Glossary

Anchor grouting

Concrete pumped into the rocks around the upper part of the well to anchor the well and well cellar to the near-surface rock formations.

Aquiclude

A geological formation (or formations) which will not transmit water; a barrier to vertical movement of geothermal fluid.

Aquifer

A geological formation (or formations) which contains water or geothermal fluid and will allow fluid movement.

Baseline

Data set acquired before exploitation begins, against which any future measurements are compared.

Benchmark

Permanent survey mark, often consisting of a stainless steel pin set in a concrete block or in the concrete base of a pipeline support.

Bleed

A well that is throttled back to a minimum flow is said to be “on bleed.” It is often risky to completely shut down a geothermal production well because it may be difficult to restart. Bleeding also keeps the wellbore heated which minimizes corrosion.

Deep liquid level

Boundary between the two-phase and deep liquid zones.
