Kristin – a tough lady
A deeply buried reservoir – characterised by ultrahigh pore pressures and temperatures – represent a major challenge for both petroleum and drilling engineers. To minimise risk and maximise the collaborative…

Planning software streamlines the decision process
Inconsistent methods used in the well planning process can result in erroneous decisions that have significant impact on field economics. By using a generic decision support tool, well projects can…
The same PRINCIPLE as in borehole logging
Reservoir rocks have much lower electrical conductivity if they are saturated with oil rather than salt water. This is the principle, well known from borehole logging, which is exploited in…
More geology with seismic velocities
Until recently, seismic velocities have had low value spin-off value as it was only used for migrating seismic data and depth stretching from time to depth domain in workstations. The…
Nimble Nodes
Tiny seismic nodes making high density land seismic accessible to all industries. Seismic acquisition has seldom seen such challenging times, especially onshore, where we are seeing tighter budgets and tougher…
The new UK National Data Repository: another milestone in accessing subsurface data
In 2015, when I carried out a small project that involved looking at composite logs from UKCS wells, I visited the OGA office near the Aberdeen railway station and spent…
New Life for Legacy Well Cuttings
There are millions of drill cuttings samples from thousands of oil and gas wells sitting unloved and under-utilised in warehouses and core repositories around the world, but there is now…
AI: a Game Changer in Seismic Acquisition and Processing
Leveraging artificial intelligence to improve efficiency, predictability and performance in seismic acquisition and processing. A recent Gartner seminar made the bold prediction that “in the near-term AI will not replace…
How Machine Learning is Helping Seismic Structural Interpreters in The Age of Big Data
This seismic fault interpretation workflow integrates geological knowledge, machine learning (ML) and deterministic techniques aimed at mapping and characterizing a fault framework with geological consistency. The availability of large 3D…
Ocean Bottom Seismic: Robots on the Seabed
Will automation in ocean bottom seismic revolutionise operations and cut costs? It is generally accepted within the seismic acquisition industry that seabed seismic receivers deliver superior seismic data and consequently…
Greater Castberg: Seismic challenges in the High North
“We are hoping for many discoveries in the Greater Castberg area in the years to come”, said Hossein Mehdi Zadeh, Principal Geophysicist at Equinor during the NCS Exploration – Recent…
Vintage Maps Reborn
Using 3D animation software and surface models for new hillshade mapping techniques to produce hyper-realistic 3D-like maps. A new trend of map-making has recently evolved and changed the way we…
