With help from horizontal wells and hydraulic fracturing, shale gas has made a significant
contribution to the energy supply. However, due to complex fracture networks and …

Distribution of volcanic reservoirs in Xujiaweizi half graben is controlled by both faults and
sealing layers where their integrity could have been compromised. This paper documents …

Being introduced in the last decade for proactive geosteering, directional resistivity logging-
while-drilling (DRLWD) measurements have been used to predict and invert formation …

As a geochemical parameter for characterizing source rock in shale gas reservoirs,
estimation of total organic carbon (TOC) is a main task of geophysical and geochemical …

We present systematic investigations on the physics, detection performance and inversion of
logging-while-drilling extra-deep azimuthal resistivity measurements (EDARM). First, the …
