Successful Geostopping Using a Recently Developed LWD Look-Ahead Ultra-Deep EM Resistivity Tool

Autor: Jin Ma, Karol Riofrio, Nigel Clegg, Supriya Sinha, Hsu-Hsiang Wu, Artur Kotwicki, Torstein Skorve, Yngve Bolstad Johansen

Publikováno v: Day 2 Tue, November 01, 2022.

Geostopping is a critical operation due to wellbore-stability, well-control and HSE issues, requiring accuracy of a few meters. Reservoir boundary detection has previously been done with seismic applications and at-bit resistivity or near-bit gamma.

Dual Neural Network Architecture for Determining Permeability and Associated Uncertainty

Autor: Augustin Prado, Vasileios-Marios Gkortsas, Lalitha Venkataramanan, Ravinath Kausik, Yngve Bolstad Johansen, Harish Datir

Publikováno v: Petrophysics – The SPWLA Journal of Formation Evaluation and Reservoir Description. 62:122-134

The computation of permeability is vital for reservoir characterization because it is a key parameter in the reservoir models used for estimating and optimizing hydrocarbon production. Permeability is routinely predicted as a correlation from near-we

Analysis of Lateral Fluid Gradients From DFA Measurements and Simulation of Reservoir Fluid Mixing Processes Over Geologic Time

Autor: Yngve Bolstad Johansen, Soraya S. Betancourt, Vladislav Achourov, Qing Chen, Morten Kristensen, Oliver C. Mullins

Downhole fluid analysis (DFA) is one pillar of reservoir fluid geodynamics (RFG). DFA measurements provide both vertical and lateral fluid gradient data. These gradients, especially the asphaltene gradient derived from accurate optical density (OD) m

Automated well log depth matching: Late fusion multimodal deep learning

Autor: Veronica Alejandra Torres Caceres, Kenneth Duffaut, Anis Yazidi, Frank Westad, Yngve Bolstad Johansen

Publikováno v: Geophysical Prospecting

Petrophysical interpretation and optimal correlation extraction of different measurements require accurate well log depth matching. We have developed a supervised multimodal machine learning alternative for the task of simultaneously matching raw log

X-RAY DIFFRACTION, X-RAY FLUORESCENCE, AND NEUTRON INDUCED SPECTROSCOPY BASED CORRECTION TO IVAR AASEN GEOMODEL: AN OILFIELD FROM THE NORWEGIAN NORTH SEA

Autor: Yngve Bolstad Johansen, Tor-Ole Jøssund, Harish Datir, Egil Romsås Fjeldberg, Schlumberger, Geir Frode Kvilaas, Aker Bp, Lodve Hugo Olsborg

Publikováno v: SPWLA 62nd Annual Online Symposium Transactions.

The Ivar Aasen (IA) oilfield is located on the Gudrun Terrace on the eastern flank of the Viking Graben in the Norwegian North Sea. The field was discovered in 2008. The reservoir is located within a sedimentary sequence of Mid-Jurassic to Late-Trias

Reservoir Implications of Measured Thermodynamic Equilibrium of Crude Oil Components: Gases, Liquids, the Solid Asphaltenes, and Biomarkers

Autor: Julia C. Forsythe, Qing Chen, Oliver C. Mullins, Bita Bayestehparvin, Jesus Albert Cañas, Vladislav Achourov, Andrew E. Pomerantz, Li Chen, Yngve Bolstad Johansen, Soraya S. Betancourt

Publikováno v: Day 2 Tue, October 27, 2020.

The process of compositional equilibration of reservoir crude oil requires excellent reservoir connectivity. For example, the measured of asphaltene gradients for indications of connectivity is now commonplace. In addition, equilibrated fluids imply

In toluene, asphaltenes are dispersed as molecules at low concentrations, as nanoaggregates at moderate concentrations, and as clusters of nanoaggregates at high concentrations. These three asphaltene species are codified in the Yen–Mullins model.
