Permeability reduction and formation damage in porous media caused by fines (defined as
unconfined solid particles present in the pore spaces) migration is one of the major reasons …

Coal fines can substantially influence coal seam gas reservoir permeability, thus impeding
the flow of gas in coal microstructure. The coal fines generation and migration are influenced …

The successful pilot testing of depressurization production for natural gas hydrate reservoir
was conducted at Shenhu Area in the South China Sea. However, pressure changes due to …

A triaxial creep model for deep coal considering temperature effect based on fractional
derivative is proposed for the condition of triaxial stress state. In order to study the …

This paper presents CO 2-brine wettability of sandstones and minerals composing the
sandstones. The measured contact angles are used further to analyse the effect of wettability …

In coal mining industry, with the depth growing of coal mines, the creep behaviours of coal
and rock can extensively affect the mining safety, coalbed methane recovery and geo …

Lost circulation induced by working fluid loss into formation fractures often leads to safety,
environmental and economic issues, which has hindered the exploitation of oil, gas and …

Hydraulic fracturing is the main stimulation technique that enables the economic production
of coalbed methane reservoirs. However, massive invasion and retention of coal fines in …

Enhanced oil recovery by low-salinity waterflooding (LSW) has been shown to result from
the combined effect of various physical mechanisms. In this study, laboratory experiments …

Matrix shrinkage is a unique property of coal which dictates the sorption induced strain in the
constitutive relation. Both permeability and stress profiles are passively modified with …
