The primary objectives included evaluating the effectiveness of waterflood operations, understanding fluid dynamics in the reservoir, and assessing potential hydrocarbon recovery...

... 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...

... 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...

... 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...

... ABSTRACT The management of sand production in mature siliciclastic reservoirs is a recurring challenge, primarily stemming from the declining reservoir pressure as hydrocarbons are extracted over time. This phenomenon induces subsidence and compaction of reservoir rocks, which, in turn, can...

... 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...

... field experiencing production-related changes to reservoir fluid, the main objective of collecting AMG data is to aid early assessment of downhole hydrocarbon variability. For example, identifying reservoir tops, fluid dissimilarities, and an independent saturation flag is critical operational...

The percentage of connected vugs out of the total porosity, is in unison with the well flowing economical volumes of hydrocarbons. Also the portion of isolated vugs opens doors for Enhanced Oil...

... expert with specific skill sets. Formation fluid evaluation has traditionally used a traditional method that heavily relies on formation pressure measurements to calculate hydrocarbon volume and estimate and forecast reserves. This was accomplished by analyzing gradients and local fluid contacts...

The volumes associated with each cluster translates directly into the pore volumes corresponding to the different fluid components (e.g., heavy/light hydrocarbon, bound/free water) at each depth. We successfully verified the reliability...
