... indices and the fraction of water/hydrocarbon-wet beads is less than 20%. Moreover, we showed that water saturation can be estimated by interpretation of 2D-NMR measurements with average relative errors of less than 10%. The results clearly demonstrate that the introduced workflow can be used...

... characterization of carbonate rock pore structure. The method developed includes that we first calculate the volume fractions of crack pores (microcracks and microfractures with a low aspect ratio α ), reference pores (interparticle pores with a medium α ), and stiff pores (moldic and vuggy pores with an α...

.... ANALYSIS OF EXTRACTS OF CUTTINGS Extracts from cuttings represent very well the oil fractions, including the reservoir oil and the residual oil. Because water-based mud is used in the Troll field, it is feasible to use conventional geochemical analysis methods to study the oil fractions in the drill...

... fraction as an additional model parameter. Thus, the modeled dielectric dispersion is controlled by a few key petrophysical parameters: the water-filled porosity, the brine salinity, the water phase tortuosity exponents, and the trapped water fraction. Within our model construction, the trapped water...

...) biodegradation of oil (Mastalerz et al, 2018). Bitumen includes both extractable and non-extractable material, without a clear-cut boundary of solubility in organic solvents, such as toluene and dichloromethane; even in the same sample, some bitumen fractions are soluble and some are insoluble. The high-maturity...

... to reconcile models and actual measurements to solve for water saturation, reservoir gas and CO2 fractions in selected cases. The uncertainty of the outputs is also quantified by means of an ad-hoc Monte Carlo approach, starting from the standard uncertainties of the input PNL data. In turn, two real case...

... (T1LM) is used to characterize the average property of the T1 distribution. However, the presence of long T1 components makes the ROP effect more dominant. Therefore, a real-time flag is introduced that is activated when the porosity fraction of a long T1 component exceeds a certain threshold...
