St Kitts Geothermal ProjectGGA Conference – WFES 2017

ADNEC - Abu Dhabi, UAE18th September 2017

REVEAL YOURGEOTHERMAL POTENTIAL

GGA Conference - WFES Abu Dhabi - 18.01.2017

• French Geothermal Company homebased in the Caribbean & France

• Providing engineering services to qualify & manage Geothermal resources: Geosciences Project Development

• Focus on LAC region & SIDS

Who are we


Our expertise

1. Data acquisition & processing

2. Conceptual modeling

3. Simulations

4. Resource assessment & Drilling program


• Teranov is lead partner & coordinator of

French Geothermal Research Program (40 MUS$) to develop innovative methodologies and expert tools to better characterize geothermal resource Supported and co-financed by the French Gov 2 private partners associated with Top 10 French Universities

& Research Labs totaling 50 geoscientists:

Our Geoscience organisation


• The Gov. of the Federation of St Kitts & Nevis and Teranov entered into a Memorandum of Understanding and a Roadmap in sept 2015

• The MoU covers the geothermal development from A to Z: The exploration phase The development and construction phase The long term exploitation phase

• The Roadmap sets: The agenda & the objectives The partners’ contributions The legislative framework modifications (Dec 2015)

• Main partners’ engagements: Build broad support for the project as well as to manage public expectations Provide open and transparent communication at each phase of the project

Public Private Partnership


• Previous Caribbean regional preliminary studies, including GeothermicaItaliana in 1992, have identified two main areas of interest on St Kitts, which remained unexplored until now due to the lack of surface manifestation:

• North-Western area was favored considering:

Existing data/analysis Surface manifestations Land use

Background and areas of interest

95°C

a : 50°C


• Geological field survey implemented• Rock sampling & petrological analysis implemented• Review of the geological map done

Surface studies: Geology


• Samplings realized: Ground water Surface and sea water Gas and ground gas

• Temperature assessment of the reservoir : 212°C

Surface studies: Geochemistry


• Gravimetric: Acquisition of 300 measurement points for this survey Validates structures

Surface studies: Geophysics 1


• Magnetism: Acquisition: drone and boat Validates structures



• InfraRed: Acquisition: Drone Assess thermal flow

at the sea resurgence



• Magnetotelluric (MT): 80 MT soundings were recorded - 60 MT pointsused for the model Models developed :

• 1D and 3D Resistivity models• 3D MT-GRAV joint Inversion model


Sandy point village


• Based on: Geology Field observations Digitalized Elevation Model Magnetism Gravimetry

Surface studies: Structural analysis 1


• Essential input for: Understanding of the revervoir geometry and control Identification and optimisation of the drilling targets

Surface studies: Structural analysis 2


• Inputs for the reservoir capacity estimate: Reservoir geometry Temperature Porosity Conversion factors

• Establish conceptual model of the reservoir

Surface studies: Ressource assessment 1

Upflow zone 200°C

SW-NE section including fumaroles


• Resource estimate using the stored heat method following the Australian code net of power plant losses (-10%) but without pumping losses

• Probabilistic estimation: Resource estimation between 18 to 36 MWe P50 estimation of the plant capacity = 27 MWe P90 = 18 MWe meaning that according to our analysis and based on available surface data, 90% of chance to have more than 18 Mwe

• Complete 3G exploration works are currently under independant Peer Review process by GRG (USA).

Surface studies: Ressource assessment 2


Project implementation: next steps

• Next major project milestones: Geothermal Agreement signature in March Exploratory drilling financing to be completed Full Environmental and social Impact Assessment - Public awareness Exploratory drilling and final resource assessment
