The Future is at the Bottom of the Ocean

Ocean bottom seismic has been gaining market share over high-end streamer acquisition. One of the ground-breaking technologies within acquisition is Magseis’ Marine Autonomous Seismic System Until recently, 90% of the…

The Golden Snitch?

Borehole Gravity for Reservoir Monitoring A shiny, one-inch round, miniature gravity meter is providing key bits of information about the distribution of pore fluids for reservoir monitoring. High-resolution borehole gravity…

Was the Mozambique Channel Once Scattered with Islands?

The geological history of the Davie Ridge tells us how tectonic, erosional and climatic forces shaped this part of the earth, pushing the mountains of west Madagascar, which once abutted…

Marine Seismic Data: Faster, Better, Cheaper?

New ideas in acquisition and processing are finally realizing the full potential of broadband data. Traditional towed streamer marine seismic acquisition has been stuck with the same old geometries for…

Khuff: A Major Reservoir

The Permo-Triassic Khuff reservoir is one of the most productive gas fields in the world. What are the factors which have helped it to become so prolific? Available online for…

An Overlooked Petroleum System

Is it possible to generate hydrocarbons over the oceanic crust? In petroleum exploration, the concept of hydrocarbon generation on the continental crust is completely accepted. However, modelling exercises demonstrate that,…

Gas Blowouts on the Yamal and Gydan Peninsulas

Last year a giant crater was discovered on the Yamal Peninsula south of the Kara Sea in the Russian Arctic, just 30 km south of the giant Bovanenkovo oil and…

Environmentally Friendly Seismic Source

eSource is a tunable, flexible seismic source which reduces the high frequency emissions that can affect marine life. Everyone working in the oil and gas industry is aware of the importance of…

Geophysics: A Simple Guide to Seismic Amplitudes and Detuning

Seismic amplitude changes may tell us something about reservoir lithology, porosity, and/or fluids. However, seismic tuning effects are potentially much larger than amplitude variations due to geological changes. Understanding this…

Little and Large

Seismic supply companies are helping operators face the downturn by providing cost-effective enhancements to existing product portfolios. With the oil price for this year staying at the low levels seen…

Vast Hydrocarbon Potential: Mexico’s Offshore Ronda Uno

An insight into some highlights of the offshore hydrocarbon potential available in almost virgin exploration territory. The Mexican Comisión Nacional de Hidrocarburos (CNH) announced its first ever licensing round (Ronda Uno) in…
