Abstract Two dedicated field experiments have been carried out at the Heletz, Israel pilot CO2 injection site. The objective has been to quantify the CO2 residual trapping in-situ, based on two distinctly different methods. Both experiments are based on the principle of a combination of hydraulic, thermal and/or tracer tests before and after creating the residually trapped zone of CO2 and using the difference in the responses of these tests to estimate the in-situ residual trapping. In Residual ...

At Heletz, Israel, pilot CO2 injection site two dedicated push-pull experiments have recently been carried out for quantifying the residual trapping in-situ and for comparing the results to values determined from core samples. The target reservoir has a total thickness of about 11m, located at a depth of 1.6 km. The first experiment, carried out in autumn 2016, is mainly based on hydraulic withdrawal tests before and after the creation of the residually trapped zone. In this experiment, the resi...

Abstract In order to evaluate chemical impacts of SO 2 impurity on reservoir rock during CO 2 capture and storage in deep saline aquifers, several batch reactor experiments were performed on laboratory scale using core rock samples from the pilot CO 2 injection site in Heletz. In this experiment, the samples were exposed to pure N 2 (g), pure CO 2 (g), and CO 2 (g) with an impurity of 1.5% SO 2 (g) under reservoir conditions for pressure and temperature (14.5 MPa, 60 °C). Based on the set-up and...

Carbon-based engineered nanoparticles have been widely used due to their small size and unique physical and chemical properties. At the same time, the toxic effects of these nanoparticles on human and fish cells have also been observed; therefore, their release and distribution into the surface and subsurface environment is a subject of concern. The aim of this research is to evaluate and compare the transports and retentions of two types of engineered nanoparticles (multiwalled carbon nanotubes...

Carbon-based nanoparticles (NPs) are commonly occurring, both with origin from natural sources such as fires, and in the form of man-made, engineered nanoparticles, manufactured and widely used in many applications due to their unique properties. Toxicity of carbonbased NPs has been observed, and their release and distribution into the environment is therefore a matter of concern. In this research, transport and retention of three types of carbon-based NPs in saturated porous media were investig...
