| Summary: | The core objective of this project was
to develop a sufficiently large database to allow
statistically significant conclusions to be drawn on the
success rates of geothermal wells worldwide (expressed as
the number of successful wells developed as a proportion of
total wells drilled in any given field). This report
determines and analyzes that overall success rate, as well
as those factors that potentially affect success including
geology, resource enthalpy, and well depth. It seeks to
assess the extent of any improvements in well success rates,
and how far the likelihood of success increases as a
developer learns more about any specific resource. This
report also analyzes the power capacity of geothermal wells
drilled and the factors affecting such capacity. This report
is targeted at those with an interest in the risks
pertaining to geothermal wells, and the subsequent
probability of success. The information contained is of
interest to geothermal developers, and to financers engaged
in the risk assessment of such projects. This report, and
the database and analysis on which it is based, may be used
by stakeholders in the geothermal industry investigating the
range of success rates seen in geothermal projects around
the world, and the factors that influence such variation. |
