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 ...

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 ...

Oilfield Technology | Peter Baillie | January

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 ...
