Identification and Applications of Micro to Macroscale Shale Lithofacies
Journal of Nanoscience and Nanotechnology, 2021Systematic research and evaluations of shale gas reservoirs are critical in shale gas exploration and development. Previous studies in this field mainly depend on experimental analysis that is often overly simplified. Here, we report an integrated geological and engineering method that combines the lithofacies division system with an identification ...

Lithofacies recognition hybrid bench
Fifth International Conference on Hybrid Intelligent Systems (HIS'05), 2005Well offshore petroleum exploration is a risky, but very profitable task. Determining the rock formation of each layer of a given reservoir diminishes the risks of expending a great deal of money drilling dry wells. Since collecting offshore rock samples is difficult and expensive, geologists must decide upon drilling based on indirect measures called ...

Geostatistical Interpolation Constrained by Lithofacies
82nd EAGE Annual Conference & Exhibition, 2021Summary Geostatistical technologies, which include two-point geostatistics (TPS) and multiple-point geostatistics (MPS), are significant in both geological modelling and geophysical inversion. However, TPS is incapable to characterise complex geological structures, due to the dependency on the variogram.

Robust Unilateral Alignment for Subsurface Lithofacies Classification
IEEE Transactions on Geoscience and Remote Sensing, 2022Subsurface lithofacies classification refers to the way of establishing a classifier on the interpreted well logging data to predict the lithofacies types corresponding to the uninterpreted ones. Such a task has become a research focus by applying machine learning technologies under the assumption of independent and identical distribution. However, due

GLACIAL LANDFORMS, SEDIMENTS | Glacigenic Lithofacies
2007Glaciation has occurred episodically in Earth history since 2.8 billion years, most notably as the classic Ice Age/interglacials cycles of the recent geologic past (

Carbonate lithofacies as paleolatitude indicators: problems and limitations
Sedimentary Geology, 1988Abstract Detailed study of Miocene carbonates in the Mediterranean region and their analogues on modern carbonate shelves (in the Mediterranean Sea, Brazil and other areas) reveals at least three major types of carbonate platform lithofacies in addition to the classic tropical coral reef (chlorozoan) lithofacies: (a) chloralgal lithofacies, similar ...

Complicated Conglomerate Lithofacies and Their Effects on Hydrocarbons
Petroleum Science and Technology, 2014Conglomerates of Baikouquan Formation are fan-delta sedimentogenesis, and consist of coarse granules distributed near the source. Based on the sedimentary characteristics of the conglomerate the delta can be geographically divided into three areas: the fan-delta plain, fan-delta front, and pro-delta.

Characteristics and Evolution of Lithofacies Paleogeography
2020Similarities in global tectonics evolution and the unity of global sea level eustasy in the Paleozoic have provided a scientific foundation for sequence stratigraphy research. Since its development in 1987–1988, sequence stratigraphy has been applied in geological research worldwide with astonishing speed and breadth.

Lithofacies and Transport of Clastic Sediments in Karstic Aquifers
2004Karst aquifers demand continuous transport of clastic sediments if the conduit system is to remain open. Sediments are injected into the aquifer by sinking surface streams and through sinkholes, vertical shafts, open fractures, and other pathways from the land surface of sufficient aperture to permit gravity- and inwash-driven transport. Much transport

Integrated Lithofacies and Petrophysical Properties Simulation
SPE Western Regional Meeting, 1997Abstract This paper presents a new procedure that simultaneously generates consistent distributions of categorical lithofacies and continuous petrophysical properties, i.e., porosity and permeability. The technique used is the conditional simulation method which is capable of honoring the original distribution of ...
