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.

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.

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 ...

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.

Analytical and numerical investigation of escape rate for a noise driven bath [PDF]

open access: yes, 2001
We consider a system-reservoir model where the reservoir is modulated by an external noise. Both the internal noise of the reservoir and the external noise are stationary, Gaussian and are characterized by arbitrary decaying correlation functions.

Experimental study of shale drillability with different bedding inclinations under varying wellbore pressure conditions

open access: yesJournal of Petroleum Exploration and Production Technology, 2021
In the practice of shale gas development engineering, it is important to understand the physical and mechanical properties of shale. The bedding inclinations of shale are known to significantly influence its physical and mechanical properties. This study

Modelling Reservoir Computing with the Discrete Nonlinear Schr\"odinger Equation

open access: yes, 2018
We formulate, using the discrete nonlinear Schroedinger equation (DNLS), a general approach to encode and process information based on reservoir computing. Reservoir computing is a promising avenue for realizing neuromorphic computing devices.

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 ...
