Near Wellbore Hydraulic Fracture Propagation from Perforations in Tight Rocks: The Roles of Fracturing Fluid Viscosity and Injection Rate

open access: yesEnergies, 2017
Hydraulic fracture initiation and near wellbore propagation is governed by complex failure mechanisms, especially in cased perforated wellbores. Various parameters affect such mechanisms, including fracturing fluid viscosity and injection rate.

Exploring the propagation of hydraulic fracture with nonuniform stress based on the block distinct element method

open access: yesEnergy Science & Engineering, 2023
The stress field is a critical factor for fracture propagation in hydraulic fracturing. Attention should be paid to fracture propagation with the nonuniform stress field.

Probabilistic Forecasting of Hydraulic Fracturing-Induced Seismicity Using an Injection-Rate Driven ETAS Model

open access: yesSeismological Research Letters, 2021
The development of robust forecasts of human-induced seismicity is highly desirable to mitigate the effects of disturbing or damaging earthquakes. We assess the performance of a well-established statistical model, the epidemic-type aftershock sequence (

Impact of injection rate ramp-up on nucleation and arrest of dynamic fault slip

open access: yesGeomechanics and Geophysics for Geo-Energy and Geo-Resources, 2021
Fluid injection into underground formations reactivates preexisting geological discontinuities such as faults or fractures. In this work, we investigate the impact of injection rate ramp-up present in many standard injection protocols on the nucleation ...

Effect of fluid injection rate on the hydraulic fracture propagation characteristics

open access: yesIOP Conference Series: Earth and Environment, 2021
Numerical simulations using UDEC were performed to better understand the role of fluid injection rate on hydraulic fracture evolution characteristics and the associated changes in the in-situ stress field.

Relating Dike Geometry and Injection Rate in Analogue Flux-Driven Experiments

open access: yesFrontiers in Earth Science, 2021
Dikes feed most eruptions, so understanding their mechanism of propagation is fundamental for volcanic hazard assessment. The variation in geometry of a propagating dike as a function of the injection rate remains poorly studied.

Parametric Study of Injection Rates With Solenoid Injectors in an Injection Quantity and Rate Measuring Device [PDF]

open access: yesVolume 1: Large Bore Engines; Fuels; Advanced Combustion; Emissions Control Systems, 2014
The rate at which fuel is injected into the cylinder of a direct injection Diesel engine has significant implications for the ensuing mixture formation and combustion processes. Advances in fuel injector technology enable a variety of advanced injection strategies, particularly very closely coupled injection events.

Polymer flooding effect of seepage characteristics of the second tertiary combined model of L oilfield block B

open access: yesJournal of Hebei University of Science and Technology, 2015
The second tertiary combined model is applied to develop the second and third type reservoirs which have more oil layer quantity and strong anisotropism, compared to the regular main reservoir with polymer injection, whose seepage characteristics of ...

A rate-of-injection model for predicting single and double injection with or without fusion

open access: yesInternational Journal of Engine Research, 2023
Models used to predict the instantaneous injected fuel mass are of varied interest in automotive applications, including for providing inputs to CFD calculations or for engine control. While multiple injection strategies are now commonly used in diesel engines, the overall approach may be susceptible to injection fusion, which is defined as two ...
