Scaling the fluctuation of the flow capacity of core logs in a formation in southeastern Mexico

This study evaluates flow capacity fluctuations in well cores from a southeastern Mexico formation using pdpk records. Petrophysical measurements provide wellbore wall flow capacity data, used to identify trends. Applying a dynamic scaling approach akin to the Family-Vicsek method, we analyze discrete kh* records. In particular, the order parameter structure function q was applied to the flow capacity records, and the exponents characterizing dynamic scaling α, β, z were identified, revealing self-affine scalings for fluctuations. Data collapse of flow capacities occurs in the northern zone with higher fractures and oil production, contrasting with the poorly collapsed flow capacity in the southern zone. This suggests superior flow capacity in fractal reservoir media compared to Euclidean counterparts.
