Study of wellbore instability in shale formation considering the effect of hydration on strength weakening

Frontiers in Earth Science
Shale formations often contain a high proportion of clay minerals, which, upon contact with drilling fluid, undergo hydration expansion. This leads to wellbore instability, a problem that poses significant challenges globally.

Development of a numerical workflow based on μ-CT imaging for the determination of capillary pressure-saturation-specific interfacial area relationship in 2-phase flow pore-scale porous-media systems: A case study on Heletz sandstone [PDF]

, 2016
In this case study, we present the implementation of a finite element method (FEM)-based numerical pore-scale model that is able to track and quantify the propagating fluid–fluid interfacial area on highly complex micro-computed tomography (μ-CT ...

UFM‐Based Simulation of Competitive Multi‐Fracture Propagation in Horizontal Wells

Energy Science &Engineering, Volume 13, Issue 12, Page 6069-6083, December 2025.
Simulation schematic of Competitive Multi‐Fracture Propagation in Horizontal Wells. ABSTRACT Multi‐stage hydraulic fracturing in horizontal wells is vital for stimulating unconventional reservoirs, yet uneven fracture propagation often restricts the effective communication volume of the reservoir.

Numerical Simulations of Hydraulic Fracturing in Carbonate‐Type Hot Dry Rock Reservoirs Based on the Coupled Thermo‐Hydraulic‐Mechanical‐Damage (THMD) Model

Energy Science &Engineering, Volume 13, Issue 12, Page 5821-5834, December 2025.
ABSTRACT Hydraulic fracturing technology is widely used in Enhanced Geothermal System (EGS) projects to induce fractures and enhance the permeability of thermal reservoirs. The hydraulic fracturing process of hot dry rock (HDR) is actually a multiphysics coupling process that couples the heat transfer field, seepage field, stress field, and damage ...

CONTRIBUTION TO THE METHODOLOGY OF DETERMINING THE OPTIMUM MUD DENSITY - A CASE STUDY FROM THE OFFSHORE GAS CONDENSATE FIELD D IN THE PERSIAN GULF

Rudarsko-geološko-naftni Zbornik, 2018
Drilling the wells using water based mud through shale formations, causes their exposure to serious time-dependent wellbore instability due to shale swelling.

Data on shale-water based drilling fluid interaction for drilling operation [PDF]

, 2018
The shale dispersion test (rolling test) is a common procedure that is used to measure the interactions between drilling fluids and shales. The shale rolling test depends on the moisture content of the shale, the shale composition, the viscosity of the ...

Fluid Pressure Diffusion and Elastic Stress Transfer From Seismic Slip Control Slip Front Expansion in Fluid‐Driven Swarm Seismicity

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 12, December 2025.
Abstract Observations of fluid‐driven swarm seismicity expanding with the same diffusive space‐time behavior as analytical solutions for aseismic slip have been interpreted as evidence that stress changes from aseismic slip trigger seismic slip. In some cases, aseismic slip is confirmed from crustal deformation measurements or sheared wellbore casing ...
