Therm-Min™

Ana-Min offers a unique, high value mineral identification service for geothermal exploration, appraisal and development.​

 

 

Subsurface mapping of the geothermal system

Utilising Therm-Min™ Technology
​

As an extension of its mineralogy service (Geo-Min™), Ana-Min now offers a fast, effective and accurate service to identify key hydrothermal alteration minerals that are essential to mapping temperature and hydrology of viable geothermal “hot zones”.

​

Hydrothermal minerals indicate subsurface temperature distributions, thermal gradients, cooler vs hotter regions and zones of upwelling and recharge, permeable zones and barriers

Determining geothermal potential

  • Use mineralogy during exploration and appraisal drilling to ascertain if resource is large and hot enough for geothermal power
     

  • Recognise argillic assemblages which form low permeability seals over geothermal reservoirs
     

  • Map subsurface mineral zones to distinguish target hot zones from cooler compartmentalised zones
     

  • Mineralogy indicates presence of fracture mineralisation and high permeability fluid pathways

 

 

Facilitating geothermal operation efficiency 

 

  • Temperature ranges of minerals assist in estimating subsurface temperatures and setting of production casing depths
     

  • Facilitates optimal siting for next appraisal or production wells 
     

  • Allows prediction of scaling and corrosion problems
