It is shown the complete workflow, including the saturation calculation used to extract the hydrocarbon and/or filtrate signals from the T2 distribution. A comparison between both results is performed, showing...

... and defined differently for each rock type: residual oil saturation (SOWCR), connate water saturation (SWL), critical gas saturation (SGCR) and water relperm at residual oil saturation (KRWR) The following method was then chosen to determine the oil water contact using available log and core data. First were...

... Abstract Simulation of many enhanced oil recovery (EOR) methods such as water alternative gas (WAG) requires accurate determination of relative permeability (kr) data under different saturation histories. Relative permeability is a function of several factors such as wettability, spreading...

... mud filtrate invasion tends to be smaller. The dielectric tool was used in Petrobras to evaluate reservoirs with very high viscosity and fresh water, in which it showed good results in the quantification of water saturation and hydrocarbon mobility. Additionally, the tool was used in Pre-salt in order...

... with complex mineralogies and shales distributions, is detrimental to a proper saturation assessment with archie methods. The content of clay, thin laminations and small pore sizes add to the rock an important conductivity component that translates into low resistivity responses when measuring with low...

..., gas plays the role of reducing residual oil saturation while water controls, by multiphase flow-in-porous-medium effects, gas adverse mobility. In addition to the extra engineering tasks needed to design development plans and production facilities, an intense characterization programme should be put...

... test was performed under pressure conditions of 1000 psi, temperature of 63°C, and flow rate of 0.1 ml/min. The core sample was prepared at initial water saturation (Swi). This process was carried out by forced displacement and a vacuum procedure in the coreholder using synthetic formation water...
