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 ...

Ichnological insights into deoxygenation across the Cenomanian–Turonian Boundary Oceanic Anoxic Event 2 in the northern extent of Western Interior Seaway (west‐central Alberta)

Sedimentology, Volume 73, Issue 2, Page 355-390, February 2026.
ABSTRACT In‐depth ichnological and sedimentological analyses of the Cenomanian–Turonian boundary Oceanic Anoxic Event (OAE2) from the Western Interior Seaway of west‐central Alberta reveal a persistent physico‐chemically stressed setting. The interval is characterised by a dominantly diminutive and diminished ichnological assemblage, with familiar ...

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.

Classifying rock lithofacies using petrophysical data

Journal of Geophysics and Engineering, 2010
This study automates a type-curve technique for estimating the rock pore-geometric factor (λ) from capillary pressure measurements. The pore-geometric factor is determined by matching the actual rock capillary pressure versus wetting-phase saturation (Pc–Sw) profile with that obtained from the Brooks and Corey model (1966 J.

New Geochronological Constraints on the Late Palaeozoic Tarija Basin, Southern Bolivia: Tectonic and Palaeoclimatic Implications

Terra Nova, Volume 38, Issue 1, Page 9-18, February 2026.
ABSTRACT The Carboniferous‐Permian Tarija basin of southern Bolivia evolved under major tectonic and climatic influence. The timing of transition from glacially influenced to arid conditions, after the Gondwanide tectonic event, has been based mainly on palynological correlations.

Late Miocene-Early Pliocene Matemateaonga Formation in eastern Taranaki Peninsula: A new 1:50,000 geological map and stratigraphic framework [PDF]

, 2004
In recent years the Matemateaonga Formation has become an additional exploration play in Taranaki Basin. Exploration interest has been stimulated by the success of Swift Energy Company in the Rimu/Kauri prospect (38719), located near south Taranaki Coast.

A pairwise likelihood approach for the empirical estimation of the underlyingvariograms in the plurigaussian models

, 2015
The plurigaussian model is particularly suited to describe categorical regionalized variables. Starting from a simple principle, the thresh-olding of one or several Gaussian random fields (GRFs) to obtain categories, the plurigaussian model is well ...

3D modelling of the lithofacies architecture of the Great Oolite Group in the Cotswold Hills, Gloucestershire, England [PDF]

, 2013
The Great Oolite Group (Bathonian, Middle Jurassic) of the mid Cotswold Hills is a classic example of a limestone-dominated succession deposited on a carbonate ramp, with a range of distinct carbonate and subordinate siliciclastic facies belts which ...
