Unconventional shale reservoirs have gained significant attention in recent years in terms of hydrocarbon reserves and production potential. However, exploration and production from shale reservoirs are still very challenging. ...

Synthetic study has proved that post-stack Structural Filter (SF) applied to Common Offset (CO) gathers with pilot-stack showed better performance over FK Dip Filter and FX Decon with regard to fault preservation, noise ...

Apparent attenuation resulting from interbed multiples is conveniently expressed by Margrave’s nonstationary convolution model. A few examples of nonstationary processes are time migration, normal-moveout corrections, and ...

Pore pressure prediction provides an important risk assessment in the oil and gas industry. It is widely used to estimate the seal integrity, reservoir pressure compartmentalization, hydrocarbon column height, and to design ...

Reflections from the top and bottom of beds thinner than λ/4 cannot be distinguished from one another due to the limit of seismic resolution. It would be advantageous for geoscientists to image thin beds below resolution, ...

The near-surface of the Earth often has rapidly varying velocity changes that distort the seismic images to a greater or lesser degree. Depending on the complexity of the velocity variations, a variety of methods have ...

The waveforms generated during hydraulic fracturing in unconventional oil and gas reservoirs contain information about the nature of the failures that gave rise to the observed wave fields. Inverting for the moment tensor ...

The fundamental parameters in seismic reservoir characterization are P-wave, S-wave velocities, and density. Understanding the relation of these parameters with the pore-fluid content and lithology is the key for this ...

In recent years the Oil & Gas Industry has been searching for new technologies to increase 3D seismic resolution and fracture detection for shale unconventional reservoirs. Since most shale reservoirs are thin-layered and ...

Seismic amplitude study is a crucial aspect in reservoir characterization as it helps to analyze seismic responses before interpretation. In this study, an attempt was made to identifying the reservoirs present in the High ...
