Did you know that rocks have memory?
The seismic signature of a sedimentary rock is strongly influenced by the geological history of the rock, e.g., the depositional environment, whether it has experienced tectonic burial and uplift, etc. Read More
Half full or half empty
“Oil major ExxonMobil bets that through technological advances, shale producers can manage to double crude output from their existing wells.” That was one of the headlines from an article published Read More
Production allocation and fluid fingerprinting in conventional reservoirs
Geochemical fingerprinting for production allocation of oil, gas or water is a well-established workflow in conventional reservoirs for both subsurface and topside facilities applications. These methodologies have been in existence Read More

Rapid and long-lasting sealing of bedrock using concretion-forming resin
Wells and underground excavations typically require effective permanent sealing when they have fulfilled their intended functions. Abandonment of hydrocarbon production or CO₂ injection wells or sealing of underground waste repositories are Read More
De-risking gas saturation
Conventional workflows such as near versus far amplitudes or linear inversions often fail to differentiate between low and high-saturation gas reservoirs, mainly due to the relative lack of sensitivity to Read More
A passion for the product
“My best tip for salespeople new to the job is to establish long-term relationships with clients. Let them know you will go the extra mile and show them a passion Read More
Natural fracture networks are not created equal
Natural fracture networks are not created equal. In a tight reservoir, they may enhance the permeability and give production an upside. In a porous reservoir, a natural fracture network may Read More
A new hydrogen play
Exploration for geologically occurring hydrogen is taking off worldwide. In May, FDE announced a serendipitous discovery of hydrogen whilst drilling for coalbed methane in the Lorraine region in France. In Read More
