Secondary and Tertiary Thermally Induced Gas-oil Gravity Drainage from Oil-wet Fractured Rocks: Experiments under Reservoir Conditions

Abstract: A series of reservoir condition experimental studies are presented that investigate the effects of oil production by water drive on the success of subsequent oil production by gas-oil gravity drainage in a fractured laboratory model. The experiments were performed using low permeable, oil-wet carbonate core samples. During this work, injection of N 2 gas followed by steam into the fracture was studied using two different scenarios: initial oil place at connate water saturation condition utilized for secondary … Show more

“…Many reservoir rocks are often oil-wet, e.g., shale and carbonates [Hirasaki and Zhang, 2004;Hassenkam et al, 2009;Asadizadeh et al, 2014;Xu and Dehghanpour, 2014].

“…We use an oil-wet silicon 2-D micromodel consisting of a monolayer of cylindrical grains representing a porous medium with porosity of = 0.51. Many reservoir rocks are often oil-wet, e.g., shale and carbonates [Hirasaki and Zhang, 2004;Hassenkam et al, 2009;Asadizadeh et al, 2014;Xu and Dehghanpour, 2014]. While the geometry and pore sizes are not representative for shale rock matrix (nanopores), they are relevant for damage zones, which include microfractures.…”
