Sedimentary, Structural, and Migration Factors Improved Porosity and Permeability Values in Deposits Over the Basement Highs on the Nepa-botuoba Anteclise

Deposits in Ust-Kut horizons above the basement high are one of the most productive objects in carbonate sedimentary cover deposits in the territory of the Nepa-Botuoba Anteclise.

Despite the presence of search features expressed in the results of the seismic data, a unique model of the formation of the nature of improved porosity and permeability values does not yet exist.

The authors of the article analyzed the possible causes of the formation of improved properties in Ust-Kut horizons over the basement highs and formulated a conceptual model of the formation of deposits. The presence of improved porosity and permeability values in Ust-Kut horizons is associated with a combination of sedimentation, paleostructural and migration factors
