The entries represent the raw We have developed a "4D seismic technical risk information at a reservoir and field site that is needed to spreadsheet" as a quantitative tool to help decide whether determine the probability of success for a 4D seismic it is technically advisable to perform a time-lapse 4D project. The following descriptions help clarify some of seismic monitoring project for a specific reservoir and the entry data needed for the 4D Fact Sheet.

The characterization of method are more efficient for Seismic wave impedance inversion method has more calculation. Before inversion, using deconvolution, progress in the decade, especially predicting seismic velocity and phase analysis, that will be very reservoir bed and delineate seismic reservoir important.

Several significant events have taken place recently in the Natuna Sea, the most important being the The purpose of this paper is to provide a modern development project approval for the super-giant East regional geological and geophysical interpretation of Natuna Gas Field which has recoverable reserves of the entire Natuna Sea Region covering two of the 45 TCF of methane gas. In the West Natuna Basin, largest producing areas of Indonesia, both of which recent activity has been fast paced with consolidation retains considerable exploratory potential. The basis of several new development and exploration projects, for this seismic interpretation are 4,500 kilometers of in particular the ongoing oil field development of the recently acquired non-exclusive seismic data. This KRA Field in the Kakap Area, the gas project at the 1995 vintage Natuna seismic survey consisted of Anoa Field and drilling of new exploratory plays.

The present activities are dominated by 2D, 3D and 4D seismic Most Indonesian oil and gas have been found in the Tertiary methods including their integration of reservoir sedimentary sequence. A new objective, the Pre-Tertiary characterization in Western Indonesia, and by 2D seismic in prospects, emerged recently and were encouraged by the Eastern. In response to the natural decline of oil production discovery of hydrocarbons in Eastern Indonesia and Papua in the future, efforts with integrated geophysical methods are Guinea (Nayoan et all., 1991), and in the Timor sea expected to be intensively used in many of producing areas (Puspoputro, 1995). of Western Indonesia, whereas more regionally oriented geophysical methods are expected in the frontier exploration About seven decades ago geophysical methods were firstly of Eastern Indonesia. Exploration opportunities in Eastern used in oil exploration in the tropical jungle of Sumatra and Indonesia are of high risk but promising prospects.

The E-BD oil and E-CE oil and gas fields are located in Large parts of these reservoirs are close to or below tuning the western portion of the Bredasdorp Basin offshore thickness and various geophysical techniques have been South Africa (Fig 1). Here the water depth is 100m and applied in this study in an effort to determine the field geometries. Seismic attribute mapping (particularly amplitude responses), seismic correlation, seismic inversion and an AVO processing method have been applied to the 3D data volume over these fields. This study evaluates these various techniques for determining sandstone distribution.

The effect of ground coupling can The large amount of information carried by the seismic be ignored as long as the geophones are planted in signal is available fully for interpretation only if firm soil, since coupling resonance is much higher the geophones follow the movement of ground faithfully than the normal seismic frequency band of 10-l 50 with minimal distortion. This implies that the bandwidth Hz. for reflection survey. In loose and unconsolidated of transfer function of the geophone and the ground soil, coupling resonance falls well within the seismic must be as large as possible. This transfer of movement frequency band resulting in distortion of the signal. of soil to the geophone is known as geophone ground Highly variable surface conditions in Ramnad subbasin coupling. In addition to various factors such as the of Cauvery basin in India severely affect the responses of source, earth,individual geophones, geophone seismic data quality. This has necessitated the need and source arrays and instruments; geophone ground to study the effect of geophone ground coupling in coupling also drastically changes the signal to noise this area. Seismic data was acquired at different locations spectral bandwidth resulting in poor data quality.
