudo porosity in Est Field. Based on the pseudoporosity cube, it is also known that the greater the porosity value of the model also shows the greater the hydrocarbon saturation value with correlation coefficient ranging from 80% to 93%. In addition, to determine the potential area of Est Field can be analyzed using a map of hydrocarbon pore volume / area. The potential area of Est Field is indicated by the high hydrocarbon reservoir thickness and the number of production wells that are still sparse
