We identify two interrelated but independent species of microcracks with different origins and different distributions. One species is the classic high-stress m
In heterogeneous natural gas reservoirs, gas is generally present as small patch-like pockets embedded in the water-saturated host matrix. This type of heteroge
Estimation of Thomsen’s anisotropic parameters is very important for accurate time-to-depth conversion and depth migration data processing. Compared with other
Seismic data with high signal-to-noise ratios (SNRs) are useful in reservoir exploration. To obtain high SNR seismic data, significant effort is required to ach
Tiltmeter mapping technology infers hydraulic fracture geometry by measuring fracture-induced rock deformation, which recorded by highly sensitive tiltmeters pl
Models that simulate the signature of single airguns form the basis for modeling the signals of airgun arrays. Most of the existing models assume that the air i
The Madden-Julian oscillation (MJO) is a dominant atmospheric low-frequency mode in the tropics. In this review article, recent progress in understanding the MJ
