With a total installed energy capacity of 951 MWe (for 2018) and four developed geothermal fields, i.e. Cerro Prieto, Los Azufres, Los Humeros, and Las Tres Virgenes, Mexico is currently one of the top geothermal power producers worldwide. Installed geothermal power represents around 2% of the total installed electric capacity. In Mexico, the generation, transmission, and distribution of electric power are carried out by two public utilities i.e. the Comision Federal de Electricidad (CFE) and the Companıa de Luz y Fuerza (CLF).

This is the final post in the series on mapping in geothermal energy. We will focus on environmental and hazard mapping. In order to make any geothermal development sustainable, we must reduce its environmental impact and mitigate potential hazards. Even though emissions associated with geothermal exploration and development are small compared to fossil fuel power plants, there are other environmental concerns to be considered. The major environmental concerns associated with geothermal energy exploration and development includes:
Physical effects – Fluid withdrawal in natural man ..read more

The most important parameters obtained during drilling of any kind of geothermal well are temperature and pressure measurements. Currently available off-the-shelf logging equipment allow recording temperatures with a maximum of 350°C and approximately 4 hours of downhole operation time. A reliable system of temperature recording at extreme temperatures for any condition of a geothermal well is however not yet developed. As of today, several research projects, most commonly from EU-founded initiatives, focused on developing logging technologies for geothermal wells experiencing extreme temperat ..read more

Geothermal energy is a significant source of energy in Indonesia, where 40% of the world’s geothermal potential, estimated at 28,910 MW, is located across 312 locations on several islands such as Java, Sumatra, Bali, Nusa Tenggara, and Sulawesi. Indonesia, with its volcanic geology, ranks 3rd among all countries in the world, in utilizing geothermal power with its impressive 1,699 MW from geothermal power plants, which represents about 3.7 % of the country’s total electric power demand. (The United States and the Philippines are the two ahead of Indonesia). The abundance of geothermal re ..read more

Continuing from last week, we will look at indirect (structural) geophysical methods. These methods focus on geological parameters that indicate or reveal things important for understanding a geothermal system. These methods are focused on magnetic, gravity and seismic measurements.
Magnetic methods are widely used in geothermal exploration and focus on mapping changes in magnetism related to the distribution of magnetic minerals. Two main types of magnetism exist- Induced and remanent/permanent magnetization. The former is created by earth’s ambient magnetic field and the latter dominates in ..read more

Whether you follow an omnivore, pescatarian, vegetarian or vegan lifestyle – one thing’s for sure, you like food. So where does geothermal heat fit on your plate?
There is no doubt that a successful, large-scale geothermal project is lucrative, but project development time, undertaking legal clearances, policy inclusions, and acquiring adequate funding and shareholders can be lengthy. Comparatively, small-scale geothermal developments require only a fraction of the costs and downtime. Small-scale projects are not only focused on electricity generation, but they capitalize on all aspects of the ..read more

The use of geophysical methods for mapping in geosciences is widely accepted and has been utilized in oil and gas, mineral and geothermal industries. A vast number of geophysical methods exist and have been utilized in the geothermal industry. As such, we will cover geophysical mapping over two posts. Geophysical methods focus on measuring the physical properties of the earth. For geothermal energy, we study properties that are affected by temperature, fluid content, and structures influencing geothermal systems. Geophysical mapping in geothermal energy helps us to:
Assess the general propert ..read more

Terms ‘supercritical’, ‘superheated’ and ‘super-hot’ cause great confusion within the geothermal world. To date, there is no clear definition available of what is considered to be a ‘supercritical’ or ‘super-hot’ geothermal resource. In the Oxford English Dictionary, the word ‘supercritical’ is described as ‘relating to or denoting a fluid at a temperature and pressure greater than its critical temperature and pressure’; whereas, the Academic Press Dictionary of Science  ..read more

Geothermal energy in Germany is divided into shallow (below 400 m depth), medium (between 400 and 1000 m depth) and deep (below 1000 m depth and exceeding 60°C) resources. Other classifications include, open (connected directly to groundwater source) and closed (with no direct contact between circulating heat carrier and reservoir fluids) geothermal systems.
In the case of shallow resources, which are commonly exploited with heat pump systems, geothermal heat can be extracted from ground heat collectors, borehole heat exchangers (also in piles) or shallow groundwater wells. Energy from sh ..read more

Geochemical studies are vital for and often applied to every phase of geothermal exploration and development. From estimating subsurface temperatures during exploration to providing data on the water-to-steam ratio of the reservoir in production to identifying changes in geothermal fluids during production. Geochemistry is known for its graphs, charts and ternary diagrams (triangular graphs). But there are instances in the geothermal industry where we create geochemical maps.
In potential geothermal areas, it is important to carry out geochemical analysis of surface manifestations (hot/warm s ..read more
