Strength analysis of perforated casing in ultra-deep horizontal shale wells during sublevel acidizing and hydraulic fracturing process

open access: yesAdvances in Mechanical Engineering, 2022
In the process of sublevel acidizing and fracturing, the non-uniform load on production casing is complex, and casing failure occurs frequently, which seriously affects the next step of production, stimulation, and underground safety of the oil and gas ...

Using multiphase fluid flow modeling and time-lapse electromagnetics to improve 4D monitoring of CO 2 in an EOR reservoir [PDF]

open access: yes, 2018
Understanding the changes in the saturation within a reservoir undergoing enhanced oil recovery (EOR) is crucial to optimizing production. We debut a novel, multiphase fluid flow modelling code, TOGA, to assist in modeling gas, oil, and water phases ...

Sedimentology of reefal buildups of the Xiannüdong Formation (Cambrian Series 2), SW China

open access: yesJournal of Palaeogeography, 2019
The reefs in the Xiannüdong Formation (Cambrian Series 2) are the oldest archaeocyathan–microbial bioconstructions in China, but the details of their microbial structures have not been previously described.

A predictive model for the wettability of chalk

open access: yesSN Applied Sciences, 2020
Wettability is usually measured in special core analyses of limited plug samples according to typically costly and time-consuming procedures. For comparative purposes, wettability is considered an index.

Entanglement trapping in a non-stationary structured reservoir [PDF]

open access: yes, 2012
We study a single two-level atom interacting with a reservoir of modes defined by a reservoir structure function with a frequency gap. Using the pseudomodes technique, we derive the main features of a trapping state formed in the weak coupling regime ...

Optoelectronic Reservoir Computing [PDF]

open access: yesScientific Reports, 2012
Reservoir computing is a recently introduced, highly efficient bio-inspired approach for processing time dependent data. The basic scheme of reservoir computing consists of a non linear recurrent dynamical system coupled to a single input layer and a single output layer. Within these constraints many implementations are possible. Here we report an opto-

Iteratively Coupled Flow and Geomechanics in Fractured Poroelastic Reservoirs: A Phase Field Fracture Model

open access: yesGeofluids, 2021
Fluid-solid coupling in fractured reservoirs plays a critical role for optimizing and managing in energy and geophysical engineering. Computational difficulties associated with sharp fracture models motivate phase field fracture modeling.

Investigating electrical response to water saturation of Agbada sandstone in an x-field Niger delta, Nigeria [PDF]

open access: yes, 2019
In an attempt to characterize a reservoir in a field, importance is given to living models as it serves critical function in estimating if the reservoir under study is economically viable. Having a good knowledge of electrical response to reservoir rocks

Numerical Investigation of Hydraulic Fracture Propagation Morphology in the Conglomerate Reservoir

open access: yesGeofluids, 2022
The random distribution of gravels makes the conglomerate reservoir highly heterogeneous. A stress concentration occurs at the gravel-matrix interfaces owing to the embedded gravel and affects the local mechanical response significantly, making it ...
