CoreAll is a Norwegian technology development company, working on the next generation core drilling solutions.
Core drilling, i.e. extracting continuous rock samples from the subsurface, is a central part of petroleum exploration drilling, providing essential information about the rock properties and the reservoir potential. This information is later used to determine drainage strategies and field development plans.
Although core drilling has been around for many decades, some challenges still remain. These include a noticeable lack of real-time information about the subsurface; considerable time lag between drilling of the geological formations and downhole logging of their properties; time-consuming round trips to change between core drilling and conventional drilling equipment; and insufficient control over formation fluid transformations and material loss as the core is extracted from the borehole. The CoreAll Intelligent Coring System addresses these shortcomings.
