CCED is the operator of onshore blocks in the Sultanate of Oman. The blocks are located on the eastern flank of the Oman Salt Basin. Within the area of interest, the Barik, Al Bashair, Buah and Khufai Formations form the main oil and gas ...

Tables are ubiquitous in the geoscience industry, appearing in numerous documents and spreadsheets. They contain a wealth of data in a structured format which can help us understand the subsurface. However, the number of tables created over the years is huge and it requires ...

Novel/Additive Information: The paper presents a simple and computational fast method to predict CO2 injectivity and well pressure as a function of time. The application of superposition in time - a method usually associated with solving linear problems - is demonstrated to adequately solve ...

Up-down deconvolution remains a powerful tool for the processing of ocean-bottom node data through its ability to efficiently attenuate free-surface multiples along with the source ghost and signature. Practical receiver-domain implementations in the frequency-wavenumber domain, however, assume layer-cake geology and can leave residual multiples ...

CGG has undertaken a multi-phase, multi-year data enhancement and acquisition project, commencing with a major basin-scale reprocessing initiative (ReGeneration) and culminating in the completion of a new 3D acquisition and imaging project, completed in 2021. The new survey has provided expanded data coverage from ...

Seismic imaging in the Kwanza Basin has historically proven to be challenging owing to its complex geology and the presence of deep pre-salt targets. CGG has recently re-imaged its Kwanza Basin multi-client data portfolio to benefit from new insights made possible by advanced proprietary ...

A continuing concern regarding presalt carbonate reservoirs offshore Brazil is how to derive accurate quantitative estimates of reservoir properties. It is challenging to understand the link between the facies model and the variation in elastic properties, recover a reliable model of elastic properties from ...

Short-period multiple attenuation is often challenging as the multiple generators are typically not sufficiently well recorded as primary events for SRME to be successful. Model-based approaches have traditionally been used to circumvent this problem but may only model multiples generated by key events such ...

This study is concerned with testing the application of Automated Mineralogy (AM), specifically QEMSCAN, to identify and quantify microplastic particles within a solid heterogeneous specimen, as an initial assessment of how this technique may be utilised in microplastic research and environmental monitoring. It utilises ...
