ABSTRAK Metode logging dapat mengetahui dan menilai sifat fisis batuan-batuan yang mengelilingi lubang bor tersebut. Metode ini juga dapat memberikan keterangan kedalaman lapisan yang mengandung hidrokarbon serta sejauh mana penyebaran hidrokarbon pada suatu lapisan. Interpretasi data log digunakan untuk menentukan fluida pengisi dengan analisa kualitatif guna menentukan volume shale (Vshl), porositas (Phi), resistivity water (Rw), dan saturasi air (Sw) pada 13 data sumur “TG”. Selanjutnya menetukan preoperti petrofisika sebagai langkah melakukan karakterisasi data sumur yakni menentukan volume shale menggunakan metode gamma ray indeks, menentukan water resistivity menggunakan metode korelasi log Rt, menentukan porositas menggunakan korelasi log density & neutron, dan untuk menentukan saturasi air menggunakan metode simandoux. Berdasarkan analisa 13 data sumur “TG”, Lapangan “RM” memiliki fluida pengisi berupa minyak dan air. Nilai porositas rat-rata pada lapangan “RM” adalah 18% dengan nilai rata-rata saturasi minyak adalah 42.15%, Adapun ketebalan formasi target lapangan “RM” memiliki variasi antara 300 meter hingga 550 meter, sedangakan ketebalan reservoar berkisar antara 90 meter hingga 250 meter. Lapangan “RM” memiliki cadangan minyak awal sebesar 17.67 Juta Barrels. ABSTRACT Logging Methods can identified and predicted the rocks which surrounding the borehole. This method also give the information of depth of layer which contains hydrocarbon and the extent of the hydrocarbon spreading in the layer. Log’s interpretation used to determineed fluid contents with qualitative to defined volume shale (Vshl), porosity (Ф), resistivity water (Rw), dan saturation water (Sw) in 13 of “TG” well data “RM” field. Furthermore, as a step to determine preoperti petrophysical well data to characterize that determine the shale volume used gamma ray index method, determine water resistivity with Rt correlation, determine the porosity used density and neutron log correlation and to determine water saturation used simmandoux approach. Based on the analysis of 13 wells "TG" Field "RM" has a fluid filler such as oil and water. Porosity The mean on the ground "RM" is 18% with an average oil saturation is 42.15%, The thickness of the formation of the target field "RM" has a variation of between 300 meters to 550 meters, while the thickness of the reservoir ranging from 90 meters to 250 meter. Field "RM" has initial oil reserves amounted to 17.67 Million Barrels. Keywords : Logging, Hydrocarbon, Porosity, Oil Saturation, Reserves.
