**Exploration and Drilling**

## GRED ProgramGeothermal Resource Exploration & Definition

***Program Approach***
***Geographic Diversity Focus***
**GRED**
**New States, New Fields, Extensions**
**GRED II**
**New States, New Fields**
***Promote As Many Awards As Possible***
**Require Slim-Hole Drilling**
***DOE Cooperative Agreements***
**Preferred Contractual Instrument**
**Flexibility**

## GRED ProgramGeothermal Resource Exploration & Definition

***Scope of Work***
***Phase I***
**Exploration Work To Site A Test Well**
**Geologic Studies, Geophysics, Geothermometry**
***Phase II***
