A comprehensive assessment of the fracturing and blockiness of the gabbro of the Pshenychne deposit

open access: yesТехнічна інженерія, 2023
In order to ensure the correct development of the deposit and to use the effective technologies for stone extraction, it is necessary to carry out a comprehensive assessment of the structural properties of the massif, in particular, to perform a study of

Mechanical property design method of cement sheath in a horizontal shale oil well under fracturing conditions

open access: yesPetroleum Exploration and Development, 2022
Based on the elastoplastic model of cement sheath considering the influence of three-dimensional principal stress and the stress field model of interface crack, a mechanical performance design method of cement sheath is established to meet the wellbore ...

Fractured meshes

open access: yesFinite Elements in Analysis and Design, 2023
This work introduces “generalized meshes”, a type of meshes suited for the discretization of partial differential equations in non-regular geometries. Generalized meshes extend regular simplicial meshes by allowing for overlapping elements and more flexible adjacency relations.

Pore structure and fractal analysis of coal subjected to multiple treatments based on nuclear magnetic resonance

open access: yesEnergy Science & Engineering, 2022
Microwave heating (MW) and freeze fracturing (FF) have been widely used for enhancing the permeability of coal reservoirs. In this paper, the effects of combined MW–FF treatments on coals are experimentally investigated through nuclear magnetic resonance.

Geomechanics of Unconventional Reservoirs: Hydraulic Fracturing and Nanoindentation [PDF]

open access: yes, 2021
Geomechanics is the study of the mechanical response of geologic formations subjected to injection, production, and storage of fluids in the subsurface. It plays a role in understanding formation integrity and the response to oil and gas depletion during

Interference fracturing: Nonuniform distributions of perforation clusters that promote simultaneous growth of multiple hydraulic fractures [PDF]

open access: yes, 2015
One of the important hurdles in horizontal-well stimulation is the generation of hydraulic fractures (HFs) from all perforation clusters within a given stage, despite the challenges posed by stress shadowing and reservoir variability.
