Horizon are about to commence or currently working on the following new non exclusive studies:

Indonesia - East Java

Eastern East Java Sea: Fluid Inclusions Stratigraphy (FIS) Study
Fluid Inclusion Technologies and PT Horizon Geoconsulting, in association with MIGAS and PT Patra Nusa Data, is proposing a regional evaluation of petroleum charge in key wells from the East Java Sea, offered as a non-exclusive study. The foundation for this assessment will be fluid inclusion volatile analysis (Fluid Inclusion Stratigraphy or FIS) of over 4,000 samples from 15 wells. Detailed fluid inclusion petrography and API gravity determination will be included on selected sections that show significant FIS anomalies (possible migration pathways, paleo-hydrocarbon columns or present-day hydrocarbon columns). Use of these data will lead to better assessment of charge potential within nearby areas.

Classical geochemical techniques that analyze residual pore fluids are often inadequate for determining where petroleum fluids have been, and are typically hampered by contamination, fractionation and alteration issues. Subsurface fluid processes leave resolvable chemical traces in the form of crystallographically trapped fluids in diagenetic cements and healed microfractures. These fluid inclusions are not subject to evaporation during sample storage or loss of light ends during sampling from depth. They persist in the geological record long after the parent fluids have moved on, but are continuously formed even up to the very recent past. Hence, fluid inclusion studies have the potential to provide a detailed account of petroleum distribution and charge history.

Timor Leste

Timor Leste: Prospectivity Screening Study
Horizon plan to carry out a prospectivity screening study in association with the Energy & Minerals Resources Directorate of Timor Leste, which would provide a framework for hydrocarbon exploration in the area. The study would incorporate new analytical data on outcrop samples and hydrocarbon seeps from the area and integrate results of previous studies and published information.

The study would include the following:

  1. review of tectonic and structural evolution of area
  2. review of all available stratigraphic information to establish an initial chronostratigraphic framework for both offshore and onshore
  3. integration with regional seismic lines (ID92) establishing regional seismic interpretation from NWS to Timor Island
  4. additional fieldwork to identify and characterize source rock units and identify potential reservoir units onshore(note: although a significant amount of data is currently available new focused fieldwork is required to define the accurate location and stratigraphic relationships of the various rock units
  5. development of source and reservoir models using available data and drawing analogies with NWS and other Banda Arc areas
  6. documentation of Petroleum Systems Elements
  7. geochemical modeling to identify potential hydrocarbon kitchens
  8. discussion of tectonic influences on hydrocarbon migration and preservation
  9. discussion of implications for play types

Indonesia

Indonesian Coal Bed Methane Potential
The rapid growth of energy demand in Indonesia and the steady decline in oil production, together with the recognition by the Government of Indonesia of the need to secure domestic energy supply has led to increased interest in Coalbed Methane (CBM) potential. This untapped resource is believed to comprise ~450TCF of gas, a significant contribution to Indonesia total natural gas resources.

In an effort to stimulate the Coalbed Methane Industry the Government of Indonesia has signed 7 CBM contracts since 2007 and has plans to accelerate contract signing during 2009 and 2010.

In response to this interest Horizon is carrying out a two stage study of Coal Bed Methane resources in Indonesia. During Stage 1 a general review of the Coal Bed Methane potential of Indonesia is being carried out together with a review of exploration to date, fiscal and licensing terms. In parallel a detailed study of the Coal Bed Methane potential of the South Sumatra Basin is also underway. This draws on a wide range of data from surface geology and coal composition information to wireline logs and subsurface structure maps in order to identify coal bed methane play fairways and estimate potential recoverable reserves.

On completion of this work a similar study will be carried out on the Barito and Kutei Basins in Kalimantan.

The study is being carried out by CBM specialists in Australia utilizing local resources and data from Horizon.

On completion of Stage 1, expected during 4th quarter 2009, two reports will be published comprising a summary volume on Indonesian CBM Potential and the detailed report on South Sumatra.

The Kalimantan study will be completed during 2010.
