West New Britain Province, which occupies the western part of New Britain Island in Papua New Guinea, is ideally located within an active tectonic region that influences volcanism creating an environment favourable for geothermal activity. Geothermal mapping of surface manifestations reveals high temperature geothermal prospects along the northern coastline of West New Britain Province that are further confirmed by geochemical analysis. The occurrence of geothermal features is confined to the Quaternary Kimbe Volcanics and alluvium in the lowland areas. The features in Talasea appear to be controlled by deep-seated northerly trending faults while structures in Hoskins also appear to be deep seated but have not been identified. The geothermal systems in West New Britain Province have not been drilled, but preliminary reconnaissance geothermal mapping and geochemical analysis reveals four high temperature geothermal prospects suitable for further investigation and development of geothermal energy. These are the Pangalu (Rabili) and Talasea Station geothermal prospects in Talasea and Kasiloli (Magouru) and Silanga (Bakama and Sakalu) geothermal prospects in Hoskins. The calculated reservoir temperatures for these fields are in the range of 245–310 °C. Recommendations are made for further follow-up exploratory investigations.
PLAY-BASED AND DATA OPTIMISATION GEOSCIENCE PROJECTS COMMISSIONED BY B. ILG Ilg, B.R., Davey, R. 2014, 2013 Compilation of published industry play-based exploration strategies, principal component analysis of the sample population and derivation of an NZP&M strategy for project funding, resource delineation, allocation, and promotion (in house).
Regions, countries and areas within countries compete against one another for investment from the global and regional markets when they allocate acreage and the rights for the exploration and production for energy and resources. This competition is driven by cumulative prospectivity (of all types) and is inhibited by cumulative risk (of all types). Higher cumulative prospectivity typically results in market tolerance of higher cumulative risk. The inverse is also true. Therefore, the goal of any regional, national or local programme in resource-related investment attraction should be the evaluation of prospectivity and risk, the strategic elevation of the former and the strategic reduction of the later wherever possible. The role of the coordinating entity in the geothermal energy context, can therefore be seen as assisting Nations in the optimisation of their respective cumulative country prospectivity in geothermal energy while simultaneously reducing country risk to investment. This approach has strong implications for policy at regional, national, and local scales. Entities and segments of the market have different tolerances for prospectivity and risk. These tolerances are often opaque within individual corporate strategies and even the market. In any case a consistent holistic market approach is preferred to a case by case investment approach. The former approach is offers more robust competitive allocation of rights and typically ensures better public good outcomes. The attached figure attempts to show this multidimensional environment in a singe graphic. Crucially it shows an ”awareness horizon”. If the wider market is unaware of positive attributes or trends investment attraction will be stifled. However, country risk data is widely available on line (e.g. ease of Doing Business and Corruption Index). In countries with challenging country risk profiles extra effort must be made to communicate favorable quantitative technical prospectivity to the market in order to offset the high above ground risk profile.
