... Abstract Smooth solid surfaces of reservoir rocks are assumed in formation evaluation, such as NMR petrophysics and reservoir wettability characterization through contact angle measurements. Measuring the degree of surface roughness, or smoothness, and evaluating its effects on formation...

... scoping, there is an ambition to increase formation evaluation value of information by leveraging drilling and mudlogging data, which traditionally often used in petrophysical or reservoir modelling workflow. Often data acquisition and formation evaluation for the shallow hole sections (or overburden...

The difference in formation properties and net-to-gross (NTG) are shown for both methods with the recommendation of 3D approach. log analysis Thickness sandstone interpretation well logging formation property formation evaluation horizontal well...

... and the effective porosity evaluation more difficult and even misleading during the formation evaluation step. The aim of this paper is to show through different case histories, how the various tool types can affect the formation evaluation model and a possible approach to mitigate the problem. The case study...

..., thus providing additional valuable information for formation evaluation. The new method is demonstrated by practical application in both synthetic and field examples of oil sampling in OBM. The synthetic examples demonstrate the robustness of the algorithm and show that the true formation and fluid...

... Abstract In current market conditions, performing logging operations as efficiently as practically feasible has become crucial to reduce the overall cost of formation evaluation. One of the most important formation evaluation parameters is hydrocarbon saturation. At the same time...
