An Improved Model to Simulate Mud (Drilling Fluid) Dispersion through Porous Media [PDF]

open access: yesIranian Journal of Chemistry & Chemical Engineering, 2010
An improved model of mud dispersion has been introduced in this work. The advantages of this model consist of a new analytical correlation for dispersivity by using resistivity log data and using a new aspect of capacitance dispersion model. Mathematical

International Environmental Agreements in the Presence of Adaptation [PDF]

open access: yes
We show that adaptive measures undertaken by countries in the face of climate change, apart from directly reducing the damage caused by climate change, may also indirectly mitigate greenhouse gas emissions by increasing the stable size of international ...

Analysis of Geological Characteristics and Reservoir Potential Formation Damage Factors of Shallow Low‐Temperature Low‐Pressure Low‐Permeability Sandstone Reservoir

open access: yesEnergy Science & Engineering
The C‐S reservoir in the YQ district of Ordos basin, China, is located at a relatively shallow depth (240–720 m), with an original pressure coefficient of approximately 0.85 for the oil layer.

Analysis of damage mechanisms and controlling factors of fine particle migration in unconsolidated sandstone reservoirs based on reservoir classification

open access: yesEnergy Science & Engineering
Particle migration in oil and gas reservoirs is a common phenomenon in the process of oil and gas development, and is considered to be an important reason for the damage of reservoir permeability and the reduction of oil and gas productivity.

Semiconductor structural damage attendant to contact formation in III-V solar cells [PDF]

open access: yes
In order to keep the resistive losses in solar cells to a minimum, it is often necessary for the ohmic contacts to be heat treated to lower the metal-semiconductor contact resistivity to acceptable values. Sintering of the contacts, however can result in

FEA modeling of orthogonal cutting of steel: a review [PDF]

open access: yes, 2012
Orthogonal cutting is probably the most studied machining operation for metals. Its simulation with the Finite Element Analysis (FEA) method is of paramount academic interest.
