Christensen Roder owns a complete line of core bits and pipes for removing cores, foreseen to operate in the most diverse formations.

We have a background experience which surpasses 20 years in service, with a recovery core average above 92%, making us leaders in the area.

This service mainly consists in the removal of conventional cores, or oriented cores in advanced or exploration drilling wells, where we provide a full service, both in ground operations as in platforms (Off Shore), within and out of the country, and it ends with the delivery of the core at its respective box, labeled and in good condition.

The main object when coring is always the core integrity. Good cores allow to obtain a series of information on the area of interest. By good cores, we make reference to those reflecting, in the most original manner, the conditions of the formations of the tested area. Present techniques on core evaluation provide critical information to foretell and direct the production of a mineral.

The second aim when coring is reducing the most the cost of tested meter.
Therefore, it is necessary to keep the recovery indexes near a 100% y to use work parameters that produce high penetration rates and maintain long life of core bits and equipment.
Equipments that reduce maneuver times for the removal of cores, also contribute to this aim.
