A 24-well pad is auto-planned and shows the Separation Rule anti-collision display computed for all wells all at once. The color controls represent three collision risk categories: green = minimum risk, yellow = medium risk and red = stop drilling, maximum risk zones. (Source ...
HOUSTON–Cuttings are a valuable and cost-effective source of subsurface data from both vertical and lateral wells that is commonly overlooked in oil and gas exploration and development drilling. Advancements in analytical technologies have enhanced the data extraction from cuttings to provide key subsurface insights ...
Evaluate Petroleum Systems to Identify New Exploration Opportunities
Over the past 35 years, geothermal projects have been developed in the Upper Rhine Graben (URG) to exploit deep geothermal energy. Underneath approximately 2 km of sedimentary deposits, the deep target consists of a granitic basement, which is highly fractured and hydrothermally altered. Therefore ...
The complex Central North Sea overburden, featuring shallow channels, contourites and injectites, presents a challenge for velocity modeling and often leads to distortions and difficulties in accurate depth placement of deeper targets.
Complex salt tectonics presents a key geological challenge in the Central North Sea. Salt flank and subsalt imaging has historically been a problem when evaluating complex stratigraphic traps.
Understanding reservoir quality and distribution is key to unlocking the remaining Paleogene potential in the Central North Sea.
A key challenge to unlocking the potential of Jurassic and Triassic reservoirs in the Central North Sea is the presence of artefacts and noise in seismic images. The presence of random noise, water-bottom and inter-bed multiples prevents accurate sub-BCU mapping and differentiation of the ...
The complex overburden in the Central North Sea region includes features such as shallow gas accumulations, contourites and channels. These represent potential drilling hazards and result in velocity and absorption (Q) anomalies that degrade the deeper image.
