Lithofacies Characteristics of Point Bars and Their Control on Incremental Oil Recovery Distribution During Surfactant–Polymer Flooding: A Case Study from the Gudao Oilfield

Energies
Meandering river point bar sand bodies, serving as critical reservoir units, exhibit significant lithofacies heterogeneity that governs remaining oil distribution patterns.

Application of Lithofacies Models to Characterize Unconventional Shale Gas Reservoirs and Identify Optimal Completion Intervals

, 2010
Unconventional shale gas reservoirs are economically viable hydrocarbon prospects, and their development has rapidly increased in North America. These reservoirs must be routinely drilled horizontally and hydraulically fracture stimulated to maximize ...

Data-driven lithofacies prediction in complex tight sandstone reservoirs: a supervised workflow integrating clustering and classification models

Geomechanics and Geophysics for Geo-Energy and Geo-Resources
Lithofacies identification plays a pivotal role in understanding reservoir heterogeneity and optimizing production in tight sandstone reservoirs. In this study, we propose a novel supervised workflow aimed at accurately predicting lithofacies in complex ...

Depositional interpretation of lithofacies within the Purisima Formation.

, 2014
(A) lateral relationships of non-bonebed lithofacies, prior to bonebed formation. (B) Seafloor erosion during initial transgression; the massive pebbly sandstone (Spm) lithofacies is interpreted as representing proximal bonebed formation and the massive ...

Anisotropic velocity properties and lithofacies identification of shahejie lacustrine shales

Scientific Reports
Lacustrine shales have gained increasing attention in the global energy transition. However, their more complex lithofacies variations compared to marine shales pose significant challenges for precise reservoir characterization.

Pore-micro fracture structure, porosity and gas- bearing property of deep shale under lithofacies-formation pressure coupling

Scientific Reports
Formation pressure-lithofacies type are the most critical factors influencing micro pore structure and porosity in shale reservoir. However, how these two factors jointly affect shale gas accumulation remains unclear.

How lithofacies types in a reservoir analog facilitate reservoir quality assessment

, 2020
Lithofacies types present a means to characterize subsurface facies from description of the sedimentological inventory. While sedimentary structures and grain size can be assessed in core and outcrop, dimensions and lateral extension are best observed in
