Machine Learning for Fluid prediction (post-stack seismic data, Innovation Norway grant 2020/521538)
In May 2020, PSS-Geo with partners (CaMa Geo, AGGS AS, and Lime Petroleum Norway AS) was awarded an Innovation Norway grant to extend the current research project of Rune Inversion (Artificial Intelligence-based seismic inversion algorithm) for fluid prediction. The produced inverted volumes of P-wave velocity, Density, P-impedance, and their algebraical extension to Volume of Clay and Porosity, created a unique possibility to predict a type of fluid using ML algorithms.
Today, PSS-Geo is the holder of the unique dataset of seismic and well logs that gives the company a tremendous advantage in ML algorithms development for geo exploration.:
-
Seismic merge that is suitable for inversion (seamless, phase-controlled, with true amplitudes preservation)
-
Inverted seismic post-stack cube of 62 000km2: P-wave velocity, Density, P-impedance, Volume of Clay and Porosity
-
-
Accurate CPI database with a unique "fresh-water" logs estimation (300 wells)
-
Competence in Rock Physics, Seismic Processing, and Data science

The project participants have flexible possibilities to receive ML code, product (currently a prediction over the entire Norwegian Sea Shelf), and a product over the chosen area).
The basic principal of the algorithm can be investigated

Post-stack seismic data was inverted for P-wave velocity and Density using the Rune Inversion algorithm. The volume of clay was computed using Gyllenhamar's formula (from P-wave and Density), and porosity was computed using a standard approach. The produced volumes were used as recognition datasets, while 7 random wells' logs were used for learning. The results of the Machine Learning for fluid prediction are shown in Section 1 and Section 2.
