| dc.description | The present project aims to reinterpret the Centenera 2 well logs, being focused mainly in the improvement
of the interpretation of porosities and other characteristics present in the formations. In order to complete
this objective, it has been developed a methodology that could be applicable to similar studies, especially
when old well logs are studied. The methodology begins with a process that consists on transforming the
original paper well logs into digital format well logs, so they can be treated by computer. Then, the digitized
well logs are corrected for well effects (temperature, diameter, mud density, etc.). Later, a general
interpretation of the well is made, subdividing it in several zones geologically different, for this way to
choose more economic interest zones. Finally a quantitative interpretation of the formations is carried out,
determining their porosities through different methods. The data obtained by the methodology, demonstrated
the existence of formations potentially producers of gas, the same ones that have bigger porosities to those
described by studies in past decades. | |
