Reservoir simulation models are used to forecast future reservoir behavior and to optimally
manage reservoir production. These models require specification of hundreds of thousands …

Seismic data are increasingly required to be high quality for the continuous improvement of
the degree of exploration. From the viewpoint of inversion, the utilization of more information …

To mitigate the global warming crisis, one of the effective ways is to capture CO2 at an
emitting source and inject it underground in saline aquifers, depleted oil and gas reservoirs …

A sequential inversion methodology for combining geophysical data types of different
resolutions is developed and applied to monitoring of large-scale CO 2 injection. The …

Despite over twenty years of research and application, assisted seismic history matching
(ASHM) remains a challenging problem for the energy industry. ASHM attempts to optimise …

This study aims to develop a methodology for calibrating subsurface stress changes through
time‐lapse vertical seismic profiling (VSP) integration. The selected study site is a region …

Four-dimensional seismic analysis is an effective reservoir surveillance tool to track the
changes of fluid and pressure phases in the oil and gas reservoirs over time of the baseline …

Abstract For many decades, Enhanced Oil Recovery (EOR) scheme has been initiated to
improve recovery factor for various oil and gas fields worldwide and Malaysian basins also …

Abstract 4D seismic surveys are now routinely used to monitor hydrocarbon reservoirs.
Because seismic reflections are sensitive to formation stress and fluid content, repeated …

The conventional method of time-lapse AVO (Amplitude Versus Offset) inversion is mainly
based on the approximate expression of Zoeppritz equations. Though the approximate …
