Australia: Santos Building Reserves

Although not tested, Santos has claimed its Lasseter 1 wildcat in WA-274-P in the Browse Basin off Western Australia as a significant gas/condensate discovery. The well, located in 404m of water, was targeting Read More

Argentina: Significant Reserves Below Las Mesetas

YPF has made what it describes as the largest conventional gas/condensate discovery in the province of Santa Cruz in the last 20 years by drilling beneath already mature formations in Read More

Malaysia: Second Deepwater Gas Find

For the second time in 2014 Shell has confirmed a deepwater gas discovery in Block SK318 offshore Sarawak, results that are seen as very positive indicators for the gas potential of the area. The Read More

A Beautiful Country – The Geology of Lebanon

This book is in large format, making it suitable for presenting text along with photos and maps. The list of contents includes eight chapters, references, index and author’s biography, but lacks a list of figures. Read More

The Quantification of Uncertainty in Reservoir Management

New developments in history matching improve uncertainty quantification and risk assessment in reservoir management. Improving the analysis of risk in field management is the Holy Grail of reservoir modelling and in Read More

Making an Educated Guess

An online game shows that using input from a knowledgeable crowd can lead to better decisions. In a recent experiment, university students and oil industry staff, including non-explorationists, tried to predict whether exploration Read More

Sergipe Basin, Brazil: DHIs from calibrated AVO stacks

AVO signatures help identify hydrocarbons In the relatively mature Sergipe Basin, AVO anomalies can be used to highlight prospective anomalies and eliminate leads and prospects without such indicators. The Sergipe Read More

Scotland Decides

The issue of Scottish independence has divided a nation – and worried an industry. Since oil was first discovered in the cold, stormy waters of the UK North Sea, people in Read More

Broadband Seismic Technology and Beyond PART XI: Which Technology to Choose?

Using the Utsira High as a field laboratory for broadband testing. The answer, my friend, is hiding in the waves, the answer is hiding in the waves (with apologies to Bob Dylan, and thanks to Read More

Offshore and Deepwater Challenges Remain

The Minister of State at the Department of Communications, Energy and Natural Resources opened the 2015 Atlantic Margin Licensing Round on 18 June 2014 advising that applications for Licensing Options are to Read More

The Power of Movement

Kinematic modelling and analysis unlock many secrets of geological systems, providing a structurally valid framework for further analysis and risk assessment, ultimately reducing uncertainty in hydrocarbon exploration and production. Timing Read More

The Search for Oil in the South-Eastern Barents Sea

Broadband imaging improves the understanding of a prospective area on the Finnmark platform. For more than 40 years Russia and Norway were in dispute over a 175,000 km2 area in the Read More

Western Tanzania: The Lake Rukwa and Lake Nyasa Rifts

Independent explorer Heritage Oil focuses on regions which may have been overlooked and where it can participate as an early entrant. We look at its exploration efforts in two blocks Read More

Inside the Rock

For the first time, geoscientists can produce 3D images of rock features at a wide range of scales – from millimetre through micron and down to nanometre size – and Read More

The Deepwater Niger Delta: An Underexplored World-Class Petroleum Province

The Niger Delta system (Figure 1) is one of the world’s largest Tertiary deltas and one of its most prolific hydrocarbon systems, containing an estimated 68 Bboe and producing approximately 3 MMboe per Read More
