Broadband Seismic Technology and Beyond Part IV: PGS’s Geostreamer – Mission Impossible
In 2007, PGS took the industry by surprise with the launch of the GeoStreamer, the dual-sensor towed streamer that kick-started the broadband revolution. But how did they solve the riddle…
Polarising Pyrite
Norwegian company ORG Geophysical aims to find previously hidden hydrocarbon reservoirs by detecting shallow pyrite bodies using Induced Polarisation. In the second decade of the twenty-first century, competition for exploration targets is…
Completing the Picture
Enhancing the understanding of the Barents Sea with full-tensor-gravity gradiometry. The Barents Sea represents one of the largest areas of continental shelf on the globe and is a structurally complex region, composed of…
Think molecular. It translates into pay!
Petroleum source rocks can be formed in a variety of depositional environments. Key controls are organic matter production and preservation in the sediment. The organic matter deposited can be of…
Technology for Virtual Boreholes
Can a technology devised from space exploration help discover hydrocarbon resources? In the 1980s, Dr. Colin Stove, a researcher at the University of Aberdeen, Scotland, UK, was working on a…
Pressure Prediction in Exhumed Basins
Predicting pressure in basins that are exhumed or contain rich source rocks is difficult. We look at a case study from the Barents Sea region. The dominance of gas over…
Solutions for Monitoring Gas
In the face of widespread fears in the public about potential pollution as a result of fracking, we take a look at standards and best practices for environmental monitoring of…
Just How Good Are We at the Digital Oilfield?
We live in an age where phrases like ‘Integrated Operations’ and ‘Digital Oilfield’ have become part of our everyday parlance. But what do they really mean? Do these phrases mean…
Using Gravity to Enhance Recovery
4D gravity data is a very useful additional and independent source of information for monitoring reservoirs. Conceptual picture of water influx in reservoir during gas takeout. Water replacing gas in…
Hearing With Light!
Silixa’s intelligent Distributed Acoustic Sensor™ uses fibre optics to push the boundaries of seismic applications, as demonstrated through studies undertaken in Greece and the US. Most people are familiar with…
Shale Gas: Promises, Challenges and Global Implications
As is well known, shale gas and other unconventional resources have revolutionised the hydrocarbon industry in the US, and the country is expected to become a net exporter of gas…
