We describe opportunities and challenges for imaging seismic data acquired using conventional marine sources and receivers located on the seafloor. Opportunities include the promise of greater imaging resolution than sea-surface acquisition and processing can offer, especially using P-wave to S-wave converted reflection energy (PS ...

A gas field, China, the target reservoirs are mainly delta front depositions, which are tight, thin, and below the tuning thickness. In order to charaterize the thin effective reservoir and porosity distribution in this field, a geostatistical inversion and co-simulation were performed. Using geostatistical ...

In this paper, we described some of the key challenges faced and their solutions during the reservoir characterization study. Shear log prediction can be done quickly by methods, such as multi linear regression and also by building a robust petro-elastic model, if pore geometry ...

Seismic Reservoir Characterization is a well-known technique to obtain a better understanding of hydrocarbon-bearing reservoirs by careful analysis and integration of petrophysical and seismic data. The petrophysical properties are normally obtained through the evaluation of well logs and core data. A rock physics model ...

In this paper, we present a UK case study and draw on lessons learnt from the American market by using mineralogical and textural data obtained by AM and measured TOC to constrain and improve the accuracy of petrophysical modelling. We characterize a UK unconventional ...

By adapting reverse time migration (RTM) and demigration as the migration and modeling operators to maximize the crosscorrelation between the simulated and the acquired seismic data, we introduced a new practical least-squares RTM (LSRTM) scheme and derived a steepest descent method in seeking the ...

In this paper, we propose an adaptive implementation scheme for first separating multiples from primary events by a given multiple model in seismic data and subsequently removing the multiples from noisy seismic data using the curvelet transform. Due to the sparseness of seismic data ...

The Banda Arc is of great interest to petroleum explorers because of abundant onshore and offshore oil and gas seeps and similarities with geologically contiguous Mesozoic and Cenozoic successions in Australia where numerous petroleum systems exist and have been exploited (the Mesozoic basins are ...
