Working Petroleum Systems Offshore Montenegro

Evidence for working petroleum systems offshore Montenegro as new geochemical information reveals the presence of an oil-prone Late Jurassic–Early Cretaceous source rock on The Dalmatian platform. The Dalmatian platform offshore…

Geomicrobial Exploration

Microbial magic: how medical DNA fingerprinting can de-risk hydrocarbon exploration and production. Geomicrobial exploration is a novel technique within geochemical exploration. It uses the same base principle of detecting a…

What is Chemostratigraphy?

Chemostratigraphy has evolved and grown from a niche, often misunderstood, speciality into a comprehensive, inclusive, game-changing technology that delivers real insight in oil and gas exploration. The rapid expansion of…

The Origin of Shale Gases

The origin of shale gases has important implications on their ability to provide hydrocarbon reserves. As we all know, the discovery that gas formed and locked in shale source rocks…

High-Res Characterisation of Unconventional Reservoirs

GEOLOG has developed an innovative workflow, integrating wellsite activity with laboratory work to define a comprehensive, high-resolution understanding of unconventional reservoir properties. © GEOLOG. Unconventional activities constantly require new technological…

Reservoir Rock Characterisation Using Raman Spectroscopy

Raman Spectroscopy enables precise reservoir rock characterisation studies and provides invaluable insight into the reservoir’s heterogeneity and other fine-scaled details. In today’s competitive market, reservoir rock characterisation has become a…

Wellsite Mud Logging and Reservoir Geochemistry

Wellsite mud logging and reservoir geochemistry results in a better reservoir characterisation in real time, improving performance and reducing costs. The Evolution of Geochemistry A mud logging-geochemical unit operating in…

Exploration Geochemistry in the Digital Age

The companies that lead the next wave of exploration will be those that concentrate their time on analysis and not on data acquisition. Oil and gas exploration is experiencing revolutionary…

A Light in the Downturn

Geochemical innovation for today’s explorers In today’s hardscrabble upstream economy, meager analytical budgets are the rule even among E&P companies with a strong scientific focus. When only ‘necessary’ analyses are…

The Geochemist’s Tool Box

The conjugate petroleum systems of the North Atlantic, finding hydrocarbons and developing the assets – all viewed through the oil-stained spectacles of geochemistry. The North Atlantic region has seen some…

The Dark Horse Upstream

In 2008, Petrohawk of Houston made the now historic Texas Eagle Ford shale discovery after consulting geochemical data from a nearly forgotten 50-year-old wellbore. The basic 1950s geochemistry confirmed sufficient…
