Abstract
ND Field is a mature field, whose production has decreased. This field has considerable hydrocarbon potential. With such a large potential, it is possible that in reservoir x which is in the Telisa Formation there is still the potential for hydrocarbons in the un-drainage area outside the area of the producing wells. The reservoir x compartmentalization analysis is carried out using the fault seal analysis method, mapping the reservoir x property combined with the analysis of pressure data between compartments. Reservoir x, production and pressure data are used to analyse the amount of connected gas in place (CGIP) using the P/Z method. Reservoir x connectivity is divided into 4 compartments. CGIP volume analysis using the P/Z method shows CGIP compartment 1 of 1400 MMSCF and for compartment 2 of 350 MMSCF, whereas with volumetric it is found that compartment 3 inplace is 261.4 MMSCF and compartment 4 is 413.9 MMSCF.
