Exploration Challenges<br />
• Exploration Challenges<br />
– Spring directly above upflow from<br />
deep source (uncommon)<br />
– Outflow from source (common)<br />
– Hidden or blind systems (most<br />
common)<br />
• Results – significant drilling risk<br />
– Hot dry wells<br />
– Overturn in down-hole temperatures<br />
• Need better conceptual models to:<br />
– Locate areas of upflow<br />
– Avoid typically less productive<br />
outflow zones<br />
