Uplift and erosion are complex phenomena in terms of their governing processes, precise
timing and exact magnitude. The intricate relationship between different geodynamic …

Low-resistivity shales are widely developed in the Sichuan Basin. The production of low-
resistivity shale gas reservoirs ranges from high to low to none. The existing methods for gas …

This study presents indirect methods of source rocks characterization by integrating
geochemical data with well logs and seismic inversion results. Well logs and seismic data …

At the Changning block and at the Luzhou block, the genetic mechanism of low-resistivity
shale and its impact on reservoir quality are currently a hot topic on a world-wide scale …

The Longyearbyen CO2 lab project was initiated in 2006 by the University Centre in
Svalbard (UNIS) to establish whether subsurface storage of locally produced CO2 is …

We consider marine controlled source electromagnetic (CSEM) data and demonstrate that a
typical CSEM survey is associated with significant data redundancy. Thus, it should be …

The phenomenon of low electrical logging response in gas shale reservoirs has become the
hotspot of deep layer investigation in the Southern Sichuan basin. Yet little attention has …

Two mathematical formulations are considered for calculating the time-domain
electromagnetic fields excited by a horizontal grounded-wire source in a 3D geological …

Accurate gas saturation calculations are critical to evaluating the production of marine shale
gas reservoirs. As a high-resolution exploration method, geophysical resistivity well-logging …

Seal integrity is a key property for petroleum exploration. This is even more the case in
uplifted basins, as exemplified by the northern Barents Shelf. Uplift may lead to fracturing …
