Purpose and Goals of Study<br />
• Tie surface geology to subsurface using old<br />
fashioned field work and cutting edge workstation<br />
technology.<br />
• Determine individual fault block geometries and<br />
fault sealing character.<br />
• Identify new primary potential production from<br />
undrained d fracture systems and fault blocks.
