Acoustic logging is a multidisciplinary technology involving basic theory, instrumentation,
and data processing/interpretation methodologies. The advancement of the technology now …

In 1996, we measured Stoneley-wave-induced electrical fields in an uncased water well
drilled in fractured granite and diorite near Hamilton, Massachusetts. Stoneley waves …

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

We tested two models, one for tube-wave generation and the other for tube-wave
attenuation at a fracture intersecting a borehole that can be used to estimate fracture …

In hard rock terrain, shallow water wells generally have a poor to moderate yield. Sinking
wells deeply to tap yielding fracture zones often backfires, because the borehole may miss …

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 …

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

复杂储层裂缝评价是储层研究的重要内容. 针对复杂储层现今裂缝有效性定量评价的难题,
通过阵列声波测井, 电成像测井提取的地应力及裂缝参数信息, 采用基于临界应力断层假说的 …

A method for determining properties of a transverse isotropic region of earth formations
traversed by a wellbore having substantially vertical and deviated sections therethrough …

We develop a series of analytical models that can be used to interpret Stoneley-wave
reflections from fractures intersecting a borehole, thus facilitating the determination of …
