Abstract

Petrophysics analysis conducted to evaluate petrophysical parameter on “DMA” Formation. Porosity identification, shale content, water saturationand permeabilityconducted on two well that is DMA-01 and DMA-04.Shale content estimation conducted using Gamma Ray log, effective porosity estimation conducted using both of density log and neutron log,water saturation calculated using Archie equation, and permeability calculated using Schlumberger and Timur equation. Based on petrophysics analysis using Interactive Petrophysics software, reservoir largely filled by fluid that is gasfor DMA-01 and oil for DMA-04, with petrophysics property values on DMA-01 for Vshale 0.048-0.2753, porosity 0.0889-0.2522, Water Saturation (Sw) 0.34-0.6842 and for oilpetrophysics property valuesVshale 0.078-0.03197, porosity 0.0761-0.2668, and Water Saturation (Sw) that is 0.22-0.64, and permeability value on each well is 0.35-7885.22 mD, and 0.1532-1769.62 mD.Furthermore, conducted lumping using cut-off value as follows for DMA-01 is VShale ≤ 27,53%, PHIE ≥ 8 %, SW≤ 68,42 %, Permeability ≥ 1mD and for DMA-04 is VShale ≤ 31,97%, PHIE ≥ 7,6 %, SW≤ 64 %, Permeability ≥ 1mD. Hydrocarbons reserve on two research wells estimated. Reserve calculation on petrophysics parameter using Probability method. Gas reserve calculation result amount 42.17 BCFG and for oil reserve is 25.09 MMOB.
