Heletz (Israel) site will be the main injection site of TRUST in terms of performing the experiments for the
very objectives of the project and as part of the project budget. This is a site built up in the frame
of the
ongoing (2009-2013) EU FP7 project MUSTANG (www.co2mustang.eu) with two deep drilled wells along with extensive
instrumentation and sampling systems. Small scale injection experiments (both single-well and two-well tests)
are already carried out there in the frame of the MUSTANG project, with the primary objectives:
(i) to gain understanding and develop methods to determine the two key trapping mechanisms of CO2 (residual trapping and dissolution trapping) at field scale.
(ii) to look at the impact of heterogeneity in the field scale.
(iii) to provide data for the validation of predictive models as well as measurement and monitoring techniques.
In the frame of TRUST the injections will be continued with larger amounts of CO2, by testing the performance of various modes and strategies of injection and with more advanced monitoring methodologies. Heletz is a depleted oil field (which produced 20 million barrels of oil) with saline water on its edges. The bearing layers are the “Heletz sands” with a cumulative thickness of ~10 m at a depth of ~1,650 m. Above the producing layer there is a caprock layer of ~40 m thickness. Due to its small thickness, the site is ideal for testing different modes of injection as even smaller amounts of injected CO2 will produce noticeable responses and footprints.
