Abstract:
Abstract. The Los Humeros geothermal system is steam dominated and
currently under exploration with 65 wells (23 producing). Having
temperatures above 380 ∘C, the system is characterized as a super
hot geothermal system (SHGS). The development of such systems is still
challenging due to the high temperatures and aggressive reservoir fluids
which lead to corrosion and scaling problems. The geothermal system in
Acoculco (Puebla, Mexico; so far only explored via two exploration wells) is
characterized by temperatures of approximately 300 ∘C at a depth
of about 2 km. In both wells no geothermal fluids were found, even though a
well-developed fracture network exists. Therefore, it is planned to develop
an enhanced geothermal system (EGS). For better reservoir understanding and prospective modeling, extensive
geological, geochemical, geophysical and technical investigations are
performed within the scope of the GEMex project. Outcrop analogue studies
have been carried out in order to identify the main fracture pattern,
geometry and distribution of geological units in the area and to
characterize all key units from the basement to the cap rock regarding
petro- and thermo-physical rock properties and mineralogy. Ongoing
investigations aim to identify geological and structural heterogeneities on
different scales to enable a more reliable prediction of reservoir
properties. Beside geological investigations, physical properties of the
reservoir fluids are determined to improve the understanding of the
hydrochemical processes in the reservoir and the fluid-rock interactions,
which affect the reservoir rock properties.
