Drawing up an Integral Plan for the Control of Floods and Mass Movements to achieve the desired levels of protection and safety by reducing the risk of disasters caused by floods and mass movements at pre-investment level in the Casma and Mala basins.

Assistance for the design of river defences in the Lacramarca and Viru basins.

Geological risks: Identification and characterisation of geological risks associated with floods and mass movements in the Casma, Lacramarca, Piura and Viru river basins at pre-investment and design stages, including: remote sensing analysis, flood event mapping, historical orthophoto analysis, geological hazard mapping, vulnerability analysis, geological risk mapping and cost-benefit analysis.

Geotechnics: design and execution of geological and geotechnical characterisation campaigns for the design and construction of flood and mass movement protection in the framework of reconstruction with changes from the 2017 FEN for several basins in Peru. The work included the execution and interpretation of refraction seismic tests, SEV, MASW, calicatas and slope stability in the sections of rivers and streams where the projection works are projected against the geological risks of flooding and debris flow (landslides).

CHARACTERIZATION OF THE INTERRELATIONSHIPS BETWEEN SURFACE WATER AND GROUNDWATER

Catalonia, SPAIN. Agencia Catalana del Agua 2020.

Study of the relationship between surface and groundwater bodies for the control and protection of wetlands, riverbeds and springs through the analysis of rainfall series, piezometric evolution, phoronomic evolution, hydrochemistry, hydrometeorological balance of aquifer systems, definition of upwelling conceptual models, and updating the river-aquifer relationship models.

The study included extensive fieldwork in the inland basins of Catalonia in which an inventory of water points, wetlands and riverbeds was updated, identifying possible conditions, water sampling and local geological and environmental characterization

UPDATE OF THE CONCEPTUAL HYDROGEOLOGICAL MODEL OF THE OLLACHEA TUNNEL

Ollachea, Carabaya, PERU. Intersur Concesiones S.L. - Ministerio de Transportes y Comunicaciones 2019-2021.

Update of the conceptual hydrogeological model of the Ollachea Tunnel route, including the analysis of the fracturing of the rock massif, possible interactions with the tunnel layout, and proposal of a control network.

STUDY AND HYDROGEOLOGICAL MONITORING OF THE SUBSECTION: ARANJUEZ-ONTÍGOLA OF THE EAST HIGH-SPEED TRAIN "AVE" LINE

Madrid-Toledo, SPAIN. ADIF 2018.

Conducting the hydrogeological study and monitoring of the area around the El Regajal tunnel on the East High Speed Line, which serves as a basis for documenting all hydrogeological studies conducted and data gathered during the planning and construction phase, and thus, having an understanding of the hydrogeological operation of the route’s environment 5 years after the commissioning of the line.

CAES PROJECT PHASE II – SELECTION OF GEOLOGICAL FORMATIONS/STRUCTURES CAPABLE OF STORING COMPRESSED AIR FOR THE IMPLEMENTATION OF CAES TECHNOLOGY IN SPAIN

SPAIN. Ministerio de Transición Ecológica 2013

Selection of geological structures in Spain that are most suitable for underground energy storage using CAES technology. It is based on a preliminary pre-selection study, also carried out by AIRTIFICIAL (Phase I) and aims to reach the identification and detailed study of a minimum of favorable structures for CAES. For this selection, technical (design) indications of the Customer and their preferred areas of location are taken into account.

ESTUDIO Y MONITOREO HIDROGEOLÓGICO DEL CAMPO MARGARITA

Tarija, Bolivia. REPSOL 2017-2023

The Margarita hydrocarbon field is considered to be in an area with low rainfall where, despite this, there have never been any supply issues, even at peak consumption.

A comprehensive hydrogeological study was carried out including: Characterization of the aquifer system (aquifer formations, geometry, relationship between formations), water balance, piezometric control network, quality control network and phoronomic control network, and a mathematical model, resulting in a complete characterization of the quantitative and qualitative status of the Huacaya-Palos Blancos Myoquaternary Aquifer.

Subsequently, a monitoring campaign of the control networks established in the Hydrogeological Study and an update of the numerical model were carried out.

GEOLOGICAL, HYDROGEOLOGICAL AND SEISMIC STUDY. RESEARCH SURVEY IN VALDEPRADO DEL RÍO (CANTABRIA)

Cantabria, España. Petroleum Oil & Gas España S.A. 2015.

The purpose of this study was to deepen the geological and hydrogeological knowledge of the environment of the stratigraphic research wells BB1 to BB8 that Petroleum Oil & Gas España S.A. intends to drill to study the different formations of the subsoil and obtain a detailed geological characterization.

GEOLOGICAL, HYDROGEOLOGICAL AND SEISMIC STUDY. El COTO-2 AND CADIALSO-2 RESEARCH SURVEYS

Tajo Bassin, España. IGME 2012.

The El Coto-2 and Cadialso-2 research wells are drilled to research the various subsurface formations and obtain a geological, geochemical, geomechanical and petrophysical classification. Similarly, the purpose of these wells is to conduct conventional and unconventional production tests through hydraulic fracturing to assess the potential as a non-conventional gas reservoir of the Lower and Middle Jurassic marls formations. They are deviated-type exploratory probes with a horizontal cross-section when reaching the target formation. The final depth of the wells varies from 3,700 m foreseen for El Coto-2 to 3,950 m at Cadialso-2.

In general, the following aspects are considered: Geological Study; Hydrogeological Study; Seismotectonic Study.

The project consists of identifying – based on existing surface and subsoil information – geological formations and structures with characteristics, geometric arrangement, and composition of their cover (shed) that enable them to be considered as potentially acceptable for CO₂ storage.

Establish the areas occupied by the pairs of formations identified (storage and shed), by analyzing geological data.

Specifying the position (location, limits) and geometry of potentially adequate structures and the suitability of their characteristics, incorporating subsoil information previously drawn up and analyzed in this or other projects.
