The results showed that ignoring the adsorption and diffusion underestimated shale storage capacity while...

... Abstract We assess the huff-n-puff performance in ultratight reservoirs (shales) by conducting large-scale numerical simulations for a wide range of reservoir fluid types (retrograde condensate, volatile oil, black oil) and different injection gases (CO 2 , C 2 H 6 , C 3 H 8 ) by considering...

... for suspicion. Drohm et al. (1988b) do not reference or use the equilibrium criteria. Their "ideal" gas condensate (their Example 1) is actually a volatile oil, with maximum volume fraction liquid of 69.81%. Christensen (1999) did not explicitly discuss quality-checking lab data. Instead, he...

... Abstract History matching and subsequent forecasting work becomes a challenging task if limited supporting production data is available and the reservoir is severely depleted. For an offshore, volatile-oil reservoir, added to this challenge was an uncertainty in fluid PVT, where the data...

However, some North Sea Operators routinely offer farm-in opportunities where the probable resource estimates in their prospects, which are assumed to contain volatile oil, are broken down into oil, dry sales gas and NGLs...

... is only valid for linear systems. In practice, it is also used, with pseudo-pressures, for dry gas, and even for gas condensate and volatile oil below saturation pressure. As these systems are highly non-linear, there has been some concerns about the validity of such an approach. This paper investigates...

The FHZ EOS has been applied to different crude oil columns from volatile oil to black oil to mobile heavy oil all over the world to address key reservoir issues such as reservoir connectivity/compartmentalization, tar mat formation, nonequilibrium...

The next reservoir is the naturally fractured chalk reservoirs in the Ekofisk and Tor formations. Volatile oil is contained in the thick chalk sequence and has been developed by four horizontal wells...

The analysis of the set of K-values obtained in this manner provides the following additional advantages...
