Ensemble-Based Well Log Interpretation and Uncertainty Quantification for Geosteering
Nazanin Jahani, Joaquin Ambia Garrido, Sergey Alyaev +3
The costs for drilling offshore wells are high and hydrocarbons are often located in complex reservoir formations. To effectively produce from such reservoirs and reduce costs, opt…
A Deep Learning Approach to the Inversion of Borehole Resistivity Measurements
M. Shahriari, D. Pardo, A. Picón +3
We use borehole resistivity measurements to map the electrical properties of the subsurface and to increase the productivity of a reservoir. When used for geosteering purposes, it…
Application of effective medium theory to estimate gas permeability in tight-gas sandstones
Behzad Ghanbarian, Carlos Torres-Verdin, Larry W. Lake +1
Upscaling Klinkenberg-corrected gas permeability, k, in unconventional tight sandstones has numerous practical applications, particularly in gas exploration and production. In this…
Multidimensional NMR Inversion without Kronecker Products: Multilinear Inversion
David Medellín, Vivek R. Ravi, Carlos Torres-Verdín
Multidimensional NMR inversion using Kronecker products poses several challenges. First, kernel compression is only possible when the kernel matrices are separable, and in recent y…
