Formation damage issues typically arise at different recovery stages of unconventional
oil/gas and geothermal energy in various petroleum and hydrological geosystems. A lack of …

A series of thick-wall cylinder tests were performed on Bentheim sandstone to investigate
the nucleation and propagation of borehole breakouts. Isotropic compression tests showed …

Sand production is one of the major research subjects in petroleum industry. This is usually
studied either by experimental or numerical methods. Experimental tests are usually focused …

Mechanism for slot-shaped borehole breakouts observed from drilling experiments in high-
porosity sandstone is investigated using the hybrid DEM-continuum mechanics modeling …

针对裂缝性地层水平井试油过程中井壁垮塌的问题, 建立了多弱面地层水平井裸眼井壁垮塌量
计算模型, 采用该模型分析了水平井裸眼井壁垮塌量的影响因素, 并通过现场应用将其与单弱面 …

The paper presents a numerical study on the erosion of sand particles where hydrodynamic
forces induced by liquid flow are considered to be dominant in a weakly bonded sand …

This paper presents the characterization of oil sands from the McMurray Formation. The
main objective of this paper is to investigate the possibility of replicating the oil sands by the …

Previous experimental observations have shown the formation of distinct failure patterns and
cavity shapes under different stress and flow conditions. With isotropic stress, spiral failure …

Designing an efficient drilling program is a key step for the development of an oil and/or gas
field. Variations in reservoir pressure, saturation and temperature, induced by reservoir …

Sand production is a common phenomenon during the extrusion of hydrocarbons, which
reduces production efficiency and brings about safety problems. A detailed knowledge of …
