Seismic
engineering is simply defined as a branch of
seismic
that focus not only to solve reservoir problems but also to solve engineering problems. This broad definition implies that geoscientists and engineer have to be collaborating each others. The first example of this
seismic
engineering is predicting pressure distribution in reservoir a dynamic property of reservoir. Pressure prediction from
seismic
data is useful not only in designing drilling program, but also useful for example in designing EOR programs to increase hydrocarbon recovery. Some companies run 4D
seismic
program in order to run EOR programs. Whit analyze this time lapse
seismic
data, some dynamic parameters of reservoir could be monitor.
The simple process of predicting pressure distribution for EOR programs mainly has three steps. First step is deriving pressure distribution from existing well at the objective layer. Second step is constructing seismic
attributes which related to pressure properties for that objective layer. And the final step is combining process of pressure distribution from well and
seismic
data.
The second example of this seismic
engineering are time to depth conversion (TDC). According to
seismic
engineering definition, TDC is also basic input for casing design and another well materials which dominated by engineer. Because of increasing need of
seismic
engineering, an intensive communication between geoscientists and engineer to fine tune this shift paradigm are needed. With sharp goals of
seismic
engineering, the main objective of upstream oil and gas company hopefully increase.
