There are two gas migration mechanisms in the area: gas diffusion and gas advection. The gas in the caprock of Field A shows decreasing molecular weight trend from deep to shallow depths...

... saturated cores. First, relative permeability curves are calculated using the Johnson–Bossler–Naumann (JBN) method ( Johnson et al. 1959 ). Then, modified JBN model is defined to account for capillary pressure. Lastly, numerical simulator is used to generate relative permeability curves based on history...

... Aiming to improve the characterization of Carbonate Reservoirs from resource assessment to optimization of the static and dynamic modeling, we describe a holistic flowchart for an integrated approach by using the capillary pressure measurements. Its most innovative steps from pore scale...

... Capillary pressure and relative permeability are essential measurements that are directly affecting multi-phase fluid flow in porous media. The difficulty of calculating them rises being constrained to core analysis in the laboratory with many challenges of mimicking reservoir conditions...

... Abstract Capillary pressure and relative permeability are the two main factors determining the multiphase flow in oil and gas reservoirs. Dynamic capillarity, which includes the dynamic capillary pressure and the dynamic relative permeability, should be considered when performing waterflooding...

... hydrocarbon recovery. At the same time building and initializing a model based on different free water level positions across the field, zero capillary pressure, is challenging. Perched water contacts are the result of water entrapment during the hydrocarbon migration that could lead to variability in free...

... Abstract Capillary pressure is a crucial step in reservoir properties definition and distribution during static and dynamic modelling. It is a key input into saturation height modelling (SHM) process, understanding the fluid distribution and into reservoir rock typing process. Capillary...

... Abstract Spontaneous imbibition is an important process to increase oil recovery in fractured carbonate reservoirs. Due to the nano-scale pores and throats distributed in tight oil reservoirs, capillary pressure became much larger, which may result in a much stronger imbibition...

... of multiple wells. The analytical derivation assumes vertical equilibrium, in that any perturbation in the vertical direction is instantaneously equilibrated. Such an assumption gives maximum crossflow and therefore maximum upward and downward coning of the phases. The solution allows for capillary pressure...
