... source. These are mapped to interpretable fluid types (e.g., clay-bound water, free water, hydrocarbons) based on their summit positions on the T1T2 Fluid Interpretation Mask, with support for fluid type customization. From the fluid volumes, key properties like hydrocarbon saturation, oil producibility...

Paper Number: SPWLA-2025-0081
... ABSTRACT Source and hydrocarbon migration continues to be one of the major uncertainties when exploring for hydrocarbons. In regions where high-quality source rock is less prevalent, the automatic evaluation of source rock quality and quantity can serve as a play opener and an important...

Paper Number: SPWLA-2025-0084
... ABSTRACT Evaluating hydrocarbon contact boundaries is essential for estimating the recoverable hydrocarbons in a reservoir. Measurements of quantitative C1-C5 gases along with higher molecular weight gases (above five carbons) such as aromatics and cycloalkanes using Advanced Mud Gas Logging...

... and 400 K. From the outputs of the simulations, density profiles and diffusion coefficients of the investigated molecules are quantified. We create quartz and illites surfaces containing fractions of 70 wt% and 30 wt% of water and hydrocarbon molecules respectively. Before adding CO 2 to the systems...

... distribution of the fluids as mapped from their resistivity values, however UDAR azimuthal resistivity images indicated laterally displaced hydrocarbons to the North-West of the wellbore. 3D UDAR Inversion was performed post-well to map the lateral distributions of the fluids. During real-time operations, 307...

... productivity. Laboratory higher frequency (HF), e.g., 23-MHz NMR techniques, especially two-dimensional (2D) T1-T2 mapping, and their applications have been essential for the noninvasive characterization of tight rock samples for identifying kerogen, bitumen, heavy or light hydrocarbons, and bound or capillary...

... hydrocarbon or gas charge into an oil reservoir or oil biodegradation-residue, e.g. at paleo oil-water contact (OWC). Heavy residual oil in many reservoirs can act as a permeability barrier and is a challenge for petrophysical evaluation using conventional logging tools. Asphaltene can be residual, immobile...
