Exploratory drilling with core recovery.

The drill cores are samples of absolute representativeness of the subsoil for petrophysical, sedimentological, micro-paleontological, etc. analyzes allowing its analysis in the laboratory and offering reliable results of any lithology.

It consists of a drilling machine that uses a rotary drill of hollow cross section that allows to recover samples in cylindrical form of the subsoil, called drill cores or witnesses, these are taken at specific depths preserving its geological structure and its physicochemical characteristics.


The taking of drilling cores is usually necessary for the hydrogeological studies required by the National Service of Groundwater Irrigation and Drainage (SENARA) to determine the affectation of the hydric resource. They usually ask for a 20m deep drilling.

This type of drilling allows to determine locally the stratigraphy of the subsoil of the area of the project to be analyzed, especially where there is scarce information, to describe the lithological column, to report the levels of groundwater and to carry out tests of the soil layers.
