A MUltiple Space and Time scale approach for the quAntification of deep saliNe formations for CO2 storaGe


The Heletz structure has been selected as a test site for a prospective CO2 reservoir and for the MUSTANG injection experiment based on the analysis of the available geological, geophysical and borehole data from various areas of Israel. The Heletz area is located in the Southern part of the Mediterranean Coastal Plain, about 7km from the sea shore.

Heletz site details:
  • The Heletz site located at the Southern Mediterranean Coastal Plain of Israel is a part of an oil field discovered in 1955 and since then developed by ~ 90 wells, ~ 40 of them within the Heletz structure.

  • The potential reservoir for CO2 storage consists of three Lower Cretaceous sand layers named ‘K’ ‘W’ and ‘A’ (see picture below).

  • The target layer is composed of sandstone, has a thickness of ~20 meters and is located at a depth of ~1500 m. Above it, an impervious layer (composed of clay) with a thickness of ~70 meters is present.

  • Hydraulic properties of the target layer are favorable: a porosity of ~15% and a permeability of ~1000-2000 mdarcy.

  • A number of abandoned wells penetrating this layer have been reviewed and are being considered as potential injection and monitoring wells.

Role of Heletz site in the MUSTANG project:

The Heletz site hosts the validation experiment. Partner GII undertakes a number of activities destined to integrate all the available information and provide the needed baseline information to the planning of the experiment. Work in Heletz consists of employing geophysical methods for reservoir characterization at the test site.


  • To gain understanding and develop methods to determine the two key trapping mechanisms of CO2 (residual trapping and dissolution trapping) at field scale, impact of heterogeneity.

  • Validation of predictive models, measurement and monitoring techniques.
Activities: Drilling of two wells: injection well and monitoring well.
