Abstract

Seismic inversion method is one method to describe and physical parameters of mengestimasi beneath the surface in the form of impedance values by using data well as control and seismic data as input data. The purpose of doing research this time is determining the character of value-based acoustic impedance reservoar obtained from the process of inversion layer at the target age of Early Pliocene to Middle Miocene epochs. Research on the data there is 1 data i.e. Wells MD-1 and 2D seismic data Post Stack Time Migration. Methods of analysis used is doing a comparison of the results of seismic cross-section of 3 methods of seismic inversion, i.e. a Model Based, Band Limited, and Sparse Spike to get a layer of hydrocarbon prospects. Research on hydrocarbon targets this time reservoar gas contained in carbonate. Through the analysis of three methods of inversion results showed a good correlation between seismic trace inversion with synthetic that generates e < e0. After a comparison of the results of seismic cross-section and pre-analysis method of inversion is the best to use is a method of interpretation Model Based, due to the results of a cross section of support as well as the value of a small error and correlation fit (Fitting). The results of the inversion is done by data Fitting well and produced a layer of the appropriate prospects in Late Miocene epochs – Middle Miocene epochs that have Carbonate litologi Tight.
