Three simple methods for geothermal resource estimation—power density, stored heat, and
exergy—are reviewed and their shortcomings are discussed. The conclusion is that …

Geothermal is commonly considered to be a clean, green energy source but it does produce
some greenhouse gas emissions, particularly CO 2. The amount of CO 2 is usually …

We present case studies on two methods for quantifying uncertainty in predictions for highly
parameterised geothermal models. One method is fully linear, while the other is nonlinear as …

Waiwera is a new reservoir simulator designed to address the current and future challenges
posed by modelling geothermal systems. It incorporates several innovations aimed at …

The Krafla area in north Iceland hosts a high‐temperature geothermal system within a
volcanic caldera. Temperature measurements from boreholes drilled for power generation …

The Rotorua geothermal field is a shallow geothermal reservoir lying directly beneath
Rotorua Township in New Zealand. Temperatures of up to 200° C have been recorded at …

Geothermal energy resources are considered to be one of the main contributors to clean,
renewable and low-risk energy production. However geothermal power production may …

A new geothermal reservoir modelling framework is discussed. The framework has two main
objectives: first, all the geoscience and reservoir engineering data should be stored in a …

The need for numerical models for geothermal pressure transient analysis (PTA) is well
recognised. Conventional PTA is based on analytical models which usually do not work for …

Reinjection of excess water from the power production process in the Nesjavellir geothermal
field has increased the temperature of shallow groundwaters, posing a risk to cold water …
