Various analysis methods including IR, SEM, contact angle determination and spontaneous
imbibition experiments were used to investigate the mechanism of wettability alteration of oil …

Coal masses in underground mines are in multiaxial stress states after excavation, and they
are frequently subjected to dynamic loads particularly from continuous mining-induced …

Existing methods of well-logging interpretation cannot be applied accurately for the
exploration and evaluation of carbonate reservoirs because of the fracture development …

The effects of joint spacing on the transmission characteristics of stress waves through
layered composite rock masses were investigated. First, a model of layered composite rock …

This study analyzes earthquake recordings from four near‐source (< 10 km) stations near
Fox Creek, Alberta, a region known for hydraulic fracturing‐induced seismicity. We examine …

Existing methods of well-logging interpretation often contain errors due to the presence of
subsurface fracture networks within carbonate reservoirs. The differences of frequency …

The behavior of ultrasonic waves in synthetic rocks consisting of alternating layers of sand-
based (porous and permeable) and acrylic (unporous) materials is investigated. Two …

Existing methods of well-logging interpretation often contain errors in the exploration and
evaluation of carbonate reservoirs due to the complex pore structures. The differences in …

This study investigates wave propagation of layered composite rock mass composed of
multiple joints and assorted rock materials. Firstly, the effect of multiple-reflection between …

We have designed transversely isotropic models containing penny-shaped rubber
inclusions, with the crack diameters ranging from 2.5 to 6.2 mm to study the influence of …
